Far ahead a point of light showed; grew steadily; we were within it⁠—and softly all movement ceased. How acute had been the strain of our journey I did not realize until I tried to stand⁠—and sank back, leg-muscles too shaky to bear my weight. The car rested in a slit in the centre of a smooth walled chamber perhaps twenty feet square. The wall facing us was pierced by a low doorway through which we could see a flight of steps leading downward.

The light streamed through a small opening, the base of which was twice a tall man’s height from the floor. A curving flight of broad, low steps led up to it. And now it came to my steadying brain that there was something puzzling, peculiar, strangely unfamiliar about this light. It was silvery, shaded faintly with a delicate blue and flushed lightly with a nacreous rose; but a rose that differed from that of the terraces of the Pool Chamber as the rose within the opal differs from that within the pearl. In it were tiny, gleaming points like the motes in a sunbeam, but sparkling white like the dust of diamonds, and with a quality of vibrant vitality; they were as though they were alive. The light cast no shadows!
