Goodbye to my joke hypothesis that Chirex is Ganelon’s birth mother; you had a good run. I figured that since both were failures, and Chirex has been around Rim Square…
Well played… can’t say if this is concealing meaningful information or a troll about how secret the Kryptasts are. But I’m keeping my eyes peeled, especially once it comes time to scheme and plot and watch out for Kryptasts in Grand Shayard 
A couple follow-ups…
One detail that struck me as odd was what Cerlota calls M’kyar the very first time they meet:
“Seracca sa’vewa!” Cerlota calls frantically from over your shoulder. “Peace, daughter of the plains!”
The game draws parallels between the Seracca and the Old Brauracha, before the Storms:
“So your folk see freedom differently than the Xaos-folk.”
"The Seracca care for our weak and wounded, and always have. But then, so did the Brauracha nomads who roamed these Lands before the Storms came—or so said my mentor, whose own mentor still recalled their ways." M’kyar’s eyes are luminous on yours. "The people of Braurach were always great mockers, but in those times their mockery was saved for anyone especially strong or skilled. Anyone who might set their sights on becoming a tyrant."
“Each other,” M’kyar says briefly. "Every Yega’a came together to cast down a would-be tyrant. Since then, none has tried to impose a Hegemony on us."
And even with the nomad phyles of today believing in the protection of an animal guardian spirit from “time beyond mind”: Red Kestrel, Whiskered Hawk, Blood Raven, Shard Owl.
So there are narrative parallels between the Seracca and the plainsfolk… but the way Seracca lands are described, it’s as jungle — even by Cerlota herself:
“If you are prepared to live like beasts, roaming the deserts and jungles in small bands!
Leaving the question of what led Cerlota to address M’kyar in that particular way? (And for it to work?)
(And since I’m laying all this out already, I’ll add that I’ve been looking at this question from the perspective of one fun line from M’kyar)
"Learning and discourse, traditions of change and continuing, that go back eighteen hundred years. We have built cities, and abandoned them, and built them again."
While it’s not concrete enough to reliably reason on, Jev’s recollection of the Brauracha origin myth did cause a tiny blip in my head about this.
We tell stories about Brurq the Kinslayer; when he was cast out of Nyrnakan for his crimes, he took a gang of bandits with him into the wastes. They kept going right round the Wiendish mountains
Since geographically, Kylik (and Torane) mention that the chasm-forests and mountains of the northwest are the outer limits of the Unquiet Dead’s territory: places it seems likely Brurq and his bandits would have passed through in legend (and the Brauracha migration could’ve anyway). So one, hearing both of those details, might wonder whether or not the Unquiet Dead fit into that story, and what that would mean.
Agerain survived, eventually became a full-fledged NPC in the party of escaped slaves, served as a romantic antagonist rather than a murderous one, and ended up getting a measure of redemption.
Agerain d’Aramant of all people became a romantic antagonist… that’s the biggest shock related to that story I’ve had since seeing the words “Red Kestrel” show up.
I’m inclined to agree, because the path to immortality seems paved with rivers of blood. The Seracca, with their immense understanding of the human body, can only stretch it out a few centuries — incredible, but still unable to overturn the fundamental property of death. Maybe some synthesis of Seracca ways, Archlich Ghaesh, whatever Kleitos is busy thinking about, and Talismans could produce some miracle, but I’m not holding my breath.
It originates here.
