From publisher blurb: Your passage to Cathoway has gone slower than you hoped and a looming thunderstorm concerns you greatly. The Iron Hills give an eerie sense of doom as streaks of lightning begin to brew. Fortunately, a strange mansion sits on a hill in the vale and may perhaps offer safe harbor to you! This adventure setting was designed for 5th Edition rules for the Filbar Campaign for six, initial level adventurers and DM.
