There's something I've been wondering about: I never played 1.0, but the impression I get of Coerthas was that it was much more arable before the calamity, particularly in Western Coerthas with the abandoned hamlets. Then once the calamity hit, Coerthas quickly becomes a frozen wasteland. Without any farmland left, what exactly do the people of Ishgard eat? We get a few quests showing that those in the Brune are struggling sure, but with the level of devastation presented, one would think that even the High Houses would be hit by the sudden loss of agricultural production.
