While in building 199, they do make enough progress that a little bit of what passes for daylight here sneaks in through the ceiling. It's followed, immediately, by eyes glistening at the top of the vast pile. Eight, sixteen, twenty four, thirty two... Four large spiders make their way deftly down the pile toward the gathered group. They're not made of metal, no, these are fleshy and the size of a man. They move quickly--it's hard to tell that their eight legs are not a spider's appendages but human arms and legs haphazardly attached to a spider's body.
