In the rich world of Avatar: The Last Airbender that draws heavily on East Asian philosophies, mythologies, and martial arts, there exists four main nations, each aligned with a classical element: Water, Earth, Fire, and Air. The people of these nations have individuals known as 'benders', who have the rare skill to control and manipulate the element associated with their nation. The balance of these nations and benders, however, is held together by a special being known as the 'Avatar' – a spirit of the world manifested in human form, who alone can master all four elements and who also serves as a bridge between the physical and spiritual worlds.
