Avatar: The Last Airbender takes place in a fantasy world, home to humans, fantastic animals, and supernatural spirits. Human civilization is divided into four nations—the Water Tribes, the Earth Kingdom, the Air Nomads, and the Fire Nation. Within each nation exists an order called "Benders" who have the ability to manipulate their native element. These Bending arts combine a certain style of martial arts and elemental mysticism. The Bending types are Waterbending, Earthbending, Firebending, and Airbending.
