They tied the weary horses in a clump of tamarisk and without further comment turned up the slope. There was no cover. It was a naked incline, strewn with boulders not big enough to conceal a man. But they did conceal something else.
The party had not gone fifty steps when a snarling shape burst from behind a rock. It was one of the gaunt savage dogs that infested the hill villages, and its eyes glared redly, its jaws dripped foam. Conan was leading, but it did not attack him. It dashed past him and leaped at Kerim Shah. The Turanian leaped aside, and the great dog flung itself upon the Irakzai behind him. The man yelled and threw up his arm, which was torn by the brute"s fangs as it bore him backward, and the next instant half a dozen tulwars were hacking at the beast Yet not until it was literally dismembered did the hideous creature cease its efforts to seize and rend its attackers.
Kerim Shah bound up the wounded warrior"s gashed arm, looked at him narrowly, and then turned away without a word. He rejoined Conan, and they renewed the climb in silence.
Presently Kerim Shah said: "Strange to find a village dog in this place."
"There"s no offal here," grunted Conan.
Both turned their heads to glance back at the wounded warrior toiling after them among his companions. Sweat glistened on his dark face and his lips were drawn back from his teeth in a grimace of pain. Then both looked again at the stone tower squatting above them.
A slumberous quiet lay over the uplands. The tower showed no sign of life; nor did the strange pyramidal structure beyond it But the men who toiled upward went with the tenseness of men walking on the edge of a crater. Kerim Shah had unslung the powerful Turanian bow that killed at five hundred paces, and the Irakzai looked to their own lighter and less lethal bows.
But they were not within bow-shot of the tower when something shot down out of the sky without warning, h pa.s.sed so close to Conan that he felt the wind of the rushing wings, but it was an Irakzai who staggered and fell, blood jetting from a severed jugular. A hawk with wings like burnished steel shot up again, blood" dripping from the scimitar-beak, to reel against the sky as Kerim Shah"s bowstring tw.a.n.ged. It dropped like a plummet, but no man saw where it struck the earth.
Conan bent over the victim of the attack, but the man was already dead.
No one spoke; useless to comment on the fact that never before had a hawk been known to swoop on a man. Red rage began to vie with fatalistic lethargy in the wild souls of the Irakzai. Hairy fingers nocked arrows and men glared vengefully at the tower whose very silence mocked them.
But the next attack came swiftly. They all saw it-a white puffball of smoke that tumbled over the tower-rim and came drifting and rolling down the slope toward them. Others followed it They seemed harmless, mere woolly globes of cloudy foam, but Conan stepped aside to avoid contact with the first. Behind him one of the Irakzai reached out and thrust his sword into the unstable ma.s.s. Instantly a sharp report shook the mountainside. There was a burst of blinding flame, and then the puffball had vanished, and of the too-curious warrior remained only a heap of charred and blackened bones. The crisped hand still gripped the ivory sword-hilt, but the blade was gone-melted and destroyed by that awful heat. Yet men standing almost within reach of the victim had not suffered except to be dazzled and half blinded by the sudden flare.
"Steel touches it off," grunted Conan. "Look out- here they come!"
The slope above them was almost covered by the billowing spheres. Kerim Shah bent his bow and sent a shaft into the ma.s.s, and those touched by the arrow burst like bubbles in spurting flame. His men followed his example and for the next few minutes it was as if a thunderstorm raged on the mountain slope, with bolts of lightning striking and bursting in showers of flame. When the barrage ceased, only a few arrows were left in the quivers of the archers.
They pushed on grimly, over soil charred and blackened, where the naked rock had in places been turned to lava by the explosion of those diabolical bombs.
Now they were almost within arrowflight of the silent tower, and they spread their line, nerves taut, ready for any horror that might descend upon them.
On the tower appeared a single figure, lifting a ten-foot bronze horn.
Its strident bellow roared out across the echoing slopes, like the blare of trumpets on Judgment Day. And it began to be fearfully answered. The ground trembled under the feet of the invaders, and rumblings and grindings welled up from the subterranean depths.
The Irakzai screamed, reeling like drunken men on the shuddering slope, and Conan, eyes glaring, charged recklessly up the incline, knife in hand, straight at the door that showed in the tower-wall. Above him the great horn roared and bellowed in brutish mockery. And then Kerim Shah drew a shaft to his ear and loosed.
Only a Turanian could have made that shot. The bellowing of the horn ceased suddenly, and a high, thin scream shrilled in its place. The green-robed figure oh the tower staggered, clutching at the long shaft which quivered in its bosom, and then pitched across the parapet. The great horn tumbled upon the battlement and hung precariously, and another robed figure rushed to seize it, shrieking in horror. Again the Turanian bow tw.a.n.ged, and again it was answered by a death-howl. The second acolyte, in falling, struck the horn with his elbow and blocked it clattering over the parapet to shatter on the rocks far below.
At such headlong speed had Conan covered the ground that before the clattering echoes of that fall had died away, he was hacking at the door. Warned by his savage instinct, he gave back suddenly as a tide of molten lead splashed down from above. But the next instant he was back again, attacking the panels with redoubled fury. He was galvanized by the fact that his enemies had resorted to earthly weapons. The sorcery of the acolytes was limited. Their necromantic resources might well be exhausted.
Kerim Shah was hurrying up the slope, his hillmen behind him in a straggling crescent. They loosed as they ran, their arrows splintering against the walls or arching over the parapet.
The heavy teak portal gave way beneath the Cimmerian"s a.s.sault, and he peered inside warily, expecting anything. He was looking into a circular chamber from which a stair wound upward. On the opposite side of the chamber a door gaped open, revealing the outer slope- and the backs of half a dozen green-robed figures in full retreat.
Conan yelled, took a step into the tower, and then native caution jerked him back, just as a great block of stone fell crashing to the floor where his foot had been an instant before. Shouting to his followers, he raced around the tower.
The acolytes had evacuated their first line of defense. As Conan rounded the tower he saw their green robes twinkling up the mountain ahead of him. He gave chase, panting with earnest blood-l.u.s.t, 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 plummetlike.
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 diem, 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 pa.s.sed 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 armpits. He felt it 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 handholds 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 is 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 sec 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 spun of rock that ranged 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 a 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 cas.e.m.e.nts 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 const.i.tuted, 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 p.r.o.ng 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 gla.s.sy 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.
