If au ra can breed with hyur, then they’re not reptiles or close to reptiles. In our world at least, mammals close to reptiles still have cloaca and lay eggs. They can’t be related to the first brood either since dragons didn’t come to Hydaelyn until after the worlds split, yet au ra show up on the First.

They just happen to be their own (weird) thing.
