Warhammer Fantasy Middenheim - City of the White Wolf

Middenheim: City of the White Wolf distils the best of previous writing on the chosen city of Ulric, and combines it with new creatures, new NPCs, new locations, and rules to create the ultimate sourcebook for groups wishing to adventure in Middenheim and its surrounds. Full rules for creating Middenheimer, Middenlander and Nordlander Characters are included, along with a new career for true devotees of Ulric. 

A stand-alone book, Middenheim: City of the White Wolf also makes an excellent supplement for those intending to run Power Behind the Throne, part three of The Enemy Within campaign. While the companion content is very focused on the events of Power Behind the Throne, this book provides more details on the city for GMs who are happy to let their groups explore more widely. It details Middenheim around 2512 IC, prior to the events of The Enemy Within, but includes an appendix with updates on how future events are set to alter the city.
