Come to think of it, we've only seen Zodiark/the Ascian's perspective in all of this. Perhaps Endwalker is the Star's/Hyd's perspective, and we find out there's a loophole we can exploit.

Something like being able to undo the sundering of the land (after all, Hyd is the one that caused it) without killing the people living on the shards.

We could potentially end up in a (almost) restored world, Ryne and Gaia could join the Scions, and the logo would actually be a picture of the Star, rather than the moon-- just with a gaping hole where the Void resides.
