Posted by Michael O'Brien on 10th Sep 2026
Now available on Virtual Tabletops! — Innsmouth and Arkham, the two superlative titles in our acclaimed 'Arkham Unveiled' series for Call of Cthulhu!
Call of Cthulhu Innsmouth on Roll20 VTT
Call of Cthulhu: Innsmouth is the definitive guide to the rotting seaport town—one of the most iconic settings for Call of Cthulhu. And now it is available on Roll20 VTT!
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. 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.
