Aglain (portrayed by Colin Salmon) was a Druid man who lived in the Forest of Acestir. In the second season episode, "The Nightmare Begins", he, with the assistance of Mordred, rescued Morgana from a group of serkets, and later healed the injury she sustained from one of the creatures. While she resided with him and his fellow Druids, Aglaia encouraged Morgana not to fear herself and her emerging abilities, telling her that magic was not evil and not something Uther should hate. When Arthur and his knights arrived in pursuit of Morgana, whom they thought had been kidnapped by the Druids, Aglain tried to help Morgana and Mordred flee with his people. However, in the process, he was shot dead by one of Arthur's men.
