If you're still taking in concepts, I had a notion for a paladin from Osirion affiliated with the faction from such, here out of the belief of that, whatever may or may not being going on with Aroden, his renewed civilization needs to be here, as the city would otherwise be at the mercy of infernalists, decadent empires, plutocrats and the like. That it would generally be bad for his own people otherwise if the city fell into the hands of any of those as far as the strength it would give them, that they could then turn on others. So an idealist basically, who legitimately believes the reborn strength of his homeland can be a force for stability and good across the planet, though an idealist not without an understanding of wider political nuance. Otherwise a believer in the need to boot the other groups out of the city, to show the benefits of being under the aegis of his homeland, to make sure the people in districts under their control are being treated well and having their hearts and minds won over, as the expression goes. Possibly reach out to such local insurgencies as may be forming. Certainly aware and no doubt seeing first hand a lot of horrible crap going on in the city, but only having that strengthen his resolve to maintain a honourable core to himself and show others that can be done.
So of the "idealists/not" conflict in Osirion, a representative of that first group. I'll put together a full writeup in a bit, just wanted to float the initial idea first.
