Mystery & Horror in the Victorian Age
Dark Shadows in the 1890s
Unleash the horrors of the Victorian night, reveal sinister secrets, forbidden lore, and mysteries of the late 19th century at your gaming table.
What's Inside
Cthulhu by Gaslight takes the Call of Cthulhu roleplaying game to the fog-shrouded streets of Great Britain and beyond. This book is designed for Keepers—those who will be running the game.
A World by Gaslight
Extensive advice for bringing the 1890s setting to life, including the Gazetteer of Fear—over 100 locations across Britain and beyond! The book also includes detailed information on villainous organizations and occult societies such as the Secrets of the Hermetic Order of the Golden Dawn.
Gaslight Mechanics
The Cthulhu by Gaslight: Keeper’s Guide includes rules for Monsters and Mythos elements unique to 1890s Britain. Inside, you’ll also find new occult-based skills, tomes, spells, and rules for combat upon the astral plane!
A Complete Experience
Cthulhu by Gaslight is a stand-alone version of Call of Cthulhu. Only the core Cthulhu by Gaslight: Investigator’s Guide and Cthulhu by Gaslight: Keeper’s Guide are required to play!
Scenarios
In addition to many scenario seeds to help spark all-new Cthulhu by Gaslight stories of your own design, the book includes two introductory scenarios, both designed for players new to the setting.
The Forby Masterwork
During the summer of 1890, the investigators are drawn into a mystery surrounding a cursed family, and must seek out a lost gem and uncover the truth behind multiple haunted sites.
Oranges & Lemons
In the heart of London’s Victorian slums, a gruesome death sees the investigators potentially infected with disease. As they explore events surrounding the death, they will uncover something lurking beneath London.

Super awesome with just one small hiccup!
As was with the Investigators Guide, the Keeper's Guide does not disappoint. It's well written, chocked full of great information, story hooks, and two very cool, and interesting scenarios. My only slight, infinitesimally small complaint is that whoever set up the bookmarks for the PDF somehow missed Chapter 6 entirely. Like I said, it's a small complaint, but it didn't stop me from giving the book 5 stars. Thank you!
