The Wayfarer's Inn

What? ! ? Glantri destroyed the City built by Magic? That's next to impossible! Sundsvaal was that city? I had dreams about that city when I was a kid! It was inpsiring! Why would Glantri do that? What did the Gods did to prevent it?

My main reason for wanting Alphatia back is not to oppose Thyatis but rather to have that city back!

Important Clarification: I have: Rules Cyclopedia, Poor wizard's Almanac II, Dawn of Emperors Gaz.
So I can't really appreciate the battle-readiness of the Alphatian fleet in something that I have never heard of, much less own.

However, from the Almanac the Alphatian flying navy seems very good, but nothing too awe-inspiring.

And the question remains: Why would Thyatis consider to attack well defended independants halfway around the world, still loyal to Alphatia (that is Alatian isles). Yeah, Thyatis may decide to get a couple of these flying ships, but they could buy them instead of starting a war with something so far away.
I would really like to know why you think these flying ships were so important as I don't think that the benefit from having them would outweight the heavy losses and long war that Thyatis would get into in order to get Alatian isles.
As far as I have seen in the Almanac they are just that: Ships that fly rather quickly with 3rd-5th level crewmembers.

Thanks. Anyway... in your campaign what happened? Alphatia destroyed everything in their way to Glantri, leaving the Known worlds a ruin and defeating its only major antagonist? Or they just hardened the life for Thyatians, while losing much power themselves leading to a very unstable situation, that both empires would need a generation in order to recover and start bickering over the Isle of Dawn again?
