From the publisher blurb: This is a Medieval Mythos Mystery adventure-setting for 3-5 players and a GM "Your Baron, the honoured Philip De Guiarme, has set you on a mission. As a result of being on the correct side of a recent revolt against the king, he has gained land and prestige. To this end he wishes to assay all the wealth and holdings of his newly acquired, but rather sparsely populated, barony. The King himself has been considering such an endeavour for all the land due to the recent upheaval, and Philip, being the smart man his is, wishes to get ahead of the game in case he finds something of great value, which he may need to declare, or not. You, and your worthy companions in arms, are being sent to the Southern Fenlands to carry out this task and to especially investigate a coastal village called Honningsby which seems to exist on a map, but no one has had word from them in many months”. The adventure is systemless and assumes the use of a relevant roleplaying system dealing with mystery and eldritch horror.
