What if there was a stronger Hellenistic empire in Asia? The regions where Alexander the Great had the Greeks settled and established the Indo-Greek Empire was in the midst of Nomadic peoples.
What if the Graeco-Bactrian/Indo-Greek Empire incorporated Sogdia, Tocharia, The Dahae region upto the Aral Sea in the North and upto the Northern Indus valley and Punjab in the South?

How would this butterfly other events of that era and the coming eras?
