Then dim and misty in the darkling north before him he glimpsed a terrible thing. He had thought it for some moments a range of black mountains, but now he saw it was something more. The phosphorescence of the brooding clouds shewed it plainly, and even silhouetted parts of it as vapours glowed behind. How distant it was he could not tell, but it must have been very far. It was thousands of feet high, stretching in a great concave arc from the grey impassable peaks to the unimagined westward spaces, and had once indeed been a ridge of mighty onyx hills. But now these hills were hills no more, for some hand greater than man's had touched them. Silent they squatted there atop the world like wolves or ghouls, crowned with clouds and mists and guarding the secrets of the north forever. All in a great half circle they squatted, those dog-like mountains carven into monstrous watching statues, and their right hands were raised in menace against mankind.
