3.4 speculation

[Nestama]

If we're travelling to Ala Mhigo as many of us expect then yes, Castrum Oriens would be the most likely route for us to take. There is another route via Coerthas, however, so that still remains a possibility.

Looking at both the 1.0 map and Eorzea map, I doubt Coerthas Eastern Highlands will be a potential location to Ala Mhigo (it's more to the west) and Xelphatol. Too west.

Where did Coerthas Central Lowlands go?

I have a feeling the northern most area of Gridania will lead us to Xelphatol (or another Gridania zone leading to Xelphatol).
