Ultramarines Chief Librarian Tigurius Warhammer 40,000

Tigurius is the Ultramarines Chief Librarian and has always stood apart as a figure of mystery, possessed of knowledge that goes far beyond the towering datastacks and myriad scrolls of the Chapters Librarius. As the Chief Librarian of the Ultramarines Chapter, Tigurius is one of the most powerful psykers in the Imperium, and since crossing the Rubicon Primaris he can push his abilities even further. He also wears the Hellfire Hood, an artifact that increases both his chances of successfully manifesting psychic powers and also dispelling those of the enemy.
