Investigations au XIXe siècle

This roleplaying supplement presents the Victorian era at the end of the 19th century, a period of imperial rivalries, colonial expansion, scientific progress, and emerging global conflicts. Investigators confront the horrors of the Mythos alongside figures from Victorian imagination, including Dracula, Professor Moriarty, Martians, Jack the Ripper, ghosts, and other folkloric creatures. The book includes historical background, period photographs, and three original scenarios: an occult investigation introduced by Doctor Watson, a Lovecraftian horror involving a British family’s secrets, and a fantastic adventure centered on mysterious rifts in northern Cameroon.
