The Merlin episode “The Disir” just finished airing, and here’s the promo for next week’s episode “The Dark Tower”!

What did you think about “The Disir”?! We definitely thought that the Disir themselves made for a terrific enemy against Camelot, and it was great to finally focus more on Mordred and see a hint as to the role he’ll play in the story.

Next up, we’re going to see more of Gwen and Morgana as the old friends reunite – sadly in a less happy way than it sounds. In “The Dark Tower,” Morgana will kidnap Queen Guinevere in a bid to lure Arthur into a trap, oh no!

The official description released by the BBC reads:

When Gwen is snatched from Camelot without warning, Merlin knows there can be only one person responsible: Morgana. Arthur is determined to rescue his queen, but it will not be easy; she is locked in the Dark Tower, a place that haunts the dreams of men…

Arthur and his knights must embark on a quest like no other, battling through a landscape riddled with hidden dangers, perilous obstacles and magical beings. As they near their goal, Merlin’s sense of dread reaches breaking point. What twisted game is Morgana playing? And more importantly, just what is the final test that awaits them in the tower?

Merlin 5×06 “The Dark Tower” will air next Saturday on BBC One. Note the earlier time of 20:05 GMT.
