From the first page of the adventure:
The Shou town of Kudoku is in despair. Its magistrate once embodied a set of principles that guided the village, but he was murdered by assassins known as the Five Deadly Shadows. The principles have been corrupted and now protect the assassins. Can you recover the principles and best prevent the town’s destruction?
