Chapel of the Rotten Claw

From the publisher blurb:

A mile from the village of Breckdell is a solid oak door built into the side of a steep hill. Rumours claim that the door once led to a chapel of an evil cult that terrorised the area many years ago. Not much has been heard of this cult of the rotted claw and locals presumed they had left or be slain, and as the years passed memory of the cults activities were forgotten by most. In recent weeks hunters have claimed that they have seen the door in the hill open, and an eerie light emanating from within.
Fear that the cult may have returned the village wants to hire some hardy adventures to investigate and put an end to whatever evil lies within the Chapel of the Rotted Claw.
