Hello, My Name is Human

[Gemina]

Au Ra are dragon-kin so they're reptiles not mammals, they're already a different species.

Well, according to their lore, their progeny to dragons is disputed by scholars and they are described as "Hyur-like". I am also going by that they are not referred to as a different species anywhere in the game to my knowledge. Just another playable race. Each race could make a case for being a different species to be honest. Even Hyurs are technically humanoid.
