London, or The Haunted City
This roleplaying sourcebook details an alternate-history London in 1879, where low-level magic, industrial expansion, and emerging electrical technology shape life in the British capital. It describes the city’s boroughs, neighborhoods, businesses, transport, communications, politics, royal family, criminal underworld, culture, history, and magical practices, with locations and adventure hooks for each area. The book also explores secret societies, research departments, and the workings of the British Empire. It concludes with a complete adventure, “Baby Boojum,” involving a kidnapping that goes wrong.
