Air Nomads were the collective people of the Airbenders. Though the people of this nation are nomadic, the Air Nomads raised children and situated their central governments in four monastic temples located at various ends of the globe, two for males and two for females. The four Air Temples are located on small archipelagos that were Air Nomad land (which is most likely abandoned now), on the tip of mountains and in one case hanging under cliffs.
The Air Nomads are loosely run by elder councils, one male and one female. The people are extremely spiritual.
In 0 ASC, the Fire Nation executed a mass invasion and genocide of the Air Nomads, wiping the nation into extinction save for the case of Aang, who managed to escape. It is sometimes referred to as the Air Nation in Fire Nation Propaganda.
