The Air Nomads were a highly spiritual group of people. While nomadic, Air Nomads did inhabit four major air temples, each built on remote locations, only easily reachable with flying bison. The Air Nomads were a civilization composed of people who practiced the art of airbending. Each location has unique geographical layouts, civilizations, climates, and demography, and each one has a diverse range of landforms. At the end of the Hundred Year War, Fire Lord Zuko and Avatar Aang transformed the Fire Nation colonies located in the Earth Kingdom into a fifth independent realm, the United Republic of Nations. The world is divided into four separate nations: the Water Tribes, the Earth Kingdom, the Fire Nation, and the Air Nomads.
