Memory:Greater water elemental

This elemental shifts and undulates, ebbs and flows, separates and rejoins, rises and falls, with a nearly hypnotic motion. However, the power contained beneath that smooth surface is unmistakable. As the fluid dance progresses, you hear the rumbling force of a glacier; you feel the terrible scalding of steam; and you witness the devastating power of a tsunami. Suddenly the elemental transforms into a geyser, driving you back with its awesome pressure! Your lungs cry out for air, as the world around you is filled with water. In its home plane it must possess god-like powers, and it brought an illusion of this world here. All your surroundings are steeped in a dark blue light, and the air seems a lot denser. Ghostly skins seem to span the gaps between your fingers and you feel like you're growing fins.
