From publisher blurb:
The Eventide Valley has always been a place of mystery for those who dwell in the surrounding lands of the Great Empire. Isolated, backwards, and content to keep to itself, the valley has always been a source of rumor and legend. You have come to this valley to discover its secrets and find yourself in the peaceful shepherding village of Argylby, which has been the victim of raids by a force known only as the Outer Ones. But is there even more going on here than you suspect?
This module contains both a Lovecraftian fantasy adventure and a complete mini-setting (the Upper Eventide Valley) suitable for further adventures.
This module has been designed to complement the Swords of Cthulhu rules supplement. Swords of Cthulhu is not required to enjoy the module, but will most certainly enhance the experience.
