Avatar: The mystical tale of Asuna

It's been 16 years since Korra sacrificed herself to restore to the four nations and the spirit realm. And now danger looms over the world once again and the avatar cycle starts a new. Asuna is an earth bender unlike any other has seen before. Her form of earth bending comes from an art long since past and was taught onto her by the one being that gave the benders their bending. And that being is the last living lion turtle.
