From publisher blurb:
Buried 'neath a forgotten landslide, deep under the foothills, is a ruined cloister with a secret.
Long ago, nestled into the mountain there, it is said that a true saint lived and died. The pious woman never spoke a single untruth from the moment she drew breath, and the gods blessed her to continue speaking truth afterward.
Old folks whisper that the Healdess Saint is still enthroned down there in her lightless cathedral. They say that if you bring her a skull then it can be made to answer questions, truthfully, from beyond the grave.
The Buried Convent of the Headless Saint is intended to be an early adventure for a party of 1st level characters, possibly even an introductory adventure. There are very few unavoidable encounters within, there are some hidden secrets that reward attentive players, and the hazards should present interesting logistical problems rather than 'gotcha' traps. Most groups take around 1-2 sessions to complete the delve.
