In his personal history the Barbarian defeated [http://diablo2.diablowiki.net/Baal Baal], only to learn from [[Tyrael]] that the Worldstone was corrupted and would have to be destroyed. The destruction of the Worldstone blasted Mount Arreat to rubble, destroying the remainder of Baal's army and saving the Barbarian lands from their invasion.

Twenty years later, when [[Diablo III]] takes place, the Barbarian lands are largely deserted, and the only remains of Mt. Arreat, formerly the symbol of the lands and the source of the Barbarians' spiritual strength, is a huge crater.
