Characters
Merlin
The series protagonist is a young, remarkably talented sorcerer who attempts to keep his powers secret and will one day become the greatest wizard in the world. He is also Arthur's friend, despite the initial animosity between the two.
Arthur Pendragon
The headstrong, arrogant and reckless but kind and benevolent son of King Uther, and future King of Camelot. Merlin must protect him from harm. Arthur becomes friends with Merlin, and the pair have saved one another's lives on numerous occasions.
Morgana
King Uther's ward and the daughter of his late best friend. Morgana is best friends with Gwen despite their class differences and is also secretly a "seer" - a person who has prophetic powers.
Gwen
Morgana's humble maid servant, and her friend. She has an open, friendly personality but is occasionally antagonistic with Arthur.
Uther Pendragon
Arthur's father and current king of Camelot. Uther is depicted as a ruthless and sometimes cruel man, but he cares deeply about his subjects and friends. However, he is frequently blinded by his hatred for all forms of magic.
Gaius
Camelot's court physician and one of the few who know Merlin's secret. Gaius used to be a sorcerer himself, and is something of an alchemist and magical scholar. He has a dry sense of humour and sees Merlin as the son he never had.
The Great Dragon
Merlin often visits the Dragon when in a predicament, because the Dragon claims he knows Merlin's destiny. The Dragon is also one of the few who know Merlin's secret. The Dragon appears omniscient at times, and his motivations are unknown beyond his desire to be released from the dungeons of Camelot.
Nimueh
The main antagonist of the first series, Nimueh is here portrayed as a beautiful, powerful, but amoral sorceress, bent on overthrowing Uther and Arthur and restoring magic to Camelot.
