Nukekubi

Nukekubi were creatures of the Shadowlands similar to Pennaggolans, but less intelligent and devious. They appeared to be human, but at night their heads detached from their bodies, sprouted sharp fangs, and float away in search of prey. They fed on the pain and death-terror of their victims, tearing them to pieces. Their skills at deception were limited, and preferred to keep moving before their depredations drew too much attention.
