One thing I don't get is the idea that Ascians are tempered by Zodiark. Emet-Selch does mention during his reveal that Zodiark and Hydaelyn are primals that "we (Ascians) are tempered by Zodiark and we serve Him, simple as that" but the 5.X patches have revealed to us that the Echo was not a blessing of Hydaelyn or Zodiark but something the Ancients (and by extension the shards of the Ancients) possessed and that Hydaelyn has been sending out a constant signal to those who have it, not gifting it like we previously believed. So if the Echo was something that existed before the primals and that the Echo protects people from tempering, why is it said that the Ascians are tempered by Zodiark and the theory we could be tempered by Hydaelyn?
Are Ascians somehow tempered despite having the Echo? Emet-Selch is more about lies of omission so him straight up lying about being tempered seems out of character for him, but past this reveal Emet-Selch went on more about Amourot and the world that was than Zodiark, treating him more like a means to an end than anything. Even Lahabrea, in the patches leading up to Heavensward, seemed to have been more about himself than Zodiark, in the cutscene after Nabriales' death his relayed from Elidibus to Lahabrea, he states "The earth is fertile, and the seeds well sown. By my will, they shall reap salvation unlike any the world has know" and Elidibus quite pointedly responds "By His will." and Lahabrea just states "...by His will" before slinking off to Ishgard. This kind of talk doesn't sound like someone tempered. As for Elidibus, we now know his devotion to the plan was not from tempering but being a piece of the primal Zodiark Himself.
So are Ascians actually tempered or was the devotion (most) the Unsundered had to restoring their world akin to being tempered in that they could not be swayed from their course? Lesser Ascians like Fandaniel don't seem like they care at all and making a boxing match between what was thought to be the God he's devoted to and the sworn enemy that laid Him low a fun plan to enact.
