Two centuries before Common Unification, the great dwarf smith Durgeddin the Black and his clan were driven from their home in the southern Crowncrest Mountains by a horde of fierce orcs and trolls. The horde plundered the dwarves' ancestral halls and slew all they could catch. Fleeing his enemies, Durgeddin led the destitute remnants of his clan in search of a new home. After years of wandering, the dwarves discovered a great cavern system beneath the Stone Tooth: a rugged, forested hill crowned by a bare rocky crag.
There, Durgeddin and his followers founded the stronghold of Khundrukar, and used the fort as a base with which to wage decades of raids on orc tribes to the mountains north of them, coordinating with the Griffon-keepers of Skypeak to employ guerilla-like tactics on the tribes. Eventually, a member of Durgeddin's clan was captured by a powerful orc tribe during a raid, and the orcs learned of their enemy's hidden stronghold. The orc chieftains raised a great army and marched on Khundrukar. In a hard-fought siege lasting months, the orcs tunneled around the dwarven defenses. When they finally stormed the place, they put all within to the sword, then carried off wagonloads of booty.
In the years since the great battle, various creatures occupied the fort and used the place as a base for their raids. At other times, the caverns remained empty, save for the mindless and bloodthirsty monsters that haunted such places. Legends of the extraordinary blades forged in anger still surfaced from time to time in the lands near the Stone Tooth, inevitably resulting in adventuring bands exploring the tunnels, such as in Forge Of Fury.
