After all we've been through, i still wonder...

[Adelle]

Where has Ishgard been? airships traveling through their lands and the leader of the eorzean invasion force almost right at their footstep, are they so paranoid of the dragons return that they do nothing?

[Airget]

We'll most likely know in a few weeks. This is probably why it's the only region with no lore on it yet since they are still keeping it a secret.

They're on their way to help, but they're only halfway across that bridge.

[Skies]

If you notice the opening cutscene... You'll realize that what stopped the initial garlean invasion were the dragons from Dravania.

And if you played the Dragoon quest line, you know that those sleeping beasts are on the verge of awakening again, let by Nidhogg, to once again attempt to lay waste to Ishgard...

They pretty much got a force equal in strength to the Garleans about to essentially declare all-out war on them. I'm sure they've got their plates full.
