Definitions for "Yugoloths"
In the Planescape campaign setting for the Dungeons & Dragons fantasy role-playing game, the yugoloths are denizens of the neutral evil planes of existence. The Tarterian Depths of Carceri is neutral evil, but is situated "next to" the Abyss, which bleeds some of its chaotic nature across the planes. The Bleak Eternity of Gehenna is nearer to Baator, and thus has some lawful evil attributes.
