The Nest

From the introduction: The tiny Hamlet of Ratzburg needs your help. Several local children have gone missing, and all clues point to subterranean passages and chambers beneath the old mill on the outskirts of town. A large hole discovered in the cellar reeks of rodent filth, and distant squeaking sounds seem to confirm the existence of a nest somewhere beneath. User summary: For 1st - 4th level characters.
