Something similar to XI's creation mythos in that somehow Zodiark was used in the creation of life is definitely my hypothesis (or one of them), I just wanted to keep my XI theorizing out of it and went more factual.
As it seems now, Hydaelyn has sole dominion over "the Source," which is what Zodiark wishes to re-establish contact with - or so we're told. But why would Hydaelyn's control over the source allow for the creation of life in and of itself? Either we don't know enough about this "Source" or there's something else to the story we don't understand yet. I'm going to eat my non-existent hat if it's not the latter.
