There the cultists plot to conduct a ritual to resurrect the notorious villain, using their collected relics to transform an innocent into a new undead body for the imprisoned archmage. Can the heroes withstand the ageless evil of Gallowspire to finally defeat the Whispering Way? Or will the Whispering Tyrant, one of the greatest fiends ever known, be unleashed upon the world once more?
