What the Seablight® Antilles Setting Guide Contains
Seablight® Antilles is set in the BlightHope Epoch, a post-apocalyptic future designed by CreatePlay for the Basic Roleplaying: Universal Game Engine (BRP) published by Chaosium Inc.
The setting guide focuses on the islands of the Antilles Archipelago in 2467 CE, which is bordered by the former Caribbean Sea, Gulf of Mexico, and the Atlantic Ocean. Earth has been suffocated and ravaged by Seablight, a parasitic space virus. Players and GMs will enter a world of post-apocalyptic Pyrate warbands, psychic mutants, and island-based micronations.
The following outlines each chapter within the Seablight® Antilles TRPG Setting Guide. This content is also available as pages and posts on this website (see Content Index for quick navigation).
CHAPTER ONE: CHARACTER CREATION
This section guides players through the character creation process, as outlined in the BRP core rule book (available from Chaosium Inc). The setting guide also introduces modified rules tailored for playing in the Blightdark Epoch.
CHAPTER TWO: CULTURES
This section provides a summary of the four distinct major cultures that comprise the Antilles Archipelago of the Blightdark Epoch: the Hopesail Confederacy, Masqued Guildas, Pyrate Republic, and Blighted Tribes.
CHAPTER THREE: HEROIC PROFESSIONS

CHAPTER SIX: VESSELS
The calamitous upheaval caused by the Seablight Deluge and Century of Deconstruction has resulted in the development of exotic modes of sea, air, and land transportation. The vessels section provides details on the types of craft that players can encounter, purchase, steal and pilot. It also introduces rules for power sources, maintenance, and crew responsibilities.
CHAPTER SEVEN: EQUIPMENT
Exploring and surviving the Blightdark Epoch requires having the right equipment. Currency, gear, goods, weapons, and gadgets unique to Seablight Antilles are detailed in this section.
CHAPTER EIGHT: BESTIARY
This chapter features a bestiary of unique hybrid creatures, ciber abominations, blighted xeno-bioforms, and dangerous groups that inhabit the Antilles Archipelago.
CHAPTER NINE: SCENARIOS
This setting guide provides players and Game Moderators (GMs) scenarios for situations, missions, contracts, dilemmas, and other activities they can undertake in the Antilles Archipelago.

Hunger in Haiti
At the time of Seablight® AntillesTTRPG Setting Guide publication in June 2025, a staggering 44 percent of Haiti’s total population is acutely food insecure. Families are being forced to abandon their homes and farms to flee the escalated violence.
Families, especially women, children, and the elderly, who are facing emergency levels of food insecurity need immediate aid to avoid slipping into a hunger catastrophe.
Haiti needs more than boots on the ground to build a peaceful and prosperous future for its people; the country will never be at peace when nearly half its population is starving.
