I don't know too much about the world beyond what's mentioned in the show, but from the sounds of where Sam his heading to become a maester, I'd probably be there. Not a maester, some low-level scribe position.

I'm from Detroit so I'd be ironborn, since the Greyjoys are the poorest house. Sounds like a tough place to be transgender. I would sail around until I found the necessary magic to change my body, then make an honest living delivering things to and fro. 

Given your current status (education, economic, social, profession) what would you be in Game of Thrones?
