Ghoul

"We've been unable to establish contact with any of the Houses of Lesser Faery who reside within Maizan-controlled territory in the vicinity of those closed World Gates. Not fairies, nor dryads and naiads, not even any of the carrion eaters, ghouls, trolls, and the like."

—Manya, in Shadow Dawn

Ghouls were a race of Lesser Faery that fed exclusively off carrion. As a consequence, the presence of corpses attracted ghouls, which, in turn, often attracted trolls.
