"Avatar: The Last Airbender" takes place in a world that is home to humans, fantastic animals, and spirits. The world is divided into : the Water Tribes, the Earth Kingdom, the Air Nomads, and the Fire Nation. Each nation bases its society on the element (water, earth, fire, or air) that is in its name. Some people who live in each nation have the power to magically control and use, or "bend," the element of that nation. Those people are called "benders." They can use their powers of bending to fight. The way that the show portrays the fighting style from each nation is based on a martial art from real life. For instance, "waterbenders" (people who can magically control and use water) have a fighting style that is based on tai chi chuan from real life. Earthbending is mostly based on Hung Ga kung fu. Firebending is like Northern Shaolin kung fu. And Airbending is similar to baguazhang. Each nation is also connected to a season: autumn for the Air Nomads, winter for the Water Tribe, spring for the Earth Kingdom and summer for the Fire Nation.
