Tigurius
From Lexicanum
Varro Tigurius is the Chief Librarian of the Ultramarines. He was appointed this rank after many years of fighting and because of his deep knowledge of the galaxy and his immense psychic powers.
His accomplishments include surviving the Ork attack on Boros alongside very few others as well as witnessing the arrival of the mysterious Legion of the Damned. He is one of the foremost experts in fighting the Orks in the Imperium, and has guided Marneus Calgar on the best ways to strike at the Ork empire of Charadon to prevent a fully formed Waaagh! from rampaging throughout the area.
Tigurius himself is unique among the Imperium's psykers, in that he has the ability to forsee tactical events and invasions by the enemy before they actually happen, giving his Chapter Master Marneus Calgar the opportunity to counter them before they even begin! These mysterious premonitions usually come in the form of dreams or small seizures, but were most people would see this as a gift, there are a few within the Imperium that are suspicious and perceive it as delving into the dark ways of Chaos, but the Chief Librarian's loyalty to the Emperor is clearly unquestionable, clearly shown by his bravery and valor when on the battlefield.
Though his visions have thwarted many enemies in the past, it would seem that the Tyranids in particular are more vulnerable to these premonitions than the Imperium's numerous other enemies. The sheer accuracy of his predictions about the movement and intents of the Great Devourer have led many to believe that Tigurius has managed to penetrate the Hive Mind itself, something only a psyker as powerful as the Emperor could withstand without going insane. If this is true, and the Chief Librarian of the Ultramarines really has tapped into the Hive Mind, it would make him the most powerful active psyker in the Imperium, second only to the Immortal God Emperor himself.
Tigurius wears the Hood of Hellfire, a modified Librarian hood which massively enhances his psychic abilities, and carries the Rod of Tigurius, a Bolt Pistol, and Frag and Krak Grenades.
