“ Why—he asked himself in a determined groping after steadiness—should the mere sight of a tree, even so fabulous a one as this, rouse that insane panic in the gazer? What peril could dwell invisibly in a tree so frightful that the living horror of it could drive a man mad with the very fact of its unseen presence? He clenched his teeth hard and stared resolutely at that terrible beauty in the clearing, fighting down the sick panic that rose in his throat as his eyes forced themselves to dwell upon the Tree.
Gradually the revulsion subsided. ”

“ Well, here was Earth beneath him. No longer a green star high in alien skies, but warm soil, new clover so near his face he could see all the little stems and trefoil leaves, moist earth granular at their roots. An ant ran by with waving antennae close beside his cheek. He closed his eyes and drew another deep breath. Better not even look; better to lie here like an animal, absorbing the sun and the feel of Earth blindly, wordlessly.
Now he was not Northwest Smith, scarred outlaw of the spaceways. ”

“ Struggling in the tight, hot coils, breathing the nameless essence of horror, Smith fought to free his hand.
The music that had rung so long in his ears was changing as the branches lifted him higher, losing its melody and merging by swift degrees into a hum of vast and vibrant power that deepened in intensity as the limbs drew him upward into Thag's monstrous bulk, the singing force of a thing mightier than any dynamo ever built. Blinded and dazed by the force thundering through every atom of his body, he twisted his hand in one last, convulsive effort, and fired. ”

“ Something of their panic had communicated itself to him, and he advanced with a sinking at the pit of his stomach. Fear of the unknown is so poignant a thing, feeding on its own terror, that he found his hands beginning to shake a little and his throat going dry as he went on.
The rustling and whispering among the bushes dwindled as his followers one by one dropped away, the bravest staying the longest, but even they failing in courage as Smith advanced steadily in that direction from which all their lives they had been taught to turn their faces. ”

“ Then with a tiger's leap they darted, and the victim was swept out of the priestess' guiding hands up into the branches that darted round like tangled snakes in a clot that hid him for an instant from view. Smith heard a high, shuddering wail ripple out from that knot of struggling branches, a dreadful cry that held such an infinity of purest horror and understanding that he could not but believe that Thag's victims in the moment of their doom must learn the secret of his horror. ”

“ Truly a more than human agency must have arched these subtle curves so delicately into dreadfulness, into such an awful beauty that the very sight of it made those atavistic terrors he was so sternly holding down leap in a gibbering terror.
A tremor rippled over the Tree. Smith froze rigid, staring with startled eyes. No breath of wind had stirred through the clearing, but the Tree was moving with a slow, serpentine grace, writhing its branches leisurely in a horrible travesty of voluptuous enjoyment. ”

“ The writhing branches struck downward, straight for his face. And in one flashing leap the moment's infinite horror galvanized him out of his paralysis. Why, he could not have said. It is not given to many men to know the ultimate essentials of all horror, concentrated into one fundamental unit. To most men it would have had that same paralyzing effect up to the very instant of destruction. But in Smith there must have been a bed-rock of subtle violence, an unyielding, inflexible vehemence upon which the structure of his whole life was reared. Few men have it. ”

“ The sound grew sweeter as it strengthened, with a queer, inexplicable sweetness unlike any music he had ever heard before, rounder and fuller and more complete than any melody made up of separate notes. Stronger and stronger he felt the certainty that it was the song of some mighty power, humming and throbbing and deepening through the twilight until the whole dim land was one trembling reservoir of sound that filled his entire consciousness with its throbbing, driving out all other thoughts and realizations, until he was no more than a shell that vibrated in answer to the calling. ”

“ Northwest Smith is one of the great adventurers of Science Fiction, one of that group of cool, gray-eyed men who roam the spaceways and provide much of the inspiration for the legends that are a part of the folklore of space. ”

“ The tree-folk had forgotten even their inbred fear at Thag's calling, and walked boldly through the open twilight, lost in the wonder of the song.
Smith went on with the rest, deaf and blind to the land around him, alive to one thing only, that summons from the siren tune. Unrealizingly, he retraced the course of his frenzied flight, past the trees and bushes he had blundered through, down the slope that led to the Tree's hollow, through the thinning of the underbrush to the very edge of the last line of foliage which marked the valley's rim. ”

“ If he were the boy again knowing all he knew today, still the flaw would be there and sooner or later the same thing must have happened that had happened twenty years ago. He had been born for a wilder age, when men took what they wanted and held what they could without respect for law. ”

“ A gripping tale of the planet Mars and the terrible monstrosity that called its victims to it from afar—a tale of Northwest Smith
Over time-ruined Illar the searching planes swooped and circled. Northwest Smith, peering up at them with a steel-pale stare from the shelter of a half-collapsed temple, thought of vultures wheeling above carrion. All day long now they had been raking these ruins for him. Presently, he knew, thirst would begin to parch his throat and hunger to gnaw at him. ”

“ In the sun the shadow tracery of the grille's symbolic pattern lay vividly outlined on the ground. The girl gave a little gasp of delight. She dropped his hand and ran forward three short steps, and plunged into the very center of that shadowy pattern on the ground. And what happened then was too incredible to believe.
The pattern ran over her like a garment, curving to the curve of her body in the way all shadows do. But as she stood there striped and laced with the darkness of it, there came a queer shifting in the lines of black tracery, a subtle, inexplicable movement to one side. ”

“ Now she was under the Tree, and its trunk had writhed down over her and she was lifting her arms like a girl to her lover. With a gliding slowness the flame-tipped branches slid round her. In that incredible embrace she stood immobile for a long moment, the Tree arching down with all its curling limbs, the girl straining upward, her head thrown back and the mantle of her hair swinging free of her body as she lifted her face to the quivering blossoms. ”

“ Thag must be fed. It is we who—feed—him, but there are times when he desires other food than us. It is then he sends his priestess forth to lure—food—in. Oh, beware of Thag!"
"You mean then, that she—the priestess—brought me in for—food?"
A chorus of grave, murmuring affirmatives.
"Then why did she leave me?"
"There is no escape from Thag. Thag is the center of creation. All things are Thag's. When he calls, you must answer. When he hungers, he will have you. Beware of Thag!"
Smith considered that for a moment in silence. ”

“ The reeling of millenniums set Smith's mind awhirl with the effort at compassing their span.
There was another connotation in the speaking of that tongue by these timid bush-dwellers, too. It must mean that the forgotten wizard king, Illar, had peopled his sinister, twilight land with the ancestors of today's dryland dwellers. If they shared the same tongue they must share the same lineage. And humanity's remorseless adaptability had done the rest. ”

“ But even as they rose, Smith was twisting in their clutch to maneuver his hand into a position from which he could blast that undulant tree trunk into nothingness. He knew intuitively the futility of firing up into Thag's imponderable mass. Thag was not of the world he knew; the flame blast might well be harmless to that mighty hoverer in the twilight. But at the Tree's root, where Thag's essential being merged from the imponderable to the material, rooting in earthly soil, he should be vulnerable if he were vulnerable at all. ”

“ Caught in a timeless paralysis of horror, Smith stared upward into the enormous bulk of Thag while the music hummed intolerably in his shrinking brain—Thag, the monstrous thing from darkness, called up by Illar in those long-forgotten times when Mars was a green planet. ”

“ It was a woman. Or it had the dim outlines of a woman, huddled against an angle of fallen walls and veiled in a fabulous shower of long dark hair. But there was something uncannily odd about her. He could not focus his pale stare upon her outlines. She was scarcely more than a luminous blot of whiteness in the gloom, shimmering with a look of unreality which the sound of her sobs denied. ”

“ He was surer of this when they began to grow bolder as he went down into the dimness of the place. The whispers shrilled a little, and the boldest among his watchers ran almost at his elbow, twittering their queer, broken speech in hushed syllables whose familiarity still bothered him with its haunting echo of words he knew. When he had reached the center of the hollow he became aware that the little folk had spread out in a ring to surround him. ”

“ Thag might not be the center of the universe, but if they said he could call a victim from anywhere in the land, Smith was not disposed to doubt it. The priestess' willingness to let him leave her unhindered, yes, even her scornful laughter as he looked back, told the same story. Whatever Thag might be, his power in this land could not be doubted. He made up his mind suddenly what he must do, and turned to the breathlessly waiting little folk. ”

“ For he still could not focus directly upon the shining whiteness of her, and nothing save those moonstone eyes were clear to him.
The girl sprang to her feet and rose on tiptoe, gripping his shoulders with urgent hands. Again the blind intensity of her eyes took hold of his, with a force almost as tangible as the clutch of her hands; again that stream of intelligence poured into his brain, strongly, pleadingly. ”

“ After all, this thing wore the aspect of an old pattern, and in that pattern there was nothing dreadful. The tree of life had made up the design upon that well-top in Illar through whose shadow he had entered here, and nothing in that bronze grille-work had roused terror. Then why——? What living menace dwelt invisibly among these branches to twist them into curves of horror? ”

“ The branches gathered her closer in their embrace. Now the blossoms arched near, curving down all about her, touching her very gently, twisting their blazing faces toward the focus of her moon-white body. ”

“ The dryland race today is a handful of semi-brutes, degenerate from the ages of past time when they were a mighty people at the apex of an almost forgotten glory. That day is millions of years gone now, too far in the past to have record save in the vaguest folklore. ”

“ Queer. This must have been a private court, then, its great grille-crowned well reserved for the use of the priests. Or wait—had there not been a priest-king Illar after whom the city was named? A wizard-king, so legend said, who ruled temple as well as palace with an iron hand. This elaborately patterned well, of material royal enough to withstand the weight of ages, might well have been sacrosanct for the use of that long-dead monarch. It might——
Across the sun-bright pavement swept the shadow of a plane. ”
