[@Gig][@Cyclone]Yeah, the desert area is lot less than 2/3rd of your area.Albeit it isn't completely insignificant, either.
It takes up the centermost part of your territory with a size almost equal to Gig's Setra.
On the other hand I think you can take advantage of this and your diverse lands.
Also the geographical map actually has a scale for us to use so I can more accurately estimate how large my population should be.
Keep in mind though that circa 20% of my population is elvish whithin the core worlds which would obviously shift the demographics.
