know.
.We returned to the cat door. There I lingered a moment, studying the mask symbol. Three men, one woman —who had they been? Rulers; priests and a priestess; scientists of another time and place? Why had they been left here? Was this a depository like our medical freezers, or a politically motivated safekeep where rulers had chosen to wait out some revolution they had good reason to fear? Or—
It seemed to me that the gem eyes of the cat held a malicious glitter, mirroring superior amusement. As if someone knew exactly the extent of my ignorance and dismissed me from serious consideration because of it. A spark of anger flared deep inside me. Yet I did not underrate what lay beyond that door and could be only waiting for a chance to assume power.
'Now where?' Borton glanced about as if he expected some guide sign to flare into life.
'Our other men,' Lidj answered that crisply. 'They have them imprisoned somewhere—'
I thought that 'somewhere' within these burrows was no guide at all. And it would seem Foss's thoughts marched with mine, for he asked:
'You have no idea where?'
It was Harkon who answered. 'Not where they are. Where
'You mean you can trace those?' Thanel demanded.
'Yes. Though whether mere confrontation will bring about another exchange—'
'How do you know?' The medic pursued the first part of his answer.
'I can't tell you. Frankly, I don't know. But I do know that whoever is walking about as Harkon right now is in that direction.' There was no hesitation as he pointed to the right wall of the passage.
Only, not being able to ooze through solid rock, I did not see how that knowledge was going to benefit us. We had found no other passage during our way in (I was still deeply puzzled about the difference between my first venture into the maze and this one).
Harkon still faced that blank wall, a frown on his face. He stared so intently at the smoothed stone that one might well think he saw a pattern there—one invisible to us.
After a moment he shook his head. 'Not quite here —farther on,' he muttered. Nor did he enlarge on that, but started along close to the wall, now and then sweeping his finger tips across it, as if by touch he might locate what he could not find by sight. He was so intent upon that search that his concentration drew us along, though I did not expect any results from his quest. Then he halted, brought the palm of his hand against the stone in a hard slap.
'Right behind here—if we can break through.'
'Stand aside.' Whether Borton accepted him as a guide or not, the commander seemed willing to put it to the test. He aimed his weapon at the wall where Harkon had indicated, and fired.
The force of that weapon was awesome, more so perhaps because we were in such a confined space.
One moment there had been the solid rock of this planet's bone; the next—a dark hole. Before we could stop him, Harkon was into that.
We had indeed broken through into another corridor. This one was washed in gray light. Harkon did not hesitate, but moved along with such swift strides that we had to hurry to catch up.
That passage was short, for we soon came out on a gallery running along near the top of another pyramid- shaped chamber. This one was triple the size of the others I had seen. From our perch we looked down into a scene of clanking activity. There was a mass of machinery, installations of some sort, being ,uncrated, unboxed by robos. Pieces were lifted by raise cranes, transferred to transports. But those carriers ran neither on wheels nor—
'Antigrav!' Borton leaned nearer to the edge. 'They have antigrav in small mobile units.'
Antigrav we knew. But the principle could not be used in mobile units, only installed in buildings as a method of transport from floor to floor. Here these carriers, loaded with heavy burdens, swung along in ordered lines through a dark archway in the opposite wall.
'Where's the controller?' The other Patrolman peered over.
'Remote control, I would say.' Foss stood up.
We had all fallen flat at the sign of the activity. But now Foss apparently thought we had nothing to fear. And a moment later he added:
'Those are programmed robos.'
Programmed robos! The complexity of the operation here on Sekhmet increased with every discovery we made. Programmed robos were not ordinarily ship workers, like the controlled ones we had earlier seen and used ourselves. They were far more intricate, requiring careful servicing, which made them impractical for use on primitive worlds. One did not find them on the frontier. Yet here they were at work light-years away from the civilizations producing them. Shipping these here, preparing them for work, would have been a major task in itself.
'In a jack hideout?' Foss protested.
'Look closer!' Borton was still watching below. 'This is a storehouse which is being systematically looted. And who would have situated it here in the first place—'
'Forerunners,' Lidj answered him. 'But machines —this is not a tomb, nor—'
'Nor a lot of things!' Borton interrupted. 'There were Forerunner installations found on Limbo. The only difference is that those were abandoned, not stored away. Here—perhaps a whole civilization was kept—both men and machines! And the Forerunners were not a single civilization, either—even a single species. Ask the Zacathans—they can count you off evidence of perhaps ten which have been tentatively identified, plus fragments of other, earlier ones which have not! The universe is a graveyard of vanished races, some of whom rose to heights we cannot assess today. These machines, if they can be made to work again, their purposes learned—'
