Jonah Orion

Jonah Orion is Chief Librarian of the Blood Ravens, the psyker who took Isador's scarred office and then had to fight a Chapter Master who had been a Librarian first. He walked the Aurelian Crusades beside Angelos, survived Eldar, Tyranids, and the Black Legion, and kept the warp from eating the strike force one ritual at a time.

When Kyras declared Angelos renegade, Jonah went with the condemned captain rather than the throne. Retribution made that choice into a war. He lived through Typhon's Exterminatus window and the last fight on Cyrene's ghost.

The Blood Ravens needed a Librarian who would not repeat Tartarus. Jonah's answer has been loyalty to Angelos and suspicion of every convenient relic. Subsector Aurelia is full of those. He is still employed.
