Beyond, scores had gathered, their occupants evidently discussing us in much excitement. The green dwarf waved us to the piles of cushions and then threw himself beside us. The vehicle started off smoothly, the now silent throng making way, and swept down the green roadway at a terrific pace and wholly without vibration, toward the seven-terraced tower. As we flew along I tried to discover the source of the power, but I could not--then. There was no sign of mechanism, but that the shell responded to some form of energy was certain--the driver grasping a small lever which seemed to control not only our speed, but our direction. We turned abruptly and swept up a runway through one of the gardens, and stopped softly before a pillared pavilion. I saw now that these were much larger than I had thought. The structure to which we had been carried covered, I estimated, fully an acre. Oblong, with its slender, vari-coloured columns spaced regularly, its walls were like the sliding screens of the Japanese--shoji. The green dwarf hurried us up a flight of broad steps flanked by great carved serpents, winged and scaled. He stamped twice upon mosaicked stones between two of the pillars, and a screen rolled aside, revealing an immense hall scattered about with low divans on which lolled a dozen or more of the dwarfish men, dressed identically as he. They sauntered up to us leisurely; the surprised interest in their faces tempered by the same inhumanly gay malice that seemed to be characteristic of all these people we had as yet seen. "The Afyo Maie awaits them, Rador," said one. The green dwarf nodded, beckoned us, and led the way through the great hall and into a smaller chamber whose far side was covered with the opacity I had noted from the aerie of the cliff. I examined the--blackness--with lively interest. It had neither substance nor texture; it was not matter--and yet it suggested solidity; an entire cessation, a complete absorption of light; an ebon veil at once immaterial and palpable. I stretched, involuntarily, my hand out toward it, and felt it quickly drawn back. "Do you seek your end so soon?" whispered Rador. "But I forget--you do not know," he added. "On your life touch not the blackness, ever. It--" He stopped, for abruptly in the density a portal appeared; swinging out of the shadow like a picture thrown by a lantern upon a screen. Through it was revealed a chamber filled with a soft rosy glow. Rising from cushioned couches, a woman and a man regarded us, half leaning over a long, low table of what seemed polished jet, laden with flowers and unfamiliar fruits. About the room--that part of it, at least, that I could see--were a few oddly shaped chairs of the same substance. On high, silvery tripods three immense globes stood, and it was from them that the rose glow emanated. At the side of the woman was a smaller globe whose roseate gleam was tempered by quivering waves of blue.
