The Mask of Maliban

Hob, the magic mask maker, escapes from prison and is up to no good. To stop him, Eric, Julie, and Neal must travel to the city of Tortu, where Hob has sought refuge and is crafting a new mask for Prince Maliban. The mask will give Maliban power over all of Droon. It sounds like one of evil Lord Sparr's schemes, but he's been missing for some time. Could Prince Maliban be Lord Sparr in disguise?
