Western Air Temple

History
History: Along with the Eastern Air Temple, it exclusively housed female Airbenders. This temple was most likely destroyed by the Fire Nation. Aang and his friends headed to the Wester Air Temple for a safe place to stay after the unsuccessful invasion.

Customs
While other nations possess royalty and are run by monarchies, the Air Nomads are led by the monks/nuns of the Air Temples, i.e. by a theocracy.

The Air Nomads are the only nation comprised entirely of benders, due to the highly spiritual nature of their lives. It is said that meditation was an important part of the Airbenders' daily routines, as it helped them to focus their energies and understand the potency of their element.

The arrow on an Airbender's head signifies that he or she has mastered Airbending. This is an emulation of the natural arrows on the heads of Flying Bison, animals revered by the Air Nomads who can naturally Airbend and are believed to be the inspiration for the first Airbenders. As seen in the episode "The Storm," apprentice Airbenders have no tattoos. In order to receive the tattoos as well as the title of a master, an Airbender must pass the thirty-six levels of airbending along with engendering a new technique.

Natural resources and foods
As could be determined, air is the main and most significant power source and natural resource of the Nomads, as without it they would be rendered powerless. With the power of air channeled under their control, the Airbenders were enabled to defend and protect their homes and way of life and travel across the globe.

The Air Nomads were a tranquil and environmentally friendly race of people and did their best not to leave a mark on the land. Any industry that they engendered, such as farming and gardening, were powered naturally. They also produced their own food.

Air Nomads are also vegetarians, as are the modern monks of Tibet. This is suggested by Aang's words when he said he didn't eat meat in "The King of Omashu," as well as other various episodes.
