This follow-up series to "Avatar: The Last Airbender" is set 70 years after the events of "Avatar" and follows Korra, the next Avatar after Aang, who is from the Southern Water Tribe. With earth, water and fire under her belt, Korra must master the art of airbending. Korra's quest leads her to Republic City, a virtual melting pot where benders and nonbenders live together. But she soon discovers that the land is plagued by crime and a growing antibending revolution that threatens to tear the city apart. While dealing with the dangers, Korra begins her airbending training under the tutelage of Aang's son, Tenzin.
