Description & History
Monster Isle is a small desert island with a single mountain peak located somewhere in the South Pacific, not far from the island of Japan. Underground caverns beneath the desert lead down into a vast warren of caves and caverns that has since come to be known as Subterranea. Many years ago, a disgruntled nuclear engineer named Harvey Elder decided to disassociate himself from humanity and went on a quest to find the center of the Earth. His journey brought him to the East where he fell victim to an avalanche while mountain climbing. When he awoke, he found himself washed up on the shore of Monster Isle, but the fall had made him permanently blind. Harvey found the warrens that led to Subterranea and there he discovered various races of bizarre underground dwellers. Dubbing himself the Mole Man, he became their king and declared himself ruler of Subterranea.
