I was asked to clarify my ideas for the cultures of Mirhandia. Here is my take on it. I will also add this to the first page.

Just a brief skim through of how the cultures are in Mirhandia. 

The hub of kingdoms around the Jadelyn Empire, as well as those nations around Suratar can be considered a late medieval time Europe. The Jadelyn Empire is considered as one of the more powerful nation of Mirhandia. The natives there are similar to Europeans. 

Below Tysus, as you go down to to the Tetrarchy of Klanat, think the Middle East/Arabian sort of vibe, when they were at their peak. Golden domes, skilled archer riders, that sort of stuff. The natives there, you guessed it, are a darker skin color just like the natives of the Middle East.

To the west of the south-west of the Tetrarchy, arround Dissor, we have a kingdom coalition of kingdoms and countries which are mostly covered in forests. The people here are of a more lithe, taller build, with tanned skin and slanted eyes. Some of the greatest archers in Mirhandia come from those parts. Also, a non-human rice similar to elves dwell in those parts, although very secluded. 

To the west of that, Xenth and Athet. Athet, and half of Xenth, are covered by expansive jungles. Think of the African jungles. The people here are dark ebony skinned. The second half of Xenth is a desert. 

North of Xenth, that whole continent with Nibas, Niseoma, etc... has similar physical attributes and culture as of Asia. To be precise, Japan/China.
