Went digging through the old COT2 today, looking for more good things to salvage for the new version. I didn't find much. Really, I barely found anything.
What I have for COT2 is in a bit of a pile. It's about 200,000 words long, with no chapter structure or any sort of clear narrative. There's a couple of story arcs going on, which fade in and out as the story progresses (told strictly chronologically) over the course of several months. It generally results in a convoluted mess that has no clear purpose or direction.
I'm going to start laying down the blueprints for at least a half-dozen of the stories which will form the starting point for COT2, but now it seems I'll be doing it without the aid of the existing text.
