Merlin is a young wizard who arrives in the kingdom of Camelot after his mother arranges for him to stay with the court physician, Gaius. He discovers that the king, Uther Pendragon, has outlawed magic and imprisoned the last great dragon deep under the kingdom. The dragon tells Merlin that he plays an important role: to protect Uther's son, Arthur, who will bring forth a great kingdom. When Merlin meets Arthur, he believes that he is an arrogant bully and Arthur, likewise, has a less than stellar opinion of Merlin. Merlin must keep his magic secret or face being executed by Uther.
