The sorcerer-thane Thaurissan was the ruler of the Dark Iron Clan. He launched simultaneous assaults on the Bronzebeard city of Ironforge and the Wildhammer city of Grim Batol, later known as the War of the Three Hammers.
Both attacks were defeated, with King Madoran Bronzebeard defending Ironforge against Thaurissan, and Thaurissan's wife Modgud slain by King Khardros Wildhammer. The combined Bronzebeard and Wildhammer armies marched south to the city of Thaurissan in the Redridge Mountains, the Dark Iron capital.
Sensing impendeding defeat, Thaurissan summoned Ragnaros the Firelord into Azeroth. Thaurissan was killed in the resulting cataclysm, which formed Blackrock Spire and halted the advance of the Bronzebeard and Wildhammer armies.
The current ruler of the Dark Irons, Emperor Dagran Thaurissan, is descendant of Emperor Thaurissan.
