You're a Xaela, right?
I think this is most of what you need to know to get started:
1. Flavour from the character creation screen.
Tl;dr: "free-spirited vagrant" is the Xaelan archetype, so you're in luck!
2. Naming conventions.
Tl;dr: you know Mongolian, right(?) xD
3. Geographical origins.
Tl;dr: your character probably isn't from Eorzea originally.
I think that's everything that's... important. Everything else is fluff and flavour that you can have excuses for your character not to know either. xD
