from the introduction:
This gazetteer contains notes on the small town of Zipf in northeast Stirland and the fief in which it is located, the Leithag mark. The article is inspired by (and hopefully consistent with) works of – Alfred Nuñez Jr (notably his gazetteers and maps) and Natascha Chrobok’s excellent Monasteries of the Old World, as well as Sigmar’s Heirs by Black Industries/Green Ronin.
As there are plenty of plot hooks in both Liber Fanatica III and the GM’s Toolkit by Black Industries/Green Ronin I have not included any in this article.
This supplement details a town in Stirland. Although the introduction mentions several WFRP2 supplements the material is purely descriptive and references no particular edition.
