Great unclean ones

Great unclean ones are the greater daemons of the chaos god, Nergal, the embodiment of death and decay. Great unclean ones are large, rotting and decaying daemons, spreading filth all over the place. You are a Vaal Hazak(MHW). You were resting under your pile of corps and flesh until you got teleported to a Great Unclean one.
