The Flooded Factory

From the introduction: Trying to create the ultimate being, Kallen made many horrific creatures using a powerful sphere. The device he created to control sphere's power broke, and his attempts to shut off the device were unsuccessful. His body started to dissolve before he could reach the sphere. He has remained there, so close to the edge of his journey, for hundreds of years. Removing the power source is the only way to end his curse.
