The Sword in the Stone

''"Taking Camelot was the easy part, Helios. I want Arthur." –''Morgana

The Sword in the Stone comprises the twelfth and thirteenth episodes of the fourth series of Merlin and is the two-part finale.

Part One
With Morgana at the helm of a vast Southron army, a deadly net is closing in around Camelot. When the sorceress strikes, the ferocity of her attack forces everyone to run for their lives - even Arthur. But Morgana will not let him escape that easily. And so begins a chilling hunt...

Can Merlin save the King from Morgana's clutches? Or has Arthur's luck finally run out?

Part Two
thumb|300px|rightMorgana and Helios have successfully captured Camelot, and Merlin and Arthur are outlaws on the run. Trapped in Ealdor with a ruthless army closing in, their situation becomes desperate. Arthur must take control before Camelot is lost forever, but faced with Agravaine's betrayal and the strength of Morgana's force, the young King has lost his conviction.

Only Merlin can restore his faith, and only an extraordinary act can prove to the King that he was born to rule. Will the young warlock convince Arthur before his dreams of Albion fall to pieces?
