Rise of The Elemental Hero

Your main character, a poor fisherman’s daughter, discovers she has the power to control water.

Conceptualize a world that’s divided into elemental kingdoms – water, fire, earth, air, etc. What would happen if an ordinary girl from a humble background suddenly discovers she has the power to control one of these elements? How would she use this ability, and what kind of obstacles would she face? The themes can explore self-discovery, the fight against oppression, and the moral duties accompanying power.
