From publisher blurb:

Type: Low-level (1-3) campaign-starter with a base of operations
In response to our readers, this is the Folio Edition of our first release, M1: Jewel of the Lunar Rift. This version focuses on the adventure and is more setting-generic with most of the campaign world information, and the campaign journals, stripped away. This version is also presented in 18 pages of 8.5" x 11" two-column format with easier-to-read fonts.
Things are not right at Du Sharid Manor. Months ago, a deranged parish priest and his most devout followers formed a heretical cult. These self-proclaimed “Seekers of the White Heart” chose the desolate Wild Hills to practice their secret rites; but the strange goings on at the Wild Hills did not escape the prying eyes of the more pious villagers who set out to confront the cultists. Once there, the villagers witnessed something terrifying and unexpected. Since the events of that night, the cultists have vanished, but the remaining serfs of Du Sharid now live in constant paranoia. Your party has been hired by the local bishop to to learn the truth about what happened at Du Sharid Manor. For use with Swords & Wizardry (or the like) and designed for the experienced Referee, Jewel of the Lunar Rift is a first-level campaign-starter taken from my personal notes and an introduction to my setting, Messoria.
