Zaire

Zaire is the Spirit Warlord, and the absolute ruler of the Spirit Realm. Considered one of the most legendary benders in history, partially due to the fact that the Warlords each possess unworldly powers, Zaire practices the usage of eldritch and spiritual energy, as well as summoning spirits, dubbed spiritbending.
