Cutthroat Island
In 1619, a pirate cutter, the Sea Devil, captured a Spanish cargo ship called Santa Susanna. Before reaching its destination the Sea Devil was caught in a storm and wrecked on the uncharted Cutthroat Island. Only one member of the crew managed to get off of the island alive, Fingers Adams. Before dying he made a map and tore it into three pieces which he gave to his legitimate heirs.
