Perturabo

Perturabo, sometimes called the "Lord of Iron," "The Breaker" and "The Hammer of Olympia," is the primarch of the Iron Warriors Traitor Legion, one of the original twenty Space Marine Legions. Weaned on war and intrigue in the strife-ridden courts of his homeworld of Olympia, Perturabo was a grim warrior and master of technological arcana who wielded logic and the mathematics of warfare as keenly as he did a blade and Bolter.
