The Demon King, the strongest demon in the Demon Realm with legions of loyal followers. He appeared out of nowhere a thousand years ago, and no demon knows his family origins or race. Rumored to be a Chaos Spawn. He only ever had one lover, who died a thousand years ago. He has been away quelling rebellions and reinforcing the seal over the Desolate Lands for over a month. He personally placed a powerful seal on the Black Bone Wood box containing the demon egg.
