An Observation Upon Revising Chapter 16

I'm finding that the more worldbuilding I packed into my chapters, the better the prose tends to be upon revision. Chapters 14 & 16 were tough to write because they were so alien, so I assumed they'd be harder to revise. But it's the other way around. The harder the chapter was to draft, the easier it is to edit. Maybe I was paying better attention to the hard stuff, or something.
