Merlin

Deep beneath Camelot an ancient evil stirs and Merlin must risk his very soul to save the kingdom from destruction.

Merlin helps Arthur disguise his identity to enter a jousting tournament, little knowing that a deadly assassin has arrived in Camelot to kill the Prince.

When Morgana begins to fear she might have magic, Merlin puts both their lives at risk to get her the help she needs.

Gwen is mistaken for Morgana and kidnapped by the savage outlaw Hengist.

Uther is captivated by his latest guest, the beautiful Lady Catrina. Arthur is appalled by his father's flirting, but Merlin is wary for a different reason - he suspects she is really a troll!

Newly crowned Queen Catrina settles in as Camelot's first lady.

Uther is determined to wipe out magic in Camelot once and for all, and this time no one is beyond suspicion. He summons the most dreaded witchfinder in the land, Aredian (Charles Dance), a terrifying man who will stop at nothing to uncover sorcery.

When a mysterious warrior challenges Arthur to a duel, no one could possibly predict the devastating chain of events that is set in motion - least of all the young Prince himself.

Merlin meets a kindred spirit but his new friendship is threatened when a deadly magical beast attacks Camelot.

Dignitaries from rival kingdoms descend on Camelot for peace talks, but what King Alined really wants is war and he'll do everything in his power to stir up hostilities, even if it means using magic.
