[Movie] Merlin (S5E12) The Diamond of the Day – Part 1
Synopsis: Morgana succeeds in stripping Merlin of his power. With their greatest enemy now powerless, Morgana and Mordred, with their Saxon army, begin their offensive against Camelot by attacking a nearby garrison. Arthur sees Morgana’s actions as an act of war and decides to meet her forces at Camlann to prevent her from ever reaching Camelot. Morgana forges a sword for Mordred in Aithusa’s breath, confident that nothing can survive its touch. Merlin prepares to journey to the Crystal Cave to get back his powers; however, Morgana finds out about his plans through her use of a spy. Morgana and Merlin come face to face in the cave and the High Priestess traps Merlin in the cave forever. At Camlann, Arthur’s and Morgana’s armies come face to face with one another and the final battle begins. Morgana watches from a cliff as Arthur and his men desperately fight against the Saxons and Mordred ruthlessly kills knights with his new sword. At the crystal cave, with the help of a vision of his father Balinor, Merlin, as Emrys, makes his way out of the cave and straight for Camlann; his moment of destiny to save Arthur and Albion from Morgana has finally come.
