His clothes are the genteel, rotted garments of a generation ago, and he speaks in the tones of a reasonable man. His skin is sallow, almost parchment-like in texture. Only his taloned fingers, black split tongue, and cruel hooked teeth betray his deep corruption.

True ghouls (also called shadow ghouls or greater ghouls) are much more human than common ghouls and ghasts. They are as well-spoken and cultured as they are utterly ruthless and evil. True ghouls have pale skin, sharp teeth, a long black tongue and sunken eyes. Unlike most undead, the true ghouls are not the product of necromantic tinkering or magic. They are evolved ghouls who have managed to overcome their bestial and feral natures, or at the very least, have learned to control them.

True ghouls speak Undercommon. These creatures originally appeared in DRAGON #252, and were featured in DUNGEON #70's "Kingdom of the Ghouls" adventure. DMs seeking more information concerning true ghouls and the White Kingdom they rule are encouraged to seek out these sources.
