At her question, the man looked far more concerned. "I see... one of two dangerous possibilities," he said. "The first is a powerful, undead creature, that draws lesser ones to it. If that is the situation, then... we likely do not stand much of a chance. On the other hand, such creatures are rare, and leave swathes of destruction in their wake. If it were such a thing, it almost certainly wouldn't have stayed this well-hidden. More likely is a mortal, a magic user in the arts of necromancy. A crueler version of magic than what your creator uses, creating to serve him, like you do with yours, but using the bodies and spirits of people, instead of aetherial energies and willing spirits," he explained. "In that case... the difficult part will be finding the master. Once we slay him, the rest will be much simpler to dispatch."
