A terrible thunderstorm batters a seaside port, yet thunder and lightning are nothing compared to what is about to be unleashed by the diabolic crew of the Rabid Dawn. Casters with access to control water, control weather, or control winds will prove especially valuable, as will characters with strong Swim skills. The adventure is best suited to a predominantly good or neutral aligned party of PC's. Strike on the Rabid Dawn takes place in the port city of Hardby (Dungeon #109). As most of the action takes place within a lighthouse and on a ship at sea, however, any suitable port from your campaign makes an appropriate substitution for Hardby. Pgs. 12-32
