Aang is visited in a dream by Roku, who tells him it is time the current Avatar learns about his past life's history with Fire Lord Sozin. Roku instructs Aang to travel to the former's old home, a deserted volcanic island, during the summer solstice. Upon arriving, Toph senses there is an entire village buried beneath the volcanic ash of the island's shore. As the solstice begins, Aang meditates and meets Roku in the Spirit World.
