Blackrock Mountain is actually a volcano that was created at the end of the War of the Three Hammers when the Dark Iron dwarf Lord, Thaurissan, accidentally summoned Ragnaros the Firelord from his prison beneath the earth. The power unleashed by his “rebirth” was so massive it shattered a large section of the Redridge Mountains creating the areas now known as the Searing Gorge and Burning Steppes. Ragnaros enslaved the Dark Iron dwarf clan, and they have dug many tunnels and created a huge underground city in the depths of the mountain. Dwarves would later name this mountain Blackrock Spire. The name Blackrock Mountain and Blackrock Spire predates the coming of the orcs. Blackrock Spire is the part of Blackrock Mountain that is above ground, and Blackrock Depths is the parts underneath the mountain.
