X references that come to mind – the whole concept of Sin has some commonalities with Zodiark, with Yu Yevon and the many willing people of the city who became fayth summoning a form of salvation, becoming the core of the first Sin; I believe there is a difference, though, in that Elidibus was able to remain in place as the core, to the point that he could withdraw himself to go assist in the conflict raging on the world itself, and obviously Zodiark did not fabricate a dream world but repaired the existing laws of reality. Rather, what went wrong was the dispute between each side about the restoration of the sacrificed sleeping within Zodiark (I posted about that
here.) However, it is entirely possible that Zodiark, dormant as he is now with many souls slumbering inside him, has created some manner of dream Amaurot inside him.
Although I do not think the conflict really touched on the Sound, it is possible that once Hydaelyn and Zodiark unified and she enervated him to create some manner of balance/new order, the sound re-emerged, and this is when Zodiark, lacking his core, was taken over. There’s parallels between Venat’s act of fight with Zodiark and Lady Yunalesca and her battle with Sin, leading to her death, and in Venat’s case, the Sundering.
As well as the visual parallel with the pyreflies, and also Lady Yunalesca’s hair and body, and Hydaelyn’s in the Amano art. There is a similarity here between how, once a Final Aeon defeats Sin, it simply becomes it, with Yu Yevon possessing it, so to me Sin is also comparable to the Sound itself potentially, assuming it can take over whichever Primal defeats it – maybe a coreless one. With Zenos’s plan to draw on Zodiark’s power for his “ultimate” fight, and embodying many of the cardinal sins, there is that too.
I also think Lady Yunalesca has similarities in her genuine conviction with both sides of tempered – the Ascians and the restoration of the ancient world, and Hydaelyn and her summoners’ belief that the world had to be ceded to the newer life forms, and I hope/expect that will re-surface with Venat later on should the theme of remembrance come up, since as per Elidibus’s epilogue, she and her summoner’s both intended for memory of the ancient world to fade.
My hope is that they stick to their word of this being a conflict of two perspectives, and the way they have kept Azem withdrawn from either side, and don’t just have it conveniently be the case that they last minute sided with her, and that there was a good reason as to why Azem did not. Possibly even balking at the sheer scale of the conflict and abdicating their responsibilities, leading to a worse overall conclusion than if they had stepped in; something along
these lines. I still reckon Elidibus, who was close to Azem, being chosen as the one to be the heart weighed heavily on them, much like Yuna’s potential demise as summoner did on Tidus. As with Tidus, will Venat may be gone once her own singular purpose is fulfilled? Or, as Yunalesca, will she consider it a fight that cannot be ended in that way?
There is also a parallel with Yuna and defying Lady Yunalesca, and Venat’s “put a break on this future”, but where I believe they differ is that, as with XII’s Venat and CT’s Schala, this led to unintended (? In Venat’s case) consequences – i.e. the Sundering, lending her a more tragic aspect.
I see more of Yuna in the MC, especially with how events between 5.0 and 5.3 have re-shaped their perception of the whole conflict of light and dark, with the conclusion, IMO, being that they will be the hand by which to end this conflict, much as with the Dragonsong War, with which there are many parallels. Plus her conviction that she could rout Sin even without the Final Summoning. And with Braska there’s some similarities to what we see in Azem, from what little we know of them, mostly based on Ere our Curtain Falls and Hythlodaeus’s dialogue in 5.3.
With Seymour, there’s a bit of him in both Zenos and Fandaniel. His obsession with the WOL/D (Seymour’s infatuation with Yuna, as well as protecting her from Sin, mirroring what may happen in EW), the sense of loneliness (in Zenos’, his desire to become Sin, the patricide of Jyscal (a stern father like Varis, who – one could say rightly - viewed his son as an abomination), these remind me of Zenos.
I see Vayne, Sephiroth and Seymour in Zenos, and Kuja, Kefka and Seymour in Fandaniel.
His nihilistic stance (“Your hope ends here! And your meaningless existence with it!”) on the other hand, reminds me of Fandaniel – his defiant attitude to his masters (the three unsundered) and nihilistic attitude also are reminiscent of Kuja and Garland from FFIX. Not to mention, we’ve no real idea what his role was in the ancient world, since he may well not even be the original incumbent of his seat. Venat’s vanishing from the world is similar to Seymour’s mother’s, as well, so in addition to the nominal XII connection, perhaps there is another.
You could easily see Seymour Omnis as a basis for Zenos drawing on one of the two Primals:
And the Mortibody as his travelling companion, should he have one as a Reaper.
The whole build up, with Thancred remarking on the point soon being reached where we’ll see the end of primals, Zenos’s desired big fight drawing on the two primals and the possibility of reckoning with what caused the Final Days, all have parallels to the Final Summoning.
Meanwhile, Garlemald has some elements of (ancient) Bevelle to it, like Vegnanun, an indiscriminate weapon much like the Black Rose. You also see elements of it in their history of being persecuted, due to an inability to manipulate aether, leading them to focus on mechanical ingenuity, similarly to the Al Bhed. But I think we may also see aspects of its later incarnation in Sharlayan, with its rigid orthodoxy, and possibly its belief it is acting in the way either the gods it follows (similarly to how Yunalesca played along because Yevon’s philosophy aligned with her own), or what it knows of Amaurot, would consider desirable. Things seen as well through the faith of Yevon. Sharlayan is, in some ways, a twist on Amaurot’s ideals and method of governance, taking a much more isolationist stance, compared to that ancient city, which sought to be an example for others to emulate and which guided the rest of the star. As a city, it also engineered an entrance to the equivalent of the Farplane, the Aetherial Sea, via the Antitower.
The symbol of the Scions of the Seventh Dawn, similar in nature to Yu Yevon’s sigil, shown in that order:
The centre resembles Azem’s soul crystal (the symbol recurs a lot) and, with a bit of rearranging of the Archon sigil, we can see the sides the wings of the two eldest primals.
With Zanarkand, we have this similarity to the Convocation and its offices: “Summoners took the name of a "god" and once they died or became an unsent, they gave up that name, reverting to their original name with another succeeding the god's name.”
Lastly, with Yoshi drawing attention to the number of times Hydaelyn has spoken to the MC, and that being a focal point of 5.5 part 1 (where Y’shtola asked about direct contact), it leads me to think they may be referencing it from a Chambers of Fayth pilgrimage angle, especially since the upcoming expansion may well spell the end of Primal summoning, as well as the final arc in the battle between Hydaelyn and Zodiark.
