XI vs XIV Lore - similarities and differences

[Desudro]

The northern areas (North shore of Batallia, Sauromugue, and Qufim island) all have a blackened, crystallized look to them, as if some giant magical explosion occurred in the northern region. We don't see that anywhere in Eorzea. (I always wanted to know what caused this...)

I was under the impression that the blacked areas were caused by the Cataclysm that ended the reign of the Zilart that also froze Xarcabard and Beaucedine Glacier. That explosion also mutated the animals of the land to make the angry critters that want to tear our throats out most of the time...
