I honestly don't know where this came from, or if the shapes of the continents are accurate, but I know its not official. It'll at the very least give you an idea of how much of Vana'diel we've never seen, and supposedly all of these landmasses are mentioned in the lore at some point.

I blame the limitations of the PS2 as always for we never getting to see this stuff...just think how much more amazing XI would've been if all this was available to play in and explore!

Vana'diel World Map?
