AION: The Tower of Eternity is still under development by NCsoft, and any information related to the game is subject to change with the release of more information.

The word avatar was originally the name of an earthly incarnation of Vishnu (Hinduism). It has since become more common to refer also to any bodily or other familiar representation of any god. In the context of Aion, it has come to mean an iconic representation of a player in the game world.
