Only 701 words for the first hour. I almost immediately found something I needed to look up and that slowed me down quite a bit. This first intro chapter is very short. So far, it's going well. I need a little more detail in it, but the feel is there.
I'm going to be slow in hour two as well. In fact, I probably won't get more than a couple thousand done tonight. But so far, it's going much better than the earlier version.
