Merlin and a young thief embark on a dangerous quest to find the Holy Grail and save Camelot.

Balthazar Blake is a master sorcerer in modern-day Manhattan trying to defend the city from his arch-nemesis, Maxim Horvath. Balthazar can't do it alone, so he recruits Dave Stutler, a seemingly average guy who demonstrates hidden potential, as his reluctant protégé. The sorcerer gives his unwilling accomplice a crash course in the art and science of magic, and together, these unlikely partners work to stop the forces of darkness.

Krabat, a beggar boy, is lured to become an apprentice to an evil, one-eyed sorcerer. With a number of other boys, he works at the sorcerer's mill while learning black magic. Every Christmas one of the boys has to face the master in a magical duel, where the boy never stands a chance because the master is the only person who is allowed to use a secret spell: The Koraktor.
