Demeter is one of the first wave of Ocean Masters hired by Three Rings. She is governor of Alpha Island, one of only two Ocean Master-controlled islands on the Midnight Ocean. In Greek mythology, she is the goddess of agriculture and was endlessly generous until her daughter Persephone was kidnapped by Hades. Demeter refused to let anything grow. When the other gods went to get Persephone, Hades had tricked Persephone into marrying him. A compromise was reached.
