Please correct me if anything looks off, but this is what I believe to be correct, after a fair amount of measuring: 1 tile is 4mx4m 1m is 10 dirt (If a cave "cube" of rock is the same height as width and depth, then it should be correct) A Xan map grid is 400 tiles, which = 1600m The map is actually 20x20 map grids. When you sail past 20, you cross, even though the map drawing looks slightly bigger. So, 20 x 1600 = 32km across the map. If all of that makes sense, then I believe there are 64 million map tiles on Xanadu. If every tile could be deeded, it would cost 6400 Gold (1c per tile to deed) and 1280 Gold in upkeep/month. Also, I believe flat top mountains to be somewhere around 10k-12k dirt high. *ALL feedback is welcome. If I am wrong or just did dumb math, I'd love to get it corrected. Thank you!
