Seriathus I imagine that we will also see some of the flags from the unpeople vote during the council and then the Eustrin final state. As well as probably our choice of high priestess to partner up with during the council.
I think that battle score will probably be important and will I assume calculate just how strong our forces will be to keep stability. Mixed with just how much other groups want the doom kings help from the acceptance variable.
What I am most curious about is what choice of where to send the ground forces is best. My speculating makes me think that Takkan will be extremely useful to help blunt Aram. Though if Aram cd is high enough and with the right flags on plus having Takkan both well developed and with several special orcs around they might be able to hold their own without the need for ground forces support.
Ardoheim still has a lot of military might and I can imagine if carinas men still live, the order of silence is around and in full force, Kalant and some of the other ardan suitors who arent total asses (Donovan) are well respect enough. Then I imagine that they can probably fend for themselves. Though I get the sense we might finally see Antorians karmic debt paid as well.
Zirantia I can imagine will be well off if you have the NUP running things and if you invest in their infrastructure project and getting rid of the fucklords corruption. Though with the divine claw still damaged as it is they might be lacking a lot of man power. I can see why they might be a good choice.
New Givini I can't tell where its at really, they don't really talk about it having a standing army. Just mages from the college and then veterans if you funded the monument. So they might end up needing the military might the most.
