Yesterday’s Merlin series 5 premiere was part one of two, and next Saturday we get the exciting conclusion to “Arthur’s Bane”! Watch the promo now.

In the first part of Merlin‘s returning episode, we returned to Camelot after a short period of time had passed, finding Arthur and Guinevere settling into their roles as King and Queen, while Morgana and Mordred plotted to once again take over and destroy Arthur’s reign.

In the second part, Arthur and Merlin find themselves alone in the icy tundra, closing in on the Ismere fortress.

The official episode description reads:

Merlin fears that the ancient prophecies about Mordred might come true as even he is not able to sway Arthur from his chosen path. Alone and close to exhaustion, Merlin and Arthur struggle to carry on as dawn breaks across the icy tundra. With each tortured step bringing them ever nearer to the looming fortress of Ismere, Merlin’s fear intensifies. What are Mordred’s real intentions? And what powerful secrets are Morgana and the druid Ruadan interested in finding amongst its twisted catacombs? It might be that this time not even Merlin can prevent Arthur from stepping right into the lion’s den… for only one thing seems certain in such bleak and transient wilderness: the great trial for Albion has finally begun.
