In Ireland, an archaeological team unearths an ancient horror, trapped within three stone vessels. The foul entity sets its followers on a journey to free it from its prison, crossing the Atlantic to New England and the backwoods of rural Massachusetts.

Across three connected scenarios, the Investigators must thwart the evil plot of the cultists!

Call of Cthulhu: The Order of the Stone contains everything a Keeper needs to run the campaign, including a full suite of maps, resources, and handouts. Also included are a collection of six pre-generated investigators.
