Water Dominion

The Water Dominion is one of the world's six nations, but technically does not qualify as one of the original four, although it follows the same principles and is descended from that same nation. Inhabited by waterbenders in a continent in waters southwest of the North Pole (northwest from the Fire Nation), it and its land was discovered by Marshal Larousse of the Northern Water Tribe when his ship set sail to find a new area during a time of economic decline. Larousse founded the nation, causing an enormous flock of Water Tribe people to the new land, as it entered its developing stage. It is ruled by the Water Warden, who acts as a constitutional monarch.

The Dominion soon became a full-fledged, economically and militarily durable nation, due to the large amounts of assistance and support gained from other nations, including the United Republic of Nations, and a spike in popularity.
