Who are the Dwarves
In the ancient times, after the Titans departed Azeroth, their children, known as the earthen, continued to shape and guard the deep recesses of the world. The earthen were largely unconcerned with the affairs of the surface-dwelling races and longed only to plumb the dark depths of the earth.
When the world was sundered by the Well of Eternity's implosion, the earthen were deeply affected. Reeling with the pain of the earth itself, the earthen lost much of their identity and sealed themselves within the stone chambers where they were first created. Uldaman, Uldum, Ulduar... these were the names of the ancient Titan cities where the earthen first took shape and form. Buried deep beneath the world, the earthen rested in peace for nearly eight thousand years.
Though it is unclear what awakened them, the earthen sealed within Uldaman eventually arose from their self-imposed slumber. These earthen found that they had changed significantly during their hibernation. Their rocky hides had softened and become smooth skin, and their powers over stone and earth had waned. They had become mortal creatures.
Calling themselves dwarves, the last of the earthen left the halls of Uldaman and ventured out into the waking world. Still lulled by the safety and wonders of the deep places, they founded a vast kingdom under the highest mountain in the land. They named their land Khaz Modan, or "Mountain of Khaz", in honor of the Titan shaper, Khaz'goroth. Constructing an altar for their Titan father, the dwarves crafted a mighty forge within the heart of the mountain. Thus, the city that grew around the forge would be called Ironforge ever after.
The dwarves, by nature fascinated with shaping gems and stone, set out to mine the surrounding mountains for riches and precious minerals. Content with their labors under the world, the dwarves remained isolated from the affairs of their surface-dwelling neighbors.
