The Lie of Eskrador

I. The Chronicler

Chronicler Ptolan Vaas had spent his whole life as an Astartes preserving truths that nobody could question any more — until the Primarch himself returned and every single one of them was suddenly open again.

He sat in the seventh level of the Index Athanaeum, deep beneath the fortress of Macragge, surrounded by ten thousand years of chronicle script, when the commission arrived that would shortly afterwards have him lay the official chronicle of the battle of Eskrador beside a contradictory transcript. The Index itself was one of the most venerable institutions of the Ultramarines — a library larger than some hive cities, in which every battle, every campaign, every death of a brother since the founding of the Chapter was recorded in careful, incorruptible script. Vaas had served forty years in its passages, first as an apprentice, then as a full chronicler, responsible for the accuracy of records that generations of brothers studied as incontrovertible truth.

His present task was, at first sight, of a bureaucratic nature: since the return of the Primarch Roboute Guilliman several years before, the Index had begun to pursue an unprecedented project — the systematic checking of every historical chronicle of the ten-thousand-year gap against the personal recollections of the Primarch himself, wherever he was prepared to share them. For ten millennia the Ultramarines had reconstructed their own history at second hand, from fragmentary reports, from conjecture, from what survivors had still been able to utter in their last moments. Now, for the first time, there existed a living witness to almost the whole span — a witness whose memory, as Vaas had learned in recent months, was more precise than any archive the Chapter had ever possessed.

Vaas had been twenty-nine years old, a promising young warrior of the Second Company, when a wound during the reconquest of Parmenio abruptly ended his active fighting career — not so severe as to have endangered his life, but severe enough that the Apothecaries of the Chapter decided to seek his long-term employment in a less physically demanding service. He had at first felt that decision to be a defeat, a quiet shame he spoke of to nobody, but which accompanied him like a shadow through the first years of his new service in the Index Athanaeum. Only with time, as he learned how much responsibility actually lay in the preservation of truth, had he begun to understand his new role not as a withdrawal from real service but as another, equally necessary form of it. The decisive moment of that change had been a night in his third year in the Index Athanaeum, when he read a report about a fallen brother from the time of the Indomitus Crusades — a man whose last deeds would otherwise have been lost for ever, had a chronicler like Vaas not carefully reconstructed them from fragmentary testimony. In that moment he had understood that memory itself was a form of service, as honourable as the sword of a battle-brother, even if it expressed itself in quieter, less visible deeds.

It was an awe-inspiring task, and Vaas had approached it with the same methodical devotion every task of his office demanded. He had begun with the smaller discrepancies — wrongly dated battles, confused unit names, small exaggerations that had crept in over millennia of transmission. None of it had prepared him for what he discovered this morning, when he laid the official chronicle of the battle of Eskrador beside a newly released transcript — a conversation the Primarch had personally held with the Chief Chronicler three months before, in which he mentioned, in passing as it seemed, details that contradicted the official record in a way no mere error of transmission could explain.

Vaas laid the two documents side by side on his reading table, his hands, despite his Astartes discipline, hesitating involuntarily before he compared them a third time.

The official chronicle, composed by chroniclers who had lived two centuries after the events themselves, on the basis of transmitted oral reports, described the battle of Eskrador with the accustomed epic clarity of Imperial historiography: Guilliman breaking the methodical caution of his own doctrine to lead his elite units in a desperate, unexpected assault on the headquarters of the Alpha Legion; the personal duel with Alpharius that ended with the death of the traitor Primarch; the subsequent burning of the body on a great pyre, before the eyes of the assembled Ultramarines, as final proof of the victory.

The chronicler who had personally held that conversation with the Primarch — a greatly aged brother named Chief Chronicler Halvorn, whose own career already numbered eight centuries — had, as Vaas gathered from an attached marginal note, evidently not himself noticed what significance the Primarch's passing remarks possessed. He had simply transcribed them, with the professional distance of a man too accustomed to recording historical testimony to weigh every single detail at once against the whole weight of the existing chronicle. It had needed a fresher eye, less burdened by the weight of tradition — Vaas's own eye — to notice the discrepancy at all.

Guilliman himself, in the transcript of the conversation with the Chief Chronicler, remembered the battle differently — not in great contradictions, but in small, uncomfortable details that Vaas's trained eye at once recognised as significant. The Primarch remembered that he had found the duel itself strangely easy, easier than he would have expected from an opponent whose Legion was notorious for its unpredictability. He remembered that his opponent, in the last moments before the fatal thrust, had said something that Guilliman had never entirely deciphered — not the despair of a dying man, but something that sounded more like a last, private observation, addressed to nobody but himself. And, most disquieting of all: Guilliman remembered that he had not personally supervised the burning of the body — that, exhausted by the battle and already occupied with the organisation of the withdrawal, he had left the task to his Apothecaries, and that he could not remember with certainty whether he had seen the dead Primarch with his own eyes a second time before the flames consumed him.

In the margin of the transcript there was a handwritten note by the Chief Chronicler Halvorn himself, evidently intended as a private marginal remark, never meant for the official chronicle: The Primarch seemed himself surprised by this gap in his memory, as though he were fully realising it for the first time during our conversation. He asked me not to include this part of the conversation in the official report, "until there is more clarity". I have complied with his wish, but I note it here, for my own records, should the question ever arise again.

Vaas read this marginal remark with growing excitement. Here was proof that he was not the first to have noticed this discrepancy — that even the Chief Chronicler, in a moment of openness, had felt the same doubt that Vaas was now beginning to investigate himself.

He thought of the countless times he had himself read this official chronicle aloud to young aspirants, in the ceremonial lessons every novice of the Chapter passed through before he attained the rank of a full Astartes — how he had spoken the words about the victory on Eskrador with the same unshakeable certainty with which he spoke about the founding of the Chapter itself. How many generations of Ultramarines, he asked himself, had carried that story within them as the foundation of their own understanding of victory and sacrifice, without ever suspecting that the foundation itself might be built on sand?

Vaas sat still a long time, the two documents before him, and felt a question forming in him that in forty years as a chronicler he had never had to put: what if the history his whole Chapter had regarded as closed for ten thousand years had in fact never been closed at all?

II. The Rift in the Report

He spent the next three days gathering every available fragment about the battle of Eskrador, with a thoroughness unusual even for his own high standards. He worked mostly alone, in the late hours, when the other chroniclers of the Index Athanaeum had withdrawn to their meditation cells, out of an instinct he did not himself fully understand at first — a growing caution telling him that this inquiry, early as it still was, was better pursued in concealment until he himself had a clearer picture of what he was actually dealing with. He searched the marginal notes of long-dead chroniclers, the field reports of the surviving companies, the sparse mentions in the chronicles of other Chapters that had happened to hear of the battle.

What he found disquieted him more with every further document.

The original field reports — not the later, smoothed official chronicle, but the raw, immediate dispatches of the unit commanders on the spot — contained contradictions that had been silently smoothed over in the final version. A captain named Ancaeus reported that the body he saw on the pyre "appeared smaller than the reports of Alpharius's stature suggested" — an observation entirely absent from the official chronicle. An Apothecary named Sennian, whose full report Vaas found after hours of searching in a seldom-consulted branch of the archive, mentioned that the genetic verification of the body "could not be carried out with complete certainty owing to the extreme damage from the preceding engagement" — a formulation whose bureaucratic reserve laid a bomb under ten thousand years of certainty.

Vaas read that one sentence at least a dozen times, each time with growing unease, imagining how many generations of chroniclers before him had read the same words and, for whatever reasons, never recognised the full import of their meaning. Had it been mere negligence, a detail lost in the turmoil of post-war documentation? Or had somebody, with full intent, buried that one decisive formulation so that only an exceptionally thorough successor would ever find it again?

He also found, in an almost forgotten appendix to the troop movement lists, an inconsistency that in itself would have seemed meaningless, but that in the context of the other discoveries supplied a further piece of the puzzle: the number of witnesses present at the final burning ceremony was given in the official chronicle as markedly higher than the original watch lists of the Fourth and Seventh Companies attested — a discrepancy of nearly forty warriors, who had either been miscounted out of negligence or, as Vaas increasingly began to suspect, deliberately added to create the impression of a broader, more incontestable attestation than had actually taken place.

"That cannot be chance," Vaas murmured to himself, spreading the documents out before him, marking their connections with red threads on a holographic projection that filled his whole working area. Every single detail, taken alone, was too small to arouse suspicion — a footnote here, an imprecise formulation there. But in sum they drew a picture that fundamentally contradicted the official history.

Before he sought out Castigon, Vaas spent another day going through the scattered chronicles of other Chapters that might have preserved independent testimony about Eskrador — a laborious, largely fruitless search, since few other Chapters had operated near the fighting at that time. A single mention, in a fragmentary White Scars chronicle about later encounters with Alpha Legion cells, stayed with him: a passing note that after the "supposed destruction of their Primarch on Eskrador" the Alpha Legion had fought on with unchanged, if not increased, efficiency — an observation the White Scars chroniclers themselves had evidently not questioned further, but which lent Vaas's growing suspicion a further weight.

He finally sought out an old brother whose very existence constituted a kind of living archive — Dreadnought veteran Castigon, whose mortal body had been so severely wounded over eight thousand years ago in the battle of Calth that only interment in a Dreadnought sarcophagus had been able to save his life. Castigon was too old to remember Eskrador personally — he had not lived through the battle himself — but he had, in the centuries of his service afterwards, spoken with enough veterans to supply Vaas with a further and unusual piece of information.

"There were rumours," said Castigon, his voice distorted by the vox of the massive Dreadnought chassis, but carried nevertheless by an ancient dignity that millennia had not lessened. "Not in the official channels, of course. But among the veterans, in the quiet hours after a campaign, when men say things they would never write into a report. I heard them for the first time over seven thousand years ago, from a brother who had himself served at Eskrador and fell in the field shortly afterwards — he told me that something about that burning was not right, that the men who guarded the pyre behaved strangely, almost relieved, in a way that did not fit the mourning of a won but costly victory."

"Relieved of what?"

"That I have asked myself ever since, Chronicler, without ever finding an answer." Castigon's massive sarcophagus moved slightly, a gesture that in a man of his condition looked almost like a shrug. "I took the story for a legend, like so many that circulate among veterans. But you ask me with a seriousness that tells me you already know more than you admit."

Vaas was silent a moment, his thoughts weighing the implications of what he had just heard. "I know nothing with certainty, Brother Castigon. I know only that the holes in our own history are larger than anybody in ten thousand years has been prepared to admit."

Castigon was silent a long time, his massive sarcophagus motionless in the quiet chamber assigned to him as a resting place, far from the noisy training halls of the active companies. "I have served eight thousand years in this body, Chronicler," he said at last, his mechanical voice pervaded by a weariness no vox modulator could entirely conceal. "I have learned that the stories we tell ourselves about our own victories often say more about what we need to believe than about what actually happened. That does not make them worthless. But neither does it make them infallible."

"What would you advise me, brother?"

"I would advise you to be careful with whom you share these questions, before you are yourself sure which answers you are seeking." Castigon's sarcophagus moved slightly, accompanied by a mechanical creaking that sounded almost like a sigh. "There are truths, Chronicler, that a Chapter can carry, and others that can break it, not by their size but by the way they are spoken. Be sure that you are ready to live with the consequences before you open that door any further than it already stands open."

III. The Captain and the File

He finally carried his gathered findings to Captain Heraclon of the Fourth Company, a man Vaas had known for decades, not as a close friend — Astartes friendships seldom followed the patterns of human closeness — but as an officer whose judgement he placed above that of anybody else in the present Chapter leadership. Heraclon had earned a reputation for unshakeable loyalty both to the truth and to the welfare of his Chapter — a rare combination that made him, as Vaas hoped, the ideal first confidant for a discovery that would put both loyalties to a hard test. He had already once in his own career seen Heraclon defend an uncomfortable tactical truth against the resistance of higher-ranking officers, in a matter that had nothing to do with the present situation, but that served Vaas as reliable proof of the captain's character.

Heraclon listened to Vaas's exposition in his private quarters without interrupting a single time, his expression unmoved throughout the whole presentation, with the disciplined attention of a man who had learned that hasty reactions seldom served the finding of truth.

"You are suggesting," he said at last, when Vaas had finished, "that our Primarch may not have killed the man he believed he was killing."

"I am suggesting that the evidence we have regarded as final for ten thousand years does not, on closer examination, justify that certainty." Vaas chose his words with the care of a man who knew that every sentence he spoke in this room would carry consequences reaching far beyond this one conversation. "I do not say that Alpharius lives. I say that we do not know it with the certainty our whole chronicle claims."

Heraclon stood up, stepped to the narrow window of his quarters, which offered a view over the wide, ordered defences of Macragge — a city that was itself a monument to the principles Guilliman had stood for his whole life: clarity. "Do you know what this insight would mean if it became public, Chronicler? Not only for our historiography. For the Primarch himself. He carries the death of Alpharius as one of his few personal victories from that time — not with pride, that would not suit him, but with a kind of completed peace that at least this one threat was finally neutralised, while so much else from those years remained unfinished."

"I understand the weight, Captain." Vaas stepped a pace closer, his voice growing firmer, although he did not lose the respect he felt for his interlocutor. "But I also think of something else, Captain — of all the brothers who in the last ten thousand years have fallen in the name of that one supposedly final victory, convinced that at least one threat had been banished for good. If that was a lie, however well meant, then we owe every one of them not to preserve that lie any longer merely because the truth is uncomfortable."

"I am not sure that you fully understand it." Heraclon's voice now carried a sharpness Vaas had seldom heard from him. "The Primarch already has burdens enough to carry in the few years since his return — a galaxy he hardly recognises, an Imperium that has changed in his absence in ways that in much contradict his original principles, brother Primarchs who are either dead or lost on paths he had not foreseen. If we now tell him that even this one clear victory may have been an illusion —"

"Then we tell him the truth," Vaas interrupted, with a directness unusual for his office, but which he held to be necessary in that moment. "Or an approximation to it, incomplete as it may be. That is my task, Captain. Not to preserve truths that are comfortable. To preserve truths that are true."

Heraclon turned fully to him, his face marked by an inner conflict Vaas had seldom observed in a man of his rank. "Do you know what disquiets me most, Chronicler? Not the possibility that we discover an uncomfortable truth. It is the possibility that this truth, once spoken, can no longer be taken back — that we, in our striving for accuracy, destroy something our Chapter has needed for ten thousand years in order to understand itself. What happens to a man who places clarity above all things, if we show him that one of the few really clear memories he preserves from that chaotic time may have been an illusion?"

"I do not know," Vaas admitted honestly. "But I believe that a man who places clarity above all things is ultimately strengthened more by an uncomfortable truth than by a comfortable lie, however painful the first moment of recognition may be."

Heraclon was silent a long time, his gaze still on the city outside. "Before we tell anybody anything, we need more than conjectures assembled out of old field reports and veterans' rumours."

He stepped back from the window, his hands clasped behind his back, a posture Vaas had often observed in him when he was thinking through a tactical problem that admitted no easy solution. "I have spoken with our Primarch twice myself since his return," said Heraclon, his voice growing quieter, almost confidential. "Both times I was impressed by his clarity, his ability to penetrate even the most complicated strategic situations with a precision that ten thousand years of absence have not clouded. But I noticed something else too, Chronicler — a tiredness, hidden deep beneath that clarity, worthy of a man who has skipped ten millennia only to find that the galaxy he believed he was saving has suffered a thousand new wounds in his absence."

"You fear that this discovery would be another wound."

"I fear that it might be the one wound he is no longer able to carry." He finally turned to Vaas, his decision visibly taking shape. "We shall continue this investigation, but discreetly, without attracting the attention of the Chapter council before we hold something more concrete in our hands. I shall assemble a small escort. If there is a way to gain more certainty about what actually happened on Eskrador, then we shall find it — before we lay a burden on the shoulders of our Primarch that may in the end prove unnecessary."

IV. The Last Veteran

The trail that finally led them to a concrete next action came not from the archives themselves but from a marginal note Vaas had almost overlooked — a reference to a single surviving veteran of the battle of Eskrador, a man named Sergeant Tyrellian, who after his honourable discharge from active service over nine hundred years before had spent the rest of his life as a Chapter serf on a small agri world at the edge of Ultramar.

Nine hundred years was a long time even for a former Astartes, whose extended lifespan had already been stretched by the hardships of service. They finally found Tyrellian, old and frail but still clear of mind, on a small farmstead he had built for himself in the foothills of a terraformed woodland — a man who had spent the last centuries of his long life in deliberate seclusion, far from the order and ceremony of the Chapter he had once served. The journey to his remote farmstead alone had taken two additional days, over unmade roads scarcely suited to the occasional trade cart, let alone to two Astartes in civilian disguise — a seclusion Vaas understood as a further, quiet indication of the burden the old veteran carried with him.

The farmstead itself was modest but carefully kept, surrounded by fields that Tyrellian, as they later learned, largely worked with his own hands despite his advanced age — an occupation he preferred, as he explained to them, to the idleness that would have left him alone with his own thoughts.

"I have been waiting," said Tyrellian when Vaas and Heraclon, in plain clothing rather than full armour so as to draw no attention to the small farmstead, knocked at his door. His eyes, though clouded by age, still carried the sharp attention of a man who had learned in his youth to recognise any threat at once. "I knew that somebody would come at some point to ask questions about Eskrador. I had only not expected it to take so long."

"You expected us?" asked Heraclon, surprised by the old man's directness.

"I have feared it since the day of the battle itself." Tyrellian led them into his modest house, his movements slow but not without a certain remaining dignity. "Sit down. What I have to say will take a while, and I am no longer as quick in speaking as I once was."

He told them, over the following two hours, a version of the battle of Eskrador that had never been recorded in any official chronicle. He had been part of the elite unit Guilliman had personally led in the final, desperate assault on the headquarters of the Alpha Legion. He had seen the duel between the two Primarchs with his own eyes, from a distance near enough to catch details that later chroniclers, who had never been there themselves, could not possibly have known.

He described the battle itself with the vivid, painful precision of a man who had never quite let go of the decisive moments of his life — the deafening noise of the assault, the surprising ease with which the elite unit broke through the outer defensive lines of the Alpha Legion, an advance that in hindsight, as Tyrellian himself admitted, had gone suspiciously smoothly for an enemy notorious for his unpredictable defensive tactics.

"It was a good duel, if one can call such a thing good," said Tyrellian, his voice growing quieter as he remembered the details. "But it felt wrong, even in the moment in which I watched it. Alpharius fought well, but not with the full strength the legends ascribed to him. It was as though he were testing rather than fighting — as though he were studying our Primarch more than fighting against him to preserve his life."

"And when he died?" asked Vaas.

"He said something, in the last moments before our Primarch's blade ran him through." Tyrellian's hands, wrinkled and age-spotted, trembled slightly as he remembered the words. "I was near enough to hear it, though I doubt anybody else did, amid the noise of the battle still raging around us. He said: 'Good. This is good. Now I am free, and my brother can complete the work I have begun.'"

The words hung in the quiet room, while Vaas and Heraclon exchanged a look that carried a wordless confirmation of their worst fears.

"'My brother'," Vaas repeated slowly. "He was speaking of Omegon."

"I do not know of whom he was speaking, Chronicler. I know only what I heard, and that those words have not let go of me since, in nine hundred years of quiet reflection." Tyrellian's hands trembled more strongly now, his voice barely more than a whisper. "Do you know what the worst of it is? For nine hundred years I have spoken of it to nobody — not out of loyalty to silence, but because I feared they would declare me mad, or worse, accuse me of heresy for daring to doubt the official history of our greatest victory. I have carried those words with me like a stone that grew heavier with every century, until I finally withdrew here, far away from anybody who might have asked me why a veteran of Eskrador never wanted to speak about his greatest battle."

"Why are you telling us now?" asked Vaas quietly.

"Because you came to ask, rather than to force an answer on me." The old man looked back and forth between the two Ultramarines, his clouded eyes marked by a relief that had been deferred for nine centuries. "And because I am too old to carry this burden much longer without its dying with me, unspoken, as it almost did."

He was silent a moment, his hands closed around a cup of long-cold tea he had prepared at the beginning of their conversation but never touched. "Do you know what tormented me most all those years? Not the uncertainty itself. But the thought that by keeping silent I became part of the same lie I had begun to fear — that my silence did as much damage as any deliberate deception, because it allowed a truth to remain unexamined that might have warned thousands more men, had it come to light earlier."

Tyrellian looked back and forth between the two Ultramarines, his old eyes marked by a burden he had evidently carried for a very long time. "I never found the courage to report it to a superior. What should I have said? That I believed our Primarch had possibly killed the wrong man, or that he killed the right one, but that this death was part of a greater plan none of us understood? Both sounded like the madness of an old soldier who had spent too long on the battlefield."

V. The Missing Archives

The return flight from Tyrellian's remote farmstead passed in thoughtful silence, both men wrestling with the implications of what they had just heard. Vaas found himself returning again and again to the old man's words — now I am free, and my brother can complete the work I have begun — and tried to weigh every possible interpretation that statement might allow, without a single one of them entirely easing his growing disquiet.

Back on Macragge, with Tyrellian's testimony as a new and weighty confirmation of their growing doubts, Vaas turned to the last remaining source he had not yet fully exhausted — the original physical archives, not the digitised, easily accessible copies, but the original data cores and parchments stored in the deepest, least visited levels of the Index Athanaeum.

What he found there, or rather what he did not find, disquieted him even more than everything before. He spent the greater part of a full day alone in that chamber, forgetting his meals, delegating his other duties to a younger colleague, so complete was his concentration on the task before him.

Vaas searched the dusty, seldom visited shelves with a meticulousness unusual even for his office, examining every data core singly, comparing every catalogue entry with the physical holdings, in the hope that somewhere in that vast, millennia-old labyrinth of knowledge a single overlooked fragment would supply the missing answers.

The complete Apothecary reports on the genetic verification of the body — those from which Sennian's cautiously worded summary derived — were entirely missing from the physical archive. Not damaged, not lost through the usual accidents of ten thousand years of storage, but, as the catalogue entries themselves indicated, formally removed, at a point in time that could be dated precisely to a few decades after the battle itself.

"Somebody removed these records deliberately," said Vaas to Heraclon, as they looked together at the empty place on the archive shelf where the missing documents should have lain. "And whoever it was had the authority to do it without its ever being noticed in the following millennia."

"Or it was noticed, and those who noticed it chose to keep silent." Heraclon's voice carried a new, deeper disquiet. "Chronicler, I must ask you something that has not let go of me since our conversation with Tyrellian: how sure can we be that this removal was not itself the work of the Alpha Legion? Their infiltration capabilities are legendary, even within loyalist Chapters. If they have managed to erase their traces from our own archives, what guarantee do we have that they are not still operating among us today, in some form?"

The thought settled in Vaas like a cold stone. He thought of every brother with whom he had worked in the Index Athanaeum in the last forty years, of every chronicler, every archivist, every visitor who had had access to the innermost chambers of the library — and recognised with growing unease that he, like everybody else in his Chapter, would never really have had a way of distinguishing a skilfully disguised infiltrator from a true brother, if the Alpha Legion did in fact possess the means the legends ascribed to it.

"We cannot rule out that possibility," Vaas said at last, his voice burdened with the weight of this new realisation. "But neither can we prove it by regarding every brother in our Chapter with mistrust. That would be exactly the kind of paranoia the Alpha Legion, if it really is operating here, would use to its own advantage — to bring us to tear ourselves apart out of mere suspicion."

"Then what do you propose we do?" asked Heraclon, his voice tense with the burden of a responsibility that went far beyond his usual command.

"We proceed methodically, as our office requires of us." Vaas began to order the scattered data cores systematically, his hands working with practised precision despite the disquiet within him. "We document every gap, every discrepancy, without drawing hasty conclusions about its cause. If the Alpha Legion is in fact responsible for this removal, that will emerge sooner or later from the pattern itself — from the precision with which the deletion was carried out, from the specific documents affected, compared with those left untouched."

"And if we establish that it was indeed their work?"

"Then at least we know what we must arm ourselves against." Vaas paused, a data core in his hand whose catalogue entry pointed to another missing report. "I prefer an uncomfortable truth to a comfortable ignorance, Captain. That has always been the core of my office, even if I am only now beginning to understand how heavy that preference can actually be to carry."

The question hung heavy in the air of the quiet archive chamber, and Vaas felt a cold, unwelcome doubt settle in him — a doubt that went beyond the original historical question, to something far more disquieting: that the Ultramarines themselves, for ten thousand years, might never have been entirely safe from the Legion they had believed finally defeated.

"There is a way to check that," Vaas said at last, his voice quieter, as though he feared they might be overheard even in that secluded chamber. "If the verification reports were removed but the actual site of the burning still exists, modern forensic methods might still be able to find usable traces. These are techniques that were simply not available ten thousand years ago. Genetic material that can endure in traces even in burnt ash across millennia, if one knows what to look for."

"You are proposing that we send an expedition to Eskrador."

"I am proposing that we return to where this story began and see for ourselves what ten thousand years of silence may have concealed." Vaas looked Heraclon directly in the eye. "I know what that means, Captain. It means setting foot on a world that has counted as a closed battlefield for ten millennia, but which, if my growing fears are correct, may never have been entirely left by those who once fought there."

VI. Return to Eskrador

The journey to Eskrador took nine days, aboard a small unremarkable reconnaissance ship that Heraclon had personally requisitioned, under the official pretext of a routine historical survey mission — a cover thin enough not to hold up under closer examination, but sufficient to raise no immediate questions in the Chapter council.

Vaas spent a large part of the journey studying every available detail of the geographical location of the original battle, with the help of a Librarian who travelled with them — Epistolary Delvain, a man with exceptional forensic and psychic abilities, whose presence Heraclon held to be indispensable should they in fact find usable traces at the site of the original burning.

Delvain was an unusual Librarian, even by the standards of a Chapter that treated its psychically gifted with particular care and suspicion at once — a man whose abilities concentrated less on offensive fighting power, as was the case with many of his brothers, than on a rare sensitivity for what he himself called "the echoes of the past": the ability to read traces of past events in the structure of reality itself, long after every physical memory had faded. In the weeks of their collaboration Vaas had learned both to admire and to fear that gift, for it allowed Delvain to perceive things that no chronicler, however thorough, could ever have derived from mere documents. He thought of an incident from the first weeks of their collaboration, when Delvain, during a routine review of an apparently insignificant administrative report, had perceived a subtle emotional dissonance in the words of a long-dead scribe — a dissonance that later proved to be evidence of an entirely different conspiracy within the administration of a border world, recorded in no official document. It had been that experience that convinced Heraclon to request the Librarian for this particular mission, despite the additional complexity his presence brought to the secrecy of their investigation.

Vaas watched Delvain's careful preparations with growing tension, his thoughts wavering between hope of final clarity and the growing fear that at the end of this journey they would stand there with even more questions than they had brought with them. He watched the Librarian spend hour after hour sharpening his psychic abilities through meditation, calibrating his concentration to a precision that would be necessary for the coming task — a preparation that reminded Vaas of the decades of discipline his own office as chronicler demanded of him, if exercised in an entirely different way. "If there is in fact still anything to be found there, after ten thousand years," said Delvain, while he prepared his own instruments, "it will hardly be accessible by ordinary forensic means. But a genetic echo, particularly from a being of primarchic physiology, can sometimes burn itself into the surrounding matter in a way that outlasts even millennia — no longer as physical substance, but as a kind of psychic imprint that a practised Librarian can read, if the conditions are right."

"And if the conditions are not right?" asked Vaas, no longer concealing his own uncertainty about the undertaking.

"Then we shall return empty-handed, and this whole journey will prove a waste." Delvain's voice carried no illusion about the uncertainty of their undertaking. "But I believe, Chronicler, that you and I are both aware that we are hoping for more here than mere forensic confirmation. We are hoping for a truth that allows us either to return to our Primarch with a clear conscience and tell him that his memory has deceived him, or with the heavier burden of telling him that an enemy he held to be dead may still be operating somewhere in the galaxy."

During the last days of their journey through the warp, Vaas found himself again and again in conversations with Heraclon that went far beyond the immediate mission — conversations about the purpose of the Chapter itself, about the question of what it meant to serve a Primarch who, unlike in the ten thousand years before, actually lived, spoke, judged, was fallible in a way pure legend had never permitted. "For ten thousand years we have worshipped an absent god," Heraclon said once, in a rare moment of openness, while they studied the star charts of their coming destination together. "Now we have a living brother who can make mistakes, who can be deceived, who can doubt. I am not sure that our whole Chapter has yet fully understood what that means."

They reached Eskrador on the tenth day, and Vaas, when he first looked at the surface of the world through the view-port of their landing shuttle, understood at once why that battle cast such a shadow over the history of his Chapter even after ten thousand years. The planet still carried, in its geological structure itself, the scars of the orbital bombardment with which Guilliman had ended the battle — wide, vitrified craters whose rims even after ten millennia still bore an uncanny, unnatural smoothness, as though the sheer violence of the destruction had frozen time itself in that one moment.

"Where exactly did the burning take place?" asked Heraclon as they approached the surface.

"According to the original field reports, here." Vaas pointed at a coordinate at the edge of one of the largest craters, a place described in the official chronicle as "the Hydra Nest" — the former headquarters of the Alpha Legion on this planet, now nothing more than a wide vitrified expanse, at whose centre, if Tyrellian's memory was correct, a pyre had once burned that made a whole galaxy believe its most dangerous enemy had finally been destroyed.

VII. The Ash of the Pyre

The landing passed without incident, but from the first moment they set foot on the ground of Eskrador, Vaas felt a disquiet that could not be explained by the physical desolation of the surroundings alone. The air itself carried a peculiar metallic smell, a remnant, as Delvain supposed, of the massive orbital bombardment that even after ten thousand years had altered the chemical composition of the upper atmospheric layers. Above them hung a permanent thin veil of haze that dipped the light of the distant sun into a pale, almost uncanny grey, as though the planet itself refused ever to return fully to the light.

"Something is watching us," said Delvain quietly, scarcely ten minutes after their landing, his face tense with the concentration of his psychic senses. "I cannot localise it exactly, but the presence is real, not imagined. We are not alone here, Captain."

Heraclon reacted at once, ordering his escort — four additional Ultramarines brothers, chosen for their discretion as much as for their fighting abilities — into a defensive formation, while they cautiously approached the marked location of the former Hydra Nest.

The four escort brothers, whose names Vaas had barely registered in passing during the days of preparation — Brother Cassian, Brother Ordell, Brother Thessan and the young Aulen, for whom this was the first real field mission — moved with the disciplined precision that every Ultramarines training instilled, their weapons ready but not openly aggressive, as they crossed the jagged, crater-strewn landscape. Vaas noticed how even these experienced warriors showed an underlying tension that went beyond ordinary field caution — as though the world itself, with its unnatural stillness and its permanent twilight, instilled a deep-rooted disquiet in everybody who set foot on it.

They passed the remains of what must once have been outer defensive ramparts, now scarcely more than melted, irregular elevations in the vitrified ground, whose original form could only have been reconstructed by careful geological analysis. Delvain stopped several times, his psychic senses evidently registering faint but disquieting echoes from the past that he was not always prepared to comment on aloud.

The place itself, when they reached it, was barely recognisable as what must once have been a fortified headquarters — only a wide vitrified hollow, covered with the grey granular dust of ten thousand years of weathering, broken by isolated, almost completely eroded fragments of structure that protruded from the ground like the ribs of a long-decayed animal.

They searched the remaining fragments of structure for a full hour without concrete results, before Delvain finally stopped, his movements slowing as he approached a particular point in the middle of the vitrified hollow, as though an invisible force were drawing him there.

"Here," said Delvain, kneeling at a particular spot, his hand gliding over the dust, with a concentration that contorted his whole face. "Here was the pyre. I can still feel an echo — faint, weathered, but present. A kind of scar in the psychic fabric of this place, like a wound that never entirely healed."

"Primarchic?" asked Vaas.

"I believe so. But —" Delvain hesitated, his concentration deepening. "There is something strange about this imprint, Chronicler. It does not feel like the echo of a complete death. It feels like —" He searched for the right words, his practised precision for a moment overwhelmed by the strangeness of what he perceived. "Like the echo of a departure. As though something — somebody — had gone away from this place, not extinguished by death, but deliberately left, with an intention I cannot fully decipher."

Vaas knelt beside Delvain, his hand gliding carefully over the same dust, although he knew that he himself possessed none of the psychic abilities that allowed his companion such perceptions. Nevertheless he felt, in a way he could not fully explain to himself, a weight in that place, a gravity of meaning that went beyond mere imagination — as though the history that this place silently preserved were looking directly at him and waiting for an answer he did not yet know how to give.

Before anybody could react to this disquieting revelation, a sharp metallic sound broke the silence around them — the unmistakable noise of an activated force field generator, followed by a voice that seemed to come out of the dust itself, amplified by a helm-vox whose timbre filled Vaas's whole body with an instinctive, deep-rooted alarm.

"You are digging in a grave that does not belong to you," said the voice, calm, almost amused, while out of the surrounding dust and the eroded fragments of structure several figures rose in camouflage-like, barely perceptible armour, their weapons already levelled at the small group of Ultramarines. "That is a discourtesy we have not had to tolerate for ten thousand years. But perhaps it is time you finally received an answer that has been deferred too long."

VIII. The Ambush

Heraclon reacted with the speed of a man trained for exactly such moments, his bolt pistol already drawn, while at the same time he transmitted a sharp non-verbal order to his escort to withdraw into a more defensive formation.

"Alpha Legion," he said, his voice hard but controlled. "After ten thousand years still here, still guarding this grave."

Vaas instinctively counted the visible figures that had risen out of the camouflage — seven, perhaps eight, although he knew that the actual number might be far higher, hidden in positions even his trained senses did not detect. It was a frightening demonstration of what it meant to meet a Legion whose whole conduct of war rested on the principle of never being fully visible until the moment was chosen in which visibility itself became a weapon.

"Not the grave, Captain." The figure that had spoken first stepped forward, his camouflage dissolving into fuller visibility to reveal armour whose hydra-headed symbol was unmistakable even after millennia, if weathered by countless unknown campaigns. "The truth. And I believe you are finally ready to hear it, or you would not have come here with a Librarian who is looking for exactly what we have kept hidden for ten thousand years."

"How many of you are there?" asked Delvain, his psychic senses feeling out the surrounding darkness.

"Enough to steer this conversation in whatever direction we choose." The voice carried an undertone that contained both a threat and, strangely, a kind of invitation. "But we are not here to kill you, Ultramarines. Were we, you would already be dead, in the moment your ship set foot on this world. We are here because your curiosity, uncomfortable as it is for us, is finally asking a question that should have been asked ten thousand years ago."

Heraclon studied the surrounding figures with the precision of a man already automatically registering their relative positions, their cover, every possible line of escape, even amid the uncertainty of the moment. "You did not kill us when we landed, although you evidently could have," he said slowly. "Why this one concession, after ten thousand years of perfect secrecy?"

"Because secrecy has served its purpose as long as it was needed, Captain. But every strategy has its time, and I believe our time of complete concealment is approaching its natural end, at least as far as Eskrador is concerned." The voice carried a certainty that betrayed neither arrogance nor desperation, only a quiet, millennia-old calculation.

Vaas stepped forward, despite Heraclon's immediate, tense gesture to hold him back. "Who are you?"

The figure laughed, a sound distorted by the helm-vox but nevertheless unmistakably carried by genuine amusement. "A question everybody asks who meets us, Chronicler. The answer is always the same, and it has always been the same, for ten thousand years." He drew himself fully up, his build, Vaas noticed with growing disquiet, closer to that of a Primarch than to that of an ordinary legionary, though subtler, less monumental than the legends about the sons of the Emperor described. Around him, partly visible, partly still hidden in the shadows of the eroded ruins, Vaas counted at least seven further figures, whose weapons, though lowered, were held with a casual readiness that left no doubt how quickly the situation could change should one of the Ultramarines make an ill-considered movement.

"I am Alpharius."

One of the Ultramarines escort brothers, a young warrior named Aulen who had taken his full vows only three years before, reacted with the impulsive bravery of a man who had not yet fully grasped the true danger of the situation, and charged the nearest Alpha Legion figure with his chainsword raised. He was disarmed within two seconds, brought to the ground and fixed with a blade at his throat before he had been able to strike a single blow.

"Let him go," Heraclon ordered sharply, his own weapon still raised, although he already recognised how hopeless any further resistance was.

The fight that followed was short and surgically precise, a demonstrative but not lethal display of power by the Alpha Legion warriors, who disarmed and surrounded the Ultramarines escort within seconds without striking a single lethal blow.

"You could have killed us before we were even able to react," said Heraclon, as he faced the leader of the Alpha Legion group, disarmed but unhurt.

The youngest of the escort brothers, Aulen, whose weapon had been wrested from him just as effortlessly, stood with lowered head, his cheeks reddened under his helm with shame at the ease of his own defeat. Vaas saw Heraclon cast him a short, encouraging glance — a silent acknowledgement that the lesson, humiliating as it was, carried no disgrace in the face of an opponent of such superiority. He looked at Aulen, who was picking himself up again, pale but unhurt, his eyes marked by the recognition of his own inferiority, a lesson that, Vaas supposed, he would not forget for the rest of his life.

"We could have." The legionary who called himself Alpharius lowered his own weapon, a gesture whose casualness seemed almost insulting given the obvious superiority they had just demonstrated. "But the dead cannot answer questions, and I believe you have brought a question with you that deserves an answer — after ten thousand years of a silence that seems too long even to me."

IX. The Witness's Truth

They found themselves at last in an improvised but surprisingly orderly underground chamber, deep beneath the vitrified surface of the former Hydra Nest, led into a room by warriors whose existence had remained for ten thousand years a secret no Imperial investigation had ever uncovered. The chamber itself was sparely but functionally furnished — communications devices whose technology seemed to Vaas's trained eye foreign and yet advanced, shelves of data cores whose contents he could only guess at, and, on one wall, a large hand-drawn map of the whole Ultramar region, covered with markings whose meaning was not apparent to him, but which bore witness to millennia of meticulous surveillance.

"So you have found what we kept hidden for ten thousand years," said the legionary who called himself Alpharius, as he sat down before an improvised map that depicted the whole battle of Eskrador in a depth of detail no Imperial archive had ever achieved. "I shall not insult you with false modesty, Chronicler. You are right to doubt the official history. But the truth you are seeking is more complicated than even your worst fears suggest."

"What actually happened on Eskrador?" asked Vaas directly.

"Guilliman killed my brother — or me, depending on which version of the story you wish to believe, for even after ten thousand years I am not prepared to resolve that one last uncertainty for good." The legionary spoke with an openness Vaas had not expected, given the millennia of secrecy surrounding this truth. "The duel was real. The death was real. But the person who died already knew that he would die, long before the blade ran him through — and accepted that death not as a defeat but as a necessary step in a plan that reached far beyond the limits of that one battle."

"A plan of the Cabal," said Delvain, his voice quiet, as though he were speaking an old, almost forgotten legend.

The legionary looked at him with something that seemed like real surprise. "You know that name, Librarian. Few outside the innermost circle of our own order do." He studied Delvain a moment longer, with an attention that seemed to go beyond mere curiosity. "Where do you know that name from, if I may ask? It is not recorded in any publicly accessible chronicle I know of."

"Fragments," said Delvain cautiously. "Scattered indications in old interrogation reports I studied in the course of my training. I never understood the full significance, until today."

"Then you are more thorough than most of your rank, Librarian." The legionary turned back to Vaas. He nodded slowly. "Yes. Part of what was revealed to us through that xenos alliance before the Heresy required us to make sacrifices that none of our brothers in other Chapters would ever fully understand — sacrifices that sometimes meant staging one's own death in order to gain a freedom no living Primarch could ever have claimed, under the constant observation of friend and foe alike."

"And you have known for ten thousand years that your doctrine, your whole public identity as followers of Chaos, was a lie built on a foundation none of you was ever permitted to speak fully aloud?" asked Heraclon, his voice a mixture of disbelief and reluctant respect.

"Not entirely a lie, Captain. Some of our brothers have in fact given themselves to the Ruinous Powers, in genuine belief, in genuine corruption, as every other Legion did that followed the Warmaster. We are no exception to that truth, however much we use it for our own purposes. But a significant core of our Legion — a core whose exact size even I do not know with certainty — has always treated that allegiance as a tool, not as a creed."

"You are saying that one of you, Alpharius or Omegon, staged his own death in order to escape Imperial attention," said Heraclon, assembling the implications.

"I am saying that the truth is more complicated than pure staging." The legionary stood up, his movements with a deliberate dignity that Vaas, despite everything he had heard about the Legion, found respectable. "My brother did in fact die, on that day, on Eskrador, at the hand of your Primarch. That is no lie. What your chroniclers never understood is that his death was a decision he made himself, long before the battle began — a last necessary sacrifice to allow the rest of the Legion to operate without the burden of a living, huntable Primarch, while the surviving twin continued the real, long-term work we had begun before the Heresy."

"What work?" asked Vaas.

"A work that neither your Primarch nor most of our own brothers would ever fully understand, even if we could explain it in every detail." The legionary stepped to the hand-drawn map on the wall, his hand gliding over the countless markings Vaas had noticed earlier but not deciphered. "Every one of these markings represents an intervention, a quiet shift, a catastrophe that was prevented, or sometimes, hard as it may be to accept, a catastrophe we deliberately allowed, because preventing it would have brought on a still greater misfortune. For ten thousand years we have worked, in concealment, without thanks, without recognition, often under the cloak of the same traitor designation your chronicles ascribe to us, because that disguise gave us the freedom to act where loyal servants of the Imperium would have been paralysed by bureaucracy, dogma and fear."

"That sounds like a comfortable justification for ten thousand years of Chaos allegiance," said Heraclon sceptically.

"It is no justification, Captain. It is an explanation you may take or discard as you please." The legionary turned back to them, his voice unchanged and calm. "I do not expect you to trust us. Trust was never the aim of our existence. Only survival — that of your species, not necessarily that of our own honour."

"The work of keeping this galaxy alive as long as possible, regardless of the cost to our own honour, our own peace of mind." The legionary looked directly at Vaas, his eyes not visible beneath the helm, but his voice carried a weight that seemed to admit no deception. "You will not fully understand this answer, not today, perhaps never. But know this when you return to your Primarch: the man he killed on Eskrador did not die as an enemy who was defeated. He died as a brother who made one last necessary decision, for a purpose greater than his own survival."

X. The Chronicler's Decision

Delvain, who until now had largely kept silent, his psychic senses still feeling out the chamber and its inhabitants, finally put a question that neither Vaas nor Heraclon had dared to put. "If you are really telling the truth, if your Legion has in fact been working in concealment for ten thousand years for the survival of mankind — why this openness now, after such a long time? What has changed that you are prepared to reveal even this fraction of your secrets?"

The legionary turned to him, and for a moment Vaas believed he recognised in his bearing something that went beyond the control previously demonstrated — a kind of cautious, calculated hope. "Because your Primarch lives, Librarian. For ten thousand years we have worked for a future we never fully understood ourselves, guided by a prophecy that revealed to us only fragments. Now that one of the mightiest sons of the Emperor has returned to lead this galaxy, the equation changes. Perhaps it is time that at least a part of the truth came to light — not because we want it, but because circumstances require it."

Delvain, who until now had mainly used his psychic senses to test the truthfulness of the legionary's statements, finally spoke, his voice carried by a cautious but genuine conviction. "I cannot say with absolute certainty that every word we have heard is true. But I can say that I find no signs of deliberate deception in the emotional undertones of his words — which, in a member of this Legion, is in itself remarkable."

"That does not reassure me as much as you perhaps intend, Librarian," said Heraclon drily. "A Legion famous for its ability to deceive even psychic detection could stage exactly what you are now interpreting as a sign of sincerity."

"That is true," Delvain admitted. "But at some point, Captain, we must make a decision whether we are capable of trusting this Legion at all, to any degree, or whether we regard every interaction with it as fundamentally impossible to verify. That second attitude would mean that we can never learn anything about them, no matter how many further encounters we seek."

Vaas, who had followed the exchange with growing inner division, finally found his own voice again. "I should like to put one last question before we leave this chamber," he said, turning directly to the legionary. "If your brother — or you yourself, depending on which version is true — died on Eskrador in order to buy freedom for the rest of the Legion, what exactly did that freedom make possible that would not also have been possible under the burden of a living, known Primarch?"

The legionary regarded Vaas a long time, with an attention that seemed to acknowledge the significance of the question. "A good question, Chronicler, perhaps the best you have put so far." He was silent a moment, as though weighing how much he could reveal without going too far. "A living, known Primarch is a target — for assassins, for rival Chaos powers, for anybody who believes that removing him would give him a strategic advantage. A dead Primarch whose death was publicly witnessed and accepted is invisible. He can do things, visit places, forge alliances that would have remained closed for ever to a living, hunted target."

The legionary offered no further details, however much Vaas and Heraclon insisted in the following hours of their conversation — a reserve that persisted even amid his surprising openness about the fundamental truth of the battle.

"I have told you more than anybody outside our own order has learned in ten thousand years," he said at last. The sun of Eskrador, cold and distant like every detail of this abandoned world, was approaching the horizon. "To say more would mean revealing secrets that are not mine alone but belong to a Legion whose whole existence rests on the premise that its true intentions may never become fully known — not out of malice, but because the knowledge itself, in the wrong hands, could do more damage than any lie we have maintained so far."

"What shall we tell our Primarch?" asked Heraclon, his voice heavy with the burden of the decision before them.

"That," said the legionary, "is a question I cannot answer for you, and should not answer. That is the burden of your own office, Chronicler, Captain — not mine." He turned to go, his form already dissolving into the shadows of the surrounding ruins, with the same soundless precision with which he had appeared. "But I will tell you this before I go: a truth one is not prepared to carry in full is sometimes more dangerous than a lie one deliberately chooses to live. Think on that before you decide what you report to your Primarch."

He vanished, together with his whole escort, with a speed and soundlessness that even Delvain's trained psychic senses could not fully follow, and left the three Ultramarines alone in the growing darkness of a planet whose secrets had proved far more complicated than any of them had expected at the beginning of this journey.

"Do you believe him?" Heraclon finally asked, as they returned to their waiting shuttle.

"I believe he told the truth as he understands it," said Vaas slowly. "I do not believe he gave us the whole truth — only enough to satisfy our immediate curiosity without endangering the deeper secrets of his Legion. That is, as I now understand, the only kind of truth the Alpha Legion ever gives."

"And what do we report to the Primarch?"

"We could also decide to report nothing at all," said Heraclon, speaking the possibility cautiously, as though he were still testing it himself while he formulated it. "We could treat this whole journey as what it already is in the eyes of the Chapter council anyway — a private, unofficial investigation whose results we keep to ourselves until we have complete certainty, not merely fragments of a possibly incomplete truth."

"That would be the more cautious choice," Vaas agreed. "But I do not believe it is the right one. Not because I am sure what the right choice is — but because I believe that the decision what should happen with this truth should not lie with the two of us alone. We have a responsibility to pass it on, to those who have the authority to judge it finally, even if we ourselves do not know what that authority will do with it."

Vaas was silent a long time, his thoughts torn between his duty as a chronicler — committed to the truth, regardless of its consequences — and a new, unexpected compassion for the burden that truth would lay on a man who already carried more than anybody could fairly be asked to carry.

"The truth," he said at last. "But not the complete version, which we do not ourselves possess. We shall tell him what we know, what we suspect, and what we do not know — and leave him the decision what he wishes to do with that uncertainty. That is all I can offer as a chronicler, Captain. Not certainty. Only the most honest approximation to it that I could find."

XI. What Guilliman Does Not Know

They returned to Macragge nine days later. The report Vaas finally composed was careful and balanced: it did not conceal the speculations, but neither did it present them as final facts. It was transmitted not directly to the Primarch himself but, on Heraclon's cautious advice, first to the Chief Chronicler, whose centuries of experience in handling sensitive historical findings offered an additional level of examination before a decision was made about final disclosure.

"The Primarch will be informed when the Chief Chronicler holds it appropriate," said Heraclon, as they went through the report together one last time before it was transmitted. "That is no cowardice, Vaas. That is the acknowledgement that some truths must be handled with greater care than a single discovery can provide."

"I understand that," said Vaas, although a part of him — the part that had learned over forty years that truth deserved no delay — still resisted that cautious, institutional reserve.

In the weeks that followed, Vaas heard nothing official about the fate of his report — whether it had actually reached the Primarch, whether Guilliman learned of the possibility that his old enemy had, in whatever form, outlasted the ten thousand years since Eskrador. He observed, in that time of uncertainty, his own superiors with a new and watchful attention — searching for signs that his report had been taken seriously, for subtle changes in the behaviour of the Chief Chronicler, who continued to show him the same professional, impenetrable courtesy he had shown before the report was transmitted. Once, in a casual conversation in a corridor, he believed he caught a brief, searching look from the old chronicler that lasted longer than an ordinary meeting would have justified — but the moment passed so quickly that Vaas could not be sure whether he was not simply projecting his own tension into a gesture that meant nothing at all. He returned to his ordinary duties in the Index Athanaeum, quietly carrying with him the weight of what he had discovered, while he went on tending chronicles that now, as he knew, would never fully contain the truth he himself knew. It was a strange, isolating experience, to tend the same chronicles day after day, to teach the same young aspirants who still took in the old, incomplete version of the history of Eskrador as incontrovertible truth, while he himself knew how fragile that foundation actually was. He sometimes wondered, in the quiet hours between his official duties, how many other chroniclers before him had harboured similar doubts but never found the courage to pursue them — and how many further uncomfortable truths, hidden in the depths of the Index Athanaeum, were still waiting for a similarly stubborn successor.

It was Delvain who finally sought him out three months after their return with a new and unusual message — an encrypted transmission attributed to the legionary they had met on Eskrador, addressed directly to Vaas, in a form only a Librarian with Delvain's abilities could have decrypted.

"He has left us another trail," said Delvain, his voice marked by a mixture of caution and fascination. "Coordinates, to a system I do not know, accompanied by a single message: 'If you wish to search further, if you are ready to understand what we are really trying to protect, then search there. But be warned — what you find will not give you the certainty you seek. Only more questions, worthier of being asked.'"

Vaas received the coordinates with a growing, restless resolve, wondering whether this new trail would bring him closer to a final truth about the Alpha Legion — or whether he would, as once before, only discover another layer of a deception that went deeper than anybody outside the Legion itself could ever fully understand.

He thought of Tyrellian, alone on his small farmstead, freed at last from nine hundred years of silent doubt; of Castigon, whose centuries-old warning had not let go of him; of Heraclon, wrestling somewhere on Macragge with the same uncertainty Vaas himself could no longer shake off. He thought above all of the legionary on Eskrador, of his last words, which had run through his thoughts ever since like an echo — that a truth one was not prepared to carry in full could be more dangerous than a deliberately chosen lie.

Delvain nodded slowly, his agreement carried by a quiet, shared resolve, before he put the actual question. "Shall we go?"

"I have family on Macragge whom I have not visited for months," said Delvain after a moment of reflection, his voice light but not without real weight. "A younger brother who works in agriculture, far from any Astartes affair. Sometimes I envy him the simplicity of his life, particularly in moments like this, when I stand before the choice of pressing still deeper into a secret that may never leave me in peace again."

"But you will go all the same," said Vaas.

"I will go all the same. Because my brother's simplicity is one I have never allowed myself since I discovered my gift. Some of us are destined to search in the shadows while others may live in the light. I made my peace with that destiny a long time ago."

Vaas looked at the coordinates, thought of the legionary who had called himself Alpharius, of Tyrellian's nine hundred years of silent doubt, of the burden Guilliman might now be carrying somewhere on Macragge, without Vaas knowing it for certain.

"Yes," he said at last. "If we stop now, this truth will remain incomplete for ever — and I no longer believe that an incomplete truth is better than none at all. We shall go, Delvain. And this time we shall not only ask questions. We shall demand answers, however uncomfortable they may be."

END OF PART I

Afterword: This novella deliberately leaves open whether the legionary Vaas and Heraclon met on Eskrador was in fact Omegon, an ordinary legionary following the doctrine "I am Alpharius", or something still more complicated. Equally unresolved is whether Guilliman ever learned of the doubts of his own chronicler, and how, if he did, he dealt with that knowledge. That is intentional: the Alpha Legion, more than any other faction of the Warhammer 40,000 universe, exists precisely through what is never fully resolved. Part II, "Hydra Dominatus", follows Chronicler Vaas on a journey that will lead him directly into the heart of that ancient, unresolvable deception.
