Needlestack Mountains

The mountain range forming the eastern border of Archaea, the Needlestack Mountains are completely impassable by mundane means. Any who try to scale these impossibly high mounts find themselves sickening and suffocating long before they reach the top. Myths about the mountains abound, however. It is claimed by some that a great archway lies hidden deep in a mountain coomb, which once led to the lands of the East before it was forever shut. If the elves have found such a thing, they have not reported it to outside scholars.
