Cthulhu by Gaslight: Keepers' Guide

A guide for gamemasters running horror roleplaying set in late-Victorian Britain. It presents advice on evoking the foggy streets and period atmosphere, details villainous secret societies and occult groups, and outlines Mythos creatures adapted to a Gaslight-era setting. New rules cover occult skills, spells, tomes, and astral combat, plus scenario seeds and two introductory adventures to kick off campaigns. The book assumes a separate core rulebook for player characters and encourages integration with other supplements for broader or pulp-style play.
