Avatar: The Last Airbender - The Promise Part 3

The Harmony Restoration Movement has taken a turn for the worst as Earth King Kuei and Fire Lord Zuko lead their armies into battle in order to achieve their opposite intentions for the Yu Dao colony: Kuei wants the colonials to leave for the Fire Nation, and Zuko plans to keep his people where they believe they belong. As the two nations enter conflict once more, Aang and Katara attempt to negotiate peace within the city's walls while Sokka and Toph meet with an old friend at the Metalbending Academy. If war is to be averted, Team Avatar must find a way to resolve the Yu Dao crisis. Aang may be able to do so with his only option: keeping his promise to Fire Lord Zuko.
