The Enemy Within is a five-part campaign for Warhammer Fantasy Roleplay. It originally consisted of six adventures, which have been re-printed into five new books.
1. Enemy in Shadows (formerly The Enemy Within & Shadows over Bogenhafen)
2. Death on the Reik (formerly same name)
3. Power Behind the Throne (formerly same name)
4. The Rat King (formerly Something Rotten in Kislev)
5. Empire in Ruins (reprinted as Empire in Flames)
It is set within the Empire of the Warhammer Fantasy Setting, and involves the players uncovering a conspiracy against the Empire.
This version of the game is set in an alternative version of the Holy Roman Empire in Europe in 1702, during the start of the War of Spanish Succession. It uses the technology of that time period, but also incorporates magic and certain elements of fantasy.
It also substitues real-world religions, Protestant, Catholic, Muslim etc, for the religions and the Chaos Cults are replaced by Devil-Worshippers.
The campaign is a little tongue in cheek and pokes fun at the religious and social prejudices of the time, while maintaining a serious and dangerous edge.
So far, parts 1-3 of the campaign have been run. The Rat King would be next, but that story will need a lot of changes to fit into my campaign.
