I doubt that is Azdaja in the photo tbh. Azdaja was described to have birdlike features and more of a beaked snout, more feathered appearance similar to Hraesvelgr, and talin like claws. The dragon in this photo is anything but that, and also has both of its eyes. This dragon resembles more Tiamat. And as we learned from completing Eureka Orthos floor 30, Tiamat is one of the only living beings with mastery over the void/dark aether.

Tiamat is probably our way back to the 13th and will be assisting us in the trial against Golbez to rescue Azdaja is what my opinion is.
