maybe with a way people think the darker au ra the xaela are going to be demonic while the rein are more draconic, it might be a good assumption (for now) to say that the xaela have more biblical/ demonological names such as lucifer.

then again we know hardly anything of the xaela we only know one Raen and we know theres are japanese like so on the 27th (when i think benchmark will come out) we will see but i do hope they post the naming conventions soon, i have been sat on a name for my raen au ra for a while and i want to be lore friendly D:
