Overall im in love with the idea and can see myself running this with all of its twists, but some polishing and elaboration is needed. I think with the horror specifically having a system or guide, however barebones, to guide the warden on making the horror would be greatly appreciated. For a module that relies on the threat so heavily, I find it odd the module omits any stats or base abilities for the monster. I think adding that, even in supplemental form as an example would be greatly appreciated. Good work, my players would hate this (in the good way)
