Interesting the gods would keep the humans around after such an act of rebellion. What with 5 other free peoples to act through.
And with Karophet being a lawful evil fiend god. Does that mean you use a different structure to the Hells than D&D's Great wheel does?
Somewhat. I don't have any infinite sized planes in the cosmology, because infinite sized planes only make sense for an infinite number of prime material planes and my little multiverse is self-contained. I experimented for a while with infinite cosmologies, but although there are lots of cool things about them, I never could get them fully working. There are hints that the far realms are infinitely big, but its also not clear that anything in the far realms is actually real or whether reality has any meaning there.
There is no explicit 'great wheel' per se. Officially, the great wheel is one of the simplified illustrations shown to new students of the arcane, and it's even less accurate than the Bohr model of the atom. The outer dominions both partially preexisted and were partially created by the gods after the God's War. However, whether out of laziness or otherwise, their is just about a one to one relationship between those dominions and the canonical D&D dominions.
As to the inhabitants of the outer planes, there is a very different structure. For the most part, there is no parallel hierarchy of the gods and outer-planer natives. I've never really decided what if any canonical AD&D fiend lords are real, but all the celestials and infernals are definitely servitors of the gods and created in some way or the other by them. All the Fiend lords are vassels of dieties, just as all the solars and similarly high ranking celestials are vassels of their deities. The Modrons and Slaad are however unique. No one really knows where they came from. Yorlg and possibly Ssendam and some of the other Slaad Lords do know where the Slaad come from, but they aren't talking about it. Primus knows where the Modrons come from, but the only thing he's ever said on the matter is that they were created by necessity and its not clear if he means a being or simply because the universe couldn't exist without them. Personally, I admit I'm not fully clear on that myself, as I've never run a campaign where they were central to it. I do have a Secundus - the Prelate of Submission - as a bit player in the current campaign, but I'm not entirely sure what I'm going to do with him.
I've never really fully fleshed out the pantheon (it's supposedly got 1000 deities), and I've paid especially small attention to the LN's because you hardly ever get a player character that is LN and 'authority' is a tiresome trope as a foe, especially in D&D where players are all the time expecting all NPC's in authority to be incompetent or belligerent or both, so I've never really figured out the relationship between Primus and the deities. The Slaad everyone just stays out of the way off.
As for the why the humans are still around, the good gods knew that punishing the innocent was neither just nor kind. The neutral gods were afraid of upsetting the balance. The evil gods treated the whole affair as the discovery of a new shiny toy to use. The goblins advocated for it, but by this time it was clear Maglubiyet had an angle and there were serious questions whether the goblins were still a free people. The elves basically wanted them dead, but their chief Corwin vetoed them - the other elven pantheon deities largely believe that this is because his daughter Amaya (who is wed to Lado, who is Uman's son) pleaded for him. The dwarves largely agreed that the world would be better without them, and suggested that perhaps the humans should start over from scratch with a better thought out model (one that was more dwarfish). The fairies just shrugged and went back to thinking whatever it is that fairies think about, and Pitarian the God of Fools said that the should leave them alive in case they needed something to kill the gods with in the future.
