That stuff is awesome. I'm half convinced that Tartaria actually existed and the expansion of Rus east was partially a cover up.
I find it hard to believe that throughout all that area above the steppe was just filled with native American /Eskimo type boongs that never got to an iron age.
The tocharians (language group, not exactly an ethnicity) were out that way and built pyramid mound burials and chariots and shit, but their neighbours never adopted any of the technology they brought.
