Word of God is that Zerans aren't in Korvara because they're exclusively from Alstalsia which doesn't exist here. Mechanations also got the ban for being from the Mechana Forest (which Papillions are also technically from yet aren't banned), and Lich/Dullahan/Vampire all got banned for being immortal but we still got Elves.

So, yeah, aside from Liches and Vampires who have IC get-out-of-death free cards I don't see why any other races should've been banned if the logic isn't consistent. We have tons of races with origins specifically in Sigrogana yet we got them just fine in Korvara. The Papillion one makes the least sense since Mechanations got banned for being from the same place.
