King Uther Pendragon

King Uther Pendragon is the father to Arthur and Morgana Pendragon. He is the king of Camalot, and is known for his hatred for magic as well as his many victories on the battle field. He is quite cold hearted, but when Morgana betrayed him, he completely lost his mind.

He died at the start of the 4th series, due to Morganas meddling, and Merlin (who was disguised as an old man) Took the blame from Arthur.

In the 5th series, Uther comes back as a ghost. He tells Arthur that he is disappointed in him and that he is no longer his son, because he let peasants become knights and he married a servant girl.

Arthur and Merlin are trying to get the ghost Uther into a magic horn, and they split up trying to find him.Merlin finds him first and reveals that he has magic to Uther, who rages and goes on about how there was evil at the heart of Camelot. Arthur comes into the room, and just as Uther is about to tell him Merlins secret, they get him back into the magic horn.
