My character's names are from very random inspirations.
Main character is Zerwan, it's from the god Zurvan.
Hlaluu is from TES3:Morrowind
Leelah (=Leila) is an Arabic name chosen to both alliterate and assonate with Hlaluu.
Tsegerl is invented, but I was thinking of Tsetseg, a Mongolian girl's name.
The cities/regions have even more random names, supposed to illustrate both geographical and temporal (successive) cultural influences.
Ah yes, @QueenofBabyLoon, I don't know if I should thank you or not for your naming 

I have a strong but fluctuant obsession for the Sumerian and Akkadian languages. But because Sumerian is a language isolate and completely useless in everyday life, I really, really don't want to give in. I'm struggling since years to avoid spending any time on that. Akkadian is not off limits per se (I allow myself study time for anything IE or Semitic because some languages have some practical interest in my life, although it's pretty much an excuse) but well, you know, Sumerian influence, bla bla, that would really be an big, lame, excuse. I don't think any knowledge of Akkadian would improve my Arabic haha
