Sundering and specific character questions. [Spoilers]

[Theozilla]

If there was a pre-existing moon/celestial satellite prior to the Sundering/Zodiark’s banishment to the heavens, and it was more akin to Zodiark was sealed inside/fused with the moon, maybe that’s what gave the Ascians the idea to give the Allagans the idea to put Primal Bahamut into Dalamud?

I believe I found the interview MikkoAkure may have been referring to?

And Koji only says that the Sundering/“splitting” was focused on the planet Hydaelyn. He actually says how far the split extends is something that he still needs to confirm with Oda-san. So it seems like it wasn’t fully confirmed then.

So perhaps maybe the Sundering only sundered the souls the Planet/Source, but the other planets instead essentially got “copied” into the dimensions of the 13 shards, but they aren’t “diminished” soul-wise like the Hydaelyn shard planet inhabitants. So there could be a Migardsormr in the universe of the First, who is also unsundered, but just never came to the First?
