This unofficial supplement contains one organisation, four landmarks, six fallout options specific to two of the landmarks and several plot hooks for you to use in your game of Heart: The City Beneath. 

  • The Order of Sanguine Sorcerers, a group who believe that you can use the flow of your own blood to map the Heart, and their headquarters Sacracordia
  • The Super Wonder Gallery, a cursed place of creation where physical manifestations of art take on lives of their own
  • The Galactic Cake, an endless landscape of stars where you can walk from point to point to create your own constellations
  • The Stables, a mysterious and ghostly tableau of a moment in time where everything in the universe is stable

CORPUS is an unofficial supplement for Heart: The City Beneath by Rowan, Rook and Decard. It is not a standalone game and requires a copy of Heart: The City Beneath to play.

Heart: The City Beneath is the property of Rowan, Rook and Decard. No copyright infringement is intended. CORPUS is not endorsed by or affiliated with Rowan, Rook and Decard. 

Content warnings: Heart: The City Beneath is a horror game and this supplement is written in the same vein. It contains self-injury, disembowelment, body horror, suicide, and ghosts.

Please let me know if you use any of these ideas in your game! I'd love to hear about how it went.

I love Heart and the landmarks here gave me some fresh inspiration. They're all so varied yet fit the Heart wonderfully!

Wow, thank you so much! I’m really glad you like them! This is the first time I’ve written anything for Heart and I had a lot of fun with it. Thanks again for reading; I hope you enjoy your game!
