I really like to speculate about one character
It’s about the fairy you meet at the beginning.
Bravely Default Ending Spoilies ahead!!!!! (also large textwall)
It was revealed at the very end that she was not Airy. It was Airy’s sister that recruited you/the Celestial to helping stop Ouroborus from getting into the Celestial Realm and eating everyone.
Take note on her wings in the intro/ending. Then look at Airy’s wings before shit goes down (namely when the number on her wings is the number one.)
I actually took notice of this when I saw a post with some concept art of Airy.
Airy’s sister’s wings have -1 as the pattern.
This could symbolize how she managed to get into the celestial realm in the first place. But how did she manage to get that far?
these are, of course, just headcanons…but considering that she’s Airy’s sister, they had to both be created by Ouroborus. she either had this in the first place and she was supposed to be like a spy and observe the Celestial realm or something but managed to change her mind and try to stop him…Or maybe the sister is the less favored/weaker one but she actually has powers they didn’t expect and stopped them out of spite
or maybe it’s just the whole good/bad twin duality thing idek
but moving on from that-
If you have the AR cards from the special edition (or got the images on the internet or something), you have that one card that’s like yellow with “Airy”(actually her sister, note the -1 wing pattern) on some windy cyclone bg or something, which has a tiny AR movie on it which basically sums up as Airy’s sister coming to you and asking for help because Luxendarc is in danger.
It’s implied that she’s done this multiple times and you were the last one she asks.
Which begs the question: What happened to the last ones she tried to recruit?
Another headcanon here, but the numerous times that Airy slaughtered the heroes in previous worlds? That might be because the Celestial that was guiding them either did something wrong or was too weak to stop her. MAybe Airy’s sister needed someone who either was or wasn’t genre savvy enough to break the crystals once any slight suspicion of Airy comes around. So that they’ll be able to gather enough strength to face mr. big bad universe eater head-on. Or some other reason. I might just be pulling things out of my ass here
so..uhh…that’s my long-winded theory about stuff. I might be wrong, maybe you guys have some better input. But there you have it.
