Not like just because we have defeated three Ascians means they're all gone. We have still 8-10 left, if not more. Who said they're not able to replace the ones that are dead, ... with newer ones?
Like I said before, just because we have the Echo and the Blessing.. makes us even strong to scratch them. Yet... we still need the Tools to completely erase them from existence or else they will just keep running away and cause more Chaos.
Ascians are the "Real" Bad Villains in this Game, heck one knows how long they exist? They basically caused every seven Calamities and living that long would cause me to become a Psychopath aswell like Lahabrea.
They're "Trolling" us in fact, like I said before, in ARR they explained the Beast Tribes to summon even stronger Primals (Primals tend to suck up the Aether from Hydaelyn herself which weakens her), so we slay them and they're getting more afraid and attempt to re-summon again.
Weaker Hydaelyn = She gets too weak = Zodiark Time it is
The entire "Lore" behind FFXIV can't be explained in some Sentences. Heck, 2.5 even explains us the structures of the Ascians, how they're able to live, what happens if their Host Body dies, what happens to their Soul?
