Overview

Jonah Orion is the Chief Librarian of the Blood Ravens Chapter, a powerful psyker who served under Gabriel Angelos since the Tartarus campaign. As the sole survivor of a dozen Librarians, Navigators, and Astropaths who battled the Tyranid Hive Mind in the Warp, Orion bears both physical and psychic scars from the ordeal. Promoted to Chief Librarian after the Third Aurelian Crusade, he made it his mission to prevent heresy from breeding within the Chapter as it did under his predecessor Azariah Kyras. In Dawn of War IV, Orion co-leads the Blood Ravens' survivors alongside Cyrus on Kronus.

Upon recovery, the newly-appointed Chapter Master Angelos promoted him to Chief Librarian.
