Darkness descends upon the land and threatens all the High King has battled to save.

At the dawn of his reign, a young king must prove his greatness … or forfeit a realm.

Arthur is King—but darkest evil has descended upon Britain’s shores in many guises. In this black time of plague and pestilence, Arthur’s most trusted counselor Myrddin — the warrior, bard, and kingmaker whom legend will name Merlin—is himself to be tested on a mystical journey through his own extraordinary past. So the noble king must stand alone against a great and terrible adversary. For only thus can he truly win immortality—and the name he will treasure above all others: Pendragon.
