The Restless Knight

From publisher blurb: The Fallstones have a problem. The ghost of a man clad in armor haunts the inn they recently purchased. Its presence seems to have cursed the place, bringing all sorts of unwanted guests to the inn’s doors… The Restless Knight is part of a series of mini-dungeons designed to drop into existing adventures or campaigns. Use them as side quests or a way of getting in a quick adventure when you’re short on time.
