In Dark Ages era Wales lives young apprentice magician Merlin — grandson of King Conaan, fostered by the family of Dafydd Ismena. Merlin's father is unknown; some say he was a demon of the night. His foster-grandmother, Myfanwy, who also possesses magical powers, is the only one to realise that Merlin's destiny lies at the court of King Arthur, and it is she who schools him in magic and witchcraft. However, due to circumstances surrounding his birth, Merlin is in constant danger from Vortigern, the Saxon High King, and his beautiful queen Rowena.
