The definitive guide to the rotting seaport town of Innsmouth—one of the most iconic settings for Call of Cthulhu.
Once a thriving seaport on the Massachusetts coast during the 19th century, a dark shadow has fallen over Innsmouth—Some say old Captain Obed Marsh made a pact with the Devil, while others tell stranger and more wicked tales.
What's Inside?
In the early 1920s, the town’s former glories are long forgotten, and wise folk keep away. Secrets have a currency in Innsmouth, and the unwary pay a high price for asking the wrong questions.
A Sandbox Campaign Setting
An essential resource for Innsmouth-based scenarios as well as campaigns within the wider Arkham and Miskatonic Valley region. Description, insights, and plot seeds from over 100 Innsmouth locations in and around the town.
