The Order of the Stone is a three-part campaign for Call of Cthulhu, the original game of horror, mystery, and investigation!

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. Can the investigators prevent the liberation of the Ruler of Chaos? Will they discover the secrets of the Order of the Stone?
