Īt the start of the Hundred Year War, the Western Air Temple's population was killed by the Fire Nation during the Air Nomad Genocide and its aftermath, though the temple itself escaped significant damage. When the renegade order known as the Guiding Wind sought to break the relationship between the Air Nomads and the wealthy elites of other nations and criticized the temples for undermining the spiritual growth of all peoples, the West began to officially view them as too opposed to tradition. All four air temples eventually agreed to the construction of the Fire & Air Center of Learning in the Fire Nation with the support of the nation's nobility so that their teachings could be promoted elsewhere. Over two centuries later, by the life of Avatar Roku, the West and the other temples sought to forge close ties with the leaders of the other nations in hopes of helping more people. ĭuring the adolescence of Avatar Kyoshi, the Western Air Temple, along with its counterparts, pursued a highly isolationist policy as the Air Nomads sought to ignore worldly concerns to focus on preserving spiritual knowledge for generations to come. Yangchen later left the temple to master the four elements, with Master Boma making an oath to the elders to keep her safe. Jetsun was honored as an elder and an Avatar companion who had given her life to protect the bridge between humans and spirits at her funeral. While Yangchen was able to return to her physical body, Jetsun was not, and the older nun soon passed away, as her body had been separated from its spirit. Jetsun, who she viewed as an elder sister, helped guide her into the Spirit World for the first time in a meditation circle in a meadow above the cliffs. Yangchen's visions meant that she had discovered that she was the Avatar by the age of eleven.

Librarian Tsering and Sister Jetsun helped soothe Yangchen by researching who she was talking to and reading aloud historical excerpts. Before Yangchen was eight, the nuns witnessed her incoherently babbling to people who did not exist, and learned that she was having strong visions of past Avatar companions that could sometimes turn into "waking nightmares" if she recalled traumatic experiences. Dagmola and the other senior nuns learned that a girl under their care named Yangchen was the next Avatar. Abbess Dagmola was in charge of the Western Air Temple shortly after the death of Avatar Szeto.
