Against the Mythos in the Down Darker Trails setting.

Shadows Over Stillwater is a collection of scenarios and locales for —the Wild West setting for . Contained within are further insights and challenges for those seeking bold adventure in the American Old West.

Featured is a three-part campaign—The Shadow Over Stillwater—set in the mountains of the New Mexico Territory. A hunt for a fugitive murderer leads the investigators into a mystery involving odd townsfolk, strange lights in the sky, walking corpses, and the machinations of a once-powerful and ancient race seeking to reclaim their lost glory.

The campaign is suitable for groups of any size, as the Keeper can easily scale the opposition to reflect the number of investigators. An apparently simple task, bringing a wanted man to justice, brings the investigators to a town suffering an epidemic of bizarre events, from crazed residents to the dead rising from their graves.
