[Spoilers] The Patch 4.2 Discussion and Speculation Thread!

[Belhi]

Just a thought but could Eureka be tied to the loss of the Isle of Val? I have been trying to place those screenshots of Eureka and beyond the Aetheryte being Eorzean I can't place the architecture. However we do have that dialog when we see Krile that goes along the lines of:

"While I dare not give myself wholly to hope, I will not deny that I have prayed for such a miracle ever since that fateful day."

Plus they did say we would find out more about the Isle of Val in 4.X.

Edit: Apparently the dialog for the MSQ is fairly different depending on the language. Yotsuyu however seems to generally be rather childlike. Maybe she has regressed to what she was like before she was married off.
