After beginning the Harmony Restoration Movement, an event that was meant to remove Fire Nation remnants from the Earth Kingdom, Aang agrees to end Zuko's life should he go down a path similar to his father, after the latter requests it, being stopped by Katara from entering the Avatar State as he began a later encounter with Zuko and then tries to mediate protestors and the Yu Dao resistance, afterward assembling members of a fan club and forming the "Air Acolytes", a group that he intends to teach the ways of the Air Nomads. Aang then participated in a search for Zuko's mother Ursa, successfully finding her and entering the Spirit World to assist in locating the Mother of Faces, convincing her to grant Rafa a new face. After a period of entertainment, Aang is contacted by his former life Yangchen, who tried contacting him about Old Iron's return. Aang also has a fight with the Rough Rhinos when they try to oust him from the Eastern Fire Refinery. Aang then aids in preventing Azula, disguised as the Kemurikage, from stealing any more children.
