Locate Mary and persuade her to give up a reflective surface for Viktori's project.
According to Cog's blueprint, what I need now is a way to reflect light. I remember a woman by the name of Mary who became well known around these parts for always carrying a looking glass. Perhaps you can track Mary down and see if she might lend us a reflective surface for this project? I believe she once resided in southern Duskwood. . .
