## Plot

After three years of peace and harmony, Camelot's future could not appear brighter. But as Merlin helps King Arthur to bring the kingdom into a Golden Age, the seeds of Camelot's destruction are being sown as the sorceress Morgana Pendragon resumes plotting Arthur's downfall.
When an old face returns to the castle and gains a position amongst the king's inner circle, Merlin must be on guard more than ever. For the new arrival is the sorcerer Mordred, the Druid boy whose destiny it is to end the King's life and bring chaos to Camelot; after all, Merlin has been warned in the past that Mordred is destined to unite with the evil Morgana in a deadly alliance which will destroy Camelot. With the death song of King Uther haunting the castle, Morgana's powers greater and more dangerous than ever and Guinevere crossing over to the dark side, both Merlin and Arthur find that their destinies are approaching. The battle for Camelot is headed for a deadly conclusion and nothing will ever be the same again.
