That's not a bad idea. I'll be checking by to see how you fare, especially to see how you manage to add something some of the more unique pieces of the world, like the city of Vivec, even if it's just a piece of the scenery. I was planning at one point to make a detailed map of Britania in the game, but I'll wait and see if they manage to add that overlay that would allow loading of images to use as outlines for the map editor.

Yea, the Telvanni have some strange buildings, good luck.

I made some mistakes in scale at first, so it is longer than the actual game and will be shortened as I move up the map. The lower parts are pretty well terraformed though. 

I also realized how to make a mountain looking area passable. If only I could grey it out it would be perfect.
