System-neutral toolkit
Built to work across horror games and adaptable to the system already on your table.
The Conspiracy Engine
A system-neutral toolkit for crafting paranoia, corruption, and unseen power.
This book helps you build living conspiracies instead of fixed plots. It is designed for hidden organizations, compromised institutions, dangerous revelations, and campaigns where the web changes as soon as players start pulling on it.
Use it to create local secret societies, infiltrated agencies, occult networks, corrupt foundations, and slow-burn horror campaigns where trust erodes one decision at a time.
Living conspiracies
Create webs that adapt, fracture, conceal, and retaliate when threatened.
Quick or deep prep
Use fast-build tools for immediate play or dig into longer-form structures and examples.
Paranoia by design
Turn hidden power, moral compromise, and unstable trust into playable campaign pressure.
The point is not to reveal a master plan. It is to build a web of fear, ambition, and secrecy that keeps moving after the players touch it.
What this book does
The Conspiracy Engine gives game masters a framework for building conspiracy horror that feels alive. Instead of a single answer waiting at the end of an investigation, it helps you create structures that respond, hide, split, and deepen as the campaign unfolds.
Inside the toolkit
Power centers and actors
Build factions, institutions, agents, and organizations with motives, resources, masks, and vulnerabilities.
How the web holds together
Map influence, money, information, loyalty, and dependence moving between connected groups.
The public face
Give every conspiracy a believable exterior that hides what it is really doing underneath.
Revelations that complicate
Layer dangerous truths so every answer opens the story wider instead of closing it down.
Adaptive responses
Show how conspiracies react under pressure through schisms, panic, escalation, or retreat.
Tables, prompts, examples
Use templates, generators, quick-play resources, worksheets, and sample conspiracies to get moving fast.
What you can build
Local horror
Small-town societies, bloodline secrets, town archives, and personal betrayals.
Institutional corruption
Universities, councils, agencies, hospitals, and research fronts hiding deeper agendas.
Regional webs
Multiple organizations moving in parallel across cities, departments, and competing interests.
Global conspiracies
Ancient orders, sprawling occult systems, and unseen powers too large to fully map.
Who this is for
- Game masters who want conspiracies to feel reactive instead of scripted.
- Horror campaigns built on paranoia, corruption, secrecy, and unstable alliances.
- Referees who like modular tools more than fixed adventure paths.
- Tables that want investigation to lead to entanglement, not easy closure.
Best used for: investigative horror, occult thrillers, modern paranoia, secret societies, institutional corruption, and campaigns where every revelation makes trust harder to hold onto.
Build the web. Expose a secret. Watch the whole thing shift.
The Conspiracy Engine gives you a system-neutral toolkit for creating paranoia-driven horror campaigns built from hidden structures, dangerous secrets, and unseen power.
