Air Temple Island

Air Temple Island is the primary residence of Tenzin and his family, located off the coast of Republic City. The temple was originally built by Avatar Aang himself.

Comprised of several structures, including a large tower, several smaller buildings with blue roofs, and an open practice area, the Air Temple Island was where Tenzin, his wife Pema, and their three children Jinora, Ikki and Meelo found a home. When Korra was in need of an airbending master, the new Avatar moved here to be taught the ancient art from Tenzin, subsequently disturbing the serene life they had on the island.
