Some progress. I decided to go start putting in points of interest.

So far I've added the Sky Hall, four infandibulum vents, and the Well of Abundance. Oh, and I've decided that waterfall leads to the city reservoir. I cleared out some houses along the north east wall -- there's going to be a university campus there. On my todo list are the aforementioned university, the Observatory Arcane, a cathedral or shrine of some sort, an amphitheater and possibly some barracks of some sort. I'd really love to put in some electrothaumaturgical batteries, but those are zappy things on the bottom of the city where you can't really see them while it's landed.

For the moment the points of interest are bright and shiny and new looking. I'll go back and dirty them up later.
