From Chaosium:
IN THE 1890s, Cthulhu and his minions share the globe with the mighty British Empire. But they owe allegiance to an empire of their own — a dark and cruel design on ownership of the world and on the dreams of humanity. Even among the green fields of rural England, only thoughtful and energetic intervention keeps the shadows at bay. CTHULHU BY GASLIGHT offers a thoroughly developed Victorian England setting for use with Call of Cthulhu. Character creation has been enhanced with new wrinkles. There are articles on the Victorian world, crime, politics, personalities, and so forth. There are extensive sections on the Cthulhu Mythos in Britain — creatures, cults, and books — and a précis of Ramsey Campbell’s Severn River Valley. Also included are tips on running various types of Gaslight-era campaigns, a gazetteer of intriguing British myths and legends, a selection of friends and foes from Victorian fiction, and a lengthy bibliography/filmography of suggested reading and viewing. Rounding out this edition are a pair of Victorian-era scenarios — one an urban adventure set in London, the other set in rural Dartmoor. Includes a two-color, fold-out map of the City of London.
Kudos to Chaosium for harkening back to Lovecraft’s true love. No I don’t mean Cthulhu mythos, I mean the seat of Anglo centric power, Empire England! Lovecraft himself probably would have preferred to play the 1890’s version of Call of Cthulhu.
