Avatar: The Last Airbender - The Search (2013)

A new lead has surfaced regarding the fate of the former Fire Lady Ursa. Her son, Fire Lord Zuko, has mobilized Team Avatar for a journey into the heart of the Fire Nation's past. Their mission requires the unique skills of an unlikely ally: Zuko's sister, Princess Azula, recently released from her institutional confinement. This tense coalition travels across the archipelago, following a trail of royal correspondence and half-remembered court whispers. The search pushes into forgotten villages and the overgrown ruins of the old capital, forcing each member to confront their shared history. The air grows thick with the scent of ash and unresolved grievances.
