The next Dual Element Primals? (Spoiler)

[Rocl]

I honestly understood it as the new summoning of Ravana / Bismarck (i.e. the extreme versions) weren't Ascian orchestrated (the Ascians didn't step down and say hey guess what happens if you use a sacrifice and carve up their bones!?). Whether I believe that, well no, I don't.

The translation of Tharl Oom Kash is fairly straightforward since it's in the sightseeing log: "Crystal from remorse"

The idea of each of Midgardsormr's brood harboring a specific element is nice but assigning Nidhogg strictly Fire is probably wrong. The Aery, like Tharl Oom Kash, seems to be primarily Lightning-aspected and the weather when you enter Nidhogg An even changes to Thunder. That said, Massacre and the Scarlet Price certainly seem fire-based, but what of the Sable Price? (Also worth noting our meeting with Tiamat lights the Crystal of Fire, and I'm fairly sure Nidhogg's defeat awakens the Crystal of Lightning)

We've been more or less kept in the dark about how much the celestial wyrms know about anything (though it is reasonable to assume they know nearly everything). There are so many questions about why the wyrms didn't tell us more or deliberately kept things from us. Why the hell didn't Midgardsormr tell us about Azys Lla or Tiamat or what was kept there? I mean yeah yeah "testing us" but we're all after the same foe here, yeah? If they knew of Tiamat and Bahamut's fates why were Hraesvelgr/Ratatoskr/Nidhogg buddy buddy with proto-Ishgard? I feel like the falling out between man and dragon should've been way earlier.

All that said.... I vote Syldra. We already know she exists as a sea serpent in Eorzea's mythology!
