The Inverted Pyramid - digital version

The Inverted Pyramid 

A descent into geometry, faith, and rot.

This book is not a normal adventure. It's a machine for unmaking your players. Drop it into a campaign, any system - a doorway, a dream, a wrong reflection - and watch as the world folds inward. Each room a choice, each choice a wound. Inside 100 chambers of body horror, confusion, and inevitability; a healer who trades in blood and teeth; and an architect whose design refuses to let him die.

The Pyramid always remembers.

A system agnostic TTRPG supplement heavily inspired by Mörk Borg, with a dash of insanity and The Cube movie series.
