You were from the southern water tribe who lived in glaciers, and at the same time you were a water master. One day you went with your friend Katara and her older brother Sokka to fish in the frozen water.

You found something strange and Sokka thought it was a great idea to start hitting the ice with his boomerang and of course, the ice began to break but from there a strange ball came out that they broke.

Inside there was a boy next to a flying bison and he was unconscious.
