Lilophea, the Bride of the Sea King

Princess Lilophea lives in an island kingdom where a tropical paradise reigns during the day and fires are lit on the shore at night to escape the armies of monsters that come from the sea. The king and the sea king are longtime enemies. One day the sea king infiltrates the ball to woo the princess and present her with magical gifts. Does he want to seduce her to get back at her father, or does the sight of her make the water king's heart flutter with ordinary earthly love?
