(Yes its from "Avatar" but I thought it would be cool.)
Here the mountains are flouting in the ski. The rivers fall off the edge and evaporate. The ground below is infested with trees and such. The inhabitants included giant monster dog like things the size of elephants. Also giant periodical's fly around that will take a bite out of crime, and your arm. Because of the magnetic field that holds the mountains up mess with your instruments so you auto pilot it and the clouds make it so you cant see where the heck you are going up there. This place make Red unable to use lock-on weapons of sort. "Ain't that a bi@tch."
