"Who, WHAT are you?" *main story spoilers*

The more I think of it, the more it seems to me that SE are using a similar idea from Dissidia here (the first one, not Duodecium which just had an excuse plot and the non-existent plot of the recent arcade version), where like Cosmos placing a portion of Her life into the crystals that her 'champions' recover, knowing that it would weaken Herself fatally, something the antagonists would be quick to exploit, in much the same way, what if the Crystals of Light have actually been infused directly with Hydaelyn's power, which is actually what has weakened Herself to empower us instead?

And that, like Cosmos, ultimately it would result in Hydaelyn''s physical 'death' knowing that the Ascians and by extension, Zodiark, would not waste time in trying to eliminate her... but, as her life continues to 'live on' within the Crystals and by extension, through us as her champion, allowing Her to finally destroy Zodiark and the Ascians for good and end the cycles of Umbral and Astral forever? Note the similar terms here: 'champion', 'crystals infused with the goddess's light', 'goddess of Light and god of darkness', 'Cycles of war/destruction/death/darkness and peace/rebuilding/life/light'. Making this whole thing one giant Batman Gambit on the part of Hydaelyn.

Of course there are major differences, but the themes are remarkably similar. Or at least, that's how it seems to me anyway.
