Katie McGrath’s Morgana Pendragon began her journey in Season 1 as a complex heroine rather than a villain. The season laid the groundwork for her eventual turn, focusing on her unexplained prophetic dreams and her moral outrage at Uther’s tyranny. It was a slow burn that added tension to every scene she shared with the King.
In the finale, "Le Morte d'Arthur," Merlin travels to the Isle of the Blessed to save a dying Arthur, facing off against the primary antagonist, the sorceress Nimueh (Michelle Ryan). Main Characters and Cast
The season’s primary tension is established in the pilot episode, " The Dragon's Call
In Season 1, Morgana is not yet the villain she becomes. She is Uther’s ward, a fierce defender of the innocent who secretly despises her guardian’s cruelty. McGrath plays her as haunted and empathetic, struggling with prophetic nightmares—a clear sign that magic runs in her blood. The slow-burn tragedy of her character starts here.
Here, Merlin (Colin Morgan) and Arthur Pendragon (Bradley James) are peers—young men in their late teens. Arthur is the arrogant heir to the throne of Camelot, and Merlin is a powerless servant. This "Smallville-esque" approach (focusing on the heroes before they became legends) allowed the writers to explore the chemistry between two men who, according to destiny, should be enemies. Watching them bicker, prank one another, and eventually risk their lives for one another became the emotional core of the show.
