The Dreamlands Have Never Been Stranger. Following on from the success of Bookhounds of London comes this comprehensive campaign guide for Trail of Cthulhu. Recreate the mundane and mystical adventures of the Parisian surrealists, from the 1920s to the coming of the Occupation as they stumble onto the Dreamlands, a fantastical realm found far beyond the wall of sleep. At first by happenstance and later by implacable design, they can remake the Dreamlands in the fiery image of their own art. Will they save the world, or destroy it?
