The Afinite Rebellion

Anastacia was born as an Afinite, the lowest ranking(despite weiling power) in human eyes.
Far from being powerful and respected, they were shunned and looked down upon for a) there were very less of them, and b) humans saw this as a chance to make use of their powers for their own benefit.
People started "hiring" them, and they were assigned to a task suited for their power. They had elemental manipulation, most powerful being called Kyniytae, who were able to control all aspects of elements.
Anastacia was born to manipulate Liquid, not only water. She was the only one.
Afinites had to reclaim a piece of land that once belonged to them, but were taken over by humans.
Anastacia would need friends along the way to reclaim Helia, the land of Afintes.
