You and your few remaining creations are weary and tired after escaping your latest near-death incident. Someone in town had found out about your experiments and, sure enough, formed a lynch mob. You manged to escape relatively unscathed, but some of your notes were lost and you need somewhere to sleep for the night. You have decided to enter the underdark, knowing the villagers would never follow you there. You have just found the entrance to a side cavern. It appears to be a mine, but was likely abandoned long ago.
