I should have taken notes the other day when I'd done the first part. I have probably forgotten a couple of things.
THE ENDING
Firstly, a couple of links I meant to share in the 7.3 discussion but misplaced for a while: an interesting
Reddit post from 7.3 that draws some connections that are coming back now. Most relevantly, a connection between Halmarut (associated with plants) and the goddess Demeter, hinted at in 7.3 by the name Demetrius -- so perhaps we can assume that Halmarut has been involved with Preservation for a while. A
separate discussion proposed that the then-mysterious Ascian might have been acting as the simulant Sphene too, rather than that being just a creation of Calyx, in which case for all Halmarut's quirky presentation here, she's already been acting as a competent villain against us.
It's curious that we now have a second example of a "green" Au Ra after Varshahn (though he just had green horns, not scales as well). Can we assume there's a whole clan of them somewhere? Though on the other hand both characters are "fakes" and Halmarut may have just made it look like that because she liked the colour scheme or something.
Halmarut's rambling seems to confirm to me that the term "Winterers" is metaphorical: withdrawing to a safe place to "outlast the great withering to come", indicating that this coming disaster is something temporary to be waited out -- but then that doesn't really seem to add up with the "world doomed to die" talk which suggests a more final destruction. Though maybe if the world dies it rejoins automatically, and that's what the Ascians wanted... but as Fandaniel indicated, the individual remaining Ascians are free of the Ancients' goal now. So what does Halmarut want? And why not approach us to warn us if we're genuinely endangering the world?
RANDOM OBSERVATIONS
They let Sphene be healer for duty support! I hope they fixed that for the Meso Terminal too.
It was cute that G'raha talked about Lyna, but also kind of odd because (once we were told we have to drink the medicine) I was anticipating a different reference back to when Chessamile forced us to take something similar, and I'm pretty sure she said something about having to force the Exarch to take it too. Though I suppose Lyna probably teamed up with her on that front.
Treno character outfits are an odd mix of different styles. Lumull and Eyaney in modern-looking Everseeker gear, but most of the others are in a mix of the new tome sets, Heirloom aiming top, Crested, and (another vibe again) the Mistic mage sets which seemed out of place and Turali-looking among the designs of last patch's dungeon sets and still don't seem like they fit in here. Is it supposed to be from some other FFIX culture? Also interesting that Miyali's costume is the one Historia set that had people saying "why is this here, it's not based on any FFIX character" -- I wonder if it was, at the time, sneaking in a design that they wanted to use for this NPC in the future.
There was a random unnamed character in white and red crafter gear who was playing with a dog on the farm earlier, and then at the end was on the main street apparently searching for a dodo, while down by the canal there was another character with a dodo. It could all just be a simple "the farm animals ran away when the monsters invaded the field" thing, but it seems like it could be a reference to something else.
