The People of the Black Circle

raced around the tower. The acolytes had evacuated their first line of defence. As Conan rounded the tower he saw their green robes twinkling up the mountain ahead of him. He gave chase, panting with earnest blood-lust, and behind him Kerim Shah and the Irakzai came pelting, the latter yelling like wolves at the flight of their enemies, their fatalism momentarily submerged by temporary triumph. The tower stood on the lower edge of a narrow plateau whose upward slant was barely perceptible. A few hundred yards away this plateau ended abruptly in a chasm which had been invisible farther down the mountain. Into this chasm the acolytes apparently leaped without checking their speed. Their pursuers saw the green robes flutter and disappear over the edge. A few moments later they themselves were standing on the brink of the mighty moat that cut them off from the castle of the Black Seers. It was a sheer-walled ravine that extended in either direction as far as they could see, apparently girdling the mountain, some four hundred yards in width and five hundred feet deep. And in it, from rim to rim, a strange, translucent mist sparkled and shimmered. Looking down, Conan grunted. Far below him, moving across the glimmering floor, which shone like burnished silver, he saw the forms of the green-robed acolytes. Their outline was wavering and indistinct, like figures seen under deep water. They walked in single file, moving toward the opposite wall. Kerim Shah nocked an arrow and sent it singing downward. But when it struck the mist that filled the chasm it seemed to lose momentum and direction, wandering widely from its course. 'If they went down, so can we!' grunted Conan, while Kerim Shah stared after his shaft in amazement. 'I saw them last at this spot--' Squinting down he saw something shining like a golden thread across the canyon floor far below. The acolytes seemed to be following this thread, and there suddenly came to him Khemsa's cryptic words--'Follow the golden vein!' On the brink, under his very hand as he crouched, he found it, a thin vein of sparkling gold running from an outcropping of ore to the edge and down across the silvery floor. And he found something else, which had before been invisible to him because of the peculiar refraction of the light. The gold vein followed a narrow ramp which slanted down into the ravine, fitted with niches for hand and foot hold. 'Here's where they went down,' he grunted to Kerim Shah. 'They're no adepts, to waft themselves through the air! We'll follow them--' It was at that instant that the man who had been bitten by the mad dog cried out horribly and leaped at Kerim Shah, foaming and gnashing his teeth. The Turanian, quick as a cat on his feet, sprang aside and the madman pitched head-first over the brink. The others rushed to the edge and glared after him in amazement. The maniac did not fall plummet-like. He floated slowly down through the rosy haze like a man sinking in deep water. His limbs moved like a man trying to swim, and his features were purple and convulsed beyond the contortions of his madness. Far down at last on the shining floor his body settled and lay still. 'There's death in that chasm,' muttered Kerim Shah, drawing back from the rosy mist that shimmered almost at his feet. 'What now, Conan?' 'On!' answered the Cimmerian grimly. 'Those acolytes are human; if the mist doesn't kill them, it won't kill me.' He hitched his belt, and his hands touched the girdle Khemsa had given him; he scowled, then smiled bleakly. He had forgotten that girdle; yet thrice had death passed him by to strike another victim. The acolytes had reached the farther wall and were moving up it like great green flies. Letting himself upon the ramp, he descended warily. The rosy cloud lapped about his ankles, ascending as he lowered himself. It reached his knees, his thighs, his waist, his arm-pits. He felt as one feels a thick heavy fog on a damp night. With it lapping about his chin he hesitated, and then ducked under. Instantly his breath ceased; all air was shut off from him and he felt his ribs caving in on his vitals. With a frantic effort he heaved himself up, fighting for life. His head rose above the surface and he drank air in great gulps. Kerim Shah leaned down toward him, spoke to him, but Conan neither heard nor heeded. Stubbornly, his mind fixed on what the dying Khemsa had told him, the Cimmerian groped for the gold vein, and found that he had moved off it in his descent. Several series of hand-holds were niched in the ramp. Placing himself directly over the thread, he began climbing down once more. The rosy mist rose about him, engulfed him. Now his head was under, but he was still drinking pure air. Above him he saw his companions staring down at him, their features blurred by the haze that shimmered over his head. He gestured for them to follow, and went down swiftly, without waiting to see whether they complied or not. Kerim Shah sheathed his sword without comment and followed, and the Irakzai, more fearful of being left alone than of the terrors that might lurk below, scrambled after him. Each man clung to the golden thread as they saw the Cimmerian do. Down the slanting ramp they went to the ravine floor and moved out across the shining level, treading the gold vein like rope-walkers. It was as if they walked along an invisible tunnel through which air circulated freely. They felt death pressing in on them above and on either hand, but it did not touch them. The vein crawled up a similar ramp on the other wall up which the acolytes had disappeared, and up it they went with taut nerves, not knowing what might be waiting for them among the jutting spurs of rock that fanged the lip of the precipice. It was the green-robed acolytes who awaited them, with knives in their hands. Perhaps they had reached the limits to which they could retreat. Perhaps the Stygian girdle about Conan's waist could have told why their necromantic spells had proven so weak and so quickly exhausted. Perhaps it was knowledge of death decreed for failure that sent them leaping from among the rocks, eyes glaring and knives glittering, resorting in their desperation to material weapons. There among the rocky fangs on the precipice lip was no war of wizard craft. It was a whirl of blades, where real steel bit and real blood spurted, where sinewy arms dealt forthright blows that severed quivering flesh, and men went down to be trodden under foot as the fight raged over them. One of the Irakzai bled to death among the rocks, but the acolytes were down--slashed and hacked asunder or hurled over the edge to float sluggishly down to the silver floor that shone so far below. Then the conquerors shook blood and sweat from their eyes, and looked at one another. Conan and Kerim Shah still stood upright, and four of the Irakzai. They stood among the rocky teeth that serrated the precipice brink, and from that spot a path wound up a gentle slope to a broad stair, consisting of half a dozen steps, a hundred feet across, cut out of a green jade-like substance. They led up to a broad stage or roofless gallery of the same polished stone, and above it rose, tier upon tier, the castle of the Black Seers. It seemed to have been carved out of the sheer stone of the mountain. The architecture was faultless, but unadorned. The many casements were barred and masked with curtains within. There was no sign of life, friendly or hostile. They went up the path in silence, and warily as men treading the lair of a serpent. The Irakzai were dumb, like men marching to a certain doom. Even Kerim Shah was silent. Only Conan seemed unaware what a monstrous dislocating and uprooting of accepted thought and action their invasion constituted, what an unprecedented violation of tradition. He was not of the East; and he came of a breed who fought devils and wizards as promptly and matter-of-factly as they battled human foes. He strode up the shining stairs and across the wide green gallery straight toward the great golden-bound teak door that opened upon it. He cast but a single glance upward at the higher tiers of the great pyramidal structure towering above him. He reached a hand for the bronze prong that jutted like a handle from the door--then checked himself, grinning hardly. The handle was made in the shape of a serpent, head lifted on arched neck; and Conan had a suspicion that that metal head would come to grisly life under his hand. He struck it from the door with one blow, and its bronze clink on the glassy floor did not lessen his caution. He flipped it aside with his knife-point, and again turned to the door. Utter silence reigned over the towers. Far below them the mountain slopes fell away into a purple haze of distance. The sun glittered on snow-clad peaks on either hand. High above, a vulture hung like a black dot in the cold blue of the sky. But for it, the men before the gold-bound door were the only evidence of life, tiny figures on a green jade gallery poised on the dizzy height, with that fantastic pile of stone towering above them. A sharp wind off the snow slashed them, whipping their tatters about. Conan's long knife splintering through the teak panels roused the startled echoes. Again and again he struck, hewing through polished wood and metal bands alike. Through the sundered ruins he glared into the interior, alert and suspicious as a wolf. He saw a broad chamber, the polished stone walls untapestried, the mosaic floor uncarpeted. Square, polished ebon stools and a stone dais formed the only furnishings. The room was empty of human life. Another door showed in the opposite wall. 'Leave a man on guard outside,' grunted Conan. 'I'm going in.' Kerim Shah designated a warrior for that duty, and the man fell back toward the middle of the gallery, bow in hand. Conan strode into the castle, followed by the Turanian and the three remaining Irakzai. The one outside spat, grumbled in his beard, and started suddenly as a low mocking laugh reached his ears. He lifted his head and saw, on the tier above him, a tall, black-robed figure, naked head nodding slightly as he stared down. His whole attitude suggested mockery and malignity. Quick as a flash the Irakzai bent his bow and loosed, and the arrow streaked upward to strike full in the black-robed breast. The mocking smile did not alter. The Seer plucked out the missile and threw it back at the bowman, not as a weapon is hurled, but with a contemptuous gesture. The Irakzai dodged, instinctively throwing up his arm. His fingers closed on the revolving shaft. Then he shrieked. In his hand the wooden shaft suddenly _writhed_. Its rigid outline became pliant, melting in his grasp. He tried to throw it from him, but it was too late. He held a living serpent in his naked hand, and already it had coiled about his wrist and its wicked wedge-shaped head darted at his muscular arm. He screamed again and his eyes became distended, his features purple. He went to his knees shaken by an awful convulsion, and then lay still. The men inside had wheeled at his first cry. Conan took a swift stride toward the open doorway, and then halted short, baffled. To the men behind him it seemed that he strained against empty air. But though he could see nothing, there was a slick, smooth, hard surface under his hands, and he knew that a sheet of crystal had been let down in the doorway. Through it he saw the Irakzai lying motionless on the glassy gallery, an ordinary arrow sticking in his arm. Conan lifted his knife and smote, and the watchers were dumbfounded to see his blow checked apparently in midair, with the loud clang of steel that meets an unyielding substance. He wasted no more effort. He knew
