From the publisher:
The crypts of Crowsmeet, ancient by most standards, have long held the remains of great heroes. Recently, a duo of graverobbers attempted to pilfer the remains of a cavalry soldier and unknowingly released his vengeful spirit onto the town as a whole. One perished within, while the other fled to the local inn, his ill-gotten gains hidden in his pack. Now, every night, the headless rider appears in the local graveyard and begins his ride through the town proper seeking his missing helm. Any who come across him find themselves at the sharp end of his blade. Thus, when the sun sets, the town shelters within the old church, waiting the rider out until the sun drives him back to his resting place. Unless someone can return the stolen helm or slay the specter, his reign of terror will continue unabated.
