Carse seemed to plunge through a nighted abyss, buffeted by all the shrieking winds of space. An endless, endless fall with the timelessness and the choking horror of a nightmare.
He struggled with the fierce revulsion of an animal trapped by the unknown. His struggle was not physical, for in that blind and screaming nothingness his body was useless. It was a mental fight, the man’s inner core of courage reasserting itself, willing itself to stop this nightmare fall through darkness.
And then as he fell, a more terrifying sensation shook him. A feeling that he was not alone in this nightmare plunge through infinity, that a dark strong, pulsating presence was close beside him, grasping for him, groping with eager fingers for his brain.
Carse made a supreme desperate mental effort. His sensation of falling seemed to lessen and then he felt solid rock slipping under his hands and feet. He scrambled frantically forward, in physical effort this time.
He found himself quite suddenly outside the dark bubble again on the floor of the inner chamber of the Tomb.
“What in the Nine Hells…” he began shakily and then stopped because the oath seemed so pitifully inadequate for what had happened.
The little krypton-lamp hooked to his belt still cast its reddish glow, the sword of Rhiannon still glittered in his hand.
And the bubble of darkness still gloomed and brooded a foot away from him, flickering with its whirl of diamond motes.
Carse realized that all his nightmare plunging through space had been during the moment he was inside the bubble. What devil’s trick of ancient science was the thing anyway? Some queer perpetual vortex of force that the mysterious Quiru of long ago had set up, he supposed.
But why had he seemed to fall through infinities inside the thing? And whence had come that terrifying sensation of strong fingers groping eagerly at his brain as he fell?
“A trick of old Quiru science,” he muttered shakenly. “And Penkawr’s superstitions made him think he could kill me by pushing me into it.”
Penkawr? Carse leaped to his feet, the sword of Rhiannon glittering wickedly in his hand.
“Blast his thieving little soul!”
Penkawr was not here now. But he wouldn’t have had time to go far. The smile on Carse’s face was not pleasant as he went through the doorway.
In the outer chamber he suddenly stopped dead. There were things here now—big strange glittering objects—that had not been here before.
Where had they come from? Had he been longer in that bubble of darkness than he thought? Had Penkawr found these things in hidden crypts and arranged them here to await his return?
Carse’s wonder increased as he examined the objects that now loomed amid the mail and other relics he had seen before. These objects did not look like mere art-relics—they looked like carefully fashioned, complicated instruments of unguessable purpose.
The biggest of them was a crystal wheel, the size of a small table, mounted horizontally atop a dull metal sphere. The wheel’s rim glistened with jewels cut in precise polyhedrons. And there were other smaller devices of linked crystal prisms and tubes and things built of concentric metal rings and squat looped tubes of massive metal.
Could these glittering objects be the incomprehensible devices of an ancient alien Martian science? That supposition seemed incredible. The Mars of the far past, scholars knew, had been a world of only rudimentary science, a world of sword-fighting sea-warriors whose galleys and kingdoms had clashed on long-lost oceans.
Yet, perhaps, in the Mars of the even farther past, there had been a science whose techniques were unfamiliar and unrecognizable?
“But where could Penkawr have found them when we didn’t see them before? And why didn’t he take any of them with him?”
Memory of Penkawr reminded him that the little thief would be getting farther away every moment. Grimly gripping the sword, Carse turned and hurried down the square stone corridor toward the outer world.
As he strode on Carse became aware that the air in the tomb was now strangely damp. Moisture glistened on the walls. He had not noticed that most un-Martian dampness before and it startled him.
“Probably seepage from underground springs, like those that feed the canals,” he thought. “But it wasn’t there before.”
His glance fell on the floor of the corridor. The drifted dust lay over it thickly as when they had entered. But there were no footprints in it now. No prints at all except those he was now making.
A horrible doubt, a feeling of unreality, clawed at Carse. The un-Martian dampness, the vanishing of their footprints—what had happened to everything in the moment he’d been inside the dark bubble?
He came to the end of the square stone corridor. And it was closed. It was closed by a massive slab of monolithic stone.
Carse stopped, staring at the slab. He fought down his increasing sense of weird unreality and made explanation for himself.
“There must have been a stone door I didn’t see—and Penkawr has closed it to lock me in.”
He tried to move the slab. It would not budge nor was there any sign of key, knob or hinge.
Finally Carse stepped back and leveled his proton-pistol. Its hissing streak of atomic flame crackled in the rock slab, searing and splitting it.
The slab was thick. He kept the trigger of his gun depressed for minutes. Then, with a hollowly reverberating crash the fragments of the split slab fell back in toward him.
But beyond, instead of the open air, there lay a solid mass of dark red soil.
“The whole Tomb of Rhiannon—buried, now; Penkawr must have started a cave-in.”
Carse didn’t believe that. He didn’t believe it at all but he tried to make himself believe, for he was becoming more and more afraid. And the thing of which he was afraid was impossible.
With blind anger he used the flaming beam of the pistol to undercut the mass of soil that blocked his way. He worked outward until the beam suddenly died as the charge of the gun ran out. He flung away the useless pistol and attacked the hot smoking mass of soil with the sword.
Panting, dripping, his mind a whirl of confused speculations, he dug outward through the soft soil till a small hole of brilliant daylight opened in front of him.
Daylight? Then he’d been in the weird bubble of darkness longer than he had imagined.
The wind blew in through the little opening, upon his face. And it was warm wind. A warm wind and a damp wind, such as never blows on desert Mars.
Carse squeezed through and stood in the bright day looking outward.
There are times when a man has no emotion, no reaction. Times when all the centers are numbed and the eyes see and the ears hear but nothing communicates itself to the brain, which is protected in this way from madness.
He tried finally to laugh at what he saw though he heard his own laughter as a dry choking cry.
“Mirage, of course,” he whispered. “A big mirage. Big as all Mars.”
The warm breeze lifted Carse’s tawny hair, blew his cloak against him. A cloud drifted over the sun and somewhere a bird screamed harshly. He did not move.
He was looking at an ocean.
It stretched out to the horizon ahead, a vast restlessness of water, milky-white and pale with a shimmering phosphorescence even in daylight.
“Mirage,” he said again stubbornly, his reeling mind clinging with the desperation of fear to that one shred of explanation. “It has to be. Because this is still Mars.”
Still Mars, still the same planet. The same high hills up into which Penkawr had led him by night.
Or were they the same? Before, the foxhole entrance to the Tomb of Rhiannon had been in a steep cliff-face. Now he stood on the grassy slope of a great hill.
And there were rolling green hills and dark forest down there below him, where before had been only desert. Green hills, green wood and a bright river that ran down a gorge to what had been dead sea-bottom but was now—sea.
Carse’s numbed gaze swept along the great coast of the distant shoreline. And down on that far sunlight coast he saw the glitter of a white city and knew that it was Jekkara.
Jekkara, bright and strong between the verdant hills and the mighty ocean, that ocean that had not been seen upon Mars for nearly a million years.
Matthew Carse knew then that it was no mirage. He sat and hid his face in his hands. His body was shaken by deep tremors and his nails bit into his own flesh until blood trickled down his cheeks.
He knew now what had happened to him in that vortex of darkness, and it seemed to him that a cold voice repeated a certain warning inscription in tones of distant thunder.
“The Quiru are lords of space and time— of time— OF TIME!”
Carse, staring out over the green hills and the milky ocean, made a terrible effort to grapple with the incredible.
“ I have come into the past of Mars. All my life I have studied and dreamed of that past. Now I am in it. I, Matthew Carse, archaeologist, renegade, looter of tombs.
“ The Quiru for their own reasons built a way and I came through it. Time is to us the unknown dimension but the Quiru knew it!”
Carse had studied science. You had to know the elements of a half-dozen sciences to be a planetary archaeologist. He frantically ransacked memory now for an explanation.
Had his first guess about that bubble of darkness been right? Was it really a hole in the continuum of the universe? If that were so he could dimly understand what had happened to him.
For the space-time continuum of the universe was finite, limited. Einstein and Riemann had proved that long ago. And he had fallen clear out of that continuum and then back into it again—but into a different time-frame from his own.
What was it that Kaufman had once written? “The Past is the Present-that-exists-at-a-distance.” He had come back into that other distant Present, that was all. There was no reason to be afraid.
But he was afraid. The horror of that nightmare transition to this green and smiling Mars of long ago wrenched a gusty cry from his lips.
Blindly, still gripping the jewelled sword, he leaped up and turned to re-enter the buried Tomb of Rhiannon.
“I can go back the way I came, back through that hole in the continuum.”
He stopped a convulsive shudder running through his frame. He could not make himself face again that bubble of glittering gloom, that dreadful plunge through inter-dimensional infinity.
He dared not. He had not the Quiru’s wisdom. In that perilous plunge across time mere chance had flung him into his past age. He could not count on chance to return him to his own far-future age.
“I’m here,” he said. “I’m here in the distant past of Mars and I’m here to stay.”
He turned back around and gazed out again upon that incredible vista. He stayed there a long time, unmoving. The sea birds came and looked at him and flashed away on their sharp white wings. The shadows lengthened.
His eyes swung again to the white towers of Jekkara down in the distance, queenly in the sunlight above the harbor. It was not the Jekkara he knew, the thieves’ city of the Low Canals, rotting away into dust, but it was a link to the familiar and Carse desperately needed such a link.
He would go to Jekkara. And he would try not to think. He must not think at all or surely his mind would crack.
Carse gripped the haft of the jeweled sword and started down the grassy slope of the hill.
