The Avatar Kaji Yenn, master of all four elements is being challenged by the Firyane, a group of benders and non benders alike, who destroy everything they can that is in their way. They do not like peace, which is why they need to get rid of her. Kaji still has to master all of the elements, being only thirteen. She leaves with her friend Geoung, and now needs to find some of her masters. She, however, doubts she can defeat an entire group of people and their feared leader, Tyun. A mirthless murderer.
