Sector-Sigma

Sector-Sigma is a dedicated post-apocalyptic psychedelic cosmic & body horror setting / scenario crafted for the Fate TTRPG system. It plunges players into a world irrevocably altered by the Double-i's Emergence, a cataclysmic event that birthed an ineffable zone of impossible phenomena, alien life, and profound psychological and physiological strain: The Sector.

Utilizing Fate's narrative flexibility and robust aspect-driven mechanics, Sector-Sigma provides a rich tapestry for stories of survival, exploration, and moral ambiguity. The setting's core truths, faction dynamics, environmental hazards, and personal transformations (mutations) are directly expressed through Fate Aspects and Stunts, allowing for seamless integration of lore and rules.

Players will navigate a shattered world where conventional logic fails, interact with desperate factions like the Global Coalition, Gilded Cage Cartel, Harmonizers, and Watchers, and grapple with the very nature of humanity in the face of the truly alien, all while actively managing Fate Points to shape their destiny amidst the chaos.
