To nitpick, Ishgard was never it's own nation. Limsa Lominsa, Ul'dah, Gridania and Ishgard are all different city-states which make up the collective-group (?) (don't know exact term) called Eorzea. Ishgard, however, withdrew from the Eorzean Alliance early on, hence why we only have the three starting cities.

You see Ul'dah's chocobo in the very foreground as the chocobos keep plowing ahead.

BUT LIMSA PRIDE. /gcsalute
