Northwest of Earth

by C. L. Moore

  Once in the very long-past days, so the little whispering fanatic had said, Mars was a green world. Seas had spread here, lapping the feet of gentler mountains, and in the slopes of those hills a mighty city once lay—a nameless city, so far as the present generations of man remembered, and a nameless star shone down upon it from a spot in the heavens now empty—the Lost Planet, shining on a lost city. The dwellers there must have seen the catastrophe which blasted that sister planet from the face of the sky. And if the little man were right, the gods of that Lost Planet had been saved from the wreckage and spirited across the void to a dwelling-place in this greatly honored city of the mountains that is not even a memory today.

  And time passed, so the story went. The city aged—the gods aged—the planet aged. At last, in some terrible catastrophe, the planet heaved under the city’s foundations, the mountains shook it into ruins and folded themselves into new and dreadful shapes. The seas receded, the fertile soil sloughed away from the rocks and time swallowed up the very memory of that city which once had been the dwelling-place of gods—which was still, so the hoarse whisper had told them, the dwelling-place of gods.

  “Must have been right around here somewhere,” said Smith, “that those two found the cave.”

  “Out around the slope to the left,” agreed Yarol. “Let’s go.” He squinted up at the feeble sun. “Not very long past dawn. We ought to be back again by dark if things go right.”

  They left the ship in its shelter and struck out across the salt drylands, the harsh scrub brushing about their knees and their breath clouding the thin air as they advanced. The slope curved away to the left, rising in rapid ascent to black peaks that were unscalable and forbidding. The only hope of penetrating that wall lay in finding the cavern that their predecessors had fled … and in that cavern—Smith loosened the heat-gun in its holster at his side.

  They had plodded for fifteen minutes through the scrub, dry snow rising under their feet and the harsh salt air frosting their breath, before the mouth of the cave they were hunting appeared darkly under the overhanging rock they had been told of.

  The two peered in doubtfully. That jagged floor might never have known the tread of human feet, so far as one might know by the look of it. Powdered snow lay undisturbed in the deep crannies, and daylight did not penetrate very far into the forbidding dark beyond. Smith drew his gun, took a deep breath and plunged into the blackness and the cold, with Yarol at his heels.

  It was like leaving everything human and alive for some frosty limbo that had never known life. The cold struck sharply through their leather garments. They took out their Tomlinson tubes before they had gone more than twenty paces, and the twin beams illumined a scene of utter desolation, more dead than death, for it seemed never to have known life.

  For perhaps fifteen minutes they stumbled through the cold dark. Smith kept his beam focused on the floor beneath them; Yarol’s roved the walls and pierced the blackness ahead. Rough walls and ragged ceiling and teeth of broken stone projecting from the floor to slash at their boots—no sound but their footsteps, nothing but the dark and the frost and the silence. Then Yarol said, “It’s foggy in here,” and something clouded the clear beams of the lights for an instant; then darkness folded round them as suddenly and completely as the folds of a cloak.

  Smith stopped dead-still, tense and listening. No sound. He felt the lens of his light-tube and knew that it still burned—it was warm, and the faint vibration under the glass told him that the tubes still functioned. But something intangible and strange blotted it out at the source … a thick, stifling blackness that seemed to muffle their senses. It was like a bandage over the eyes—Smith, holding the burning light-lens to his eyes, could not detect even its outline in that all-cloaking dark.

  For perhaps five minutes that dead blackness held them. Vaguely they knew what to expect, but when it came, the shock of it took their breath away. There was no sound, but quite suddenly around a bend of the cavern came a figure of utter whiteness, seen at first fragmentarily through a screen of rock-toothed jags, then floating full into view against the background of the dark. Smith thought he had never seen whiteness before until his incredulous eyes beheld this creature—if creature it could be. Somehow he thought it must be partly below the level of the floor along which it moved; for though in that blind black he had no way of gauging elevation, it seemed to him that the apparition, moving with an effortless glide, advanced unopposed through the solid rock of the floor. And it was whiter than anything living or dead had ever been before—so white that it sickened him, somehow, and the flesh crept along his spine. Like a cut-out figure of paper, it blazed against the flat black beyond. The dark did not affect it, no shadows lay upon its surface; in two arbitrary dimensions only, blind white superimposed upon blind dark, it floated toward them. And it was tall, and somehow man-formed, but of no shape that words could describe.

  Smith heard Yarol catch his breath in a gasp behind him. He heard no other sound, though the whiteness floated swiftly forward through the rocky floor. He was sure of that now—a part of it extended farther down than his feet, and they were planted upon solid rock. And though his skin crawled with unreasoning terror, and the hair on his neck prickled with the weird, impossible approach of the impossible thing, he kept his head enough to see that it was apparently solid, yet somehow milkily translucent; that it had form and depth, though no shadows of that darkness lay upon it; that from where no face should have been a blind, eyeless visage fronted him impassively. It was very close now, and though the extremities of it trailed below the floor line, its height lifted far above his head.

  And a nameless, blind force beat out from it and assailed him, a force that somehow seemed to be driving him into unnamable things—an urge to madness, beating at his brain with the reasonless buffeting of insanity, but a wilder, more incomprehensible insanity than the sane mind could understand.

  Something frantic within him clamored for instant, headlong flight—he heard Yarol’s breathing panicky behind him and knew that he too wavered on the verge of bolting—but something insistent at the roots of his brain held him firm before the whiteness bearing down in its aura of madness—something that denied the peril, that hinted at solution …

  Scarcely realizing that he had moved, he found the heat-gun in his hand, and on a sudden impulse jerked his arm up and sent a long, blue-hot streamer of flame straight at the advancing apparition. For the briefest of instants the blue dazzle flashed a light-blade through the dark. It struck the floating whiteness full—vanished—Smith heard a faint crackle of sparks on the invisible floor beyond and knew that it had passed through the creature without meeting resistance. And in that flashing second while the blue gaze split the thickness of the dark he saw it shine luridly upon a splinter of rock in its path, but not upon the white figure. No blaze of blueness affected the deathly pallor of it—he had a sudden conviction that though a galaxy of colored lights were played upon it no faintest hint of color could ever tinge it with any of man’s hues. Fighting the waves of madness that buffeted at his brain, he realized painfully that it must be beyond the reach of men—and therefore—

  He laughed unsteadily and holstered his gun.

  “Come on,” he yelled to Yarol, reaching out blindly to grasp his comrade’s arm, and—suppressing a tingle of terror—plunged straight through that towering horror.

  There was an instant of blaze and blinding whiteness, a moment of turmoil while dizziness swirled round him and the floor rocked under his feet and a maelstrom of mad impulses battered through his brain; then everything was black again and he was plunging recklessly ahead through the dark, dragging a limply acquiescent Yarol behind him.

  After a while of stumbling progress, punctuated with falls, while the white horror dropped away behind them, not following, though the muffling dark still sealed their eyes—the almost forgotten light in Smith’s hand suddenly blazed forth again. In its light he faced Yarol, blinking at the abrupt illumination. The Venusia
n’s face was a mask of question, his black eyes bright with inquiry.

  “What happened? What was it? How did you—how could we—”

  “It can’t have been real,” said Smith with a shaky grin. “I mean, not material in the sense that we know. Looked awful enough, but—well, there were too many things about it that didn’t hitch up. Notice how it seemed to trail through the solid floor? And neither light nor dark affected it—it had no shadows, even in that blackness, and the flash of my gun didn’t even give it a blue tinge. Then I remembered what that little fellow had told us about his three gods: that, though they had real existence, it was on such a widely different plane from ours that they couldn’t touch us except by providing themselves with a material body. I think this thing was like that also: visible, but too other-dimensional to reach us except through sight. And when I saw that the floor didn’t offer any resistance to it I thought that maybe, conversely, it wouldn’t affect us either. And it didn’t. We’re through.”

  Yarol drew a deep breath.

  “The master-mind,” he gibed affectionately. “Wonder if anyone else ever figured that out, or are we the first to get through?”

  “Don’t know. Don’t get the idea it was just a scarecrow, though. I think we moved none too soon. A minute or two longer and—and—I felt as if someone were stirring my brains with a stick. Nothing seemed—right. I think I know now what was wrong with those other two—they waited too long before they ran. Good thing we moved when we did.”

  “But what about that darkness?”

  “I suppose we’ll never really know. Must have had some relation to the other—the white thing, possibly some force or element out of that other dimension; because just as dark couldn’t touch the whiteness of that thing, so light had no effect on the dark. I got the impression, somehow, that the dark space is a fixed area there, as if a section out of the other world has been set down in the cave, for the white thing to roam about it—a barrier of blackness across the way. And I don’t suppose that it can move outside the darkness. But I may be wrong—let’s go!”

  “Right behind you!” said Yarol. “Get along.”

  The cave extended for another fifteen-minute walk, cold and silent and viciously rough underfoot, but no further mishap broke the journey. Tomlinson-lights gleaming, they traversed it, and the glow of cold day at the far end looked like the gleam of paradise after that journey through the heart of the dead rock.

  They looked out upon the ruins of that city where once the gods had dwelt—ragged rock, great splintered teeth of stone upflung, the bare black mountainside folded and tortured into wild shapes of desolation. Here and there, buried in the debris of ages, lay huge six-foot blocks of hewn stone, the only reminder that here had stood Mars’ holiest city, once, very long ago.

  After five minutes of search Smith’s eyes finally located the outline of what might, millions of years ago, have been a street. It led straight away from the slope at the cave-mouth, and the blocks of hewn stone, the crevices and folded ruins of earthquake choked it, but the course it once had run was not entirely obliterated even yet. Palaces and temples must have lined it once. There was no trace of them now save in the blocks of marble lying shattered among the broken stones. Time had erased the city from the face of Mars almost as completely as from the memories of man. Yet the trace of this one street was all they needed now to guide them.

  The going was rough. Once down among the ruins it was difficult to keep in the track, and for almost an hour they clambered over broken rock and jagged spikes of stone, leaping the crevices, skirting great mounds of ruin. Both were scratched and breathless by the time they came to the first landmark they recognized—a black, leaning needle of stone, half buried in fragments of broken marble. Just beyond it lay two blocks of stone, one upon the other, perhaps the only two in the whole vast ruin which still stood as the hands of man had laid them hundreds of centuries ago.

  Smith paused beside them and looked at Yarol, breathing a little heavily from exertion.

  “Here it is,” he said. “The old boy was telling the truth after all.”

  “So far,” amended Yarol dubiously, drawing his heat-gun. “Well, we’ll see.”

  The blue pencil of flame hissed from the gun’s muzzle to splatter along the crack between the stones. Very slowly Yarol traced that line, and in spite of himself excitement quickened within him. Two-thirds of the way along the line the flame suddenly ceased to spatter and bit deep. A blackening hole appeared in the stone. It widened swiftly, and smoke rose, and there came a sound of protesting rock wrenched from its bed of eons as the upper stone slowly ground half around on the lower, tottered a moment and then fell.

  The lower stone was hollow. The two bent over curiously, peering down. A tiny breath of unutterable antiquity rose in their faces out of that darkness, a little breeze from a million years ago. Smith flashed his light-tube downward and saw level stone a dozen feet below. The breeze was stronger now, and dust danced up the shaft from the mysterious depths—dust that had lain there undisturbed for unthinkably long ages.

  “We’ll give it a while to air out,” said Smith, switching off his light. “Must be plenty of ventilation, to judge from that breeze, and the dust will probably blow away before long. We can be rigging up some sort of ladder while we wait.”

  By the time a knotted rope had been prepared and anchored about a near-by needle of rock the little wind was blowing cleanly up the shaft, still laden with that indefinable odor of ages, but breathable. Smith swung over first, lowering himself cautiously until his feet touched the stone. Yarol, when he came down, found him swinging the Tomlinson-beam about a scene of utter lifelessness. A passageway stretched before them, smoothly polished as to walls and ceiling, with curious, unheard-of frescoes limned in dim colors under the glaze. Antiquity hung almost tangibly in the air. The little breeze that brushed past their faces seemed sacrilegiously alive in this tomb of dead dynasties.

  That glazed and patterned passageway led downward into the dark. They followed it dubiously, feet stirring in the dust of a dead race, light-beams violating the million-years night of the underground. Before they had gone very far the circle of light from the shaft disappeared from sight beyond the up-sloping floor behind them, and they walked through antiquity with nothing but the tiny, constant breeze upon their faces to remind them of the world above.

  They walked a very long way. There was no subterfuge about the passage, no attempt to confuse the traveler. No other halls opened from it—it led straight forward and down through the stillness, the dark, the odor of very ancient death. And when at long last they reached the end, they had passed no other corridor-mouth, no other openings at all save the tiny ventilation holes at intervals along the ceiling.

  At the end of that passage a curving wall of rough, unworked stone bulged like the segment of a sphere, closing the corridor. It was a different stone entirely from that under the patterned glaze of the way along which they had come. In the light of their Tomlinson tubes they saw a stone door set flush with the slightly bulging wall that held it. And in the door’s very center a symbol was cut deep and vehement and black against the gray background. Yarol, seeing it, caught his breath.

  “Do you know that sign?” he said softly, his voice reverberating in the stillness of the underground, and echoes whispered behind him down the darkness, “—know that sign… know that sign?“

  “I can guess,” murmured Smith, playing his light on the black outline of it.

  “The symbol of Pharol,” said the Venusian in a near-whisper, but the echoes caught it and rolled back along the passage in diminishing undertones, “—Pharol… Pharol… Pharol!“

  “I saw it once carved in the rock of an asteroid,” whispered Yarol. “Just a bare little fragment of dead stone whirling around and around through space. There was one smooth surface on it, and this same sign was cut there. The Lost Planet must really have existed, NW, and that must have been a part of it once, with the god’s name cut so deep that e
ven the explosion of a world couldn’t wipe it out.”

  Smith drew his gun. “We’ll soon know,” he said. “This will probably fall, so stand back.”

  The blue pencil of heat traced the door’s edges, spattering against the stone as Yarol’s had in the city above. And as before, in its course it encountered the weak place in the molding and the fire bit deep. The door trembled as Smith held the beam steady; it uttered an ominous creaking and began slowly to tilt outward at the top. Smith snapped off his gun and leaped backward, as the great stone slab tottered outward and fell. The mighty crash of it reverberated through the dark, and the concussion of its fall shook the solid floor and flung both men staggering against the wall.

  They reeled to their feet again, shielding blinded eyes from the torrent of radiance that poured forth out of the doorway. It was a rich, golden light, somehow thick, yet clear, and they saw almost immediately, as their eyes became accustomed to the sudden change from darkness, that it was like no light they had ever known before. Tangibly it poured past them down the corridor in hurrying waves that lapped one another and piled up and flowed as a gas might have done. It was light which had an unnamable body to it, a physical, palpable body which yet did not affect the air they breathed.

  They walked forward into a sea of radiance, and that curious light actually eddied about their feet, rippling away from the forward motion of their bodies as water might have done. Widening circles spread away through the air as they advanced, breaking soundlessly against the wall, and behind them a trail of bright streaks streamed away like the wake of a ship in water.

  Through the deeps of that rippling light they walked a passage hewn from ragged stone, a different stone from that of the outer corridor, and somehow older. Tiny speckles of brightness glinted now and again on the rough walls, and neither could remember ever having seen just such mottled, bright-flecked rock before.
