The Librarians serve as the psychic warriors among the Space Marines, possessing the ability to channel their psychic powers into battle.
Those who prove themselves worthy have the privilege of donning the revered Terminator armor of the first company, granting them the means to enhance the effectiveness of elite infantry spearheads.
Whether engaged in intense boarding actions, fierce urban combat, or standing on the front lines against overwhelming enemy forces, they lend a lethal psychic advantage.
The newly introduced Librarian is equipped with the finest armor crafted by the Chapter, known as artificer-wrought armor, which bears intricate engravings of protective wards designed to counteract any adverse effects of their psychic abilities.
