Aqua

Aqua or also known as the power capable of control over water sourses is good for fast transport and defence .The controller can shift the water into different shapes (mostly giant snakes) that look and act alive .The body of the water user can completely turn into water ,allowing them to blend in with the surroundings as puddles .Aqua doesnt cause a lot of distruction but judging by old information in the records,the controllers have a chance of drowning in their own power in case of a terrifying nightmere .For the control over the element is needed a lot of concentration and to be somewhat mentaly stable.
