Notes

Avatar Aang asks his friends to help him honor Yangchen's Festival -- one of the highest Air Nomad holidays, which hasn't been celebrated in over one hundred years. But cryptic visits from the spirit of Avatar Yangchen herself lead Aang to discover a jointly owned Fire Nation and Earth Kingdom refinery -- operating on land sacred to the Airbenders! Is this simply a case of corporate greed or is something more mysterious happening?
