all of the stuff I've said about the WoL's suffering and dehumanization as a result of being chosen as Hydaelyn's champion, but also the fact that Venat does truly, deeply care about them.
Everything you've gone through, good and bad alike, does serve a higher purpose. But She didn't choose you just to forge you into a living weapon, but to make a perfect counterargument against the Endsinger's nihilism, against despair itself. You are the answer.
Shadowbringers is a ghost story, it's a love story, it's a post-apocalyptic horror story, it's a high fantasy that turns the genre's notions of light and dark and hero and villain inside-out and upside-down. Fitting with the whole light and dark schema it's FF14's writing at it's darkest and edgiest, and most optimistic and hopeful at the same time. It's about the struggle of finding and protecting whatever hope you can in the most painful of situations, about how even the strongest of us have to rely on one another, and it's an allegory about healing from grief and trauma on a grand scale. It's about choosing an imperfect present, a broken world, over a false promise of a utopian past.
Most importantly it's a story about the universal human experience of trying to kill evil angels while being lied to by wizards who are weirdly obsessed with you.
I personally think Y'shtola deserves some more credit for how she advocates for the Warrior of Light during Shadowbringers. Without knowing the whole story I've always felt she had every right to be uneasy with the Exarch, and to be honest I was expecting a pricklier welcome from her in Rak'tika... but as soon as she realizes who it is, her greeting for the WoL is incredibly warm. I love that her first question is "How are you?" She cares about them! And when her aethersight gives her reason to believe the WoL is in danger, she's concerned! She thinks they need to be told! And when Urianger won't agree to tell them, she does it herself, because she thinks it's the right thing to do. She treats the Warrior of Light like a person who deserves to know what they're getting into and make an informed decision, and it's such a far cry from the "You'll do it because you're the Warrior of Light!" attitudes of everyone in ARR.
And I think it's also worth noting that in the end, after she knows the whole truth, she doesn't seem to hold any of it against G'raha. When you're back in the Source, she's talking about whether he should be given the title of Nunh after his long tenure as the Crystal Exarch, and after he joins the Scions, she seems cool with him, so I genuinely have no reason to think she holds a grudge about any of it.
She was, ultimately, concerned and wanted to do the right thing, and she cares about the Warrior of Light and their wellbeing, and I think that's an important thing about her.
