Ash drakes

A wingless relative of the Sand Drakes in Far Harad, Ash Drakes are the only creatures that inhabit the blackened desert of the Gaer Dûrlith. They lurk below the surface of the soft ash, waiting to spring upon unwary and unfortunate travellers. The drakes move through the ash swiftly, either by lumbering across the surface or "swimming" below. They seldom feed, and as a result attack with great ferocity.
