Chaos sorcerers from Total War: Warhammer. These guys are humans or men of the north drawn to and corrupted by thier interest or study of the dark arts and more specifically their greed for knowledge and power. As these guys are Hero characters in the game we wanted to allude to some of the " gifts" that the chaos gods bestow on thier followers adding mutated chaos armor, fused with their flesh, they are beginning to deform into what will either become chaos spawns or mighty daemon princes.
