It occurred to him that Flower staff had no authority to or­der a regular from Saber to accompany him.

Stavros did.

Dark overtook them on the plateau, as Duncan had known it would, in a place where the spires were few and a vast stretch of sand lay between them and the farther cliffs.

"We might keep going," Galey volunteered, though his voice seemed strained already.

Duncan shook his head, selected a safe spot, and settled to stay until the dawn, wrapped in a thermal sheet and far more comfortable than in his previous night in this place. They re­moved the masks and ate, though Galey had small appetite; then they replaced them to sleep, turn and turn about.

A jo flew, briefly airborne, a shadow against the night sky. Once Duncan woke to Galey’s whispered insistence that he had heard something moving in the rocks. He sat watch then, while Galey slept or pretended to sleep, and far across the sands he saw the dark shadow of a hunting dus that moved into the deeper shadow of the spires and was gone..

He listened to the wind, and looked at the stars, and knew his way now beyond doubt.

At the first touch of color to the land, they folded up the blankets and set out again, shivering in the early dawn, Galey stiff and limping from his exertion of the day before.

The spires closed about them once more, stained by the ruddy sun, and still the sense of familiarity persisted. They were on the right track; there remained no vestige of doubt in Duncan's mind, but he savored the silence, and did not break it with conversation.

And eventually there lay before him that gap in the rocks, inconspicuous, like a dozen others thereabouts, save for the identifying shelf of rock that slanted down at the left, and the depth of the shadow that lay within.

Duncan paused; it occurred to him that even yet there was time to repent what he was doing, that he could lead Galey in circles until they ran out of supplies, and convince them all that he could not remember, that the place was lost to him. It would need great and skilled effort by Boaz' small staff to locate it without him. It might go unlocated for gen­erations of humans on Kesrith.

But relics did not serve a dead people. That everything they had been should perish, that an intelligent species should vanish from the universe, leaving nothing there was no tightness in that

"Here," he said, and led Galey by the way that he well remembered, that he had seen thereafter in his nightmares, that long, close passage between sandstone cliffs that leaned together and shut out the sky. The passage wound, and seemed to spiral, down into dark and cold. Duncan used his penlight, and its tiny beam showed serpentine writings on the walls, turn after turn into the depths.

Daylight broke, blinding and blurring as they arrived at the cul-de-sac that ended their descent. They stood in a deep well of living stone, open to the sky. The walls here too were writ­ten over with symbols, and blackened with the traces of fire, both the stone and the metal door that stood open at the far side of the pit.

Galey swore: the sound of the human irreverence grated On Duncan's ears, and he looked to his left, where Galey stared. A huddled mass of bones and burned tatters of black cloth rested in a niche within the stone. It was the guardian of the shrine. Niun had paid him respect; Duncan felt moved to do so and did not know how.

"Don't touch anything," he said, and immediately recalled Melein's similar words to him, a chilling echo in the deep well.

He tried to put his mind to other things knelt on the sand in the sunlight and opened up the gear that he had carried, photographic equipment, and most of all a signal device. He activated it, and knew from that moment that human presence in this place was inevitable. Searching aircraft would eventually find it.

Then with the camera he rose and recorded all that was about them, the writings, the guardian, the doorway with its broken seal, the marks of destroying fire.

And last of all he ventured into the dark, into the shrine that not even Niun had presumed to enter only Melein, with Niun to guard the door. Galey started to follow him, stepped within.

"Stay back," Duncan ordered; his voice echoed terribly in the metal chamber, and Galey halted, uncertain, in the door­way retreated when Duncan stared at him. Duncan drew a careful breath then and activated the camera and its light, by that surveying the ruin about him.

Shrine: it was rather a place of fire-stained steel, ruined panels, banks of lifeless machinery, stark and unlovely. He had known what he would find here, had heard the sound of it, the working of machinery the night the place had died, destroyed by the mri.

And yet the mri, who well understood machines, revered it revered the artifact they had borne away from it.

Mistrust recurred in him, human mistrust, the remem­brance that the mri had never offered assurances to him: they had only held their hand from him.

Banks of machinery, no trace of holiness. The thing that Niun had so lovingly carried hence, that now rested in Flower's belly, suddenly seemed sinister and threatening ... a weapon, perhaps, that could be triggered by probing. The mri penchant for taking enemies with them in their self-destruction made it entirely possible, made Niun's treasuring of it still comprehensible. Yet Boaz and security evidently had some confidence that it was no weapon.

It had its origin here here, cradled in that rest, perhaps, that now was stripped and vacant. Duncan lifted the camera, completed his work among the dead, burned banks, explored recesses where the light pierced deep shadows, where yet the wind had not swept away the ash. Boaz' people would come here next; some of the computer specialists would try the wreckage of the banks, with little hope. Melein had been thorough, protecting this place from humanity, whatever it once might have been.

He had all he needed, all he could obtain. He returned to the entry, and delayed yet again, taking in the place with a last glance, as if that could fix it all in his mind and pierce through the heart of what was mri.

"Sir?" Galey said from the well.

Duncan turned abruptly, joined Galey in the daylight, moved aside the breathing mask that suddenly seemed to re­strict his oxygen glad to draw a breath of acrid, daylit air, wind-clean. Galey's broad, anxious face seemed suddenly of another, a more welcome world.

"Let's go," he said then to Galey. "Let's get out of here.”

The lower canyon was already deep in shadow when they reached the edee of the plateau, that path among the rocks that led down into Sil'athen. It was late afternoon where they stood, and twilight down in the canyon beneath them.

"Dark's going to be on us again before we reach the ship," Duncan said.

"We going to go all the way anyway?" Galey asked.

Duncan shook his head. "No. At dusk we sit down wher­ever we are.”

Galey did not look pleased. Likely whoever had given him his orders had not well prepared him for the possibilities of nights spent in the open. Duncan's nose had started bleeding again on the return walk, irritated by the thin, dry air; Galey's cough had worsened, and if they must spend another night in the open, Galey would be suffering the like.

The regular attacked the descent first, scattering pebbles, slipping somewhat in his determination to make haste. And suddenly he stopped.

Duncan heard the aircraft at the same instant, a distant hum that grew louder, passed overhead and circled off again. He looked at Galey, and Galey likewise looked disturbed.

"Maybe it's weather moving in on us," Galey said, "or maybe it's something urgent at the port.”

Duncan had the communicator; he fingered it nervously, reckoning that if either had been the case, then there should have been a call from the aircraft. There was silence.

"Move," he said to Galey.

There was no sign of the aircraft while they worked their way down the dangerous descent. They rested hardly at all; Duncan found blood choking him, stripped off the mask and wiped his face, smearing a red streak across his hand diz­ziness blurred the rocks. He felt his way after Galey, stumbled to the valley floor, the soft and difficult sand.

"You're just out of sickbay," Galey said, offering with a touch on the straps to take the load that he carried. "Trust me with the gear at least. You'll be done up again.”

"No," he answered, blindly stubborn. He gathered his feet under him and started walking, overwhelmed with anxiety, Galey struggling to stay with him.

Another kilometer up the canyon: this much ground Duncan made before he found his limit with the load he car­ried, coughing painfully; he surrendered the gear to Galey, who labored along with him, himself suffering from the cold air, rawly gasping after each breath. It was a naked, terribly isolate feeling, walking these shadowed depths among the tombs, carrying a record that did not belong to humanity, that others desired.

And there came a regul vehicle lumbering down the can­yon, slow and ponderous. Galey swore. Duncan simply watched it come.

There was nothing to do, nowhere to go, no longer even any place to conceal the equipment. They were far from the rocks, in the center of the sandy expanse and under observa­tion from the regul.

The sled rumbled up to them and stopped. The windscreen rolled back. A regul youngling smiled a regul smile at them both, a mere opening of the mouth that showed the ridge of dentition within.

"Kose Sten Duncan," said the regul. "We grew concerned. All right? All right?”

"Entirely," he said. "Go away. We do not need help." The smile stayed. The round brown eyes flicked over his face, his hand, the equipage they carried. "Thin air. Heavy to carry, perhaps? Sit on the back, favor. I will carry you. Many bad things are here, evening coming. I am koj Suth Horag-gi. Bai Hulagh sent me. The reverence has profound concern would not wish, kose Sten Duncan, accident to a human party here in the desert. We will take you back.”

It was a small vehicle, a sled with a flatbed for cargo, where it was possible to sit without being confined: it was not imminently threatening, and it was pointless pride to refuse and keep walking, when the sled could easily match their best pace.

But Duncan did not believe the words he had been told mistrusted the regul presence entirely. Galey was not moving without him, stood waiting his cue; and with great misgivings Duncan climbed aboard the flatbed of the little vehicle. He made room for Galey, who joined him, holding the gear care­fully on his lap. The vehicle jolted into a slow turn on the sand.
