I have a slightly related question from the end.

So in phase 2 and the cutscene after it seems Emet draws strength from the prayers and hopes of his people. But....shouldn't those people be fragmented across the different shards/source? Not hanging around in the darkness with Emet? And if they're the souls offered up to Zodiark shouldn't they be sealed away with Zodiark? Where exactly are they coming from?
