I'm wondering what the world at large would look like at the point of Alexander's death ITTL, because Alexander basically changes the course of most of Eurasia, from basically leaving Greece to becoming a Persian province and leading the Tocharians west against the Warring States instead of south as IOTL, to turning Gojoseon into a far-flung Helleno-Tocharian kingdom.
So I really want to see what other effects Alexander's Catabasis could have had on the world.
