Well, actually day 2.5. I've written out my descriptions and started in on the ending. So far, I've fixed the scene where Karon knocks down the doors, smoothed out the Josef fight. This morning, I completely redid Renaud's speech explaining what the pillar was, and I think it's much better, much less info-dumpy. I also took out the blood magic thing, I can save that for another book or add it in a lesser capacity for this one later. I also had Renaud go into the pillar, which solves the whole "where is Renaud during all of this?" question AND is super creepy. This changes a lot of stuff down the road, but I think it'll all work out for the better. This climax has to flow properly, or there's no fun at all.
Next up: Battle of lava and sewage, then Nico. Don't forget to keep an eye on the ACTUAL text edits now that you're not writing new stuff.
