After a terrible war, medieval England is under the watchful eye of The Guild, formed centuries past to ensure that society has a chance to rebuild slowly and safely. Adept at playing many roles, its powerful Guildsmen - at times warriors, wizards or spies - serve as judges and executioners to protect the fragile society.Their plans are thrown into turmoil by an invading force that no-one saw coming...a Japanese fleet, bringing with it fanatical samurai, deadly ninjas and powerful sorcerers. Worse, they have managed to awaken their long-dead heroes, including the Miyamoto Musashi, Japan's greatest swordsman, and the fearsome Winter Dragon.Unable to stop the initial Japanese attacks, the Guild recalls some of England's own dead heroes: William the Conqueror, Merlin and Robin Hood joining the fight against the invaders. Arden and Carron, two of the Guild's finest, are forced by the Guild Council to sit back and watch as the invaders spread across England. As the situation becomes more desperate, and the old English heroes fall, the two friends are forced into the forefront of the war, taking command in one last stand that they hope will break the invading armies once and for all.
