Full Episode Summary
In the dark tunnels beneath Camelot an ancient tomb is discovered, filled with treasure. Gaius begs the King to seal it shut again, fearing the tomb belongs to Cornelius Sigan, an evil sorcerer who cursed Camelot and swore to one day return and destroy the city. But Uther is too taken with the treasure to listen, insisting Sigan is just a fairytale.
Meanwhile, new servant Cedric muscles in on Merlin's position as Arthur's right-hand man and turns the prince against his loyal friend. Merlin is convinced the slippery newcomer is up to something and he's right: Cedric is a conman and a thief who's after the magnificent jewel found at the heart of the tomb. Little does Cedric know, his precious prize is more dangerous than he could possibly imagine.
Camelot has never been more vulnerable but how can Merlin make things right when, thanks to Cedric, he might have lost Arthur's friendship for good? Merlin faces the prospect of turning to the creature he swore he'd never trust again: The Great Dragon.moreless
