GOT IT! I'm holding up my PSP (with CT loaded, on the 1000 AD zoomed-out world map) next to the monitor, and I can see a match. (I've got it rotated... The top-left corner of the PSP is pointed straight down, so I'm holding it diagonally.)
That continent in the center is Choras. The island in the bottom-left is the Sun Keep. Bottom-center is Medina, bottom-right is Zenan. Guardia is completely off the map, unless they wrapped it around to the top-left, which is what it looks like they did. Just up and right of the planet's center is a small island that I can't account for, although it does look like a string of islands. This is most likely El Nido. Finally, on the top right is a larger landmass, not quite a continent but too big to be an island or part of El Nido...I can't account for that either.
However, the ones I DID account for...the landshapes match. If I'm correct (and I'll show you a picture of how I'm seeing this later tonight when I get off work), then El Nido is off the southern tip of Choras. Absolutely the most remote area in the world. For Porre to have strong militaristic influence here pretty much seals it that they've conquered the world.
