The Darkest House

The Darkest House is a system-agnostic horror mega-adventure designed to enter the campaign you're already playing, regardless of setting or RPG system. The House that Hungers can take root in virtually any world, drawing on characters' memories, fears, relationships, and moral choices as they explore its many rooms and try to escape.

This 296-page hardcover is built for immersive, GM-friendly play. Rooms are presented as two-page spreads, with downloadable player-facing maps, illustrations, handouts, and sound files available through shortlinks and QR codes. The House System provides simple rules for bringing characters from other RPG systems into the adventure and returning them to their original game afterward.
