Story for Aura?

[Korashy]

First it's "Au Ra," not "Aura" or "Au'ra."

Second, they're based on demons in terms of aesthetics. Supposedly. And there's nothing stating they have any connection to dragons (it's actually a disputed claim in-universe).

Third, if you do the DRK storyline you find out the Au Ra actually were persecuted by the Ishgardians for their superficial similarities to dragons.

I'll have to check it out, it just seems to be really conflicting with the close mindedness and instant heretic branding of Ishgardians. I mean in Coerthas they are telling you that besides the chocobo, all beasts and beastmen must be eradicated. Would have been nice if they resolved this via the main story. Then again, the player character is the Warrior of Light so I guess, we are an exception.
