The Great Volcano was a location on Bara Magna and Spherus Magna. It was located in the center of the Valley of the Maze and was ruled by the Element Lord of Fire prior to the shattering. Unknown to many including the Element Lord of Fire himself was that it was actually a power source used by the Great Beings and a fortress in disguise. Mata Nui and Tarduk found a power source here and used it to power the prototype robot.
