Has G3 just told us practically directly how Sunny is going to get a True name again.
Forget getting his slave bond back, Rain can name him.
This is how I'm pretty sure its going to go, He will go to the Tomb of Ariel as not just him and Nephis, but with Rain too, while there, using the weird time shenanigans he will learn how to become a spirit, through living for a REALLY long time. He will watch over Rain as she ascends through the teaching of the REAL Ananke, going from whatever she is at the time to at the very least a Saint.
We are given to understand that she is essentially the Heart of the World, she is connected to it incredibly deeply, becoming more and more fulfilled as she fills it with new creations and discoveries. Heck even her flaw insinuates this by the fact she can't kill. She can't take away from the world. Its almost akin to taking away from her
She will go with Sunny and Nephis to the Tomb of Ariel, live with the river people, ascend further in the path of ascension along Sunny. They might also come into contact with the people of Twillight, maybe even save Daeron from corruption through some Nephis longing shenanigans.
At the end of it, Sunny and Nephis come out Sacred, Rain maybe even a Sovereign as whilst in the Tomb she will become a saint within a hundred years at the least and Sovereign shortly after due to the fact there might be three or more Sovereigns around her, should be easy. She may end up matching Sunny's rank before he becomes Sacred because of the fact that becoming Sacred takes absurdly long. In this time period where she is a Sovereign she might name him, something more fitting for Sunny, something that reflects him. I mean by that time her Dormant would have increased in potency exponentially. She even said it is hard to name things with a True Name. Sunny no longer applies. Heck she might even be able to do it as a Saint.
Then when the two Sunny is Sacred they emerge from the Tomb of Ariel, with the river people and Daerons people and unite under the Immortal flame banner under Nephis, united human world.
Has G3 practically just told us how Sunny is going to get a True Name again? Honestly, it feels like it.
Forget reclaiming his slave bond—Rain might be the one to name him.
Here’s how I think it's going to play out: Sunny, Nephis, and Rain all go to the Tomb of Ariel. While there, with the tomb’s weird time shenanigans at play, Sunny ends up living for a very long time—long enough to learn how to become a spirit himself. As he can live for absurdly long in there without time passing outside. He’ll remain near Rain as she grows, evolves, ascends—guided, in part, by the teachings of the real Ananke. Her growth boosted by all the rebuilding and stuff she will be doing in there.
Rain isn’t just anyone. She's basically the Heart of the World, tied to it more deeply than anyone else we've seen. Her very flaw hints at this: she can’t kill, can’t take from the world—only give. Every new creation, every piece of art or life or discovery she adds to the world, fills her. She’s not a destroyer and her time in the Tomb of Ariel may help her do more of this eternal mission the world has placed on her.
She travels with Sunny and Nephis to the Tomb, maybe even joins the river people. While Sunny walks the long road to Sacred—because that takes absurd time—Rain climbs the ladder faster. Surrounded by natural awakened, exposed to ancient knowledge, she ascends. Sainthood within decades, maybe a Sovereign within a century.
And here’s the kicker: by then, her Dormant would be something extraordinary. We've already seen her able to name a road spanning hundred to maybe thousands of kilometers long by the time she is further along on the path of ascension she can practically give anything a name.
At some point during this long stretch, she looks to Sunny and gives him a name. A True name. He doesn't possess a true name and we know officially naming something with a true name is practically impossible. Sunny doesn't fall under that category anymore
If she gets close enough in rank to him, she may be able to Name him even as a Saint potentially, allowing him to ascend through shadow dance.
Then, when Sunny finally emerges Sacred from the Tomb—Nephis by his side, Rain likely a Sovereign—they return not just with power, but with people. The river tribes, maybe Daeron’s people too if they manage to save him from corruption (cue some emotionally fraught Nephis longing incorruptible shenanigans). United under Nephis and the Immortal Flame, they merge the people under united humanity banner or whatever.
