"What is that thing that seized me, that enigmatic Raider through time? God alone knows, if even He is aware of its existence. But I know that it swept down on me through time and seized me, that it flashed with me through those three years in almost as few minutes. And I know that it has marked me for its victim and will come for me again, maybe in pure revenge for that shot of mine that released me. "Where is there refuge from a thing like that, that can speed through time and space at will? Twice I have escaped it, but I fear I can not escape it again, when it comes to claim me. And sooner or later, it will come!" _CHAPTER 3_ THE RAIDER A silence hung over the room when Cannell ceased to speak. I drew a long breath and turned to Lantin, my brain awhirl, but already he was calmly questioning the archeologist. "This thing you call the Raider," he began; "I don't understand your description very well, Cannell. Do you mean that it was just misty gas or vapor, able to change into solid form at will, and change back? And, withal, a living, intelligent thing?" "I mean just that," Cannell told him. "The thing is undoubtedly a sentient, living being of extraordinary intelligence and powers, able to assume either a solid or gaseous form. The phenomenon of the three shining orbs, changing from green to purple and back, is connected with that change in form, I assume. And at the same time I believe that triangle of the three lights to be the center of the thing's consciousness and intelligence, its brain and sense organs. "Such a thing is not impossible, Lantin," he went on. "You and I, intelligent, living creatures, are composed of solid and liquid elements, but there is no real reason why life and intelligence could not be present in an entirely gaseous creature. And as I believe, this creature only assumes the gaseous form when it is traveling through time. The winds that accompany its passage through time are undoubtedly caused by the fact that as it flashes on into a different time, it leaves in the atmosphere a sudden vacuum, and the surrounding atmosphere rushing in to fill this vacuum causes the gusts of wind." "But where could the thing come from?" Lantin objected. "Where was it taking you?" Cannell's face darkened. "I believe that it comes from the far future," he said slowly. "Who can say what manner of creatures will inhabit earth a million years from now? And it may be that this thing, a being of some future age, has discovered a way to travel through time and now sweeps back at will, snatching up luckless humans in every age. The purpose of these raids, who can say? Maybe for victims or slaves or food even. It is all a mystery, even to myself. One thing alone is clear to me, that the thing does come from some future time, since it was speeding back into the future with me when I escaped it."
