Krakia?

The speculated area on the map, the name is called Jungle Valley, the side on the right where it branches. On top of that, though, the map adjacent to that, where the "pyramid" thing is, is at the same level as the Jungle Valley.

Only problem is, it makes more sense for Jungle Valley to lead to a new area than the other, unless they wanna pull the "portal in the middle of nowhere" stuff.
