A person who dares to swear by the Rune Staff will inevitably change his own fate, as well as the fate of his world. Throughout the history of the Runestaff there have been many such oaths, but none of them have brought as much grief and disaster as the terrible oath of vengeance of Baron Meliadus of Croyden. It was then that Dorian Hawkmoon, Duke of Cologne, found himself drawn into a dangerous confrontation between the forces of Order and Chaos, lost his beloved woman, the legacy of his ancestors, his freedom. But in the Multiverse of Michael Moorcock, having been defeated in one of the worlds, the Eternal Hero is able to win in a parallel dimension, regain what was lost, find hope.
