Build your home in the darkness, then watch it fall. Sanctum expands the Heart RPG with comprehensive rules for establishing settlements in the perilous City Beneath—creating the perfect foundation for your next campaign.

This sourcebook guides you through creating havens with your group, managing haven-based adventures, and dealing with unique fallout that reflects your settlement's struggles. Develop meaningful connections with the inhabitants as you work together to survive the Heart's dangers.

But beware—the Heart has noticed your sanctuary. Inside you'll discover four new types of angels, the terrifying messengers of the Heart Itself that infiltrate and demolish havens. Read through the paranoid theories of washed-up author Gris Hannemann who may have accidentally made them real through his writings.

With Sanctum, you'll:

• Construct unique, doomed settlements threatened by dangers from inside and out
• Defend your community and strive to help its residents survive and thrive
• Face the inevitable moment when the Heart sends its messengers to tear everything apart

Every haven tells a story—of community, resistance, and ultimately, beautiful tragedy.

Note: Requires the Heart: The City Beneath core rulebook to play.
