OTL the Indo-Greek kingdom ended in the 10 A.D In this alternate Timeline that doesnt happen and the Indo-Greek Kingdom survives.
It would have conquered northern india.
Because the Indo-Greek kingdom survived the culture of northern india would be a mix of greek and indian culture and since the arabs still exist and conquer the area of OTL pakistan there would be dialects of greek written in the arabic and sanskrit script and zoroastrians would become a large religious minority in the Indo-Greek Kingdom.
A lot of the land would have been hellenized and would have a lot of greek settlements which would expand greek culture even further.
I also have a map for this scenario
