Speaking to French TV magazine Séries Mag, Morgan commented: “The action takes place a few years after Series 4. I can also confirm the return of Mordred, but he’ll now be played by an older actor named Alexander Vlahos. Anyone familiar with Arthurian legend knows that Mordred plays a central role in the fall of Camelot. His presence is not a good omen for the kingdom.”

The actor also teased: “Dragons will be at the heart of the action, because Merlin and Morgana now derive their powers of these magical creatures. Their next battle should be epic. Morgana could outmaneuver him this time…”

Morgan has also revealed that he believes “it’s time that Arthur learns the truth”.

Do you think it’s time for Arthur to discover the truth? Let us know below…
