How do you think Eden will proceed?

[Kesey]

Maybe this is a bit of a stretch, but if Eden could be sent to the 13th could it be used to save that shard much like The Empty?

But for sure, we fight the voice that Gaia hears (I think she calls it a faerie?) who is either Ultimecia or something very Ultimecia like. We save The First's Empty and its going to recover the planet as a whole.

Note sure this plot line will really give hints beyond Gaia and Ryne will live happily ever after looking after The First, but I highly suspect that Ryne will be Hydaelyn's vehicle of communication in 6.0 because I doubt we have the show down with Zodiark without talking with Hydaelyn first.
