Formed entirely of shadowstuff, Ranunculus passes through matter and living things. While objects are unaffected by its passing, living creatures, when struck, are stunned and descend instantly into madness, effectively removing them from any battle. Upon spoken command, Ranunculus will instantly return to its owner’s hand.
Near a major city, a mirror image of the place has appeared. This strange double is infested with hostile insectoid humanoids that appear to match the city folk in numbers and armaments. The humans’ diviners have determined that the secret of the city’s appearance can be found within the double’s college of magic, so heroes are needed to explore within this mirror city and discover what has drawn it from its distant realm. There isn’t much time to spare, as the bug folk find their mammalian counterparts unnatural and blasphemous, and plan to destroy them.
