Dagger in the Heart is the first hardback sourcebook for Heart: The City Beneath. This new 144-page release is dripping with evocative prose from author Gareth Ryder- Hanrahan, grotesque full-colour illustrations by Sar Cousins, and immersive layout by ENnie award-winning Mina McJanda.

Inside you can find a sandbox adventure that takes Delvers into the deepest recesses of the Heart in search of their destiny. You are caught in the wake of the Delving Machine: a device that bores through rock, blood, bone, space, time and reality, towards the scintillating terror of a crimson eternity. As your journey progresses, you doomed delvers will encounter a trio of antagonists who each seek control of the machine to shape their ideal future: the arms dealer Ptolemy Bay, the aelfir politician Aramos, and The One Who Waits In Ashes, a ragged figure who appears all too familiar.

You'll witness the dreadful impact of Zenith abilities your Zenith abilities on the places that they journey through. You'll venture via uncanny passages to Summersisle, home of the humans, on the eve of their greatest tragedy. Ultimately, if you survive long enough, you might just stand before the Heart itself
