Hello all, Tocharians were an ancient Indo-European people who formed one of the first wave of migrations out of the Proto Indo-European homeland in Ukraine and were dominant in parts of Tarim Basin and surroundings. What do you think they could have done early(after diverging from PIE) to have survived into today as an Eastern Indo-Europeans today with a sufficiently large nation on greener and habitable lands and good number of population. You can have them follow either Buddhism or Tocharian religion or even Christianity. Point to any alternate migrations and settlements. Have them East of Ukraine. Rest is your wish.
