Gerun Oracles

[Cilia]

This sounds like it's almost confirming one of my hypotheses: that Zodiark IS THE MOON.

Yes, you heard me. And I guessed this even before it was pointed out there's what's likely a ruined version of the Zodiark statue up there.

"There was but the sea."
Long long ago, in a galaxy far far away... just kidding. The Aetherial Sea, most likely.

"Light and Dark were divided, the sea sundered in fourteen."
This lends credence to the popular hypothesis that the Ascians may be the "original" gods the Twelve are based on. Either way, it's likely the origin of the Ascians in some way or another.

"To the seas She cast Her children, for fear of the Moon.
"For hate of the Star, to the seas He cast His doom."
Hydaelyn created the planet we live on as a shelter from Zodiark's ire, while his hatred towards Hydaelyn leads him to continually try to destroy the planet (or he already has, it's just a matter of time).

Those are my thoughts and best guesses on this one...
