Young Merlin is a teenager, discovering and then learning to master his magical gift. Magister Gaius, King Uther Pendragon's learned court physician to whom he's assigned as humble page, teaches him medicine, coaches his magical self-study, and warns him of Uther's strong aversion to magic. Merlin becomes squire to the noble but imprudent crown prince, Arthur, whose fate is linked with Merlin.

Constantly throughout the show we see mail clad knights being injured or killed by slashes from a sword. It's nearly impossible for a sword to penetrate chain mail and cause anything more than a bruise or broken bone, especially when slashed with the swords they're using. Even a very hard thrust with a sword against mail would have minimal effect. They might be able to break a few links with a very hard slash, but would never get through it all the way to the body.
