The Air Nomads were a peaceful group of people who historically abstained from violence. Some factions within the Air Nomads had been violent and fought against other groups of people.
Elder Council
The Air Nomads were led by a council of elders.
Flying Bisons
Air Nomads were known for using Flying Bisons to travel. Most airbenders had strong bonds and great respect for their bisons. They were not merely seen as pets, but rather viewed as family members.
Vegetarians
Historically, Air Nomads did not eat meat as they believed there was no need to consume other living organisms. Their culture often discouraged binge eating as well. Air Nomads enjoyed mixing it up between fruit pies, vegetable soups, juices, tea, crackers, nuts, trail mix, and enjoying bread.
Life of Detachment
Air Nomads had strong morals and often discouraged people from getting too attached to "materialistic pleasures". They focused more on eternal and spiritual aspects of life over temporary physical ones. Some air nomads discouraged copulation amongst adults while others thought it was alright as long as attachment was avoided. Some nomads even discouraged marriage or any form of romantic intimacy while others said that it was best not to marry but it was better to marry than to "live bitterly with burning passion". Because of this, marriage was often accepted by Air Nomad groups over fornication.
