Oftentimes upon their way they had to pass through forests, caverns, and rock-shadowed paths, where it was so dark that at first the king feared he should lose his Shadows altogether. But as soon as they entered such places, the diamond in his sceptre began to shine and glow, and flash, sending out streams of light of all the colours that painter's soul could dream of; in which light the Shadows grew livelier and stronger than ever, speeding through the dark ways with an all but blinding swiftness. In the light of the diamond, too, some of their forms became more simple and human, while others seemed only to break out into a yet more untamable absurdity. Once, as they passed through a cave, the king actually saw some of their eyes--strange shadow-eyes; he had never seen any of their eyes before. But at the same moment when he saw their eyes, he knew their faces too, for they turned them full upon him for an instant; and the other Shadows, catching sight of these, shrank and shivered, and nearly vanished. Lovely faces they were; but the king was very thoughtful after he saw them, and continued rather troubled all the rest of the journey. He could not account for those faces being there, and the faces of Shadows, too, with living eyes. But he soon found that amongst the Shgadows a man must learn never to be surprised at anything; for if he does not, he will soon grow quite stupid, in consequence of the endless recurrence of surprises. At last they climbed up the bed of a little stream, and then, passing through a narrow rocky defile, came out suddenly upon the side of a mountain, overlooking a blue frozen lake in the very heart of mighty hills. Overhead, the _aurora borealis_ was shivering and flashing like a battle of ten thousand spears. Underneath, its beams passed faintly over the blue ice and the sides of the snow-clad mountains, whose tops shot up like huge icicles all about, with here and there a star sparkling on the very tip of one. But as the northern lights in the sky above, so wavered and quivered, and shot hither and thither, the Shadows on the surface of the lake below; now gathering in groups, and now shivering asunder; now covering the whole surface of the lake, and anon condensed into one dark knot in the centre. Every here and there on the white mountains might be seen two or three shooting away towards the tops, to vanish beyond them, so that their number was gradually, though not visibly, diminishing. "Please your majesty," said the Shadows, "this is our church--the Church of the Shadows."
