Your not so far from the mark, Peter. I've mostly looked at Scythians and Parthians so far. I definitely don't want the Game-of-thrones-horsemen or Djenghis Khan. On a side note, I've looked at cucutenian-tripyllian stone age clay figurines for the half elven druids that honor the god ”Drejaren” – ”Clay” (Gods mostly have short names like ”Rust”, ”Heme”, ”Clay”, ”Flow” etc – English names to TBD) from the same area.
Now this is very cool. Wasnt familiar with Cucutenian-Tripyllian culture but those figurines have a lot of personality!
Completely agree on staying away from the dothraky/horde stereotype (now, a proper horde is different. The mongol armies were very organised and 'Ordu' is stil the Turkish word for army.) It would be very cool to see steppe peoples as a rich, chivalric - channeling Rustam more than Genghiz Khan
