History
The Inceptors fought in the Macharian Crusade but in the Macharian Heresy clashed with their former allies, the Doom Warriors, over a point of honour. In the Euxcine System they waged a long conflict under set rules and refused to stop. The Minotaurs intervened and nearly wiped them out; fewer than a hundred Marines surrendered.
Notes
The Minotaurs captured relics of the Chapter, including its Great Crusade-era flagship. The Minotaurs have since been denounced across Ultramar, and other Ultramarines successors have sworn vengeance on them.
