I see. I was also wondering... could there possibly be some sort of war between Yislee and Ivalice, at least in the beginning before Grima re-awakens?

Now that depends on the PCs, as Grima is already there, just in hiding to regain his strength. The PCs will have plenty of enemies to fight other then themselves, but if the Ylissians start trying to strong arm the people of Ivalice, they may start a conflict.
