Camelot basks in the halcyon days of a new golden age. But even as she flowers, so the dark seeds of her destruction are being sown... For in the frozen wastelands of the north, men are disappearing without trace.
In search of answers, King Arthur and his knights must undertake a dangerous mission to the unknown. As the sun sets on the icy plains, Merlin finds himself locked in a battle unlike any he has fought before; a battle with fate itself.
