In 227 CE Hadrian’s Wall in Britannia, and the brave auxiliary soldiers who man it, provide the physical security for the northern frontier of the mighty Roman Empire. However, only some enlightened few understand the graver supernatural threats lurking among the dark forests and trackless marshes of the border region. Those few are yourselves, the Brotherhood, initiates into the Mysteries of Mithras who serve among the auxiliaries at the Wall. Some time ago a Roman trading ship was lost along the coast north of the Wall. Sadly, this is not unknown in the rough seas around Britannia. However, items from its cargo have recently begun turning up bearing strange new marks. The locals claim these are cursed and related to a spate of disappearances. After your previous success with delicate esoteric matters, the Governor has instructed your Prefect to assign the Brotherhood to investigate.
