Within its borders, there are routes to unknown places, great secrets, shrines to long-dead gods, and monsters the like of which have never been seen on the surface world. In the Heart RPG, players take on the role of delvers – strange, desperate, broken people exploring the nightmare city in search of the object of their obsessions.

Take your first steps into the City Beneath with this streamlined version of the rules for the Heart RPG. This document includes:
