During their voyage, the group encounters Merlin, an ancient magician, who offers to take Presto in as his apprentice if he agrees to leave his friends and stay at his tower forever. Presto hastily agrees, though what he discovers about Merlin’s offer doesn’t please him as much as he had initially hoped.
