Sharlayan Being Attacked

[Malakhim]

The place where the battle in the CG intro is most definitely Mor Dhona, what with all the crystals/aetheryte scattered across the land, as well as the fact that in the middle of the lake is The Keeper(which is Bahamut) twisted around the airship that he took down in the battle(which took place from 10-15 years prior). The land in Mor Dhona is currently ruined due to the final "breath" of Bahamut, from which the physical manifestations of the other primals were brought forth.

The only city attacked by the Garlean Empire that we know of thus far is Ala Mhigo, which was the strongest of the Eorzean city-states. For reasons unknown(most likely due to their fleet's defeat at the hands of the dragons), the Garleans halted their assault after securing Silvertear Falls, which is apparently a valuable crystal vein, and have been doing nothing but spying on and spreading propaganda throughout Eorzea with their airships that you see flying around every so often.

Sharlayan is on the far west side of Adlenard near Dravania, the Farreach, and Abalathia's Spine. Chances are that there may have been conflict between them and the dragons, however the way Y'Shtola speaks about it in the Limsa plotline, it seems like there was more to the destruction of Sharlayan. As far as we know, the Garleans haven't made it that far yet.


Anyway there's a whole thread on all this stuff, so look it up if you want more plot clarification.
