Core Mechanic

Roll 2d6 and spend Darkness Tokens (up to 3) to add to the result instead of a fixed stat modifier. 7 or less is a miss, 8–10 is a complete hit, and 11+ is a catastrophic success — you achieve your goal but your monstrous power causes collateral damage. Bonds with other characters add +1 or −1. Darkness Tokens accumulate through roleplaying triggers specific to each playbook; exceeding 5 tokens forces a crisis that costs either a Bond or advances your Ruin track toward becoming a Harbinger of the apocalypse.

Best For

Groups who want emotionally intense, mystery-driven play as monstrous agents investigating apocalyptic threats — where the real tension comes from relationships and the risk of losing yourself to your own power.

Highlights

Darkness Token economy replaces static stats with a dynamic risk/reward resource that escalates tension throughout play. Catastrophic success mechanic means the strongest rolls carry the most dangerous consequences. Seven playbooks built around emotional wounds rather than combat archetypes. Five pre-assembled mysteries plus detailed guidance for creating custom ones.

Considerations

Requires buy-in for emotionally vulnerable roleplay — characters are designed to hurt and be hurt. No tactical combat system; conflict resolution is narrative. Mysteries have no pre-written solutions, which demands improvisational confidence from the Keeper. Mature themes including body horror, mind control, and moral degradation are baked into the core premise.
