You really nailed the theme! Also, I like the monofiber as a macguffin, very nice.
Feedback: I think a dash of colour might help punch this up a bit. Also, because you don't get the monofiber until the fourth story encounter, some of the locations (like 42, 52) might not make sense if you hit them too early. Maybe a depth-crawl structure could help you add more pacing? Something to consider, if you want to revisit this.
