Corrected entry: If people who are magic are persecuted and killed throughout Camelot, why don't they use their magic to prevent getting caught in the first place? Merlin can move things with his mind, so all the other magicians should be able to do that as well to avoid capture.
Factual error: In the show Gaius wears glasses, except eyeglasses first came into use in the late 13th century while the legend of King Arthur is around the 5th or 6th century.
Correction: There are different types of magic used in the show, so not all magic people have the ability to move things.
