Across the river I saw another cleft in the cliff-wall which fronted me, with a ledge similar to that on which I stood, but longer. In olden times, I doubt not, some sort of primitive bridge connected the two ledges— possibly before the tunnel was dug beneath the riverbed. Now as I watched, two figures emerged upon that other ledge—one gashed, dust-stained, limping, gripping a bloodstained ax; the other slim, white and girlish.
Vertorix and Tamera! They had taken the other branch of the corridor at the fork and had evidently followed the windows of the tunnel to emerge as I had done, except that I had taken the left turn and passed clear under the river. And now I saw that they were in a trap. On that side the cliffs rose half a hundred feet higher than on my side of the river, and so sheer a spider could scarce have scaled them. There were only two ways of escape from the ledge: back through the fiend-haunted tunnels, or straight down to the river which raved far beneath.
I saw Vertorix look up the sheer cliffs and then down, and shake his head in despair. Tamara put her arms about his neck, and though I could not hear their voices for the rush of the river, I saw them smile, and then they went together to the edge of the ledge. And out of the cleft swarmed a loathsome mob, as foul reptiles writhe up out of the darkness, and they stood blinking in the sunlight like the night-things they were. I gripped my sword-hilt in the agony of my helplessness until the blood trickled from under my fingernails. Why had not the pack followed me instead of my companions?
The Children hesitated an instant as the two Britons faced them, then with a laugh Vertorix hurled his ax far out into the rushing river, and turning, caught Tamera in a last embrace. Together they sprang far out, and still locked in each other's arms, hurtled downward, struck the madly foaming water that seemed to leap up to meet them, and vanished. And the wild river swept on like a blind, insensate monster, thundering along the echoing cliffs.
A moment I stood frozen, then like a man in a dream I turned, caught the edge of the cliff above me and wearily drew myself up and over, and stood on my feet above the cliffs, hearing like a dim dream the roar of the river far beneath.
I reeled up, dazedly clutching my throbbing head, on which dried blood was clotted. I glared wildly about me. I had clambered the cliffs—no, by the thunder of Crom, I was still in the cavern! I reached for my sword —
The mists faded and I stared about dizzily, orienting myself with space and time. I stood at the foot of the steps down which I had fallen. I who had been Conan the reaver, was John O'Brien. Was all that grotesque interlude a dream? Could a mere dream appear so vivid? Even in dreams, we often know we are dreaming, but Conan the reaver had no cognizance of any other existence. More, he remembered his own past life as a living man remembers, though in the waking mind of John O'Brien, that memory faded into dust and mist. But the adventures of Conan in the Cavern of the Children stood clear-etched in the mind of John O'Brien.
I glanced across the dim chamber toward the entrance of the tunnel into which Vertorix had followed the girl. But I looked in vain, seeing only the bare blank wall of the cavern. I crossed the chamber, switched on my electric torch—miraculously unbroken in my fall—and felt along the wall.
Ha! I started, as from an electric shock! Exactly where the entrance should have been, my fingers detected a difference in material, a section which was rougher than the rest of the wall. I was convinced that it was of comparatively modern workmanship; the tunnel had been walled up.
I thrust against it, exerting all my strength, and it seemed to me that the section was about to give. I drew back, and taking a deep breath, launched my full weight against it, backed by all the power of my giant muscles. The brittle, decaying wall gave way with a shattering crash and I catapulted through in a shower of stones and falling masonry.
I scrambled up, a sharp cry escaping me. I stood in a tunnel, and I could not mistake the feeling of similarity this time. Here Vertorix had first fallen foul of the Children, as they dragged Tamera away, and here where I now stood the floor had been awash with blood.
I walked down the corridor like a man in a trance. Soon I should come to the doorway on the left—aye, there it was, the strangely carven portal, at the mouth of which I had slain the unseen being which reared up in the dark beside me. I shivered momentarily. Could it be possible that remnants of that foul race still lurked hideously in these remote caverns?
I turned into the doorway and my light shone down a long, slanting shaft, with tiny steps cut into the solid stone. Down these had Conan the reaver gone groping and down them went I, John O'Brien, with memories of that other life filling my brain with vague phantasms. No light glimmered ahead of me but I came into the great dim chamber I had known of yore, and I shuddered as I saw the grim black altar etched in the gleam of my torch. Now no bound figures writhed there, no crouching horror gloated before it. Nor did the pyramid of skulls support the Black Stone before which unknown races had bowed before Egypt was born out of time's dawn. Only a littered heap of dust lay strewn where the skulls had upheld the hellish thing. No, that had been no dream: I was John O'Brien, but I had been Conan of the reavers in that other life, and that grim interlude a brief episode of reality which I had relived.
I entered the tunnel down which we had fled, shining a beam of light ahead, and saw the bar of gray light drifting down from above—just as in that other, lost age. Here the Briton and I, Conan, had turned at bay. I turned my eyes from the ancient cleft high up in the vaulted roof, and looked for the stair. There it was, half-concealed by an angle in the wall.
I mounted, remembering how hurriedly Vertorix and I had gone up so many ages before, with the horde hissing and frothing at our heels. I found myself tense with dread as I approached the dark, gaping entrance through which the pack had sought to cut us off. I had snapped off the light when I came into the dim-lit corridor below, and now I glanced into the well of blackness which opened on the stair. And with a cry I started back, nearly losing my footing on the worn steps. Sweating in the semidarkness I switched on the light and directed its beam into the cryptic opening, revolver in hand.
I saw only the bare rounded sides of a small shaftlike tunnel and I laughed nervously. My imagination was running riot; I could have sworn that hideous yellow eyes glared terribly at me from the darkness, and that a crawling something had scuttered away down the tunnel. I was foolish to let these imaginings upset me. The Children had long vanished from these caverns; a nameless and abhorrent race closer to the serpent than the man, they had centuries ago faded back into the oblivion from which they had crawled in the black dawn ages of the Earth.
I came out of the shaft into the winding corridor, which, as I remembered of old, was lighter. Here from the shadows a lurking thing had leaped on my back while my companions ran on, unknowing. What a brute of a man Conan had been, to keep going after receiving such savage wounds! Aye, in that age all men were iron.
I came to the place where the tunnel forked and as before I took the left- hand branch and came to the shaft that led down. Down this I went, listening for the roar of the river, but not hearing it. Again the darkness shut in about the shaft, so I was forced to have recourse to my electric torch again, lest I lose my footing and plunge to my death. Oh, I, John O'Brien, am not nearly so sure-footed as was I, Conan the reaver; no, nor as tigerishly powerful and quick, either.
I soon struck the dank lower level and felt again the dampness that denoted my position under the riverbed, but still I could not hear the rush of the water. And indeed I knew that whatever mighty river had rushed roaring to the sea in those ancient times, there was no such body of water among the hills today. I halted, flashing my light about. I was in a vast tunnel, not very high of roof, but broad. Other smaller tunnels branched off from it and I wondered at the network which apparently honeycombed the hills.
