When you are aware of it you can see relics and remnants of the old Tartarian civilization almost everywhere. They were in numerous ways more advanced than we are.

In America various Native people from the north moved down after the climate change but were all forcibly removed many years later by the new American military. This cleared the way for the replacements. A considerable number of whom were from the breeding programs of the new world leaders.
