Gerun Oracles

[Kotemon]

I'm late to the party; again..

Lets see if I got this right:

The sea = Lifestream

Sun= Hydaelyn

Moon = Zodiark

Fourteen = Astral and Umbral Eras? Makes sense if you think about it.

Children = Some primals. I don't think Bishmark, Moggle and the bug are aware of Hydaelyn like the others. (That needs to be explained after remembering the description by the dragons of what Bahamut and Shiva were). Inversely it could be those who have the Echo and other such direct objects. That seems to be the likely association given Matoyas info about the eye and possible Lore around the Zodiac Braves.

Shiva's summoning appears much like how Terra transforms into an Esper. Perhaps that's the difference between her and Odin to the other summonings.

His Doom = Still possibly not primals but likely the Ascians or possibly whatever the dragon is guarding. Likely a metaphor (or something) like the "goblin train" in XI, not an actual Doom Train.
XIV's version of Pandora's Box?

Void = Empty space between realities. Thanks unknown origin for Gilgamesh.
