The Slag Pit lies deep within the Cauldron excavation site in Searing Gorge. It is run by cruel Dark Iron dwarves and worked by their slave laborers. Within the depths of the Slag Pit there is another danger, ravenous Incendosaurs. The Dark Irons are extremely hostile to any who would interfere with their mining operations.
After the Cataclysm, the Incendosaurs inhabiting the lower reaches of the Slag Pit have moved above ground around the Iron Summit. Their former home is now populated by Searing Flamewraiths under the command of a level 50 elite elemental, Archduke Calcinder.
