Morlock

Morlocks (known among themselves as Mur'lok) are a vicious race of humanoid mutants that inhabit certain cave systems and mine shafts across the wasteland; notably the American Wasteland. Rarely seen in the light of day, Morlocks live in widespread subterranean communities that worship a dark entity that they call Mal'hool. An uncommon sight to those that live above ground, they are typically regarded as superstition.
