Dark horror stalks the streets of Carrion Hill, the strangest and most debased city in the star-crossed gothic horror kingdom of Ustalav. Following the once-forgotten instructions of an ancient eldritch ritual, a cabal of villains conjured up a creature of terrible power in the ruined catacombs of the city. Putting a stop to the abomination means dealing with the cabal one by one, from its weakest devotee to its most potent dark master. A dark urban horror adventure for 5th-level Pathfinder Roleplaying Game characters, Carrion Hill brings Lovecraftian horror to the game table and irreparable psychic damage to your player characters.
