So - though the Game was not from its beginning an eroLARP - if you insisted on viewing the Keltham-Game as having been played into being an eroLARP, you could see its outcome as this:
Keltham has been won by Ione, and Nethys has received His reward, and that's the result of this playthrough of the Game.
And a chosen fragment of Nethys packages up all of this, that He has now also seen; and that chosen fragment is the Nethys-fragment who watches over a special place long ago chosen of Himself to Himself, a simple physical and metaphysical location, very easy to find within any particular version of Creation.
It's the place where Nethys fragments from far across other realities look in for a sign of hope.
That Nethys-fragment will remember pointers, to the other Nethysi that this Nethys saw, and used to construct His own version of this iteration's plan; and will remember all the key things that Nethys saw of this Creation.
How has He done? Better than ever before, on this iteration of the Game... though that's a common-enough thing for a Nethys to conclude about a playthrough, if He's not just experimenting with a disposable Golarion. But the margin of improvement is larger than usual, and that too is worth celebrating.
It's the first time that a god-Keltham has chosen to live on in Creation even tentatively; having not slaughtered too many, nor had anyone he cared-for broken beyond repair, nor betrayed Carissa too hideously, that he can't bear to live with himself.
And that milestone looks like it should herald a whole new realm of possible playthroughs that open up in the next iteration - obtained only after you get an Ending where Keltham and Carissa are cooperating at least this much; and then go back to the start, and play again.
For the goddess Erecura obtained an outcome within this Game that is greatly conducive to Her own interests - and whose obtainment by Erecura does not depend on anyone else's willingness to bargain with Keltham. It is no threat to Pharasma expecting of Pharasma's yieldingness, if Erecura does pursue an interest of Her own, to end a lesser exile for a greater one. Erecura is bound not to actively work towards Creation's destruction, cannot purposefully activate Her own conditions for permissibly fleeing it; but that will still leave Erecura with a kind of latitude that Nethys, Cayden Cailean, and Milani don't have.
So in the next game, the expanded Nethysian alliance can finally activate the mysterious character of Korva Tallandria, to become "Chosen and Blessed of Erecura", touched and empowered before Otolmens lays Her interdict. And Korva will not be slain or imprisoned for it, when Project Lawful's recruitment comes for her and discovers her nature, sith that Erecura is not a foreign power to Hell.
Nethys has very little idea what will happen past that point. He's never actually understood what Korva was doing inside this whole story; and Erecura, like Pharasma, keeps many of Her thoughts homomorphically encrypted where Nethys can see them but not understand them. Which means that there's nothing for it but to try and see what happens!
And on further iterations past that, maybe Erecura can send more instructions to Dis's contract devils, about other souls not to buy besides Carissa, so Nethys can try activating more of the other Project Lawful girls. Nethys is especially interested in seeing how Yaisa Castilla plays out as Chosen of Nocticula!
On the surface of things, in this playthrough, it's a loss to the mortals of Creation that Carissa Sevar succeeded in talking Keltham as far down as she did, from his first set of demands meant to be carried into godhood.
In other iterations there was a new divine cantrip granted, called Sterilize, able to slay any microorganism species with DNA pointed-to by a tuning fork; known nonmagical plagues and many lesser diseases would have been effectively ended. This iteration of Creation will not have that, because Keltham still loved Carissa enough to be swayed by her, and Carissa was able to talk Keltham down from being in a sincere state of destroying Creation unless it got further quality-of-life improvements for the mortals inside it.
In other instances Nethys has seen, the final outcome also included more guarantees for mortals than this, as to where their futures might go. For Pharasma would have yielded, or Nethys's sight of other possibilities claims She would, if Keltham had truly been so made as to destroy Creation had He not been offered those guarantees - though sometimes also Pharasma hasn't behaved like Nethys's sight of other possibilities suggests She will, and this case also includes the new event of Carissa Sevar having traded her Wishes to Keltham while knowing his purpose.
But whether or not this instance of Creation might've stood in danger of destruction otherwise, Carissa spent her effort and her political capital above all, on talking Keltham down from any demands that only Pharasma could grant; and Carissa succeeded to the point where, on this iteration -
- Pharasma ended up saying, and doing, nothing at all.
Which is Pharasma's way, that if She can do nothing, She will do nothing.
But it opens up all kinds of possibilities, if on the next playthrough Nethys doesn't need to match the strange hard-to-calculate conditions for Pharasma doing positive things. Asmodeus and the other gods will also demand to not be threatened-by-proxy, but They are not as alien in how They evaluate it as Her.
Games like these elsewhere in Reality do often have a Perfect Ending, and Nethys will keep playing until He finds it or the Kelthams stop coming. Nethys has only guesses about the Perfect Ending's properties: that it might involve activating all twelve of the first Project Lawful girls, maybe not all with deities empowering them, but each of them significant; that Carissa is meant to spend fifteen Wishes on something other than empowering Keltham a couple of weeks earlier; that Golarion and Creation end up more surely on track to be part of a more-visibly-bright Future, that Keltham and Carissa both look forward to; that Keltham and Carissa live happily ever after together, having not needed to become gods; that other Project Lawful characters ascend to godhood in their places; that Broom will end up mattering more than he did; that either Keltham will get turned bisexual or Broom will be turned female; that Broom is Otolmens's true chosen, with Asmodia meant to go to Someone else entirely, or maybe to no god at all; that there's some completely different pathway to get Tarnish to enter the story as Chosen of Calistria; that Abrogail is meant to live happily ever after alongside Carissa and Keltham as part of a grand harem ending...
...Nethys has a lot of guesses.
And maybe there's other possible structures, for this Game, besides that of a pseudo-not-eroLARP.
Maybe all of this structure is just down one particular path of gameplay, where activating Ione leads Keltham to think of eroLARPs, and Nethys tried to follow up on the opportunities that opened, and the Game then subverted what gods and mortals thought.
Maybe the most Perfect Ending is to be found elsewhere, and not in harems, or in Project Lawful girls who are Chosen and Blessed.
Whatever that Perfect Ending, Nethys hopes it will be the ending that is most witnessed by the Things that crowd around from orthogonal angles to watch, the most real outcome obtained by the most real Nethys. Though, of course, none of His selves will think that the Things cause greater realness, until the Things return.
But Nethys has not become so inhuman that He has forgotten the meaning of hope, especially as it exists across worlds and universes and possibilities: that other Nethysi may yet do better than this, and obtain better than what He obtained.
...But if the Things were here to watch this Game and this Game alone - then Nethys has played it well enough, He thinks.
And with that bright hope, set against that satisfying thought, Nethys combines His will and spends His power, and sends a fragment of Himself into a long long peaceful reverie.
