Cursed Chess Set is an expansion by Zarista Games. It's intended for low level characters.

While you were adventuring in the country of Staunton, someone destroyed the King's two landmark Watch Towers. Witnesses swear it was you. The King has put a large bounty on your head so you face grave danger. You remember seeing two rat-like figures scuttle away when the towers vanished. Can you find them, learn what happened and emerge unscathed?
