Right now, A!A is in the progress of rewriting part four for the fourth(!) time, not including the first three approaches before A!A threw everything in that out of the window and started anew. Mostly because this stupid chapter is placing the foundation for close to all future parts of the story.
Hopefully, by the grace and blessing of [insert deity here], the chapter should be finished in a week or so's time. It is not likely that it will be finished before the weekend, however. Check back after that.

Sorry about the delay.
