Era of Raava (Earth-2213)

"And for the past ten thousand years, I have kept darkness under control and the world in balance."

The Era of Raava was an ancient period in history which encompassed the time period before the birth of the first Avatars around 9,829 BG. It saw the clash of Raava, the vessel of Hagoromo, and Vaatu, the Ten-Tails, the vessel of his mother, Kaguya after she ate the chi fruit from a God Tree.
