Ahead of me the tunnel opened into a wide chamber, and I saw the white form of Vertorix glimmer momentarily in the semidarkness and vanish in what appeared to be the entrance of a corridor opposite the mouth of the tunnel I had just traversed. Instantly there sounded a short, fierce shout and the crash of a hard-driven blow, mixed with the hysterical screams of a girl and a medley of serpent-like hissing that made my hair bristle. And at that instant I shot out of the tunnel, running at full speed, and realized too late the floor of the cavern lay several feet below the level of the tunnel. My flying feet missed the tiny steps and I crashed terrifically on the solid stone floor.

  Now as I stood in the semi-darkness, rubbing my aching head, all this came back to me, and I stared fearsomely across the vast chamber at that black cryptic corridor into which Tamera and her lover had disappeared, and over which silence lay like a pall. Gripping my sword, I warily crossed the great still cavern and peered into the corridor. Only a denser darkness met my eyes. I entered, striving to pierce the gloom, and as my foot slipped on a wide wet smear on the stone floor, the raw acrid scent of fresh-spilled blood met my nostrils. Someone or something had died there, either the young Briton or his unknown attacker.

  I stood there uncertainly, all the supernatural fears that are the heritage of the Gael rising in my primitive soul. I could turn and stride out of these accursed mazes, into the clear sunlight and down to the clean blue sea where my comrades, no doubt, impatiently awaited me after the routing of the Britons. Why should I risk my life among these grisly rat dens? I was eaten with curiosity to know what manner of beings haunted the cavern, and who were called the Children of the Night by the Britons, but it was my love for the yellow-haired girl which drove me down that dark tunnel–and love her I did, in my way, and would have been kind to her, had I carried her away to my island haunt.

  I walked softly along the corridor, blade ready. What sort of creatures the Children of the Night were, I had no idea, but the tales of the Britons had lent them a distinctly inhuman nature.

  The darkness closed around me as I advanced, until I was moving in utter blackness. My groping left hand encountered a strangely carven doorway, and at that instant something hissed like a viper beside me and slashed fiercely at my thigh. I struck back savagely and felt my blind stroke crunch home, and something fell at my feet and died. What thing I had slain in the dark I could not know, but it must have been at least partly human because the shallow gash in my thigh had been made with a blade of some sort, and not by fangs or talons. And I sweated with horror, for the gods know, the hissing voice of the Thing had resembled no human tongue I had ever heard.

  And now in the darkness ahead of me I heard the sound repeated, mingled with horrible slitherings, as if numbers of reptilian creatures were approaching. I stepped quickly into the entrance my groping hand had discovered and came near repeating my headlong fall, for instead of letting into another level corridor, the entrance gave onto a flight of dwarfish steps on which I floundered wildly.

  Recovering my balance I went on cautiously, groping along the sides of the shaft for support. I seemed to be descending into the very bowels of the earth, but I dared not turn back. Suddenly, far below me, I glimpsed a faint eery light. I went on, perforce, and came to a spot where the shaft opened into another great vaulted chamber; and I shrank back, aghast.

  In the center of the chamber stood a grim, black altar; it had been rubbed all over with a sort of phosphorous, so that it glowed dully, lending a semi-illumination to the shadowy cavern. Towering behind it on a pedestal of human skulls, lay a cryptic black object, carven with mysterious hieroglyphics. The Black Stone! The ancient, ancient Stone before which, the Britons said, the Children of the Night bowed in gruesome worship, and whose origin was lost in the black mists of a hideously distant past. Once, legend said, it had stood in that grim circle of monoliths called Stonehenge, before its votaries had been driven like chaff before the bows of the Picts.

  But I gave it but a passing, shuddering glance. Two figures lay, bound with rawhide thongs, on the glowing black altar. One was Tamera; the other was Vertorix, bloodstained and disheveled. His bronze ax, crusted with clotted blood, lay near the altar. And before the glowing stone squatted Horror.

  Though I had never seen one of those ghoulish aborigines, I knew this thing for what it was, and shuddered. It was a man of a sort, but so low in the stage of life that its distorted humanness was more horrible than its bestiality.

  Erect, it could not have been five feet in height. Its body was scrawny and deformed, its head disproportionately large. Lank snaky hair fell over a square inhuman face with flabby writhing lips that bared yellow fangs, flat spreading nostrils and great yellow slant eyes. I knew the creature must be able to see in the dark as well as a cat. Centuries of skulking in dim caverns had lent the race terrible and inhuman attributes. But the most repellent feature was its skin: scaly, yellow and mottled, like the hide of a serpent. A loin-clout made of a real snake’s skin girt its lean loins, and its taloned hands gripped a short stone-tipped spear and a sinister-looking mallet of polished flint.

  So intently was it gloating over its captives, it evidently had not heard my stealthy descent. As I hesitated in the shadows of the shaft, far above me I heard a soft sinister rustling that chilled the blood in my veins.

  The Children were creeping down the shaft behind me, and I was trapped. I saw other entrances opening on the chamber, and I acted, realizing that an alliance with Vertorix was our only hope. Enemies though we were, we were men, cast in the same mold, trapped in the lair of these indescribable monstrosities.

  As I stepped from the shaft, the horror beside the altar jerked up his head and glared full at me. And as he sprang up, I leaped and he crumpled, blood spurting, as my heavy sword split his reptilian heart. But even as he died, he gave tongue in an abhorrent shriek which was echoed far up the shaft. In desperate haste I cut Vertorix’s bonds and dragged him to his feet. And I turned to Tamera, who in that dire extremity did not shrink from me, but looked up at me with pleading, terror-dilated eyes. Vertorix wasted no time in words, realizing chance had made allies of us. He snatched up his ax as I freed the girl.

  “We can’t go up the shaft,” he explained swiftly; “we’ll have the whole pack upon us quickly. They caught Tamera as she sought for an exit, and overpowered me by sheer numbers when I followed. They dragged us hither and all but that carrion scattered–bearing word of the sacrifice through all their burrows, I doubt not. Il-marenin alone knows how many of my people, stolen in the night, have died on that altar. We must take our chance in one of these tunnels–all lead to hell! Follow me!”

  Seizing Tamera’s hand he ran fleetly into the nearest tunnel and I followed. A glance back into the chamber before a turn in the corridor blotted it from view showed a revolting horde streaming out of the shaft. The tunnel slanted steeply upward, and suddenly ahead of us we saw a bar of gray light. But the next instant our cries of hope changed to curses of bitter disappointment. There was daylight, aye, drifting in through a cleft in the vaulted roof, but far, far above our reach. Behind us the pack gave tongue exultingly. And I halted.

  “Save yourselves if you can,” I growled. “Here I make my stand. They can see in the dark and I cannot.

  Here at least I can see them. Go!”

  But Vertorix halted also. “Little use to be hunted like rats to our doom. There is no escape. Let us meet our fate like men.”

  Tamera cried out, wringing her hands, but she clung to her lover.

  “Stand behind me with the girl,” I grunted. “When I fall, dash out her brains with your ax lest they take her alive again. Then sell your own life as high as you may, for there is none to avenge us.”

  His keen eyes met mine squarely.

  “We worship different gods, reaver,” he said, “but all gods love brave men. Mayhap we shall meet again, beyond the Dark.”

  “Hail and farewell, Briton!” I growled, and our right hands gripped like steel.

>   “Hail and farewell, Gael!”

  And I wheeled as a hideous horde swept up the tunnel and burst into the dim light, a flying nightmare of streaming snaky hair, foam-flecked lips and glaring eyes. Thundering my war-cry I sprang to meet them and my heavy sword sang and a head spun grinning from its shoulder on an arching fountain of blood.

  They came upon me like a wave and the fighting madness of my race was upon me. I fought as a maddened beast fights and at every stroke I clove through flesh and bone, and blood spattered in a crimson rain.

  Then as they surged in and I went down beneath the sheer weight of their numbers, a fierce yell cut the din and Vertorix’s ax sang above me, splattering blood and brains like water. The press slackened and I staggered up, trampling the writhing bodies beneath my feet.

  “A stair behind us!” the Briton was screaming. “Half hidden in an angle of the wall! It must lead to daylight! Up it, in the name of Il-marenin!”

  So we fell back, fighting our way inch by inch. The vermin fought like blood-hungry devils, clambering over the bodies of the slain to screech and hack. Both of us were streaming blood at every step when we reached the mouth of the shaft, into which Tamera had preceded us.

  Screaming like very fiends the Children surged in to drag us down. The shaft was not as light as had been the corridor, and it grew darker as we climbed, but our foes could only come at us from in front. By the gods, we slaughtered them till the stair was littered with mangled corpses and the Children frothed like mad wolves! Then suddenly they abandoned the fray and raced back down the steps.

  “What portends this?” gasped Vertorix, shaking the bloody sweat from his eyes.

  “Up the shaft, quick!” I panted. “They mean to mount some other stair and come at us from above!”

  So we raced up those accursed steps, slipping and stumbling, and as we fled past a black tunnel that opened into the shaft, far down it we heard a frightful howling. An instant later we emerged from the shaft into a winding corridor, dimly illumined by a vague gray light filtering in from above, and somewhere in the bowels of the earth I seemed to hear the thunder of rushing water. We started down the corridor and as we did so, a heavy weight smashed on my shoulders, knocking me headlong, and a mallet crashed again and again on my head, sending dull red flashes of agony across my brain. With a volcanic wrench I dragged my attacker off and under me, and tore out his throat with my naked fingers. And his fangs met in my arm in his death-bite.

  Reeling up, I saw that Tamera and Vertorix had passed out of sight. I had been somewhat behind them, and they had run on, knowing nothing of the fiend which had leaped on my shoulders. Doubtless they thought I was still close on their heels. A dozen steps I took, then halted. The corridor branched and I knew not which way my companions had taken. At blind venture I turned into the left-hand branch, and staggered on in the semidarkness. I was weak from fatigue and loss of blood, dizzy and sick from the blows I had received. Only the thought of Tamera kept me doggedly on my feet. Now distinctly I heard the sound of an unseen torrent.

  That I was not far underground was evident by the dim light which filtered in from somewhere above, and I momentarily expected to come upon another stair. But when I did, I halted in black despair; instead of up, it led down. Somewhere far behind me I heard faintly the howls of the pack, and I went down, plunging into utter darkness. At last I struck a level and went along blindly. I had given up all hope of escape, and only hoped to find Tamera–if she and her lover had not found a way of escape–and die with her. The thunder of rushing water was above my head now, and the tunnel was slimy and dank. Drops of moisture fell on my head and I knew I was passing under the river.

  Then I blundered again upon steps cut in the stone, and these led upward. I scrambled up as fast as my stiffening wounds would allow–and I had taken punishment enough to have killed an ordinary man. Up I went and up, and suddenly daylight burst on me through a cleft in the solid rock. I stepped into the blaze of the sun. I was standing on a ledge high above the rushing waters of a river which raced at awesome speed between towering cliffs. The ledge on which I stood was close to the top of the cliff; safety was within arm’s length. But I hesitated and such was my love for the golden-haired girl that I was ready to retrace my steps through those black tunnels on the mad hope of finding her. Then I started.

  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 river-bed. 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. Tamera 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 mus
cles. 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.
