As I said, it's a work in progress - I suppose it will be a WIP indefinitely, as I extend it and add detail. At least half my adventures are on the periphery of the underworld "Ur-Menig", so eventually there will be a version that shows where that lies, and some of the ways up and down.
There's something about this sort of map that tugs at my heart, it's like a gateway to hundreds of places, each one containing some detail of interest, a mystery, adventure, or a poignant ending.
I've always felt this way about maps, but I imagine that the beautiful cloth maps of the early Ultima series cemented this feeling. Each point of interest on those maps was an invitation to explore a richer world.
This map doesn't have that level of reality behind it, and it may never, but if you look at even one place on it and wonder what's there, we're sharing the same feeling.
