I'm doing the 'Last 100' of the Seventh Astral Era Quests, having seen what happens before the Leviathan fight (The Sauagin gaining the Echo.)

Minfilia says 'This may be how warriors appear to fight the darkness again and again', right?

Well, it made me think: What if the Warriors Of Light are no different from Primals?

What if, when the world is out of whack, Humanity (or what have you; the playable races), praying and crying out for help, shape the Aether and CREATE the Warriors of Light without knowing?

Just an interesting thought that popped into my head.
