King of Omashu

The King of Omashu is a position held by the provincial ruler of Omashu. He is answerable to the Earth King, but exercises significant power and is relatively autonomous of the affairs of the capital. His power extends to both the civilian and military administration of Omashu, and probably the surrounding area. The current title holder is Bumi. The title ofking is probably passed down to the strongest bender in the city, and not by birthright. Since Aang didn't mention Bumi was royalty.
