This is focused around a high mountain valley with a very tall mountain in the center (+8000m). The world is very old; empires have risen and fallen, and the world is in one of its dark ages. This map is an old map from an earlier age, written at the fall of the last empire. Thus, the lettering on the original map is different from english (though if you solve the simple substitution cipher, you can read it):

But I have also changed it into english for ease of reading:
