I realized I had forgotten to mention, but I have finished a draft of the entirety of Volume 3 as outlined in my structure above, so I am ready to post whenever. I have not done so because we are already in the midst of so many chapters, I did not want to derail the discussion more than I already have in the past.
Doing these edits has given me some new thoughts on various chapters Fin and I have reached a consensus on. I will address those as Aiwendil and others begin to discuss the respective chapters.
