Doom of the Savage Kings (Dungeon Crawl Classics #66.5)

High above the windswept moors and darksome woods, the village of Hirot is under siege. Each night, as the sun sinks beneath the western mountains and the candles burn low, a devil-beast stalks the village streets, unleashing its savage fury on the living. From warlord to pauper, crone to child, no one is safe.
