Not long after arriving in Camelot -- a majestic kingdom where magic is a capital crime -- young warlock Merlin (Colin Morgan) realizes that his true mission is to use his powers to protect the future king Arthur (Bradley James). Among the few who know of Merlin’s destiny are court physician and ex-sorcerer Gaius (Richard Wilson) and the dungeon-bound Great Dragon (voiced by John Hurt) in this family-friendly fantasy drama.
