Following the defeat of Fire Lord Ozai and the end of the Hundred Year War, Aang and his friends believe they can finally begin rebuilding their lives. But ending the war was only the beginning.
With Zuko now Fire Lord, the young ruler faces opposition from powerful members of the Fire Nation who refuse to abandon the empire his father built. Across the Earth Kingdom, Fire Nation colonies struggle to determine their future, creating tensions that threaten to reignite the conflict between the nations.
As Zuko works to restore his nation's honor, Aang, Katara, Sokka, Toph, and Suki travel across a changing world, helping communities recover from the devastation of the war. Along the way, Aang discovers that maintaining peace may be an even greater challenge than defeating his enemies—and that his responsibilities as the Avatar have only just begun.
Through friendship, music, and the power of the four elements, Team Avatar must confront a new generation of challenges and decide what kind of world they want to create.
