Commissar Yarrick Commissar Yarrick is one of the greatest heroes in the entire Imperium. On Armageddon, it was Yarrick who inspired the Imperial Guardsmen to prodigious acts of sacrifice and courage. Indeed, so motivated were the soldiers in Yarrick’s presence that not a single soldier was executed for cowardice, even in the face of overwhelming odds. It was at Hades Hive that Commissar Yarrick fought his hardest battle, and where he lost his right arm to the snapping battle klaw of an Ork Warboss. Fighting through pain and shock, Yarrick beheaded the Warboss and took that same klaw as his own, a symbol of his defiance against the Orks.
