The mythical city of Camelot, in a time before history began, is a fantastical realm of legendary beasts and mysterious peoples. In this dangerous world, magic has been banned by the ruthless tyrant, Uther Pendragon. Merlin, a young man gifted with extraordinary magical powers arrives at the gates of Camelot as a young man, sent by his mother to start a new life. Though bright-eyed with wonder, the young sorcerer quickly makes enemies, including the heir to Uther's crown, the headstrong Prince Arthur.

Guided by Uther's wise physician, Gaius, Merlin is soon using his talents not just to survive but also to unlock Camelot's mystical secrets. And, as he does so, he discovers that his destiny and that of the kingdom's young leader in waiting, Arthur, are inextricably linked.
