Under the Shadow explores one rough-and-tumble port city in the world of Midnight that beats the dark lord of Eredane at his own game: Baden's Bluff, the center of an underground resistance for all foes of evil. This sourcebook contains dozens of organizations, NPCs and location descriptions for the city of Baden's Bluff, maps, adventure hooks, and local rumors to incorporate into any Midnight campaign, new feats, prestige classes, charms, and equipment for eluding the hunters of the dark lord and fighting the tyrants of the shadow using more subtle, but no less heroic, methods.
