| For years, the knights of Mendev have held back the evil locked inside the Worldwound, a vast, demon-tainted landscape. Every few years, they anoint a new protector, a sacred guardian charged with pitting his will against the teeming hordes bent on devouring the very souls of the living. This year, something has gone horribly wrong, and now a bloodthirsty demonic army has overrun the ancient fortress, and threatens to pour into the surrounding countryside.
The Demon Within is a dungeon-based adventure for 11th-level characters compatible with the world's most popular fantasy roleplaying game. This adventure includes all the information you need to send your heroes into the belly of a demon-infested keep littered with lone survivors, desperate holdouts, and fallen heroes.
