three-dimensionally upon the twilight. Its dreadfully curving branches had been no more than Thag’s barest contours, yet even they had made his very soul sick with intuitive revulsion. But now, seeing the true horror, his mind was too numb to do more than register its presence: Thag, hovering monstrously between earth and heaven, billowing and surging up there in the translucent twilight, tethered to the ground by the Tree’s bending stem and reaching ravenously after the hypnotized fodder that his calling brought helpless into his clutches. One by one he snatched them up, one by one absorbed them into the great, unseeable horror of his being. That, then, was the reason why they vanished so instantaneously, sucked into the concealing folds of a thing too dreadful for normal eyes to see.
The priestess was pacing forward. Above her the branches arched and leaned. 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. Foolishly his brain wandered among the ramifications of what had happened so long ago that time itself had forgotten, refusing to recognize the fate that was upon himself. He knew a tingle of respect for the ages-dead wizard who had dared command a being like this to his services—this vast, blind, hovering thing, ravenous for human flesh, indistinguishable even now save in those terrible outlines that sent panic leaping through him with every motion of the Tree’s fearful symmetry.
All this flashed through his dazed mind in the one blinding instant of understanding. Then the priestess’ luminous whiteness swam up before his hypnotized stare. Her hands were upon him, gently guiding his mechanical footsteps, very gently leading him forward into—into—
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. And when that ultimate intensity of terror struck the basic flint of him, reaching down through mind and soul into the deepest depths of his being, it struck a spark from that inflexible barbarian buried at the roots of him which had force enough to shock him out of his stupor.
In the instant of release his hand swept like an unloosed spring, of its own volition, straight for the butt of his power-gun. He was dragging it free as the Tree’s branches snatched him from its priestess’ hands. The fire-colored blossoms burnt his flesh as they closed round him, the hot branches gripping like the touch of ravenous fingers. The whole Tree was hot and throbbing with a dreadful travesty of fleshly life as it whipped him aloft into the hovering bulk of incarnate horror above.
In the instantaneous upward leap of the flower-tipped limbs Smith fought like a demon to free his gun-hand from the gripping coils. For the first time Thag knew rebellion in his very clutches, and the ecstasy of that music which had dinned in Smith’s ears so strongly that by now it seemed almost silence was swooping down a long arc into wrath, and the branches tightened with hot insistency, lifting the rebellious offering into Thag’s monstrous, indescribable bulk.
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. 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.
He saw the flame leap in a dazzling gush straight for the trunk below. It struck. He heard the sizzle of annihilated matter. He saw the trunk quiver convulsively from the very roots, and the whole fabulous Tree shook once with an ominous tremor. But before that tremor could shiver up the branches to him the hum of the living dynamo which was closing round his body shrilled up arcs of pure intensity into a thundering silence.
Then without a moment’s warning the world exploded. So instantaneously did all this happen that the gun-blast’s roar had not yet echoed into silence before a mightier sound than the brain could bear exploded outward from the very center of his own being. Before the awful power of it everything reeled into a shaken oblivion. He felt himself falling.…

A queer, penetrating light shining upon his closed eyes roused Smith by degrees into wakefulness again. He lifted heavy lids and stared upward into the unwinking eye of Mars’ racing nearer moon. He lay there blinking dazedly for a while before enough of memory returned to rouse him. Then he sat up painfully, for every fiber of him ached, and stared round on a scene of the wildest destruction. He lay in the midst of a wide, rough circle which held nothing but powdered stone. About it, rising raggedly in the moving moonlight, the blocks of time-forgotten Illar loomed.
But they were no longer piled one upon another in a rough travesty of the city they once had shaped. Some force mightier than any of man’s explosives seemed to have hurled them with such violence from their beds that their very atoms had been disrupted by the force of it, crumbling them into dust. And in the very center of the havoc lay Smith, unhurt.
He stared in bewilderment about the moonlight ruins. In the silence it seemed to him that the very air still quivered in shocked vibrations. And as he stared he realized that no force save one could have wrought such destruction upon the ancient stones. Nor was there any explosive known to man which would have wrought this strange, pulverizing havoc upon the blocks of Illar. That force had hummed unbearably through the living dynamo of Thag, a force so powerful that space itself had bent to enclose it. Suddenly he realized what must have happened.
Not Illar, but Thag himself had warped the walls of space to enfold the twilit world, and nothing but Thag’s living power could have held it so bent to segregate the little, terror-ridden land inviolate.
Then when the Tree’s roots parted, Thag’s anchorage in the material world failed and in one great gust of unthinkable energy the warped space-walls had ceased to bend. Those arches of solid space had snapped back into their original pattern, hurling the land and all its dwellers into—into— His mind balked in the effort to picture what must have happened, into what ultimate dimension those denizens must have vanished.
Only himself, enfolded deep in Thag’s very essence, the intolerable power of the explosion had not touched. So when the warped space-curve ceased to be, and Thag’s hold upon reality failed, he must have been dropped back out of the dissolving folds upon the spot where the Tree had stood in the space-circled world, through that vanished world-floor into the spot he had been snatched from in the instant of the dim land’s dissolution. It must have happened after the terrible force of the explosion had spent itself, before Thag dared move even himself through the walls of changing energy into his own far land again.
Smith sighed and lifted a hand to his throbbing head, rising slowly to his feet. What time had elapsed he could not guess, but he must assume that the Patrol still searched for him. Wearily he set out across the circle of havoc toward the nearest shelter which Illar offered. The dust rose in ghostly, moonlit clouds under his feet.
