Tuid'ya is an entity that inhabits the Zustruh waters. He is humanoid in shape but appears to be a black smoky mass almost tendril like. A mask lies where his face would be, and is made of the horns of the Zustranian Whales. He does not follow the laws of physics and is able to ignore gravity, blip in and out of our dimesion, and shape reality itself. Some say he existed before time. Some say he was a being who reached omnipotence. No one really knows. All we do know is that he is conected to the whales and has more power than any of us.
