This was... a really, really good ending. Tied up a lot of lose ends in some very clever ways and let just enough plot dangling for the "breather" patches before the next expansion really kicks in.
Going back to what Venat says about becoming Hydaelyn's heart, but not vanishing from the world and keeping her own form... I think that's what happened with Elidibus too. He's less his own primal and more... an extension of Zodiark on Hydaelyn. Which... suggests a lot about why Zoidark was summoned... to save a world on the brink of ruin. Which... Zoidark did do... just at a very high cost. Only... no one remembers Zoidark, so to still have people worshiping him... Elidibus is at least getting people to hope for the same idea "behind" Zodiark. Only, our character isn't playing by the same rules as other Warriors of Light have which is a huge problem for Elidibus. We've seen him get more and more... desperate... ever since 3.4 when we foiled his plan with the Warriors of Darkness. And it sounds like he snapped when we finally went so far as to call ourselves by a completely new title. It's a sad end, but given what he was doing and how many lives he was messing with, it had to be done.
The fight with "Warrior of Light" is excellent and the number of call backs to other FF games and jobs is crazy. That the "Warrior of Light"'s ultimate attack is "Ultimate Crossover" is the cherry on top. As is what seems like the Ancient soul of Hades showing up to pull all of us out of the Rift.
Speaking of that... our Convocation Title and description is... amazing. Especially in light of something Temulun told us back in Stormblood.
Temulun
[You are] A singular radiance. Shimmering.
Like a jewel of the Dusk Mother, blinding in its brilliance.
Stars flicker and flock to you. Before such gathered light, even the secrets of the gods maybe laid bare.
Some are fated to rise in grace and glory. Others to falter and fade, though not from memory. Both will be your strength and salvation come the end.
Cherish the stars and the light they bring you in the dark.
For you are a traveler, are you not?
It's along very, very similar lines to what is read over the screen (probably in our star/soul crystal) when we summon the other WoLs/teammates to help us take down Elidibus.
Herein I commit the chronicle of the traveler. Shepherd to the stars in the dark.
Thought the world be sundered and our souls set adrift, where you walk, my dearest friend, fate shall surely follow.
For yours is the Fourteenth seat--the seat of Azem.
I find it very amusing that our OP Ancient ability is essentially the most OP teleport in existence (no wonder we never get teleportation fatigue). I don't think it's an accident that Hades' soul showed up on what looks like our Sigil of Power in that fight... not at all...
Watching the Scions say goodby to Novradant was... really emotional. It's amazing to think that from the Scion's point of view, they've been living there anywhere from three to five years. They've all matured in that time and really come into their own. What's also cool is to see that for all the Scions were leaders in their communities, the communities themselves will be able to get on just fine without them. Leading a people out of darkness (or light as the case may be) is one thing. Knowing that if you leave, your hard work will not go to waste is another. And it's clear nothing we did on Novradant will be wasted.
Elidibus not being around does kind of change things up on Zenos and Fandaniel's end. Before... we knew Zenos wanted to go take over Zoidark and then go fight us. But now Zoidak's heart is gone... and who knows how that is going to effect Zoidark. On top of all that, it sounds like no one is guiding the rest of the Asicans. And that could be... really bad in the long run. Like it or not, Lahabrea, Emet-Selch and Elidibus were the powerhouses in the Ascians and they honestly wanted the Source world to stay physically intact. Zenos and Fandaniel really don't care about that. In fact, watching Zenos and Fandaniel bounce off each other is like watching Kefja and Kuja interact in Dissidia. They're powerful enough to wreck the world and simple-minded enough to do so. And now there's no one riding herd on either of them to curtail that tenancy.
However, most x.4 plot don't end up continuing all the way into the next expansion. Wile I can see the fallout of whatever this Zenos and Fandaniel arc will be effecting the next expansion. I doubt Zenos and Fandaniel themselves will be major players in it. We've been wanting to know what Zoidark thinks for ages, and have found oiut that Elidibus is... a part of Zoidark. In effect, it's almost like we've been seeing something of what Zodiark is like since 2.3. I think Zodiark himself will take the main stage sometime before 6.0. How, I don't know, but Zenos wants to mess with Zodiark, and I have a much harder time seeing Zenos controlling Zodiark as opposed to oh... Zodiark controlling Zenos. As much as Zenos annoys me as a character, I can stand putting up with him if it means we get to finally find out what is going on with Zodiark.
