Merlin

New servant Cedric muscles in on Merlin's position as Arthur's right-hand man, and turns the prince against his loyal friend. Merlin is convinced the slippery newcomer is up to something.

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's nightmares spill into waking hours, she becomes terrified that she has magic. Gaius is determined to keep her in the dark for her own good but Merlin won't stand by and watch his friend suffer.

Gwen is mistaken for Morgana and kidnapped by the savage outlaw Hengist. Uther refuses to pay her ransom, so Arthur defies his father and heads out into dangerous enemy territory to fight for Gwen's freedom.

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. As her true troll nature surfaces, her influence over Uther increases, and the repercussions are felt throughout the kingdom.

Uther is determined to wipe out magic in Camelot once and for all so he summons the most dreaded witchfinder in the land, Aredian, 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 saves a Druid girl from a bounty hunter's cage, but there is more to her than meets the eye.

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.

Uther has a precious magical relic of the Old Religion locked up tight in the Camelot vaults. Many have lost their lives trying to reclaim the Crystal of Neahtid, but the ruthless warlock Alvarr could succeed where they failed.

When the Fires of Idirsholas burn for the first time in 300 years, Gaius fears a sorcerer has revived the deadly Knights of Medhir.

The Great Dragon is finally free. Full of rage, he attacks Camelot with pitiless intensity. The castle is crumbling and Arthur's men cannot hold out much longer but only a Dragonlord can kill a dragon and Uther wiped them all out years ago, or did he?
