What begins as a simple but lucrative express cargo charter quickly turns into a mystery. A plague of bad luck and misfortune seems to hit the adventurers at every port of call as they carry their cargo across two subsectors to its destination in the Grand Duchy of Stoner. Who is hounding the characters and why? And what will they do if the adventures refuse to cooperate? All aboard for the Stoner Express!
