As something of a young'un on FEI, just a few comments.
People seem to have a lot of confident in Arcachon's ability to punch above its weight. Their income is barely more than half that of Cathay, PoZ, or Kindara. And they're about to go toe to toe with Arcaea, which is substantially bigger again.
I'm suprised Zonasa is rated so lowly. Humilating defeats aside, they're still second in terms of nobles and more-or-less equal second with Cathay by income. Aenilla is a nice meatshield against Arcaea and they've got good natural defences against Cathay. Only their allies in Kindara could actually hurt them without a lot of work.
Also, why does C'thonia even still exist. One city and two rural regions is just... painful.
