Lerayis is a continent and the Godwastes are in the north, it makes up the majority of the northern areas of the continent. The Hattavori desert lays in the south, below Worsenth and Vallake. 

The description of the Godwastes is somewhat misleading but the area is barren tundra. It’s incredibly cold, more so as you go further north but it does not snow there nor does it rain leading to the cracked ground and rather warm sounding conditions. 

Please take note that most places within this world defy physics and normal weather conditions, as its flat. So, while Lerayis is comparable to say, Europe, it’s best not to compare places within this universe to real world counterparts. Technically we shouldn’t even have seasons but, Gods are weird, whatcha gonna do?

People living in the Godwastes are a mix and match of many cultures, some even having their great grandparents or beyond not even hailing from the continent. The Godwastes also expand such a large area that to speak of the native people already covers a large range. Due to the Gods’ deaths and the persecution of mages, many magical folk north of the desert moved into the Godwastes as such every ethnicity is represented. 

I can give a list of each regions general ethnicity, if anyone would like.

Edit: I should probably also tell all of you, Untuillia will not feature on the map. It's an island nation off the east of Lerayis, about a month away by boat. There is a small minority of them within Lerayis though most know little to nothing of their culture. The nation of Untuillia has had little to no contact with it's neighbor since the Gods' death, being a very religious people themselves and seeing what the Lerayissians do as unforgivable.
