ALL HALLOWS TIDE

THE SHADOW OVER GREYPORT On October 24th, one week before Halloween, a bitter sea-fog creeps over the town of Greyport, and something ancient stirs in the abyssal trench offshore. You are a Keeper of the Threshold, one of the few who know what the fog brings. You have eight days. ALL HALLOWS TIDE is a complete procedural solo horror RPG on two pages, designed for the Last TTRPG Jam 2026 and inspired by the GATEWAY RPG Core Rules. Over an 8-day countdown to Halloween night, you will search a drowning town, recover the four Sacred Incantation Seals in order, and reach the Cliffside Lighthouse on October 31st to perform the 3-Phase Banishing Ritual, all before your Stress Track fills and your mind gives out.
