Avatar Aang asks his friends to help him hor 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 the cause of the pollution Aang finds there or is something more mysterious happening? Written and drawn by the creative team behind the best-selling The Promise and The Search, Gene Luen Yang and Gurihiru, in collaboration with Avatar: The Last Airbender and Legend of Korra creators Michael Dante DiMarti and Bryan Konietzko, this is the ultimate continuation of Avatar and the perfect companion to Legend of Korra!
