The Western Alliance
A fan-made gazetteer for the Mystara campaign setting, this volume details the Western Alliance and its connections to Wendar, Denagoth, the Northern Wildlands, and Ghyr. It presents the region’s history, peoples, kingdoms, and threats, with a setting shaped by tall tales, mischievous gnomes, brooding giants, and emerging nations. An “Idrisian Grimoire” addresses additional questions from the preceding gazetteers and provides material for incorporating the region into campaigns.
