I sprang back and away from them, electrified with terror, sick with loathing, and the black army inched itself unendingly with nightmare swiftness from the unsealed abyss, like the nauseous vomit of horror-sated hells. As it poured toward us, burying Octave’s body from sight in a writhing wave, I saw a stir of life from the seemingly dead thing I had cast aside, and saw the loathly struggle which it made to right itself and join the others.
But neither I nor my companions could endure to look longer. We turned and ran between the mighty rows of urns, with the slithering mass of demon leeches close upon us, and scattered in blind panic when we came to the first division of the vaults. Heedless of each other or of anything but the urgency of flight, we plunged into the ramifying passages at random. Behind me, I heard someone stumble and go down, with a curse that mounted to an insane shrieking; but I knew that if I halted and went back, it would only be to invite the same baleful doom that had overtaken the hindmost of our party.
Still clutching the electric torch and my open clasp-knife, I ran along a minor passage which, I seemed to remember, would conduct with more or less directness upon the large outer vault with the painted floor. Here I found myself alone. The others had kept to the main catacombs; and I heard far off a muffled babel of mad cries, as if several of them had been seized by their pursuers.
It seemed that I must have been mistaken about the direction of the passage; for it turned and twisted in an unfamiliar manner, with many intersections, and I soon found that I was lost in the black labyrinth, where the dust had lain unstirred by living feet for inestimable generations. The cinerary warren had grown still once more; and I heard my own frenzied panting, loud and stertorous as that of a Titan in the dead silence.
Suddenly, as I went on, my torch disclosed a human figure coming toward me in the gloom. Before I could master my startlement, the figure had passed me with long, machine-like strides, as if returning to the inner vaults. I think it was Harper, since the height and build were about right for him; but I am not altogether sure, for the eyes and upper head were muffled by a dark, inflated cowl, and the pale lips were locked as if a silence of tetanic torture–or death. Whoever he was, he had dropped his torch; and he was running blindfolded, in utter darkness, beneath the impulsion of that unearthly vampirism, to seek the very fountainhead of the unloosed horror. I knew that he was beyond human help; and I did not even dream of trying to stop him.
Trembling violently, I resumed my flight, and was passed by two more of our party, stalking by with mechanical swiftness and sureness, and cowled with those Satanic leeches. The others must have returned by way of the main passages; for I did not meet them; and I was never to see them again.
The remainder of my flight is a blur of pandemonian terror. Once more, after thinking that I was near the outer cavern, I found myself astray, and fled through a ranged eternity of monstrous urns, in vaults that must have extended for an unknown distance beyond our explorations. It seemed that I had gone on for years; and my lungs were choking with the aeon-dead air, and my legs were ready to crumble beneath me, when I saw far-off a tiny point of blessed daylight. I ran toward it, with all the terrors of the alien darkness crowding behind me, and accursed shadows flittering before, and saw that the vault ended in a low, ruinous entrance, littered by rubble on which there fell an arc of thin sunshine.
It was another entrance than the one by which we had penetrated this lethal underworld. I was within a dozen feet of the opening when, without sound or other intimation, something dropped upon my head from the roof above, blinding me instantly and closing upon me like a tautened net. My brow and scalp, at the same time, were shot through with a million needle-like pangs–a manifold, ever-growing agony that seemed to pierce the very bone and converge from all sides upon my inmost brain.
The terror and suffering of that moment were worse than aught which the hells of earthly madness or delirium could ever contain. I felt the foul, vampiric clutch of an atrocious death–and of more than death.
I believe that I dropped the torch; but the fingers of my right hand had still retained the open knife. Instinctively–since I was hardly capable of conscious volition–I raised the knife and slashed blindly, again and again, many times, at the thing that had fastened its deadly folds upon me. The blade must have gone through and through the clinging monstrosity, to gash my own flesh in a score of places; but I did not feel the pain of those wounds in the million-throbbing torment that possessed me.
At last I saw light, and saw that a black strip, loosened from above my eyes and dripping with my own blood, was hanging down my cheek. It writhed a little, even as it hung, and I ripped it away, and ripped the other remnants of the thing, tatter by oozing, bloody tatter, from off my brow and head. Then I staggered toward the entrance; and the wan light turned to a far, receding, dancing flame before me as I lurched and fell outside the cavern–a flame that fled like the last star of creation above the yawning, sliding chaos and oblivion into which I descended. . .
I am told that my unconsciousness was of brief duration. I came to myself, with the cryptic faces of the two Martian guides bending over me. My head was full of lancinating pains, and half-remembered terrors closed upon my mind like the shadows of mustering harpies. I rolled over, and looked back toward the cavern-mouth, from which the Martians, after finding me, had seemingly dragged me for some little distance. The mouth was under the terraced angle of an outer building, and within sight of our camp.
I stared at the black opening with hideous fascination, and descried a shadowy stirring in the gloom–the writhing, verminous movement of things that pressed forward from the darkness but did not emerge into the light. Doubtless they could not endure the sun, those creatures of ultra-mundane night and cycle-sealed corruption.
It was then that the ultimate horror, the beginning madness, came upon me. Amid my crawling revulsion, my nausea-prompted desire to flee from that seething cavern-mouth, there rose an abhorrently conflicting impulse to return; to thread my backward way through all the catacombs, as the others had done; to go down where never men save they, the inconceivably doomed and accursed, had ever gone; to seek beneath that damnable compulsion a nether world that human thought can never picture. There was a black light, a soundless calling, in the vaults of my brain: the implanted summons of the Thing, like a permeating and sorcerous poison. It lured me to the subterranean door that was walled up by the dying people of Yoh-Vombis, to immure those hellish and immortal leeches, those dark parasites that engraft their own abominable life on the half-eaten brains of the dead. It called me to the depths beyond, where dwell the noisome, necromantic Ones, of whom the leeches, with all their powers of vampirism and diabolism, are but the merest minions. . .
It was only the two Aihais who prevented me from going back. I struggled, I fought them insanely as they strove to retard me with their spongy arms; but I must have been pretty thoroughly exhausted from all the superhuman adventures of the day; and I went down once more, after a little, into fathomless nothingness, from which I floated out at long intervals, to realize that I was being carried across the desert toward Ignarh.
Well, that is all my story. I have tried to tell it fully and coherently, at a cost that would be unimaginable to the sane. . . to tell it before the madness falls upon me again, as it will very soon–as it is doing now. . . Yes, I have told my story. . . and you have written it all out, haven’t you? Now I must go back to Yoh-Vombis–back across the desert and down through all the catacombs to the vaster vaults beneath. Something is in my brain, that commands me and will direct me. . . I tell you, I must go. . .
POSTSCRIPT
As an interne in the terrestrial hospital at Ignarh, I had charge of the singular case of Rodney Severn, the one surviving member of the Octave Expedition to Yoh-Vombis, and took down the above story from his dictation. Severn had been brought to the hospital by the Martian guides of the Expedition. He was suffering from a horribly lacerated and inflamed condition of the scalp and brow, and was wildly delirious part of the time and had to be held down in his bed during recurrent seizures of a mania whose violence was doubly inexplicable in view of his extreme debility.
