A hordling is one of many fiends that form the hordes of the Gray Waste of Hades. Hordlings wander the Gray Waste preying upon everything they come across, even other hordlings. Hordlings vary greatly in appearance. It is said that Hordlings evolved from larvae whose hatred was so unique, their souls became individual. The hordlings can be summoned using an artifact known as the Bringer of Doom, which was created around the time of the Invoked Devastation of Greyhawk. Hordlings are the most common inhabitants of the Gray Waste. They also occasionally roam the other Lower Planes as well.
