This room, table, bench, had all been designed with a set purpose. And that purpose—Travis' fingers rested on the box of tapes he could not yet bring himself to open—that purpose was to use the reader, he would swear to that. Tapes so left must have had a great importance for those who left them. It was as if the whole valley was a trap to channel a stranger into this underground chamber.
Travis snapped open the box, fed the first disk into the reader, and applied his eyes to the vision tube at its apex.
The rippling walls looked just the same when he looked up once more, but the cramp in his muscles told Travis that time had passed—perhaps hours instead of minutes—since he had taken out the first disk. He cupped his hands over his eyes and tried to think clearly. There had been sheets of meaningless symbol writing, but also there had been many clear, three-dimensional pictures, accompanied by a singsong commentary in an alien tongue, seemingly voiced out of thin air. He had been stuffed with ragged bits and patches of information, to be connected only by guesses, and some wild guesses, too. But this much he did know—these towers had been built by the bald spacemen, and they were highly important to that vanished stellar civilization. The information in this room, as disjointed as it had been for him, led to a treasure trove on Topaz greater than he had dreamed.
Travis swayed on the bench. To know so much and yet so little! If Ashe were only here, or some other of the project technicians! A treasure such as Pandora's box had been, peril for one who opened it and did not understand. The Apache studied the three walls of blue-purple-green in turn and with new attention. There were ways through those walls; he was fairly sure he could unlock at least one of them. But not now—certainly not now!
And there was another thing he knew: The Reds must not find this. Such a discovery on their part would not only mean the end of his own people on Topaz, but the end of Terra as well. This could be a new and alien Black Death spread to destroy whole nations at a time!
If he could—much as his archaeologist's training would argue against it—he would blot out this whole valley above and below ground. But while the Reds might possess a means of such destruction, the Apaches did not. No, he and his people must prevent its discovery by the enemy by doing what he had seen as necessary from the first—wiping out the Red leaders! And that must be done before they chanced upon the towers!
Travis arose stiffly. His eyes ached, his head felt stuffed with pictures, hints, speculations. He wanted to get out, back into the open air where perhaps the clean winds of the heights would blow some of this frightening half knowledge from his benumbed mind. He lurched down the corridor, puzzled now by the problem of getting back to the window level.
Here, before him, was the pillar. Without hope, but still obeying some buried instinct, Travis again set his hands to its surface. There was a tug at his cramped arms; once more his body was sucked to the pillar. This time he was rising!
He held his breath past the first level and then relaxed. The principle of this weird form of transportation was entirely beyond his understanding, but as long as it worked in reverse he didn't care to find out. He reached the windowed chamber, but the sunlight had left it; instead, the clean cut of moon sweep lay on the dusty floor. He must have been hours in that underground place.
Travis pulled away from the embrace of the pillar. The bar of his wooden lance was still across the window and he ran for it. To catch the scouting party at the pass he must hurry. The report they would make to the clan now had to be changed radically in the face of his new discoveries. The Apaches dared not retreat southward and withdraw from the fight, leaving the Reds to use what treasure lay here.
