Synopsis:

One hundred years before the start of the series, a 12-year-old Airbender Aang learns that he is the new Avatar. Fearful of the heavy responsibilities of stopping a continuous world war, coupled with the coming separation from his beloved mentor Monk Gyatso, Aang flees from home on his flying bison Appa. During a fierce storm, they crash into the ocean, and Aang’s Avatar state freezes them with waterbending in a state of suspended animation inside an iceberg.
