After a sore defeat in the Fire Nation on the Day of Black Sun, the elders of the invasion force are now prisoners and the gang travels to the Western Air Temple for refuge. Appa becomes tired from carrying so many people, so they have to walk on foot. When they reach a cliff that descends into a misty canyon below, Toph exclaims that they have arrived at the temple, though no one else sees it. Aang realizes they have indeed arrived, as the temple is built on the underside of the cliff.
