Sapphire and Franz try to prevent the King and Queen from being executed, but they are too late and the King and Queen are dropped in the sea. This culminates in the final battle, as Sapphire heads off to Silverland castle to confront Mr. X with the aid of three magic balls. Given to Sapphire by her parents, the balls represent the three kingdoms and are supposed to save Silverland: they are used at first to ring the kingdom's bells, magically giving to the people the will to fight the invaders.
