It was supposed to be Acatharsis, not Acarthasis. But whatever you all like is fine.
Anyway, I vote for Iberia. Foodstamp, you might consider throwing in some inquisitors for priests, and possibly combine one with stealth. It would tie in with the secret police, priestly power, rise of the Pretender over the various groups I discussed earlier.

These are regular people, but due to nearly constant warfare are far more prepared for it than your average indep or militia, but by no means compare to the military power of the four groups.
