Update: I've incorporated clickables, and revamped the geometry of the Prin Pahts/nexus. I also incorporated an untextured version of Besharen's pedestal.
Follow the directions in the first post to see the latest. Here's a preview image:
Picture of PrinpahtsThe scripts are flexible enough to handle any number of linking books/points in the city and in Prin Pahts/nexus. So, I should be able to reuse it for the final Ahra Pahts version.
The geometry of the Prin Pahts/nexus now contains a higher ledge from which you can see the entire map. Ideally, the walls would be textured, and there would be tunnels cut through the corners. Even more ideally, there would be three bridge spans reaching out toward the center, on which would be the linking pedestal to the upper level of the Hub in the city. Alas, I am not a modeler.
I did add lighting though - red/blue/green for the appropriate district.
