Reborn was a simple generalization, yes dragons and omega flew to etherys. But they found a new home there and live there now. I still theory that all the other civilizations found some way to appear on Etherys once their own words died. Ea are moogles now in my theory. The way their heads keep popping off just makes the perfect poms. Their bodies remember their former shape even if they do not.

Yes if you want to just talk about the real world recycled/reskined 3D models means nothing lore wise. Its just a cost saving bla bla bla...

This is lore and imagination and story. I still hold to my theory as it has interesting ramifications until something something official is released to say otherwise. Im certain game devs randomly read about what us normal people post and may even get ideas from what is said. My creativity is sparked thinking about possibilities and sharing that may spark something back to the devs... or they just may laugh at me, either way a positive result.
