FFXIV is actually very flexible in terms of background and history; Since Eorzea's been populated for a couple hundred years by all of the playable characters (barring Au Ra) there's no reason that you have to be from a specific place just because you're playing a race. Ala Mhigo in particular saw races of all varieties inside of her borders before she fell 20~ years ago, so being from the back marshes or hillbilly woods isn't that far fetched.
