Well, there was already one instance of a npc in the game having come from Othard, although he was a Garlean soldier and his actual home city state was never revealed, other than that he was born in Othard (the highlander hyur engineer at Castrum Occidens during the cutscene that plays when you take an airship for the first time - the same scene where Nero executes the Ala Mhigan spy).

As well, the long-mentioned city-state of Radz-at-han apparently is located on Othard as well, a nation that has long traded with Eorzea, especially Ul'dah, despite being under Garlean control. In any event it's going to be interesting to see how the new story goes into filling in the blanks about the eastern most continent.
