ACCESS GRANTED: WELCOME TO THE WORLD OF AVATAR

"Water, Earth, Fire, Air.”

Only the Avatar, can master all four elements and bring balance to the world. And each new era brings a new challenge. For the struggle between balance and chaos is eternal. The Avatar, formed initially when Wan permanently fused with Raava during the Harmonic Convergence of 9,829 BG, is the human embodiment of light and peace through the connection with the Avatar Spirit.

As the only physical being with the ability to bend all four elements, it is considered the Avatar's duty to master the four bending arts and use that power to keep balance and peace among the four nations of the world, as well as between mankind and spirits. Upon death, the Avatar Spirit causes the Avatar to reincarnate into the next nation, dictated by the cyclic order: fire, air, water, and earth. Mirroring the order in which the first Avatar, Wan, learned the elements, this is also the traditional order in which any one incarnation is to master the elements, beginning with the bending art of the Avatar's birth nation.

The reincarnation cycle can only be broken if the Avatar is killed while in the Avatar State, Raava is removed from the Avatar and severely injured, or the Avatar Spirit is compromised by a spiritual infection. As part spirit, the Avatar possesses an innate connection to the Spirit World and is at their strongest in that realm, due to being surrounded by spiritual energy.

The Avatar used that connection to the Spirit World to be the bridge between the two worlds in order to keep peace between them and ensure harmony. Now, the avatar cycle continues after Korra's peaceful death due to age, now a new avatar is born from the earth kingdom, and its you.
