The decades following Yakone's exile were comparatively quiet. When Aang died at the age of 66, that changed: the Order of the White Lotus were sent to search the Water Tribes for the next Avatar, Aang and Katara's daughter Kya returned to the South Pole to support her mother, and Tenzin, suddenly the leader of the Air Nomads and the only living airbender, stepped into a leadership position unlike any other. Korra, cognizant of her Avatar status from a startlingly young age, was found, installed in a training compound, and prepared for her role as the bridge between worlds.

But as the events of "The Legend of Korra's" first season revealed, that role had changed massively. The world was rapidly industrializing, exposing a schism between benders and non-benders barely examined by "Avatar: The Last Airbender." Amon seized this opportunity, leading the Equalists, his movement to end bending, to a frenzied peak of popularity centralized in Republic City. Though Korra, then struggling with airbending, made more than a few missteps in handling Amon, her first major challenge as the Avatar, she ultimately stopped him and his followers alongside new friends Mako, Bolin, and Asami. The threat had passed, but Republic City was forever changed — and Korra, having briefly lost her bending to Amon, was as well.
