Just for posterity, here is a page of scribbling I did trying to block out what I thought would be the final 10,000 words or so of Airworld. What ended up happening is that I raised more questions than I answered, and all the answers started branching off into all these other fairly massive sub-plots. You may also notice there is a whole new, vitally important character in there that was introduced very late in the story. (Just in case I everĀ do finish the story, I blurred out some spoilers.)
(I’m not really sure if the page-of-scribbling technique actually works for me as a writer.)
