Ghouls

Ghouls are, for all practical purposes, sentient zombies. They are entirely carnivorous, and will survive so long as they eat meat and have a semi-intact head. They lack the ability to regenerate tissue without recent consumption of meat as well. Ghouls may also enter a rage when severely damaged that blocks out pain, and increases strength to enormous proportions, so much so that Ghouls often damage themselves terribly.
