After a lapse of 100 years, the Avatar-spiritual master of the elements has returned. And just in the nick of time. The Four Nations (Water, Earth, Fire and Air) have become unbalanced. The Fire Nation wants to rule the world, and its first conquest will be the Northern Water Tribe. It's up to a 12-year-old Airbender named Aang to find a way to stop it. Join Aang, Katara, Sokka, Momo, and Appa as they head north on the adventure of a lifetime. Only the Chosen One can restore the world order. This adventure, set in a fantastical Asian-influenced world, follows the story of Aang, the Chosen One, who must forgo his selfish wandering to learn to master his latent powers over the four elements.
