Merlin arrives at the city of Camelot, where the king, Uther Pendragon, has outlawed magic and imprisoned the last dragon. Merlin, who was born with extraordinary magical powers, is taken as the apprentice of Gaius. Merlin later discovers, after being informed by the last dragon, who is held as a prisoner deep under the city, that he has an important destiny in protecting Uther's arrogant son, Arthur, so that he may grow up to found a great kingdom.
