About this creation
Sulfuros was originally an element less matoran sent to do medial labor in the Ta-Metru Sulfur mines. One day, he found a large vein of Sulfur only a few feet below the surface. Digging to the bottom, he found a large Toa stone. Remembering a book he had once read, he lunged. But before he cold grab it, he, the stone, and a huge pile of rock and sulfur fell downwards, landing in a pit of mutagen. A burning sensation surged through his body as the mutagen mutated him with the sulfur and the Toa stone. He was made a Toa and fought a number of makuta. Then, Quite suddenly he disappeared. When he returned, he and his team became raiders, he conquered vast amounts of land until defeated by a Toa army numbering in the thousands. Nobody quite knows where he and his team is now.
