Jonah Orion is a Librarian of the Blood Ravens Space Marines. He has served under Captain Gabriel Angelos since the aftermath of the Tartarus campaign. As a former protégé of the late Isador Akios, who was corrupted by Chaos on Tartarus, Jonah was subject to suspicion; but the support of Captain Angelos and Chapter Master Kyras soon put those doubts to rest. During the Aurelian Crusade, he was one of the psykers tasked with battling the Tyranid Hive Mind as Angelos was en route to Aurelia. Jonah was the sole survivor of the dozen Librarians, Navigators, and Astropaths that accompanied Angelos, and still bears the scars of his ordeals in the Warp. His psychic abilities have allowed the Blood Ravens to root out several leftover pockets of Tyranid infestation over the last year.
Jonah dies battling the ascended Azariah Kyras on Cyrene.1 (Regardless of campaign choice.)
Jonah Orion is equipped with a Force Staff and carries several psychic tomes that allow for the use of different psychic abilities. He may also equip a Force Sword and plasma pistol. If the player chooses the Path of Chaos Jonah can be equipped with Forbidden Tomes that grant him dark sorcerous powers such as The Chains of Torment. He can also equip the Book of Lorgar which greatly increases his abilities but corrupts him significantly.
