I wonder at what point in her book's development was this written? I know there are aspects that changed after she wrote this page. I'm curious how much she had before starting on manuscript pages, or if this was created further along to solidify the pace in her mind.
I'd have trouble separating all the chapters with this much detail, very early in the work. But then she already had a concrete world and plot with 4 books behind her to draw from, so I'm sure that made it easier.
