A moment he hung below us, a thing of whirling mists, the three orbs of green glowing radiantly through the darkness. Then he had dropped down onto the battle, expanded, extended his own misty form until it held within it the score of air-boats in which were the survivors of the Kanlars' forces.
A second it continued thus, its vaporous form enveloping the remaining cars of the Kanlars, and then, out from the green, radiant triangle of orbs there burst flash on flash of green light, aimed at the surrounding cars of the Khluns. The cars touched by that green light vanished, simply disappeared from view, leaving a little cloud of radiant sparks which dimmed and vanished likewise.
There was a great shout from behind us, and down toward the Raider, from the car of Kethra, there dropped a thing like a black, enveloping net, queerly tenuous-seeming in the one glimpse of it I had. It was like a net of black force, dropping down on the Raider, but before it reached its objective, the Raider and the cars it held within it had abruptly vanished.
"The Raider!" cried Kethra. "He's gone on into time, with the surviving Kanlars! Follow, follow, follow!"
From the scores of air-boats below us came a savage yell, and there was a second's pause, a second's silence, and then our car was struck by a gale that nearly overturned it, and we hung alone in space. Kethra and his air-boats had followed the Raider on into time, with the time-wave apparatus we had showed them how to use. I knew, too, that at that moment half the air-boats were speeding into the past and half into the future, in search of the Raider, for that had been our plan in case we had need to pursue the Raider into time.
"Shut the car-door!" I cried to Lantin. "We'll follow, too."
"Wait!" he shouted, his head out of the circular door, peering away to the north.
The gray light of dawn was welling up in the east, and by it I saw, away to the north, a black speck that rushed down toward us. It raced on, and now I saw that it was a Khlun air-boat. It sped on toward us, and now I recognized it as the one we had dispatched to rescue our four friends from the pit.
The car sped on toward us, and I saw that on it were the pilot and his two aides, but not our friends. Even before the pilot shouted to us a premonition of disaster filled me.
