Lets review several variants for maps:
The first variant is the most simple:
Here are all merged into a single border Saka with the massagetae.
Dahae separately (although consisted of the same Saka and massagetae).
the second variant:
оr
Here the massagetae were separated border
and the third variant (difficult, but closer to the historical):
Wusun in the middle of the 2 century BC, from the East and seeking to seize territory (modern name Zhetysu)
*We can make a small area of the parni in southern borders of Dahae. Or whether the Dahae in the time attack will be called the Parni province (for example, 247 BC)
In my opinion: this variant is optimized for games
*Oops, mistake. "sarmarian" read as "sarmaTians"
