Set in the world of Avatar: The Last Airbender and Legend of Korra. It has been eighteen years since the Last Avatar, Korra, had passed away. The White Lotus were left to search in vain for the next Avatar. Unbeknownst to them, the Avatar's power has become too much for one person to contain. The spirit of Raava has been split into two bodies. Serefina has never fit in at the Fire Nation, and after the accident her temper has become uncontrollable. Nadia has always dreamed of leaving the North Pole and seeing the world. Fate will bring them together to finish a war that had started long before they were born.
This story is from two alternating points of view. Nadia's part is written by HarleyQuinnFlamebird.
