You know, I think it's deeper than merely being the Ascians and/or the Primals.

This is a very left-field stretch, but... what if it's meant to be the Allagans and maybe--just maybe--the Warriors of Darkness?

I'm just throwing it out there. The fact that the adventurers from 1.0 are all considered the Warriors of Light, and the fact that the Crystal Tower exists, and yet... there are absolutely no mentions anywhere about the Warriors of Darkness. Not once anywhere in FFXIV lore. Which, especially with the introduction of the Crystal Tower, seems extremely baffling to me.

Now, the Warriors of Darkness are not meant to be "Evil", mind you. They're just meant to be folks who, much like the Warriors of Light fight off the forces of darkness to prevent them from swallowing the world, the Warriors of Darkness once fought off the forces of light to prevent them from swallowing the world, both trying, albeit ignorant of their true purpose, to keep the world in balance.
