IMO the lower left quadrant should be the Celtic or Germanic societies of the time (if we're sticking to Eurasia). They had quite free and egalitarian societies compared to the contemporary empires.
I was thinking that it wouldn't really be an empire, since it was more numerous communities that had a lot of differences and fight between them, but in the end it makes them even better for the lower left part
