A burial place of one very rich man is found in the dark depths of citadel and Gaius believes this man was very powerful in ancient time and identifies him as a mighty magician of ancient times. The found tomb belongs to Cornelius Sigan who used the stone to hide his soul there so that it would live forever. But this magic and powerful stone is gone together with the soul inside and now belongs to a thief known as Cedric. Merlin will soon have to fight the very powerful magician because as soon as Cedric touched the stone, Cornelius’s soul escaped it and moved into Cedric’s body. Some worries come from the side of Arthur who starts to doubt his powers, particularly the fighting skills.
