Gorbad Ironclaw is one of the most infamous of all Orc Warbosses. In his day, Gorbad led a massive invasion that almost crushed the Empire. His armies succeeded in slaying Emperor Sigismund and wiping the Imperial province of Solland off the map. Gorbad was a hulking Orc who rose to fame as the leader of the Ironclaw Tribe. It was he who first built the Iron Rock, the most redoubtable Orc fastness in the Old World. Yet conquering greenskin tribes was no real challenge for Gorbad and so he inevitably crossed into the human land of the Empire.[1b]
