[MAJOR SPOILERS] On Souls and the Lifestream

[Alleo]

I honestly wonder if something like the lifestream even existed before the sundering. Seemingly the Ancient ones are of long life and in the face of death and destruction they simply paniced. So if nobody is dieing do they even have a lifestream? What about the creatures they created? Did they die? How was it possible to live forever, yet still give birth to new life? Where did those souls come from? And how did they not manage to overgrow the planet? Or was this the reason the calamity even happened?

I do find your questions interesting OP. In the end Emet hated us for our imperfect souls and also for the cycle of death it created. Yet death was possible with the Ancient ones too..Emet also believes that Zodiark can give back those that sacrificed themselves to him..so does that mean that he kinda has all the souls of these people in him? I wonder if in the end we will free those souls from Zodiark and release them to the livestream so that they too can be reborn again..

Anyway I hope we will get more answers to that.

The question about Souls and the lifestream is an interesting one. I mean I had been thinking about FF7's ending at least direction from one of the devs is that life was better without humanity. I mean would it be that in the end if new souls can't be created the eventual extinction of mankind is in store but the planet lives?

Hm that would only be the case if the old souls are all destroyed but seemingly it does hint that souls continue to exist and become people again just without the memories of their past.
