Avatar: The Lost Earthbender
After the death of Avatar Korra, The Whole world entered an Era of Peace and Balance established by Korra. It became a better place and nearly perfect.
Over time, when the next Avatar did not show up, People from all over the came to a final conclusion: The Cycle of Avatar has ended.
Avatar Korra became the last Avatar and as stated by her, The Avatar Cycle was broken when Rava, the spirit of Light was forced out of her body and was beaten badly by Vatu, the spirit of darkness on the day of Harmonic Convergence. Although Avatar Korra defeated Vatu at last and again re-bonded with Rava, her connection with the other Avatars broke apart and so was the Avatar Cycle.
Peace and Balance lasted in the world for another fifteen years when a new threat appeared from the depths of darkness and the balance was once again disrupted. Nations tore apart in a newly waged war and chaos surrounded the whole world.
It was then, The next Avatar revealed himself to the world. The new Avatar was an Earthbender named Aaron. He must retrieve what was lost by his past life and once again restore balance in the world while fixing the errors made by the last Avatar, Korra.
