The hall was slightly inclined; and he seemed to remember that the upward grade would presumably lead to a lost world of freedom. Apprehensively and furtively, he began to follow it, loping like an animal.

After he had gone for perhaps a mile, the floor became perfectly level, but the hall itself started to turn in a sort of arc. He was unable to see very far ahead. Then, so abruptly that he could not check his headlong flight, he came in view of three Oumnis, clothed in metal, who were all standing with their backs to him. A boat-vehicle was near at hand. One of the Immortals was tugging at a huge, capstan-like bar that protruded from the wall of the passage; and as if in response to the bar, a sort of gleaming metal valve was descending slowly from the roof. Inch by inch, it came down like a mighty curtain; and soon it would close the entire passage and render impossible the earth-man’s egress.

Somehow, it did not occur to Howard that the tunnel beyond the valve might lead to other realms than the outer air for which he longed so desperately. As if by a miracle, something of his former courage and resourcefulness had returned to him; and he did not turn and flee incontinently at sight of the Immortals, as he would have done a short time before. He felt that now or never was his opportunity to escape from the sub-Mercutian levels.

Leaping forward on the unsuspecting Oumnis, all of whom were intent on the closing of the valve, he struck at the foremost with his metal bar. The Mercutian toppled and went down with a clattering of mouffa on the floor. The one who was operating the lever continued his task, and Howard had no time to strike him down, for the remaining Immortal, with tigerish agility, had sprung back and was levelling the deadly fire-tube which he carried.

Howard saw that the great valve was still descending—was barely two feet above the cavern floor. He made a flying dive for the opening, sprawling on all fours and then crawling prone on his stomach beneath the terrible curtain of metal.

Struggling to rise, he found himself impeded and held back. He was in utter darkness now; but getting to his knees and groping about, he determined the cause of his retardation. The fallen valve had caught the loose elongated heel of the mouffa on his right foot. He had all the sensations of a trapped animal as he sought to wrench himself free. The tough mouffa held, weighed down by the enormous valve; and it seemed that there was no escape.

Then, amid his desperation, he somehow remembered that the mouffa-armor was open at the breast. Awkwardly and painfully, he managed to crawl forth from it, leaving it there like a discarded lizard-skin.

Getting to his feet, he raced on in the darkness. He was without light, for he had dropped the phosphorescent bough in his dive under the closing valve. The cavern was rough and flinty to his naked feet; and he felt an icy wind, bleak as the breath of glaciers, that blew upon him as he went. The floor sloped upward, and in places it was broken into stair-like formations against which he stumbled and fell, bruising himself severely. Then he cut his head cruelly on a sharp stone that projected from the low roof. The wet, warm blood flowed down across his brow and into his eyes.

The passage steepened and the air took on a terrible frigidity. There was no sign of pursuit from the Oumnis; but fearing they would raise the valve and follow him, the earth-man hastened on. He was puzzled by the growing Arctic cold, but the suppositional reason seemed to elude him. His naked limbs and torso were studded with goose-flesh; and he began to shiver with violent ague, in spite of the high speed at which he ran and climbed.

Now the cavern-stairs were more regular and defined. They seemed to mount forever in the darkness; and growing accustomed to them he was able to grope his way from step to step with no more than an occasional fall or stumble. His feet were cut and bleeding; but the cold had begun to numb them and he felt little pain.

He saw a dim, circular patch of light far above him, and gasping with the icy air, which appeared to grow thinner and more irrespirable, he rushed toward it. Hundreds, thousands of those black, glaciated steps he seemed to climb before he neared the light. He came out beneath a sable heaven crowded with chill, pulseless, glaring stars, in a sort of valley-bottom among drear unending scarps and pinnacles, still and silent as a frozen dream of death. They gleamed in the starlight with reflections of myriad-angled ice; and the valley-bottom itself was lit by patches of a leprous whiteness. One of these patches fringed the mouth of the incline on whose topmost step the earth-man was standing.

He fought agonizingly for breath in the tenuous infra-zero air and his body stiffened momently with a permeating rigor as he stood and peered in numb bewilderment at the icy, mountainous chaos of the landscape in which he had emerged. It was like a dead crater in a world of unspeakable and perpetual desolation, where life could never have been.

The flowing blood had congealed upon his brow and cheeks. With glazing eyes, he saw, in a nearby cliff, the continuation of the cavern-steps. Hewn for some unimaginable purpose by the Immortals, they ran upward in the ice toward the higher summits.

It was not the familiar twilight zone of Mercury in which he had come forth—it was the bleak, nightward side, eternally averted from the sun, and blasted with the frightful cold of cosmic space. He felt the pinnacles and chasms close him in, relentless and rigid, like some hyperborean hell. Then the realization of his plight became something very remote and recessive, a dim thought that floated above his ebbing consciousness. He fell forward on the snow with limbs already stiff and unbending; and the mercy of the final numbness grew complete.

THE EMPIRE OF THE NECROMANCERS

The legend of Mmatmuor and Sodosma shall arise only in the latter cycles of Earth, when the glad legends of the prime have been forgotten. Before the time of its telling, many epochs shall have passed away, and the seas shall have fallen in their beds, and new continents shall have come to birth. Perhaps, in that day, it will serve to beguile for a little the black weariness of a dying race, grown hopeless of all but oblivion. I tell the tale as men shall tell it in Zothique, the last continent, beneath a dim sun and sad heavens where the stars come out in terrible brightness before eventide.

I

Mmatmuor and Sodosma were necromancers who came from the dark isle of Naat, to practise their baleful arts in Tinarath, beyond the shrunken seas. But they did not prosper in Tinarath: for death was deemed a holy thing by the people of that grey country; and the nothingness of the tomb was not lightly to be desecrated; and the raising up of the dead by necromancy was held in abomination.

So, after a short interval, Mmatmuor and Sodosma were driven forth by the anger of the inhabitants, and were compelled to flee toward Cincor, a desert of the south, which was peopled only by the bones and mummies of a race that the pestilence had slain in former time.

The land into which they went lay drear and leprous and ashen below the huge, ember-colored sun. Its crumbling rocks and deathly solitudes of sand would have struck terror to the hearts of common men; and since they had been thrust out in that barren place without food or sustenance, the plight of the sorcerers might well have seemed a desperate one. But, smiling secretly, with the air of conquerors who tread the approaches of a long-coveted realm, Sodosma and Mmatmuor walked steadily on into Cincor.

Unbroken before them, through fields devoid of trees and grass, and across the channels of dried-up rivers, there ran the great highway by which travellers had gone formerly between Cincor and Tinarath. Here they met no living thing; but soon they came to the skeletons of a horse and its rider, lying full in the road, and wearing still the sumptuous harness and raiment which they had worn in the flesh. And Mmatmuor and Sodosma paused before the piteous bones, on which no shred of corruption remained; and they smiled evilly at each other.
