Like its predecessor, the series is set in a fictional world inspired
by Asian and Inuit cultures, and inhabited by people who can manipulate
the elements of water, earth, fire or air through an ability called
"bending." One person, the "Avatar," has the ability to bend all four
elements. Reincarnating in turn among the world's four nations, he or
she is responsible for maintaining peace, harmony, and balance in the world.
