There isn't. There's a mention about other continental masses and the mention that the Garleans invaded and fought the Primals of those lands. But nothing specific about culture, cities or races that you can find in them. So it's not a particularly good idea to create a character that comes from any of them, since there's nothing to work on and, if you made things up, you run a great risk of needing to retcon it at a later date (if the official lore ever decides to say anything that contradicts your backstory, basically).
