This supplement features Mandy’s collaborations with nine other famous investigators, such as Silas Marsh, Trish Scarbrough, and “Ashcan” Pete, as they research over 50 eldritch horrors; both infamous and hitherto unknown. In the collection of notes and documents, you’ll also find each of these investigators’ own observations on these creatures’ habits, dangers, and weaknesses, as well as nine mini mysteries to help you incorporate these abominations directly into your game!

*Note: The Thompson Files is a bestiary for Arkham Horror – The Roleplaying Game and requires the Core Rulebook (243316) to play.
