Gehenna

One of the lower planes, Gehenna borders Shadowfell and Shadowhell. It is smaller than the other planes, consisting entirely of four molten mountains constantly under erutping volcanic activity. Not many fiends call Gehenna home, as the more lawful Devils found themselves drawn to Hell, and the more chaotic Devils found themselves drawn to Hades. However, the barren mountains of Gehenna is the birthplace of the Yugoloths, an army of mismatching fiends not tied to any plane that were under command of a coven of night hags employed by Asmodeus. Other fiends found here are most likely hiding from a greater power or fiends exiled, and cast aside.
