Just a few clarifications are in order Tiggy:

Actually Ishgard pulled out of the Alliance long ago - they don't have a Grand Company, and there would be no reason for them to form one given their continuing neutral attitudes to the Alliance. If anything this just probably alludes to the growing amount of adventurers all flocking to defend the realm due to the player's actions.

Ishgard is a theocracy (a country ruled by a church) and not a kingdom. Their head of state is an archbishop. But yes, given the recent revelations concerning the Holy See, it's entirely possible the player is going to be forced to take drastic action in order to avoid all out war. But I guess we'll see.
