The Rejoining (Spoilers for EVERYTHING up to 2.55, welcome to Lore)

I'm wondering if that's truly the case if Elidibris thinks the WoL would side with him if they were stronger with the Echo.

I think it's more a case of some of the 'bad' stuff the Ascians have been doing might not seem so bad if we understood why they were doing it. At least that's how I interpreted Elidibus on that one. This was what original sparked the theories about Hydaelyn actually deceiving us. Either way I think it's safe to say there's a lot we don't yet know about the nature of the universe and it's entirely possible, given a big-picture view via the Echo, that we might see the truth of Elidibus' words.

Concerning Elidibus, I interpret his words and actions as being "true neutral" which is Not unlike Zodiark's clan primer description in FF12 and Revenant Wings: that of an unbiased judge who measures your worth. Zodiark is also opposite of Ultima in Ivalice lore, who like her angelic partner Zalera, defied the gods while Zodiark was just sealed away out of caution for being too strong. I can't say the same for fellow "abnormal" Ascian lahabrea, because Mateus was a pretty nasty dude.

And since the Ascians all appear to have different goals, I wonder about two things: which ones are responsible for what Umbral Era, and if SE will take the route that has them emulating their Espers' histories in FF14. For example, Samyaza/Shemhazai is the Whisperer, known for being the one that influenced Ultima and the others to rebel.
