I recently came across my old copy of this book. I would always have it out and be reading lore about whatever zone I was in. Each zone had neat little maps drawn out for them too. It has zones up to PoP, I think.
I also happened to have recently found a magic wand scanner in the dumpster(In it's unopened shipping box. Weird? I know.)
Anyways, I took a couple of scans for y'all. If anyone wants one in particular, let me know.
