Lore

Yugoloths are fickle fiends that inhabit the planes of Acheron, Gehenna, Hades, and Carceri. They act as mercenaries and are notorious for their shifting loyalties. They are the embodiments of avarice. Before serving under anyone's banner, a yugoloth asks the only question on its mind: What's in it for me?
