The Angels Revenant is a Codex Astartes-compliant Loyalist Space Marine Chapter and a Successor Chapter of the Ultramarines. This Chapter's origins can be traced to the 8th Founding which allegedly occurred during the mid-34th Millennium, undertaken amid the dark times of the Nova Terra Interregnum, when the Imperium of Man had been split into twin interstellar empires. Ultimately, the Angels Revenant met their fate with the rise of the Necron Maynarkh Dynasty within the Orpheus Sector of the Segmentum Tempestus in 991.M41. It is believed that no more than a few hundred Angels Revenant survived the Necron assault upon their Chapter homeworld. The only survivors were those members of the Chapter who were far from the Orephus Sector on Crusade.
