S03E19 Sozin's Comet: The Old Masters (2)

On the island, Aang looks to his previous incarnations for advice but is left dissatisfied with their responses. He soon discovers that the island is actually a lion turtle, which ultimately provides him with the insights he has been longing for. Meanwhile, unable to locate Aang, his friends resolve to search for Iroh instead. As they pursue him, they encounter The Order of the White Lotus, an organization that unites individuals beyond the boundaries of the four nations.
