AD 375. As Rome’s legions abandon their forts, chaos grows on the fringes of Britannia. In the far west, the shattered forces of the House of Pendragon huddle together in order to protect the royal heir – their one beacon of hope. For Lucanus, their great war leader, is missing, presumed dead. And the people are abandoning them. For in this time of crisis, a challenger has arisen, a False King with an army swollen by a horde of bloody-thirsty barbarians desperate for vengeance. One slim hope remains for Lucanus’ band of warrior-allies, the Grim Wolves. Guided by the druid, Myrrdin, they go in search of a great treasure – a vessel that is supposedly a gift from the gods.
