From the back cover: The Perilous Forest supplement includes three major adventures, and extensive background for western Cumbria and the Perilous Forest. These adventures are arranged as a linked campaign along the King's Highway from Eburacum to Carduel. They can be played individually without adjustment. Player handouts are provided, as are a detailed map of western Cumbria and another of Hadrian's wall, showing cities, wall conditions, and other notes for the time of Arthur.
