He began to pick his way through the fungi, doing his best to avoid passing near them, for it seemed very repugnant to him that one of those blindly reaching grey members should touch him. Armitage was thankful when the last of the hateful nodding things was out of reach, for there was an extensive cleared space around each tower. The seeker decided to enter the central steeple; they seemed alike, each being about thirty feet high, without windows, as on the lightless planet of their origin, with a peculiarly angled doorway revealing stairs climbing up into total blackness. Armitage, however, had carried a torch with him, and, shining it up the alien passage, he forced himself to enter the somehow terrible building, reminding himself of the incantation. Armitage's steps rang hollowly on the carven stairs, seeming to resound through illimitable gulfs of space. The darkness which barred the way ahead and soon closed in behind seemed to have an almost tangible quality, and the seeker disliked the way the blackness seemed to move and twist beyond the radius of his torch-beam. He knew that the tower was windowless only because the buildings had no windows on lightless Yuggoth, but his mind would persist in conjecturing what blasphemous abnormalities the lack of windows might hide in the tower. One could never be sure what might be standing around the bend in the dizzyingly spiralling steps, and those hieroglyphics and crude drawings of fabulous spheres beyond were not comforting to the thoughts of the climber in the dark.
He had been ascending the lightless stairs for some time when he became aware of a strange feeling, as if he was about to suffer some terrible psychic displacement. There was no apparent reason why he should imagine such eldritch ideas, but it seemed as though he was about to be dragged forth from his body, or fall into some bottomless charnel pit. Those strange hieroglyphic characters all seemed to be indicating something unseen around that ever-present bend in the passageway. Was it simply a trick of light or vision that there appeared to be no steps above a certain point, and nothing except a totally dark expanse which even his torch's light would not penetrate? He drew back in affright, but once again curiosity overcame disquiet, and he continued to ascend the stairs. Upon reaching that anomalous wall of blackness, he closed his eyes involuntarily and rose one more step into the unseen section of the passage beyond the barrier.
Armitage cried out as he fell on the steps at the other side. It was as if his body had been momentarily torn apart into atoms and recombined in an infinitesimal instant. The agony he had suffered had never registered on his brain, but there was a memory of unspeakable psychic torture, resembling a memory from another life. He now lay on stairs seemingly a continuation of the steps on the other side of the barrier, but different in several essential respects. For one thing, the others had been bare and worn away; these, however, were covered with mineral dust. The walls, too, were grown with small glistening fungi, obviously of a type not seen in sane places of the world, instead of the curious, sometimes disturbingly alien hieroglyphics.
When he had recovered from that indescribable sensation, Armitage continued up the stairs. Though he felt as if he had been changed physically in some non-visible way, he noticed that the torch, to which he had clung through all that unendurable instant, still lit when he pressed the stud. He held the torch out in front of him, the beam stretching out some five feet from the ground. He rounded the inevitable bend in the stairs, and shone the ray into a face.
What that face was like, and of what body it was the face, he does not dare to tell. There are certain things which are better known by no sane man. If the whole truth about certain cosmic relationships, and the implication of the beings which exist in certain spheres, were known by the world, the whole of the human race would be shrieking in terror and gibbering for oblivion. And the thing which Armitage saw at last—one of those hideous crustacean beings which had come through space from the rim-world—" one such cosmically terrible being. But even though his mind shrivelled up inside his skull at the unspeakable sight which leered and hopped before him in the light of the torch, Armitage had enough composure left to scream that painfully sought incantation at the monstrosity. It seemed to cringe—though it was difficult to correlate the motions of something so grotesquely proportioned and abnormally shaped—and clattered off down the steps. As it reached that black barrier across the stairs, it seemed to grow infinitely huge and become something even more monstrous, before it shrank to an infinitesimal point on the ebony curtain and disappeared altogether, as the clattering claws became silent.
Reeling against the lichenous wall, Armitage attempted to forget that fungoid abomination which had burst on him around that corner. As his mind returned to equilibrium from that seething void of suspicion, he began to climb again, not thinking of what might yet lurk in the upper regions of the tower. The darkness now seemed even more material, as if at any moment it might close in on the hapless Armitage.
It was about the time that Armitage began to realise that he had been climbing the darkened stairway far longer than he should have in a thirty foot tower that he saw the ceiling of the tower. The nitrous, dripping rock seemed to meet the stairs with no means of exit, but almost immediately he saw the curiously-angled trapdoor where steps and ceiling met. Now came the time of ultimate hesitation. Why would a trapdoor open out onto a circular roof, thirty feet above the ground, of small diameter? What nameless terror might await the opening of the trapdoor? But, having come this far, he did not wish to pass through that barrier of agony without having glimpsed what might lie above. So he pushed the door open with his shoulders and stepped out on the roof.
Even in his lunacy, Armitage does not pretend to have a plausible explanation for certain aspects of his fantastic tale. He insists that the barrier across the passageway was not as meaningless as sanity would have it appear, and thinks it was in reality a barrier between points that should have been millions of miles apart, had it not been for some awful tampering with the structure of the cosmos. He seems to conjecture that the barrier changed him bodily—otherwise, according to his story, the circumstances in which he found himself would have led to asphyxiation and burst lungs with the first breath he took on that other side of the barrier. He explains that the abominations of the plateau did not capture him because he shrieked the incantation incessantly as he plunged down the tower's stairway and climbed back feverishly down the Devil's Steps. None of this may be disproved—and as for those disturbing hints concerning "bodily changes," X-ray examinations show certain modifications of the lungs and other organs for which the doctors cannot easily account.
As he clambered on the roof, Armitage wondered if the sight of that stunted horror on the stairs had already unhinged his mind. How could he not have noticed these towers which his torch's beams picked out on every side as far as its light would reach? And how could it now be black night, when he had reached the Devil's Steps well before midday? His torch, shining down the side of his vantage tower, showed black streets where abominable blasphemies moved among hideous gardens of those greyish nodding fungi and vast black windowless towers.
Confused and terrified, he stared out at the ebony void of space which stretched infinitely away from him, and of the crystalline, distorted stars which shimmered in the gulf. Then he stared again in growing, horrible realisation at those far-off constellations—and their positions. For the positions of the constellations were never seen thus on Earth; and Edward Wingate Armitage knew in that cataclysmic instant that this place of fungoid gardens and streets of windowless stone towers, whither he had come through that barrier between dimensions, was none other than Yuggoth.
