Avatar The Last Airbender: La Brecha Parte 3

Avatar Aang calls on his friends to help honor the Yangchen Festival, one of the greatest celebrations of the Air Nomads, which hasn’t been held in over a hundred years. But mysterious visits from the spirit of Avatar Yangchen herself lead Aang to discover a refinery, jointly owned by the Fire Nation and the Earth Kingdom, operating on sacred Air Nomad territory! Is this merely a case of corporate greed run amok, or is there a deeper mystery at play?
