Can someone explain Shetiona names to me?

[Gwenkatsu]

I wanna make a character that's from Yyasulani, ,but without knowing what the language is based on, or even have some kind of clue of their naming conventions, it's so hard!

If I were you, I'd take the above list of known names, feed it to ChatGPT with a prompt like "Create a name in a fantasy game that matches the following already known names:", and see where I get from there.
