What do you think, Southperry, on this?

Well, this is what I think:

here's my notes on the map.

 Spoiler

The ??? area, I'm not sure. Check out the trees I circled. The one on the left is the Jungle tree, while the ones on the right are of a more deciduous nature. This would lead me to believe it's a more forest like area (similar to what you see in Omega) but there's nothing that would really point to this area's existence thus far. Krakia is pretty obvious; I think most of us expect that dome to be it. Prose specifically said Crimsonwood is to the left, and it's in phantom forest, which is also to the left, so I believe it will be in the northern area by the mansion. Seems simple enough. As for continuing the Jungle's path through the mountains, this will lead to some as-of-yet unseen region which may sport some of the areas already predicted. The area you guys are calling "Foxwit's den" is simply one of those pyramid-cubes that is floating over foxwit's head. Go to NLC and check it out for yourself.
