Jakob Tannen

Jakob Tannen is a member of the Imperial Sentinels, a notable 3rd Founding Successor Chapter of the stoic and proud Imperial Fists. He was a part of the initial intakes of candidates to become a part of the ancient Primaris Project, and underwent the necessary surgeries and augmentations to become a Primaris Space Marine - one of the next-generation of transhuman warriors that would surpass their Firstborn brethren. A talented battle-psyker of some renown, he rose quickly through the ranks of his Chapter's Librarium, and recently assumed command as the Chief Librarian of the Chapter.

Background
Jakob Tannen is the first of the Awakened Primaris to hold a position of authority in the Chapter. He was a Neophyte during the time of the Great Scouring and collected by Archmagos Belisarius Cawl's agents for showing exceptional psychic potential. For ten millennia he and the other Awakened would wait in stasis for the Imperium's darkest hour. Jakob fought as a Greyshield in the Indomitus Crusade for only a brief period of time as the Imperial Sentinels themselves were a part of Guilliman's forces. Three companies' worth of Primaris Marines were given to the Imperial Sentinels, including Jakob, who joined the ranks of the Chapter's Librarius almost immediately. From the moment of his induction he was leaps and bounds ahead of his peers, rising through the ranks from Lexicanus, to Codicier, and then Epistolary. It would be at Cressia where his Trial by Fire would occur, in the shadows of that Thrones' Forsaken planet Jakob proved himself a capable warrior and commander but beyond that a peerless combat psyker. On his return to the Chapter he was informed of the death of the previous Chief Librarian and once news of the mission's success traveled, elected as his successor unanimously by the other Librarians.
