History
The first members served among the Unnumbered Sons of Indomitus Crusade Fleet Primus and descended from Corax. When they razed the city of Olda with great efficiency in the early years of the crusade, Guilliman formed the survivors into the Void Sabres. The Chapter was entered into the Ultima Founding at a ceremony he oversaw in person.
Notes
Guilliman assigned Olda as the Chapter's homeworld and charged it with protecting the system and surrounding sectors. The officers' oaths were written into Guilliman's personal copy of the Index Astartes; the Fortress-Monastery was only to be built afterwards.
