The Spirit Realm is inhabited by the souls of deceased humans unable to move on, held back by their vice and grief. Often these souls manifest in forms that serve as a reflection of the individual's soul, based off their life, sins, and desires, with some resembling their past human forms while others are more monstrous or animalistic. Ruling over this realm are three demonic princes who serve as the embodiments of rage, desire, and misery.

The Prince of Rage is a draconic humanoid with a strong, muscular build, possessing a pair of large wins and curved horns, along with bright red eyes slanted downwards in a constant glare. The embodiment of wrath and anger, his domain is sprawling city inhabited by those held back by their resentment towards other humans or sent here as punishment for their crimes. They are free to do as they please, often harming and exploiting each other through one means or another, and he has come to resent humanity as a whole due to only ever seeing the worst it has to offer.
