There really are a lot of tempting areas. I think a district is missing a number in between 33 and 37 and also just below that. I also assume we want to fill up the city in the walls first and then move to the outlying areas or is it all just in the air?

In any case my order of preference is: 7, 14, 12, the un-named one in between 33 and 37, 27, 32, 24... actually I could keep on going since it's all pretty ineresting, so if this list interferes with anyones first choice I'd be happy to move over.
