Staff of Sorcerer-Thane Thaurissan

Sorcerer-Thane Thaurissan was the leader of the Dark Iron dwarves during the War of the Three Hammers. When he lost Ironforge to the Bronzebeard clan, Thaurissan retreated to the Redridge Mountains and founded a city in his name. In a desperate attempt to defeat his enemies, Thaurissan accidentally summoned the demigod Ragnaros, which resulted in the sorceror-thane's immediate death and the formation of the volcanic peak of Blackrock Mountain.
