Hi, so I am a Geographer in real life, and I love to get really invested in game lore.

So my simple question: Why did the climate of Coerthas change so significantly between 1.0 and 2.0? Did Bahamut's magic just magically lower the temperature or is there something else at work? I know Shiva was in the area eventually, but I haven't found many NPCs that discuss this stuff.

Anyone got any ideas?
