The rounder faces of Slavics relative to Germanics, who have more elongated faces, is likely due to Asian/Mongolian admixture. The Steppe Nomads like the Huns (creators of Hungary) and the Mongols, but also others in between them who made smaller incursions into Europe, have been bursting into Eastern Europe and occasionally settling in Eastern Europe and generally just intermixing with the peoples of Eastern Europe for around two millennia.
The Huns arrived in Europe, the promptly began attacking the borders of the Roman Empire and, soon after under Atilla, nearly overran the entire empire and conquered it (being stopped at a few key battles by a remarkable general who was swiftly executed after stopping the Hunnic invasion and threat because his power and prestige and ability threatened the dumb emperor of the time), are thought to have begun their westward migration, after departing a region of Central Asia adjacent to China, in the first couple of centuries BC.
This means that the Hunnic invasion of Europe that almost toppled Rome in the 400s was already set in motion around 500 years, or roughly half a millennium earlier, when a Hunnic group from Central Asia near Qin or early Han China began migrating west in what would become a centuries long processes of continual westward movements culminating in this group's arrival in Europe and confrontation with the Roman Empire.
So a group of horse nomads, sort of like the Dothraki in Game of Thrones (the Dothraki were based on the horse nomad peoples of the Central Asia Steppe, of course, such as the Huns and Mongols), and as this group continued ever westward in a process that consisted of stopping for a while in one place, settling down a bit, then up and moving west yet again, it encountered, of course, one group of new people after another in all those lands that this group of Huns kept moving into during its migration.
Since these Huns made it all the way to the European peninsula that forms the very
