Varisia's newest heroes have stumbled across a powerful relic from the ancient empire of Thassilon - yet the artifact has been sundered into seven fragments. The third of these fragments lies in the swampy Mushfens south of the city of Magnimar, hidden within an ancient, towering lighthouse known as the Lady's Light. With squabbling boggards, troglodytes, and other swamp monsters dwelling in the region around the Light, approaching the ruins will require either stealth or bravado. But the threats posed by slimy and scaly humanoids pales in comparison to the exiled Gray Maidens who have claimed the interior of the Light as their new headquarters - or to the sinister curse that afflicts the powerful, ancient caretaker of the ruin. Continuing the Shattered Star Adventure Path, Curse of the Lady's Light is a Pathfinder Roleplaying Game adventure for 4th-level characters. This volume offers additional details on the Mushfens swamps of Varisia and a thorough investigation of the Gray Maidens. New monsters fill the Pathfinder Bestiary, while Bill Ward's Pathfinder Journal fiction explores the seedy underbelly of the scoundrel haven of Riddleport!
