As long as Eunasia continent is inhabited with humans and Elves, I'm pretty much fine with that.

I do think that the center continent should have an Elven name. No matter if there is a "God" or not, we can all agree that Elves (and perhaps dwarves) were the first to arrive in Eizon. So the center continent would most certainly have the most divers population, but still named by the oldest race.
