The Great Dragon is finally free and sets out to destroy Camelot, full of rage. Arthur and his men cannot stand the battle for much longer, and Merlin's powers are useless. Only a dragonlord can kill a dragon, and Uther wiped them all out years ago. However, Gaius admits one such Dragonlord escaped. Balinor is the key to the future of Camelot, but it will be up to Arthur and Merlin to find him.
