The Diamond of the Day

"I want him dead!"

- Morgana Pendragon

The Diamond of the Day is the two-part finale of the fifth series that consists of the twelfth and thirteenth episodes; the final two episodes of Merlin.

Part One
High in the mountains, a great horde gathers; Morgana prepares for war with a vengeful Mordred at her side. Merlin feels the weight of his destiny like never before as the ancient prophecies play out with terrifying accuracy. But before he can save his beloved Camelot, he must save himself. For it is not just the kingdom Morgana wishes to destroy – it is also Emrys. Do not miss this penultimate episode in the epic final series of Merlin.

Part Two
And so it seems the Prophets did not lie. As the great battle rages on Camlann's mighty plain, Merlin faces his moment of destiny. Can he find the strength to save the man he made a King; the Camelot they fought to build; and the brotherhood they shared?
