From the front of the book: The Disquiet Spirits is an adventure designed for five 5th- level player characters (PCs), and is part of the D&D Delve Night kit. Please review the instructions for use of the D&D Delve Night kit before using this adventure. The adventure uses tiles from the DT4: Ruins of the Wild and DU3 : Caves of Carnage. The ancient, protective spirits in a stretch of primeval wilderness have become restless. The people living there are being attacked, both by creatures no longer afraid of the spirits' wrath and -- the people say -- the unleashed spirits themselves.
