Avatar The Last Airbender: Humo y Sombra Parte 1

Trouble in the Fire Nation!
After returning home to his family following the events of The Search, Zuko discovers that not all citizens of the Fire Nation welcome his return. Convinced that the young Fire Lord is unfit to succeed his father—and encouraged by the Kemurikage, terrifying spirits long thought to be only a myth—a secret organization known as the New Ozai Society plots to assassinate Zuko and restore Ozai to power.
