Then, given the average number for a given town, city or country, you can
assign a rural:urban ratio, which will proably be between 4:1 and 10:1,
depending on how consistantly good (or bad) the land is.
Thorin has some tremendously fertile land in Greenlen, and very nice land
in both Gar and Rhyn, but otherwise the land is too rough to do much with it.
This means that the average number for Greenlen might be 2, while Gar and
Rhyn are both 3. The values for the other areas might be closer to 7.
This probably sets the overall "land quality" number to about 4-5. So maybe
there will be 6 farmers for each city dweller (a random value--no game
mechanic exists yet to map these values.) Which means that Thorin's total
population is probably around 2.75 million people, given the following:
