And so -
(says one small fragment of Nethys to the gods, borrowing sanity for it from His other fragments bending his will to say it)
- and so, compared to the baseline consequences of Nethys's null action, Keltham has been brought, now, to this pass, less hostile to Asmodeus. Still kinda pissed, obviously, but in a way where gods can negotiate about that; where Keltham would rather offer Asmodeus something He wants than burn Him to ash at any cost. Carissa Sevar has done everything she can to moderate Keltham's demands, and in many cases succeeded.
This is the nice friendly favor that Nethys has done practically everyone including Pharasma and Asmodeus! Really, it's about as much as Nethys possibly could help Them all without giving up the tiniest bit of Nethys's own interests!
...also Carissa Sevar sold her Wishes to Keltham more knowingly than ever before; Carissa guessed more and Keltham told this Carissa more, before he bought her Wishes, than in any previous iteration. Hopefully Pharasma doesn't destroy the universe about that! Nethys thinks She oughtn't to, based on His having watched Carissa Sevar's mind the whole time, but this part hasn't happened before. Anyways that part was definitely an accident and Nethys did not mean to do it on purpose; it endangers His own interests too.
