First off, I have that nice post a page or so back that has some Unukalhai dialogue that defends the fact that he's very much not a normal child. Why would a child be our enemy at any given time? Urianger's line is "he's not our enemy - for now." Also, he has no fear of tempering and goes right up to Sephirot with Krile, which she calls him out on - remember, Lahabrea implies Ascians have the Echo in the ARF, and we all remember Elidibus' demonstration in 2.2 about the hidden capabilities of the Echo. Either he's tempered by another primal, which would be quite strange if he was helping us at all in that case, or he is in possession of the Echo. We can state this factually, because the game tells us it in the dialogue. He is not afraid of being tempered.
If you're unfamiliar with his name itself, Unukalhai is the alpha serpentis, one of the two sides of the serpent that are held by the Serpent Bearer, Ophiuchus. As the Ascian names and numbers - eg, Lahabrea corresponds to the 12th - are very much ripped directly from Ivalice, that leaves Zodiark as the 13th, representing Ophiuchus. So there's our direct connection, it's being shoved pretty blatantly in our faces. This is where
totally-not-Elidibus-or-his-servant comes into play; the name easily implies he could be Elidibus, or a simple Lesser Ascian follower of Elidibus, as he says he is.
The master-servant relationship in most lines from Unukalhai clears up nothing on if it's Elidibus or a Lesser Ascian. A Lesser Ascian is a servant to his/her Ascian Overlord master; an Overlord is a servant to Zodiark. It's not terribly different from those who
serve Hydaelyn, like us, on the Overlords' parts, so don't take it too literally. From what we've seen. Lesser Ascians more directly a serve their Overlord than Zodiark, going about more mundane duties, such as empowering the beast tribes and gifting them the ability to summon primals as we've seen demonstrated in the 2.X Extreme primal series, while the Overlord does other things.
We do know, factually, that Elidibus mentions he wants to Triad dealt with from his quote at the end of 3.1:
Our fates were ordained long ago, Archon. The Garleans are no exception. Nor the Triad. You know what must be done.
After this line in 3.1, if you speak with Urianger in the Sands, he mentions that, even though he knows now that the world is destined to head towards a terrible fate without interference, it is still within their ability to fight it, as if Elidibus is directly showing him how he can do so.
Urianger is seen in 3.2 helping us with Unukalhai's quests, which is quite odd, considering he almost never comes to us directly on primal quests. I'm personally of the belief that now that he is seeing the truth in Elidibus' words.
To further evidence that it's Elidibus involved, remember, in 3.0, the only time we see Elidibus is during the epilogue. What does he say? He needs to clean up after Lahabrea and Igeyorhm. What was the mess that Lahabrea and Igeyorhm left?
Thordan attempting to awaken the Triad, hence why he was in the ARF, that's where the Triad core is.
Please note here that I am not making any judgments on
why Elidibus wants the Triad dealt with and removed from the picture, that's another theory and not really related to
who Unukalhai is, but Elidibus does for some reason or the other. I have my theories that I've posted everywhere, this post is not about that.
Finally, I'm not sure if they changed this when they changed the Ravana and Bismarck quests in 3.1 because I finished them in 3.0, but in order to fight against them again, Unukalhai gifts you items that are relics so ancient even the
tribes themselves didn't even know they still existed. Where is a Spoken, let alone a child, going to find such items, let alone know what they are and can be used for?
So. If I've not at least convinced you he's either an Ascian or directly related to them I don't think anything can and you're probably going to be ignoring the evidence that's piling up in search of an undefended alternative.
The issue from there then, is he Elidibus? Is he a Lesser Ascian? Or is he just an Echo user in the service of Elidibus?
I believe it's possible to rule out the last simply because he appears to us as a child. If he appeared to us as an adult, we could not. You'll notice when he speaks to Regula, it's demeaning, not in the sense that Unukalhai is arrogant, but in the sense that he does not view an adult in the way a child views an adult. Krile also notes he's incredibly serene, to the point that no child is. Serenity is almost never an adjective that anyone applies to children of Unukalhai's [host's] age.
There's further evidence of this when you speak with Unukalhai again after the 3.2 Sephirot quest set. He notes that Y'shtola can see changes in aether and hence why it may lead to distrust about who he is. But as far as we know, we've no evidence that Y'shtola can sense an Echo user from a normal individual simply based upon their 'aura.' What she
can probably sense is an Ascian in a host due to the way the internal aether flow is (likely) changed.
From there, it's either Elidibus using a child's body, or a separate lesser Ascian using the corpse of a child, because from the SMN questline, lessers can only inhabit corpses.
Personality-wise, building from the serenity comment, you'll notice Unukalhai layers praise on you quite frequently, buttering you up, so to speak. This is very similar to what Elidibus does in 2.1. Elidibus is an Emissary, it's his duty to smooth over negotiations with diplomacy; it makes sense that Unukalhai, as either Elidibus himself or his servant, would share these same traits.
My crackpot is that the Lesser Ascian servant takes on traits of the master, given how all of Lahabrea's servants have a very distinct personality similar to Lahabrea's, where Unukalhai has a personality more similar to Elidibus. I've no real evidence beyond that, though, hence being crackpot, which is something I indulge in quite frequently.
So. Why do I believe he's a Lesser Ascian and not Elidibus? Simply because I'm inclined to trust Unukalhai is who he says he is. He says he serves
a friend. Zodiark is not your friend. However, in your shared goal of ridding Eorzea of the Triad, Elidibus is. For now - as Urianger puts it.
Now, on to Krile's assessment:
The first thing you'll notice when you see the dialogue is that
Krile assumes she is right. Unukalhai doesn't really confirm or deny anything. She can't even see his features, so maybe there was something intended in the dialogue that implies it, but all he basically says in return is "Is that so.?"
Her assumption lines:
Quote:
Just what are you hiding beneath that mask of yours? Hmmm... A longing for hope. An appetite for power. A lingering sense of regret.
And do I detect a desire to test your strength against a certain hero...?
His response?
...Is that what your gifts tell you?
Can we draw assumptions from that? I'm not sure. I wouldn't risk it, because it's easy enough to twist.
As I said, it may be that he doesn't
want to challenge the Warrior of Light, he simply expects he must.
A longing for hope? Regret? These are extremely vague and could describe literally any character in the game. Including ours. And the search for power is not necessarily a bad thing in and of itself, after all, we do it in every class quest from 30-60. In my opinion, Krile isn't very good at judging personalities, she could very much be describing our character or, say, Thancred, with those same adjectives.
The interesting thing about this scene is that we have Unukalhai's point of view with Regula, rather than ours. So when he makes a comment regarding the Garleans, it's like 'yeah, he's totally right, they're going to interfere!' -but then you forget that no one else, including your character, saw Regula there, which made everyone distrustful of Unukalhai when they didn't need to be. We saw what he saw, we know he's speaking the truth regarding the Garleans. But to the Scions? That's an almost unnatural form of precognition. I just thought this was an neat form of storytelling.
But I digress.
Who do I think Unukalhai is?
Well, as I said, I'm of the belief that Echo users can ascend to Lesser Ascians under the right circumstances with a proper catalyst, of which we know nothing about, due to the cutscene with the Sahagin Elder and particular dialogue in the level 60 SMN quest.
So I believe that at one point he was a mortal Echo user and he
did fail at his purpose, which ended in his death. But in doing so, became an Ascian. Does he want to be an Ascian? We don't know; they may be unwilling thralls that serve their Overlord. Lesser Ascians are so interesting and I'd absolutely love more information on them sooner rather than later.
All I can say with a certainty at this point is that Cutest Ascian is shaping up to be our sympathetic Ascian that may give us some moral grey areas with them regarding our character. And that's exactly what I've wanted from the beginning when Elidibus was introduced.
