Thanks for taking the time to play and comment with your suggestions! I really appreciate it. Since the adventure is a zine, the details are maybe less than adventures you're used to. As a DM you have the creative power to make up those details yourself based on how your party is doing :) And if you want more mill equipment, feel free to add it in. In my head, most of the equipment was transferred to the new mill when the town built it.
Happy adventuring!
