Publisher's blurb: As the party settles in to their new home in Trollskull Alley, the neighborhood welcomes another addition. A lady from a faraway land has acquired the old Priory of the Overgod, a long-abandoned structure at the eastern end of the alley. Shortly after Lady Boguescu and her small retinue move into the priory, strange occurrences begin haunting the alley. The east end of the alley sees an uptick in vermin, and a strange fog seems to fill the alley, regardless of the season. Shadows seem longer. Soon Fala Lefaliir begins complaining that their supplies are spoiling. Will the owners of Trollskull Manor be able to discover the nature of these dark disturbances and put a stop to it? Or will the people of the alley fall prey to the Lady of Trollskull Priory?
