The Groith are a malevolent race that worships Nyarlathotep and whom are enemies of the Dominion of the Black. They inhabit rogue worlds, residing in dark spire cities that are ruled by elders. Grioth use portals to travel to other worlds, to pillage them for resources. Physically they are batlike humanoids with four narrow eyes and a long ratlike tail. Many of them have been mutated by the Dark Tapestry into deformed or lumbering beings. The Elder possess unusual psionic powers, which aids the Grioth against their mortal enemies, the Dominion of the Black.
