If you watch the trailer closely, you can see the stones of Gwyrr-Ann. Guess where the meteor debris was going? Ishgard. Ishgard is not spared in our fate.

With that said, we don't know what caused bahumut to stop killing everything and allowed the land to live for 5 years.
I've been wondering this since the first time I watched the trailer. Maybe Loiusoix went along with the "other" plan Cid talked about. Or a new potential ally or threat appears, Dravanians?
