Grim & Perilous Solo Rules

A solo-play rules supplement for a grim and perilous roleplaying game, removing the need for a Games Master. Tables and dice rolls resolve questions about the world, scene objectives, NPC reactions, and other decisions normally handled by a GM, using the game’s existing mechanics. The supplement also includes record sheets for tracking solo adventures and an example playthrough covering the opening scenes of a new character’s story.
