Avatar gaat over de wereldmacht die lange tijd verdeeld was over vier naties: Aarde, Vuur, Water en Lucht. Uiteindelijk werd het evenwicht verstoord en was er maar één Avatar die de situatie kon redden: Aang

A plague of shadows has swept across the land, turning innocent creatures into terrible monsters. One champion remains to battle the darkness and return the world to the light: Niko. Armed with his magic sword and guided by a determined Princess, young Niko journeys to the Curse-ed Volcano to face the evil sorcerer Nar Est and free his people from their magic prison.
