At the beginning of time, the first Avatar received an amazing power from the spirits; he would be reborn in each lifetime as the master of all the elements. He would be the guardian of Middle Earth for all eternity, unless the avatar or one of his reincarnations was to die in the Avatar state of total power. For centuries none have ever truly known the price in which the Avatar bargained with the spirits, some say it was a price many before him had refused to pay. The Avatar became a god amongst the people with the ability to bend water, air, fire and earth; he represented balance and he represented peace amongst the nations. At the end of his days the Avatar became fearful of his future life and sought wisdom from the spirits, they told him the new Avatar would only remember part of his/her past lives and would have to train in order to be able to wield any of the other elements. The future Avatars would face many trials and it would be uncertain whether or not they would succeed. The spirits would tell him no more and for sometime they ignored his desperate cries for help, leaving him alone and uncertain. A spirit took pity on him and answered his prayers with a solution, in the farthest reaches of the Spirit Realm live the oldest spirits and amongst them, two of the most powerful: The Yin and Yang. With his dying breath the Avatar selfishly bound the spirits to him so that they would always be there to guide the future Avatar along the right path.
