Beneath the surface, Ice Mountain is filled with a massive underground network that stretches far beyond the mountain's edges. Both the dwarves of Keldagrim and Imcando Dwarves have connected the mountain to the Dwarven Realm, leading to the establishment of subterranean Dwarven Mines, Camdozaal, and the Ice Mountain Dwarven Colony. The Kinshra formerly used the area as a slave mine, although today their only subterranean work on the mountain is in the Black Knights' Catacombs. Even further down is a complex river system where the Living Rock Caverns can be found.
