The active volcanoes of the Sava'khar wasteland keep vast amounts of iron in a semi-liquid to liquid state. The unusual size of this lake of iron was caused by the Dûlan-Nûl Firestorm. The viscosity of the iron lake varies according to the intensity of the lava flows. Two active volcanoes border the north and south ends of Angaz Varn. They along with bubbling iron keep the air around the lake very noxious, and potentially toxic to some.
Numerous steel predators prowl the shores of Angaz Varn.
