Episodes
Morgana takes the dying Morgause to the Isle of the Blessed where she unwittingly tears the veil to the spirit world, unleashing the Dorocha, invisible ghosts that begin to attack the kingdom. At Camelot, where a weakened Uther has given over much of his rule to his scheming brother-in-law Agravaine, Merlin senses what is happening but finds his magic inadequate to stop it. As Camelot fills with refugees, Gaius reasons that, as one death opened the portal, only another will close it. Arthur offers himself as the sacrifice and travels to the Isle of the Blessed with Merlin and a group of young knights. Here, after Arthur has finally praised him for his bravery, Merlin appears to have a fatal encounter with one of the Dorocha.
The kingdom is on the brink of collapse, with Morgana poised to strike. As Lancelot races back to Camelot with the dying Merlin, Arthur must continue on his mission to vanquish the Dorocha without them. Though the knights know their journey to the Isle of the Blessed is fraught with danger, none anticipate the sacrifice Arthur intends to make there. Friendship and loyalty are tested to the limit, but in the end, it is the power of love that changes all their lives forever.
The mighty citadel is buzzing in anticipation of the prince's birthday celebrations, but Arthur's old adversary, Odin, promises to ensure this is one party Camelot will never forget, for amongst the assembling guests lurks a deadly assassin, set to strike. As the dust settles, Camelot is left devastated, but just how far is Merlin prepared to go to put things right? Would he really risk everything and reveal his secret?
The mysterious Julius Borden arrives in Camelot with news of a magical secret that threatens to change the landscape of the kingdom forever. He has located the final part of the key to the tomb of Ashkanar, an ancient mausoleum which holds a very special treasure: the last remaining dragon's egg. Merlin is understandably drawn in by Borden's news, and promises to help him, but just who is the enigmatic stranger and, more importantly, what does he really want with the egg?
Arthur faces his first true test as King when he incurs the wrath of the formidable Queen Annis. With the lives of thousands hanging in the balance, Arthur must find the strength to be his own man and become the leader Camelot so desperately needs.
These are the brand new adventures of Merlin, the legendary sorcerer as a young man, when he was just a servant to young Prince Arthur on the royal court of Camelot, who has soon become his best friend, and turned Arthur into a great king and a legend.
