From the back cover of the 1987 Games Workshop boxed edition:
On the surface Bogenhafen is just another bustling market town; the annual fair and market of the Schaffenfest is in full swing, and the adventurers are among many others flocking to the town.
But all is not as it seems. From the happy bustle of the fair, the adventurers find themselves drawn into a deadly web of intrigue, uncovering evidence of a sinister secret organization whose tentacles run through the highest levels of the town's society. They must tread carefully, sorting the guilty from the innocent, the misguided and the deceived, able to trust no one in a deadly game of hide-and-seek where nothing and no one is quite as it appears.
Can the adventurers save Bogenhafen? Can they save themselves from the misguided zeal of the authorities? And can they reach the heart of the canker before it is too late? All the time, the society and its pawns are watching, trying to misdirect and thwart the adventurers, trying to buy time - for the consummation of its evil plan draws ever closer...
Shadows Over Bögenhafen is the first major adventure for Warhammer Fantasy Roleplay, intended for beginning-level characters.
From the back cover of the 1995 Hogshead Publishing softcover edition:
The Enemy Within: Shadows Over Bögenhafen is the first volume in an epic campaign for Warhammer Fantasy Roleplay. It is the definitive guide to the mighty Empire of the Warhammer Old World, full of background information covering the history, geography, politics and religions of the Empire, as well as invaluable material on starting and running the campaign.
And you can begin straight away with an intriguing and chilling adventure which introduces the players to the Empire, sets them on a hunt to seek out and destroy the heart of a demonic conspiracy, and brings them face to face with the corruption threatening the very foundations of their world. This volume combines material originally published separately as The Enemy Within and Shadows Over Bogenhafen, now revised into a clearer, easier to use format.
