I know I say this about every part, but the next one is tricky.
The reason this one is tricky is that it begins the second arc of the story (out of three arcs). The second arc is the proverbial "second act wasteland" in which a lot is set up, but not much is knocked down. I'm looking for that magic something to keep things interesting, and while I've got enough to go on, I'm not quite satisfied. So I'm still thinking about it before stretching my fingers.
As usual, though, it will probably be done within a week.
