Conjecture Question..Any evidence to support/reject this theory concerning Echo?

[Lady]

This theory doesn't hold much water, and there are a couple of simple reasons for it without even needing to dig heavily into 1.0 lore.

1) Yoshi has confirmed himself that Louis tucked us away in a pocket dimension for 5 years in order to avoid the calamity. You would have to believe that Yoshi himself would lie about this, and you know how he is about lying and following through with promises.

I apologize, in no way did I intend to call Yoshi-P a liar...

2) ... Oh, sorry, that whole thing was just the Echo so even though it all seemed to matter pretty much everything you did couldn't change the past anyways.

While, Im not looking to support my argument, I find it interesting to note that no matter what we did, we couldn't stop dalamud from decending....
