So... Is Lahabrea REALLY dead-dead?

EDIT: And it might also be worth noting: if we can trust the Eden questline, it takes roughly 80-something years for a soul to be reincarnated, without factoring in aging. So realistically, even if, say, Pashtarot wants to uplift Nabriales again, they're gonna be waiting a while.

Gaia could have reincarnated multiple times in that period. Assuming that Ryne is a shard of Minfilia (as it is heavily implied), she reincarnated many times in that same span.
