She turned uncertainly and staggered a step back along the way they had come. Smith sprang forward and slid his free arm about her, but she shuddered away from the contact.

"No, no-unbearable-the touch of clean human flesh-and it breaks the chord of my remembering. . . .

I can not look back into his mind as it was when I dwelt there, and I must, I must. . . ."

She shook him off and reeled on, and he cast one last look at the billowing sea, and then followed. She staggered along the stone floor on stumbling feet, one hand to the wall to support herself, and her voice was whispering gustily, so that he had to follow close to hear, and then almost wished he had not heard, "-black slime-darkness feeding on light-everything wavers so- slime, slime and a rolling sea-he rose out of it, you know, before civi-lization began here-he is age-old-there never has been but one Alen-dar. . . . And somehow-I could not see just how, or remember why-he rose from the rest, as some of his race on other planets had done, and took the man-form and stocked his breeding-pens. . . ."

They went on up the dark hallway, past curtains hiding incarnate loveliness, and the girl's stumbling footsteps kept time to her stumbling, half-incoherent words.

"-has lived all these ages here, breeding and devouring beauty- vampire-thirst, a hideous delight in drinking in that beauty-force-I felt it and remembered it when I was one with him-wrapping black layers of primal slime about-quenching human loveliness in ooze, sucking-blind black thirst. . . . And his wisdom was ancient and dreadful and full of power-so he could draw a soul out through the eyes and sink it in h.e.l.l, and drown it there, as he would have done mine if I had not had, somehow, a difference from the rest. Great Shar, I wish I had not! I wish I were drowned in it and did not feel in every atom of me the horrible uncleanness of-what I know. But by virtue of that hidden strength I did not surrender wholly, and when he had turned his power to subduing you I was able to struggle, there in the very heart of his mind, making a disturbance that shook him as he fought us both-making it possible to free you long enough for you to destroy the human flesh he was clothed in-so that he lapsed into the ooze again. I do not quite understand why that happened-only that his weakness, with you a.s.sailing him from without and me struggling strongly in the very center of his soul was such that he was forced to draw on the power he had built up to maintain himself in the man-form, and weakened it enough so that he collapsed when the man-form was a.s.sailed. And he fell back into the slime again-whence he rose-black slime-heaving-oozing. . - ."

Her voice trailed away in murmurs, and she stumbled, all but fall-ing. When she regained her balance she went on ahead of him at a greater distance, as if his very nearness were repugnant to her, and the soft babble of her voice drifted back in broken phrases without meaning.

Presently the air began to tingle again, and they pa.s.sed the silver gate and entered that gallery where the air sparkled like champagne. The blue pool lay jewel-clear in its golden setting. Of the girls there was no sign.

When they reached the head of the gallery the girl paused, turning to him a face twisted with the effort at memory.

"Here is the trial," she said urgently. "If I can remember-" She seized her head in clutching hands, shaking it savagely. "I haven't the strength, now-can't-can't-" the piteous little murmur reached his ears incoherently. Then she straightened resolutely, swaying a little, and faced him, holding out her hands.

He clasped them hesitantly, and saw a shiver go through her at the contact, and her face contort painfully, and then a shudder communicated itself through that clasp and he too winced in revolt. He saw her eyes go blank and her face strain in lines of tensity, and a fine dew broke out on her forehead. For a long moment she stood so, her face like death, and strong shudders went over her body and her eyes were blank as the void be-tween the planets.

And as each shudder swept her it went unbroken through the clasp-ing of their hands to him, and they were black waves of dreadfulness, and again he saw the heaving sea and wallowed in the h.e.l.l he had fought out of on the gallery, and he knew for the first time what tor-ture she must be enduring who dwelt in the very deeps of that uneasy dark. The pulses came faster, and for moments together he went down into the blind blackness and the slime, and felt the first wriggling of the worm-thoughts tickling the roots of his brain.

And then suddenly a clean darkness closed round them and again everything shifted unaccountably, as if the atoms of the gallery were changing, and when Smith opened his eyes he was standing once more in the dark, slanting corridor with the smell of salt and antiquity heavy in the air.

Vaudir moaned softly beside him, and he turned to see her reeling against the wall and trembling so from head to foot that he looked to see her fall the next moment. - "Better-in a moment," she gasped. "It took-nearly all my strength to-to get us through-wait. . - ."So they halted there in the darkness and the dead salt air, until the trembling abated a little and she said, "Come," in her little whimper-ing voice. And again the journey began. It was only a short way, now, to the barrier of black blankness that guarded the door into the room where they had first seen the Alendar.

When they reached the place she shivered a little and paused, then resolutely held out her hands. And as he took them he felt once more the hideous slimy waves course through him, and plunged again into the heaving h.e.l.l. And as before the clean darkness flashed over them in a breath, and then she dropped his hands and they were standing in the archway looking into the velvet-hung room they had left-it seemed eons ago.

He watched as waves of blinding weakness flooded over her from that supreme effort. Death was visible in her face as she turned to him at last.

"Come-oh, come quickly," she whispered, and staggered forward.

At her heels he followed, across the room, past the great iron gate-way, down the hail to the foot of the silver stairs. And here his heart sank, for he felt sure she could never climb the long spiral distances to the top. But she set her foot on the step and went upward resolutely, and as he followed he heard her murmuring to herself, "Wait-oh, wait-let me reach the end-let me undo this much- and then-no, no! Please Shar, not the black slime again. - . . Earth-man, Earthman!"

She paused on the stair and turned to face him, and her haggard face was frantic with desperation and despair.

"Earthman, promise-do not let me die like this! When we reach the end, ray me! Burn me clean, or I shall go down for eternity into the black sinks from which I dragged you free. Oh, promise!"

"I will," Smith's voice said quietly. "I will."

And they went on. Endlessly the stairs spiraled upward and end-lessly they climbed. Smith's legs began to ache intolerably, and his heart was pounding like a wild thing, but Vaudir seemed not to no-tice weariness. She climbed steadily and no more unsurely than she had come along the halls. And after eternities they reached the top.

And there the girl fell. She dropped like a dead woman at the head of the silver spiral. Smith thought for a sick instant that he had failed her and let her die uncleansed, but in a moment or two she stirred and lifted her head and very slowly dragged herself to her feet.

"I will go on-I will, I will," she whispered to herself. "-come this far-must finish-" and she reeled off down the lovely, rosily-lit hall-way paneled in pearl.

He could see how perilously near she was to her strength's end, and he marveled at the tenacity with which she clung to life though it ebbed away with every breath and the pulse of darkness flowed in after it. So with bulldog stubbornness she made her wavering way past door after door of carven sh.e.l.l, under rosy lights that flushed her face with a ghastly mockery of health, until they reached the silver gate-way at the end. The lock had been removed from it by now, and the bar drawn.

She tugged open the gate and stumbled through.

And the nightmare journey went on. It must be very near morning, Smith thought, for the halls were deserted, but did he not sense a breath of danger in the still air?.

The girl's gasping voice answered that half-formed query as if, like the Alendar, she held the secret of reading men's minds.

"The-Guardians-still rove the halls, and unleashed now-so keep your ray-gun ready, Earthman. . . ."

After that he kept his eyes alert as they retraced, stumbling and slow, the steps he had taken on his way in. And once he heard dis-tinctly the soft slither of-something-sc.r.a.ping over the marble pave-ment, and twice he smelt with shocking suddenness in this scented air a whiff of salt, and his mind flashed back to a rolling black sea.

- . . But nothing molested them.

Step by faltering step the hallways fell behind them, and he began to recognize landmarks, and the girl'sfootsteps staggered and hesi-tated and went on gallantly, incredibly, beating back oblivion, fighting the dark surges rolling over her, clinging with tenacious fingers to the tiny spark of life that drove her on.

And at long last, after what seemed hours of desperate effort, they reached the blue-lit hallway at whose end the outer door opened. Vaudir's progress down it was a series of dizzy staggers, interspersed with pauses while she hung to the carven doors with tense fingers and drove her teeth into a bloodless lip and gripped that last flicker of life. He saw the shudders sweep over her, and knew what waves of washing dark must be rising all about her, and how the worm-thoughts writhed through her brain. - . . But she went on. Every step now was a little tripping, as if she fell from one foot to the other, and at each step he expected that knee to give way and pitch her down into the black deeps that yawned for her. But she went on. - She reached the bronze door, and with a last spurt of effort she lifted the bar and swung it open. Then that tiny spark flickered out like a lamp. Smith caught one flash of the rock room within-and something horrible on the floor-before he saw her pitch forward as the rising tide of slimy oblivion closed at last over her head. She was dying as she fell, and he whipped the ray-gun up and felt the recoil against his palm as a blue blaze flashed forth and transfixed her in midair. And he could have sworn her eyes lighted for a flickering in-stant and the gallant girl he had known looked forth, cleansed and whole, before death-clean death-glazed them.

She slumped down in a huddle at his feet, and he felt a sting of tears beneath his eyelids as he looked down on her, a huddle of white and bronze on the rug. And as he watched, a film of defilement veiled the shining whiteness of her-decay set in before his eyes and progressed with horrible swiftness, and in less time than it takes to tell he was staring with horrified eyes at a pool of black slime across which green velvet lay bedraggled.

Northwest Smith closed his pale eyes, and for a moment struggled with memory, striving to wrest from it the long-forgotten words of a prayer learned a score of years ago on another planet. Then he stepped over the pitiful, horrible heap on the carpet and went on.

In the little rock room of the outer wall he saw what he had glimpsed when Vaudir opened the door.

Retribution had overtaken the eunuch. The body must have been his, for tatters of scarlet velvet lay about the floor, but there was no way to recognize what its original form had been. The smell of salt was heavy in the air, and a trail of black slime snaked across the floor toward the wall. The wall was solid, but it ended there. . .

Smith laid his hand on the outer door, drew the bar, swung it open. He stepped out under the hanging vines and filled his lungs with pure air, free, clear, untainted with scent or salt. A pearly dawn was break-ing over Ednes.

The Bright Illusion

Through the blinding shimmer of sun upon sand, Dixon squinted painfully at the curious mirage ahead. He was reeling with thirst and heat and weariness, and about him the desert heaved in long, blurred waves, but through the haze of his own weakness, and through the sun haze upon the desert, he peered anxiously at the thing and could not make it out.

Nothing he had ever seen or heard of could cause such a mirage as this. It was a great oval of yellow light, bulging up convexly from the earth like some translucent golden egg half buried in the sand. And over its surface there seemed to be an immense busyness, as if it was covered with tiny, shimmering things that moved constantly. He had never seen anything remotely resembling it before.

As he toiled through the sand toward the bright illusion, he became aware of darker specks around it haphazardly, specks that as he approached took on the aspect of men grotesquely sprawled in atti-tudes of death. He could not make it out. Of course it was a mirage, yet it did not recede as he advanced, and the details of those sprawled bodies became clearer and clearer, and the great translucent oval loomed up against the sky mystifyingly.

He thought he must be dreaming, or perhaps a little unbalanced by the heat and thirst. He had been struggling through this burning sand under this burning sun for a long while now, and there were timeswhen the rush of illusion swallowed him up, and he could hear water splashing and fountains tinkling in the empty desert about him. This must be a hallucination, then, for it could scarcely be a mirage. He was almost upon it, and it had so real a look-those bodies, sprawl-ing- He stumbled over the first, for somehow his muscles did not co-or-dinate very well now. It was the sun-withered body of an old man in the Legion uniform, his kepi fallen forward over his face. The next was that of an Arab in a tangle of dirty white garments, and beyond him was the almost-fresh corpse of a boy in khaki shorts and sun helmet.

Dixon wondered duly what had happened to them and why the bodies were in such varying stages of decomposition. He lifted a drag-ging head and peered at the great egg-shape thing bulging up from the sand. It reminded him of a huge bubble of golden water, save that bubbles were round, and- Belatedly, caution returned to him. These dead men must have met their deaths somehow through the presence of the great egg. He had better advance more cautiously or- And then the pull seized him. He had come too near. Something inexorable and slow was dragging him forward-or was it that the great bubble was advancing toward him?

Sky and sand reeled. And the distance between him and the great egg-shaped thing lessened and lessened and-and somehow he found himself flat against a great golden translucency that shivered against him with the strangest motion, as if it was alive and hungry for- He felt that he should be afraid, yet somehow he was not aware of fear at all. The golden light was closing over him and around him with a queer, engulfing motion. He shut his eyes and relaxed utterly in the impa.s.sive grip of the thing.

Dixon was lying motionless in the midst of a golden radiance that seemed crystal clear, yet so obstructed his vision that he could see only a few yards away, and the desert landscape outside was as unreal as a dream. The most delicious sensation of rest and well-being was surg-ing through him in slow waves that succeeded one another like rip-ples on a sh.o.r.e, each leaving an increasing residue of serenity and luxurious comfort. Thirst and hunger and weariness had vanished in a breath. He knew no fear or anxiety.

In a trancelike calm he lay there, feeling the waves flow through him unbroken, staring up into the lucid golden light without wonder or surprise.

How long he lay there he never knew. In the perfect peace of the glow enfolding him, he was very dimly aware that the all-penetrating waves were washing through him in a way which queerly suggested searching. They permeated every atom of him, flooding his brain with light and calmness.

In his tranced quiet he knew, without actually realizing, that mem-ory in lightning flashes was reeling through his mind. Abstract memo-ries of things he had learned in college and in afterlife. s.n.a.t.c.hes of lit-erature, fragments of sciences. Mathematical problems solved in breathtaking speed and supplanted by chemical formulas that melted into the bits of psychology remembered from schooldays. Impa.s.sively he lay there, scarcely realizing the flashing reviews that pa.s.sed through his light-flooded brain.

And then the tempo of the ripples that went over him began to change. His mind awoke by degrees from its pleasant coma, though his body still lay relaxed. And now the wavelets in the queerest way were beating upon his brain tantalizingly. Little fragments of thoughts not his own blew through his mind and faded.

He struggled to grasp them. He clutched at the vanishing tags, striv-ing to weld them together, feeling obscurely that if he could retain each small flutter as it wavered through his mind, if he could put them together and fuse them in a unit, he might understand.

Very slowly he succeeded. Very slowly the waves as they flowed through him began to surrender their meanings to his clutching mind: meanings that solidified and amplified with each succeeding wave, building themselves up slowly as ripple after ripple washed serenely through the straining brain that was learning so painfully to comprehend their significance.

By degrees Dixon realized that some intelligence was striving to communicate with him. The knowledge did not come in words or even word forms introduced into his brain. But it came, slowly and inexorably, building up and up as wave after measured wave flowed through him and vanished, leaving a residue of knowledge to be increased by the next.

And the vast, the almost divine, impersonality of it staggered him. This being-intelligence,presence-was so utterly abstract a thing that even in the knowledge it imparted to him there was no hint of personality or consciousness of individual being. There could have been no "I" in its supervocabulary of thought ripples. Divinely serene, divinely abstract, it allowed knowledge to flow through the brain of the man suspended in its heart. And by measured degrees that knowl-edge built itself up in his mind.

He had been chosen. For a long while this being had been waiting here, trapping the men who came near enough, sending its light waves in floods through their minds to illuminate their thoughts and their capacity for knowledge, probing their intelligences. All those others. lying outside had been found wanting. The being had discarded them and waited, in its serene pa.s.sivity, until the right man came by.

This much flowed through his brain. Then there was a hiatus, to permit him to absorb the knowledge, to understand. After a while the wavelets began to beat through him again in their measured slowness. He became aware of vast, dim voids, blank stretches empty of s.p.a.ce or time or any of the myriad dimensions. He knew that through these, while long periods elapsed which yet had no relation to the time he understood, the great light-bubble had traveled from some origin un-thinkably far away, on a quest. He realized that it had at last emerged from those gray, formless voids into the interstellar s.p.a.ce of his own universe; that it had made its way here, driven by a vast purpose he could not grasp, and had come to rest upon the desert sands, to lie in wait.

Again there was a gap in the thought waves, and again Dixon lay still, a.s.similating that stunning knowledge. And yet, somehow, he was not greatly surprised or in the remotest way skeptical. He waited.

Presently the flow began again. There was, in another part of s.p.a.ce, a world which this being desired-or no, not desired; there was noth-ing so human or personal a thing as desire about it. A world which it meant to have; a very alien world, he gathered, from the sort he knew. Peopled by alien creatures and built in other dimensions than those which formed his own universe.

These people worshiped a powerful G.o.d. And it was this worship- this G.o.dhood-which the being that enfolded him meant to possess. It tried to give him a glimpse of why, but the thought waves which flowed through his brain were incomprehensible and remote-not knowledge, but a jumble of unrelated impressions, without coherence. After a few vain attempts to instill the reason for its purpose into his mind, the being apparently dismissed the point as unnecessary and went on.

This G.o.d which it meant to dispossess was very powerful; so power-ful that of itself the being could do nothing to overthrow it, could not even pa.s.s the barriers set up to guard the strange world. It had need of an intelligent, animate creature from a world different enough in structure so that the G.o.d's peculiar powers would have no effect upon him.

Gradually the measured beats made it clear to Dixon that he was the chosen envoy. He was to be transported there, armed in potent ways, sent out into the new world to overthrow the G.o.d's domain and make way for his sponsor to take possession.

There was a long hiatus after that. Dixon lay quiet, rather stunned by the magnitude of the thing. The being which engulfed him must have sensed the growing rebellion in his mind, for after a while the beats began again. And Dixon knew that the proposition was not a compulsory one. But-the knowledge flowed casually through him- though he was free to be released and set back upon his journey if he refused the plan, he would inevitably die soon, die very unpleasantly.

There was no water within any possible reach, and a band of veiled Tuaregs was scouring the desert nearby in search of that Arab who lay in a huddle of dirty white robes outside the egg-shaped bubble. If he did not die of thirst before they caught him, he would die in a manner infinitely more undesirable at their hands. But, of course, if he so desired, he was free to go.

Dixon digested this information thoughtfully, hesitatingly, though he knew he had no choice. His blind stumbling through the desert could have no other end than slow death, as he had been aware even before he came upon the great bubble. And if there were Tuaregs near-Even in the bodily trance that cradled him he shud-dered. He had seen victims of Tuareg tortures, miraculously alive after days and days of-He turned his mind from that. No; he had no choice.

And gradually a little spark of excitement began to burn in him. What an adventure! And though death might lie at the end of it, there was ~t least a hope for life, and he knew he had not even that if he refused.Consent was forming in his mind, but, even before it crys-tallized, the being must have known, for about him the lucid radiance suddenly began to cloud and change. Milkiness flooded through it and through his body and his brain. Oblivion swallowed him up.

When realization returned to Dixon it came slowly. Layer by layer the oblivion melted from his mind. He had a vague impression of vast s.p.a.ces traversed and barriers surmounted, and somehow he sensed an indefinable difference in the s.p.a.ce that surrounded the bubble, though it was indefinite how he knew it. A little beat quivered through him, and another, clearing away the fogs of his conscious-ness. Then knowledge began to pulse again through him in measured flow.

They had crossed gulfs greater than he could comprehend. They were suspended now above the world of their destination. He was to look briefly upon it, for even through the protecting walls of the light-bubble the thing that he would see was so alien to him that in his present form he could not bear to gaze upon it long.

Then the light about Dixon cleared to translucence, and somehow he was looking out and down upon a scene that stunned his eyes with its violence. He had an instant's impression of a land that shrieked and raved with maniacal color beyond any conception of color as he knew it. He turned his eyes wincingly away and stared down at the scene immediately below. And though in point of actual s.p.a.ce it must have been very far away, he could see everything quite clearly and with a wider radius of vision than he was accustomed to. It was as if in one glance he encompa.s.sed the whole circle of the horizon.

The world below was one vast city that reeled away in terrace below crazy terrace out to a skyline that shimmered with white dazzle. And the colors that blazed and howled and agonized over the insane an-gles of the place turned him sick and dizzy. They were incredible angles and impossible colors, the tints and the tilts of madness- wild, staggering lines and arcs and jagged peaks, crazy inclines broken by ridges of eruptive color, zigzag bridges, buildings that leaned out in gravity-defying angles.

All these incredible terraces mounted up and up in diminishing arcs to the topmost tier of all. This was small and smooth, though over its pavement the insane colors sprawled blotchily. And in the very center a mighty column rose, blacker than any darkness he had ever seen before. On its height burned a pale flame.

But the inhabitants! Dixon could see them quite clearly despite the distance. They were sinuous and serpentine, and their motions were blurs of swiftness, poems of infinite grace. They were not men-they had never been men in any stage of their evolution. And if the colors of the buildings were agony to his eyes, the living, unstable hues that writhed and crawled over the beings below were so frightful that his gaze rebelled. For this reason he never knew just how they were shaped.

There was one standing just below the great black pillar whereon burned the flame, and of this he had the clearest view. It was boneless and writhing, livid with creeping color. Its single great eye, lucid and expressionless, stared from an unfeatured, mouthless face, half scarlet and half purple, between which two shades a wedge of nameless green broadened as he looked away.

He had seen this much before the pellucid crystal began to cloud about him once more and the slow knowledge began its beat through his brain. He must look no longer, or something disastrous might hap-pen to his benumbed senses. He understood by now that it was not in his own form that he was to go out into the crazy land. He was sure, even without that seeping knowledge, that his own body could never endure the colors of the place, nor could his own material feet tread the dizzy angles. Many of the streets and bridges were too steep for human feet to walk.

And he was understanding, as the slow waves flowed on, how different these people were from his own kind. Not only in appear-ance; their very substance was different from flesh and blood, the atoms arranged in different patterns. They obtained nourishment in an incomprehensible way from some source he could not understand. Their emotions and habits and purposes were alien to all his experi-ence, and among them even the s.e.xes were not those he knew.

They were more numerous than mankind's two, and their functions were entirely different. Reproductionhere was based on an utterly alien principle.

When the pause came in the waves of knowledge, Dixon was a lit-tle dizzy with the complete strangeness of this place and with wonder how he would be enabled to enter it. He lay still, wondering, until the flow began again.

Then the knowledge of the way he was to be introduced into the strange G.o.d's domain began to surge in deliberate beats through his brain. It seemed simple, yet the magnitude of it was staggering. A sort of veil of illusion was to be dropped between him and these alien beings. To them, his form would seem one of their own. Through the veil his speech would be filtered and changed into their indescribable mode of communication. And to him they would have the appear-ance of humanity, their speech would be understandable, their curious emotions translated into familiarity.

Even their multiple s.e.xes would be resolved arbitrarily into two. For though this being could not approach any nearer the strange G.o.d whose flame burned upon the pillar, it seemed to have immense power even from this distance in the crazy world below..

The slow-beating waves made him aware that during his sojourn in the strange place he would be guided and in a measure protected, and that this knowledge would still flow through his brain. All this was possible, he understood, because of his own complete difference from anything in this world-such a difference that he would not cause even a ripple upon the surface of the G.o.d's consciousness until the time came for his overthrow.

Then again the cloudiness began to clear, until Dixon was looking out through crystal walls upon that reeling city below. For an instant it shuddered with mad colors before his aching eyes. And then over the whole crazy panorama the queerest blurring came. He looked down upon a changing world wherein the wild colors faded and ran together and the staggering angles of that mighty vista below were obscured in structural changes whose purpose he began to under-stand.

Before his eyes a splendid and stately city was taking shape. Out of the ruin of eye-wrenching color rose tier beyond tier of white pillars and translucent domes. Roofs of alabaster formed themselves under a sky whose pallor was deepening into blue.

When he tore his eyes away from that magnificent vista, terrace dropping away below terrace, crowned with domes and spires and col-umns wreathed in green, far out to the distant horizon, he saw that over the crowded streets with their swarms of multicolored horrors a stranger change was falling. Out of the mingling indistinctnesses of those colors without name, the semblance of humanity grew. People of n.o.ble stature and stately bearing, robed in garments of shining steel, took form before his eyes.

In less time than it takes to tell, a metropolis of familiar aspect stretched invitingly under his gaze. That nightmare of colors was gone as a nightmare goes, leaving no faintest trace behind. Yet he knew as he looked down that in reality nothing was changed. The writhing people still flashed with infinite speed and grace through tiptilted streets of gravity-defying angles. He blinked and looked again, but the illusion held steady-a stupendous city, smiling under a blue, familiar sky.

Slowly through his consciousness beat the realization that, once down there in the metamorphosed world, he must search out the tem-ple of the G.o.d, find its vulnerable spot, provide as it were a window, so that through his eyes the being which had brought him here could see its enemy's weakness and instruct Dixon further. And it was impressed upon him, too, that all possible speed must be made, for though there was little danger that the G.o.d would realize the inimical presence, yet his very safeguard was his greatest danger. Dixon was so alien to the ultimate particles of his being that, though this protected him from the G.o.d, it made his maintenance in the strange world very difficult. It was a strain even upon the vast powers of the light-bubble being to keep that veil of illusion stretched protectingly between him and this world, the very sight and touch of which would send him mad if he was exposed to it long unguarded.

There was a little pause after this, and Dixon lay still, awed by the unthinkable difference between his own structure of mind and body and that of the strange place and people below. Then with breath-taking abruptness, darkness dropped over him. One instant he lay serenely cradled in golden radiance, the next he was dropping through blackness with a queer, high scream in his ears as if he fell through some resisting atmosphere which was not air. Physically he was pro-tected, but he could hear the thin sound of it in varying intensities.And then without warning the darkness broke, and he found his feet upon solid ground without any hint of jar. He was simply stand-ing upon a marble pavement under a clear blue sky and looking out over a breath-stopping vista of world-city, dropping away in terrace below shining terrace to a distant skyline, out and away in broadening tiers. Light shimmered dazzlingly upon faraway steel figures moving through the streets below, away and away until they were no more than tiny pinp.r.i.c.ks of shimmer on the horizon's edge. From each broad circular terrace a marble ramp led down to the next beneath, and over these the steel-bright people were swarming in busy hordes.

And Dixon knew, even as he stared with caught breath at the magnificence of it, that in reality he stood at the apex of a city of madness that reeled away below him in tier after crazy tier, a night-mare of meaningless angles and raving color, through whose streets things writhing and dreadful and acrawl with living hues were flashing with movements of blurring speed. All this splendor was a veil across his eyes.

What unknowable activities were really taking place below? On what nameless errands were these busy crowds bound? Then a lit-tle sound at his side turned him from the dizzy thoughts tormenting his brain, and he flashed an abrupt glance sidewise, alert for danger. Then he caught his breath and stared.

She was slim as a sword blade in her steel robe, standing under the mighty tower of the black pillar, and she was lovelier than a dream. Her hair swung in black page-boy curls to her shoulders, and from under the darkness of it eyes as blue as steel met his unwaveringly. She was all bright metal to his first glance, steel-molded curves of her under the armored robe, steel lights upon her b.u.mished hair, steel-bright eyes shining. All steel and brightness-but Dixon saw that her mouth was soft and colored like hot embers.

And for an instant he wanted to burst into crazy song. It was an inexplicable feeling that he had never known before, a heady delight in being alive. But even through the exultation, he knew that he looked upon an illusion. He knew that she was a faceless, crawling thing, without s.e.x, without any remotest kinship to anything he knew. And yet this illusion was very lovely and- She was looking up at him with startled eyes, and now she spoke, a little breathlessly, in a sweet, tinkling voice. "You-you have come? Oh, whence have you come?" And he thought that she was striving hard not to believe something which she wanted with all her soul to think true.

There was no answer he could give. He glanced around helplessly at the blue, empty sky, at the great pillar rising behind her, at the pale flame burning so steadily upon its summit. The blaze held him for an instant, and in the instant he stood with eyes uplifted the girl must have thought she had her answer, for she caught her breath in a gasp that was half a sob, and in one swift motion she fell to her knees before him, a miracle of sliding grace in that close gown of steel, so that the light rippled all down her sweet, slim body and lay bluely on the wings of her hair that swung forward as she bent her head.

"I knew it! I knew!" she breathed. "I knew my G.o.d would send you! Oh, praise great IL, who has sent me such an envoy!"

Dixon looked down upon the bent black head, his eyes troubled. If she believed him a messenger from the G.o.d, it would simplify his task enormously. And yet . . . He had entertained no scruples about displacing the G.o.d of a maniacal world peopled with writhing mon-strosities, but this was different, somehow. This girl.

"I am the high priestess of our G.o.d," she murmured, as if in answer to his half-formed query. "I have served IL with all my heart for many cycles now, but only he knows how I have prayed for the coming of an envoy among us. Such honor is enough to-to-" The sweet voice choked suddenly on a sob, as if the answer to her prayer was too much for her to endure unmoved.

Dixon bent and took her chin in his hand, lifting her face to his. The steel-bright eyes were dazzling with diffused tears. The red mouth trembled. She was looking up at him with awe and worship upon her face, and suddenly he knew that he wanted no worship from her. He resented that look of respect and awe.

He wanted-well, he wanted her to see a man, not a divine messenger. He wanted to- Then the queerest madness came over him, deliciously-and he acted. He stooped swiftly and set his lips over the trembling red lips of the girl, and for an instant the whole strange world reeled and swam in a heady pleasure like nothing he had ever known before.

When he straightened and stood looking down upon her, she met his eyes with purest bewilderment inhers, one hand hovering at her lips and incomprehension radiant in every line of her. Her blue gaze was traveling over him from head to foot in swift, puzzled glances.

And then realization swept back upon him tremendously. To her he wore the writhing shape that was hers in reality. That troubled blue gaze was the gaze of a single pale eye which traveled over the crawling limbs of a monster. He was not even sure that, to her, kneeling denoted homage and wondered in what alien way she was ac-tually expressing her awe.
