Water Elementa

He has the power to control water or at least try to modify its shape, for now he can barely control his power, which may seem like a very basic magical movement, but he knows he can do more than just make a floating sphere of water in the air or small columns of water.
When he discovered this at first, it was very shocking, how did he get it? or, why did he get it? after some practice he no longer sees this as a curse, at least he knows a very basic ability to control water, and he uses it as a form of entertainment when there is nothing else interesting to do, or if he just wants to relax, other than using this as a distraction, what if he can use this as a weapon? 
He even has a special place where he can do that kind of thing alone, it's like a huge lagoon, with a waterfall at the beginning, a place to relax, and play with.... water?
