This is a non-profit, fan-made series of submods (or mod mods) for Geheimnisnacht, an unofficial Warhammer Fantasy conversion mod for Crusader Kings II. The project is not a standalone mod, but seeks to add options for players. The project logo is the work of the excellent CMSteel (search for the artist on DeviantArt if you want to see the original). "Warhammer" is a trademark of Games Workshop and no challenge to their commercial rights is intended by this work.
Here's another screenshot for the Engineers, showing their usefulness in building up your holdings. They also have a "steamier" power, but you'll have to try Dawi Kiss to find out about that.
