The Road to 5.0

[KageTokage]

They haven't really touched on it since 2.x, but the Ascians (It might've been Elidibus, specifically) mentioned how they intend for us serve as a key of some sort, but we weren't yet ready for that purpose and needed to be stronger. I'd assume 5.x is where they're finally going to make their move and have us unwittingly play into their hands.

The thing I'm curious about is just how bad the fallout from it is going to be, since that song implies it could practically invalidate the good we've accomplished thus far.

I feel like we're going to have face Zodiark at some point before the story can end, but with multiple shards still not having been assimilated back into the source, the Ascians would need a way to speed things up either by causing a calamity so bad that the energy of multiple shards is needed to recover from it or they have a plan to break Zodiark's seal without need of a complete rejoining...somehow.
