The Waterbender

Ura, a waterbending master of the Southern Water Tribe and one of the best healers in the world. During the fight with Unalaq/Vaatu, she was pushed into a Spirit portal, but instead of the physical world, darkness surrounds her. She is suspended in a void. Suddenly she is pushed into another portal, where she painfully landed on the ground, but before she went unconscious, she caught a glimpse of a kid wearing red and black. Just what will happen when she is in a different world with different rules and culture. And will she ever get back to her original world? Read to find out.
