What Is Black Margin?

Black Margin is a science-fiction cosmic horror tabletop roleplaying game set in the year 2190. It is a hard and bleak science fiction setting where corporations dominate human civilization, manufactured beings serve alongside humans, and deep-space research has opened the door to something older than humanity...and far more sinister.

The game is close to release.

FILE 002 // CORE PILLARS

Three Pillars

Pillar 01

Corporate Dystopia

Eight major megacorps own the contracts, the medicine, the ships, and the future. The Earth Compact maintains the seblance of law. You are the difference maker in that bleak reality.
Pillar 02

Manufactured Humanity

Artificial Persons run the machines humans cannot survive. Biological Persons bleed, dream, remember — and obey. Many never learn what they are. But when they do, there is usually blood.
Pillar 03

Cosmic Contamination

Corporate research and profit motive systematically produces -- or uncovers -- bizarre Lovecraftian horrors and consequences Man was never designed to expereicen, let alone overcome. 
CMC // DEPLOYMENT BAY

Brief defiance, expensively purchased, against a bleak backdrop that doesn't change…unless you make it change.

Campaign Modes

One ruleset, six ways to die. Black Margin supports radically different tables — from marine deployments to noir investigations to lonely frontier survival.
Mode

Military Horror

Compact Marine Corps against the unknown. Standardized gear, expendable squads, things the briefing did not mention.
Mode

Noir Investigation

Auditors, Runners and ARAs working rain-slick colonies and corporate facilities where every answer costs more than the question.
Mode

Frontier Survival

Homesteaders, junkers and salvage crews living beyond regulated space, where help is never coming.
Mode

Corporate Espionage

Internal security, sabotage and the quiet wars between Tier 1 megacorps that the public is told were "resolved through negotiation."
Mode

Synthetic Identity

Play an AP or Bio uncertain of their own directives. Discover what you are. Decide what to do about it.
Mode

Cosmic Horror

Anomalous Knowledge, Drift, and the slow contamination of everyone who studies what the Tottenheim Field really is.

The Margin & the Tottenheim Field

Beyond regulated space lies The Margin — the boundary around the Tottenheim Field, where physics fails, ships disappear, and corporate research continues anyway.
Publicly, the Field is a beautiful astronomical curiosity. The operational reality — ship losses, anomalous physics, researcher psychological effects, and the Progenitor remains buried at Lothos — is hidden behind the public framing.
