Merlin - Season 3

Merlin and Arthur have been on many quests in search of the missing Lady Morgana. The despondent Prince is all but ready to give up. But as they recover from their latest skirmish, a bruised, bloodied figure emerges from the mist... it is the Lady Morgana.

King Uther is overjoyed, but then starts to lose his mind. Merlin thinks that magic is the cause; could this be the work of his dutiful ward? The young warlock puts himself in grave danger trying to find out whose side Morgana is really on.

With Merlin gravely ill from the Serket's poison, Morgana and Morgause continue with their evil plan. They have mentally incapacitated Uther and convinced his enemy, Cenred, to invade Camelot. The fate of the kingdom now rests on Arthur's shoulders.

The Prince and his Knights resist the invaders, but Cenred's soldiers are not the only threat they face. Can Merlin stop Morgana in time to save Arthur from the enemy within?

Merlin stumbles across a secret chamber and accidentally releases a Goblin. The mischievous creature possesses Gaius, leading the once-wise physician to develop a taste for gold, ale and magical jokes.

With a suddenly-bald King and a scourge of flatulence sweeping the royal household, can Merlin work out what is going on and banish the Goblin back to where he came from before any real damage is done?

When Merlin and Arthur find themselves vastly outnumbered in a tavern brawl, an enigmatic man helps them to victory. The stranger risks his life to protect the prince, and is seriously wounded in the process.

Arthur takes him back to Camelot, where he quickly sets about drinking, charming the ladies, and causing trouble for Merlin. But when what appear to be two unscrupulous Knights try to kill the Prince, can Merlin and the inscrutable stranger save the day?

When Merlin has an unexpected meeting with the mysterious Taliesin, the wizened old sorcerer takes the young warlock to the crystal cave and shows him a glimpse of the future. But this gift turns out to be more of a curse when, to his horror, Merlin sees Morgana, set to kill Uther.

Merlin knows he must do all that he can to stop the future from playing out. But changing the pages of destiny is a dangerous game, and his actions have fatal consequences. With the whole of Camelot in a state of grief, can the young warlock undo the damage he has caused, or is it too late?

Arthur is pressured into an arranged marriage with a visiting princess, Elena. Merlin's reservations are vindicated when he discovers Elena may not be exactly who she claims to be. Whilst trying to uncover the dark secret hidden inside her, Merlin learns that Elena's nanny is a pixie. But who is she working for? And what do they have to gain from this marriage? Can Merlin get to the bottom of this mystery before Arthur makes the biggest mistake of his life?

Gwen finds herself with an impossible dilemma when she is forced to choose between Arthur and her estranged brother, Elyan. With one of them certain to die at Cenred's hand, who will Gwen choose? The love of her life, or her only sibling?

Loyalties are tested to the limit and friendships are thrown to the fore as Arthur, Merlin and Gwen work together to try and find a way out of the situation. But with Morgana and Morgause doing all that they can to scupper the threesome's plan, can good conquer evil, or will Gwen lose another of those she loves?

Arthur embarks on a solitary quest to retrieve the Golden Trident from the Fisher King and prove himself worthy of the Camelot throne. With the Prince beyond the protection of the citadel, Morgana sees an opportunity to use her dark magic and gives him a precious bracelet containing a Phoenix Eye. She insists he wears it at all times for protection, but it saps him of his life force and he is left defenceless in the Fisher King's perilous realm. With the help of Gwaine, can Merlin reach him in time and fulfil his own quest to protect the future king of Camelot?

When an old flame of Gaius's arrives in Camelot, Merlin is pleased to see a different side to his curmudgeonly mentor. But after discovering she is under the influence of a Manticore, a creature from the Old Religion, Merlin has no choice but to tell his old friend of Alice's evil intentions.

Morgana is tormented by dreams of Guinevere becoming Queen of Camelot. Encouraged by Morgause, she decides to reveal Arthur and Gwen's courtship to Uther, who will do whatever it takes to stop his son from marrying a serving girl.

The only rule in Camelot's legendary tournament is that there are no rules. The mythic city fills with terrifying warriors and are joined by Gilli, who despite his small stature has victory in his sights and a secret weapon to help him - magic.

Merlin and Arthur are sent on a dangerous mission to capture the Cup of Life, a powerful magical artifact that carries the gift of immortality. Before they can retrieve the Cup, they are captured by the unscrupulous slave trader, Jarl.

Queen Morgana begins a reign of terrible evil over the innocent citizens of Camelot. With Morgause's immortal army at her command, it seems there is no hope for Uther, who must watch his Kingdom crumble under the unimaginable cruelty of his own daughter.
