One of the biggest differences between Eorzea and the real world is that Eorzeans are not living in a digital age, where news and information from across the realm are readily available to all. There is plenty about each region of Eorzea that we don't know--and can't know--because our characters don't possess the shared and stored knowledge of every person who lives in every corner of it. Even in a big city, a few rumors here and there will only scratch the surface of everything there would be to know and see if the citizens had iPhones.
What I'm saying is, from your perspective the Au Ra just "appeared". From your perspective Rogues just "appeared" as well.
I heard a rumor that a Mammol Ja regularly visits a butcher's stall in West Hawker's Alley to buy enough raw blood sausage to feed a small army. I also heard the Mammol Ja tribes have been becoming increasingly interested in the Arcanist's Guild for reasons unknown. And hey, I heard they hired some dancers at the Gold Saucer who have horns instead of ears and hail from the Far East.
Can you believe that?
