A howl of triumph went up from the hordes on the stair. Away down and around the spiraling stairway it went, down all their packed masses, down into the shaft to the pit itself, all taking up and passing on that savage, exultant shout.
For we had lost. Kethra had lost. The Raider had somehow eluded him, in time, and had come back to destroy us and to loose his hordes on the flying-platforms, to send them down to Kom in a rain of death, while Kethra vainly searched time for the Raider. We had lost.
Slowly, slowly, the Raider came down toward us, while the hordes below us watched with delighted expectancy. Spinning, twisting, it sank down until it hung a scant twenty feet above us, and we waited, helpless, for the destroying flashes from the central orbs.
Suddenly D'Alord stepped forward, and uttering a yell of defiance, he picked a sword from the floor, whirled it around his head and sent it hurtling spear-wise up toward the Raider.
It fell back, missed by yards. And now the gray, shapeless mass of the Raider spun and laced with inconceivable rapidity, while down upon us darted flash on flash of purple, destroying fire, from the central orbs.
The flashes fell short! Between us and the Raider was hanging a veil of transparent black, a tenuous black net that was suspended in midair above us, and against which the purple flashes splashed and stopped. I turned swiftly, and a little behind and above me was hovering the air-boat of Kethra. It moved toward us, and we stepped on it. And in that same instant, there appeared in the air all around us, above and around the temple and the Raider, score on score of the air-boats, crowded with the men of Kom.
From them darted a hundred black nets like the one that hung before us. The black veils closed upon the Raider, contracted, and while he spun and changed and twisted with mad speed, the veils contracted still until they were a black ball five feet across, in which he was prisoned. Then, from Kethra's air-boat and from all around us, there darted flash on flash of orange flame, which struck the black ball, burned fiercely for a moment, and then vanished. In the air there drifted only a shining mist, and then that too was swept away!
Now, from all the hovering air-boats came the thrumming of the sound-rays, directed at the temple and the city, from all the scores of cars that hung above that city. The ground beneath pitched, heaved up torturedly, and then the city collapsed, sank down with a thundering, ear-splitting roar into the great pit that lay beneath, the earth over the cavern being shattered by the disintegrating vibrations of the sound-rays.
All the city, with the great temple below us, crashed down, and vanished in a mighty cloud of dust. The dust hung, cleared, disappeared. And beneath lay nothing but a great depression in the earth, a vast, raw bowl in the earth's surface, with here and there a white fragment showing in the brown earth. Under that huge sunken bowl, I well knew, lay the city of the cylinders, with its Kanlars and soulless slaves, and under it, too, lay the city of the pit, and the people of the pit, the thousands of fierce warriors who had pressed us up the stair so savagely, seeking to carry destruction and death down to a peaceful city.
