Uzkulak, also known as the Place of the Skull, was the seat of the Dwarfs of the East before the Great Catastrophe turned them into Chaos Dwarfs.[2a] Around 1000 IC, in order to fuel the ever increasing demand for slaves, a great sea canal was constructed underground linking the Falls of Doom to the north of Zharr-Naggrund with the Sea of Chaos to the west of Uzkulak, giving the Chaos Dwarf fleet an exit in the north.[1a]
