“Shut the door,” advised Valeria. “I’d hate to have to outrun a dragon down this hall.”

  Conan grinned, and replied: “I don’t believe the dragons ever leave the forest.”

  But he complied, and pointed out the broken bolt on the inner side.

  “I thought I heard something snap when I shoved against it. That bolt’s freshly broken. Rust has eaten nearly through it. If the people ran away, why should it have been bolted on the inside?”

  “They undoubtedly left by another door,” suggested Valeria.

  She wondered how many centuries had passed since the light of outer day had filtered into that great hall through the open door. Sunlight was finding its way somehow into the hall, and they quickly saw the source. High up in the vaulted ceiling skylights were set in slot-like openings—translucent sheets of some crystalline substance. In the splotches of shadow between them, the green jewels winked like the eyes of angry cats. Beneath their feet the dully lurid floor smoldered with changing hues and colors of flame. It was like treading the floors of Hell with evil stars blinking overhead.

  Three balustraded galleries ran along on each side of the hall, one above the other.

  “A four-storied house,” grunted Conan, “and this hall extends to the roof. It’s long as a street. I seem to see a door at the other end.”

  Valeria shrugged her white shoulders.

  “Your eyes are better than mine, then, though I’m accounted sharp eyed among the sea-rovers.”

  They turned into an open door at random, and traversed a series of empty chambers, floored like the hall, and with walls of the same green jade, or of marble or ivory or chalcedony, adorned with friezes of bronze, gold, or silver. In the ceilings the green fire-gems were set, and their light was as ghostly and illusive as Conan had predicted. Under the witch-fire glow the intruders moved like specters.

  Some of the chambers lacked this illumination, and their doorways showed black as the mouth of the Pit. These Conan and Valeria avoided, keeping always to the lighted chambers.

  Cobwebs hung in the corners, but there was no perceptible accumulation of dust on the floor, or on the tables and seats of marble, jade, or carnelian which occupied the chambers. Here and there were rugs of that silk known as Khitan which is practically indestructible. Nowhere did they find any windows, or doors opening into streets or courts. Each door merely opened into another chamber or hall.

  “Why don’t we come to a street?” grumbled Valeria. “This palace or whatever we’re in must be as big as the king of Turan’s seraglio.”

  “They must not have perished of plague,” sad Conan, meditating upon the mystery of the empty city. “Otherwise we’d find skeletons. Maybe it became haunted, and everybody got up and left. Maybe—”

  “Maybe, hell!” broke in Valeria rudely. “We’ll never know. Look at these friezes. They portray men. What race do they belong to?”

  Conan scanned them and shook his head.

  “I never saw people exactly like them. But there’s the smack of the East about them—Vendhya, maybe, or Kosala.”

  “Were you a king in Kosala?” she asked, masking her keen curiosity with derision.

  “No. But I was a war chief of the Afghulis who live in the Himelian mountains above the borders of Vendhya. These people favor the Kosalans. But why should Kosalans be building a city this far to the west?”

  The figures portrayed were those of slender, olive-skinned men and women, with finely chiseled, exotic features. They wore filmy robes and many delicate jeweled ornaments, and were depicted mostly in attitudes of feasting, dancing, or lovemaking.

  “Easterners, all right,” grunted Conan, “but from where I don’t know. They must have lived a disgustingly peaceful life, though, or they’d have scenes of wars and fights. Let’s go up those stairs.”

  It was an ivory spiral that wound up from the chamber in which they were standing. They mounted three flights and came into a broad chamber on the fourth floor, which seemed to be the highest tier in the building. Skylights in the ceiling illuminated the room, in which light the fire-gems winked pallidly. Glancing through the doors they saw, except on one side, a series of similarly lighted chambers. This other door opened upon a balustraded gallery that overhung a hall much smaller than the one they had recently explored on the lower floor.

  “Hell!” Valeria sat down disgustedly on a jade bench. “The people who deserted this city must have taken all their treasures with them. I’m tired of wandering through these bare rooms at random.”

  “All these upper chambers seem to be lighted,” said Conan. “I wish we could find a window that overlooked the city. Let’s have a look through that door over there.”

  “You have a look,” advised Valeria. “I’m going to sit here and rest my feet.”

  Conan disappeared through the door opposite that one opening upon the gallery, and Valeria leaned back with her hands clasped behind her head, and thrust her booted legs out in front of her. These silent rooms and halls with their gleaming green clusters of ornaments and burning crimson floors were beginning to depress her. She wished they could find their way out of the maze into which they had wandered and emerge into a street. She wondered idly what furtive, dark feet had glided over those flaming floors in past centuries, how many deeds of cruelty and mystery those winking ceiling-gems had blazed down upon.

  It was a faint noise that brought her out of her reflections. She was on her feet with her sword in her hand before she realized what had disturbed her. Conan had not returned, and she knew it was not he that she had heard.

  The sound had come from somewhere beyond the door that opened on to the gallery. Soundlessly in her soft leather boots she glided through it, crept across the balcony and peered down between the heavy balustrades.

  A man was stealing along the hall.

  The sight of a human being in this supposedly deserted city was a startling shock. Crouching down behind the stone balusters, with every nerve tingling, Valeria glared down at the stealthy figure.

  The man in no way resembled the figures depicted on the friezes. He was slightly above middle height, very dark, though not Negroid. He was naked but for a scanty silk clout that only partly covered his muscular hips, and a leather girdle, a hand’s breadth broad, about his lean waist. His long black hair hung in lank strands about his shoulders, giving him a wild appearance. He was gaunt, but knots and cords of muscles stood out on his arms and legs, without that fleshy padding that presents a pleasing symmetry of contour. He was built with an economy that was almost repellent.

  Yet it was not so much his physical appearance as his attitude that impressed the woman who watched him. He slunk along, stooped in a semi-crouch, his head turning from side to side. He grasped a wide-tipped blade in his right hand and she saw it shake with the intensity of the emotion that gripped him. He was afraid, trembling in the grip of some dire terror. When he turned his head she caught the blaze of wild eyes among the lank strands of black hair.

  He did not see her. On tiptoe he glided across the hall and vanished through an open door. A moment later she heard a choking cry, and then silence fell again.

  Consumed with curiosity, Valeria glided along the gallery until she came to a door above the one through which the man had passed. It opened into another, smaller gallery that encircled a large chamber.

  This chamber was on the third floor, and its ceiling was not so high as that of the hall. It was lighted only by the fire-stones, and their weird green glow left the spaces under the balcony in shadows.

  Valeria’s eyes widened. The man she had seen was still in the chamber.

  He lay face down on a dark crimson carpet in the middle of the room. His body was limp, his arms spread wide. His curved sword lay near him.

  She wondered why he should lie there so motionless. Then her eyes narrowed as she stared down at the rug on which he lay. Beneath and about him the fabric showed a slightly different color, a deeper, brighter crimson.

  Shivering s
lightly, she crouched down closer behind the balustrade, intently scanning the shadows under the overhanging gallery. They gave up no secret.

  Suddenly another figure entered the grim drama. He was a man similar to the first, and he came in by a door opposite that which gave upon the hall.

  His eyes glared at the sight of the man on the floor, and he spoke something in a staccato voice that sounded like “Chicmec!” The other did not move.

  The man stepped quickly across the floor, bent, gripped the fallen man’s shoulder and turned him over. A choking cry escaped him as the head fell back limply, disclosing a throat that had been severed from ear to ear.

  The man let the corpse fall back upon the bloodstained carpet, and sprang to his feet, shaking like a windblown leaf. His face was an ashy mask of fear. But with one knee flexed for flight, he froze suddenly, became as immobile as an image, staring across the chamber with dilated eyes.

  In the shadows beneath the balcony a ghostly light began to glow and grow, a light that was not part of the fire-stone gleam. Valeria felt her hair stir as she watched it; for, dimly visible in the throbbing radiance, there floated a human skull, and it was from this skull—human yet appallingly misshapen—that the spectral light seemed to emanate. It hung there like a disembodied head, conjured out of night and the shadows, growing more and more distinct; human, and yet not human as she knew humanity.

  The man stood motionless, an embodiment of paralyzed horror, staring fixedly at the apparition. The thing moved out from the wall and a grotesque shadows moved with it. Slowly the shadow became visible as a manlike figure whose naked torso and limbs shone whitely, with the hue of bleached bones. The bare skull on its shoulders grinned eyelessly, in the midst of its unholy nimbus, and the man confronting it seemed unable to take his eyes from it. He stood still, his sword dangling from nerveless fingers, on his face the expression of a man bound by the spells of a mesmerist.

  Valeria realized that it was not fear alone that paralyzed him. Some hellish quality of that throbbing glow had robbed him of his power to think and act. She herself, safely above the scene, felt the subtle impact of a nameless emanation that was a threat to sanity.

  The horror swept toward its victim and he moved at last, but only to drop his sword and sink to his knees, covering his eyes with his hands. Dumbly he awaited the stroke of the blade that now gleamed in the apparition’s hand as it reared above him like Death triumphant over mankind.

  Valeria acted according to the first impulse of her wayward nature. With one tigerish movement she was over the balustrade and dropping to the floor behind the awful shape. It wheeled at the thud of her soft boots on the floor, but even as it turned, her keen blade lashed down, and a fierce exultation swept her as she felt the edge cleave solid flesh and mortal bone.

  The apparition cried out gurglingly and went down, severed through the shoulder, breastbone and spine, and as it fell the burning skull rolled clear, revealing a lank mop of black hair and a dark face twisted in the convulsions of death. Beneath the horrific masquerade there was a human being, a man similar to the one kneeling supinely on the floor.

  The latter looked up at the sound of the blow and the cry, and now he glared in wild-eyed amazement at the white-skinned woman who stood over the corpse with a dripping sword in her hand.

  He staggered up, yammering as if the sight had almost unseated his reason. She was amazed to realize that she understood him. He was gibbering in the Stygian tongue, though in a dialect unfamiliar to her.

  “Who are you? Whence come you? What do you in Xuchotl?” Then rushing on, without waiting for her to reply: “But you are a friend—goddess or devil, it makes no difference! You have slain the Burning Skull! It was but a man beneath it, after all! We deemed it a demon they conjured up out of the catacombs! Listen!”

  He stopped short in his ravings and stiffened, straining his ears with painful intensity. The girl heard nothing.

  “We must hasten!” he whispered. “They are west of the Great Hall! They may be all around us here! They may be creeping upon us even now!”

  He seized her wrist in a convulsive grasp she found hard to break.

  “Whom do you mean by ‘they?’” she demanded.

  He stared at her uncomprehendingly for an instant, as if he found her ignorance hard to understand.

  “They?” he stammered vaguely. “Why—why, the people of Xotalanc! The clan of the man you slew. They who dwell by the eastern gate.”

  “You mean to say this city is inhabited?” she exclaimed.

  “Aye! Aye!” He was writhing in the impatience of apprehension. “Come away! Come quick! We must return to Tecuhltli!”

  “Where is that?” she demanded.

  “The quarter by the western gate!” He had her wrist again and was pulling her toward the door through which he had first come. Great beads of perspiration dripped from his dark forehead, and his eyes blazed with terror.

  “Wait a minute!” she growled, flinging off his hand. “Keep your hands off me, or I’ll split your skull. What’s all this about? Who are you? Where would you take me?”

  He took a firm grip on himself, casting glances to all sides, and began speaking so fast his words tripped over each other.

  “My name is Techotl. I am of Techultli. I and this man who lies with his throat cut came into the Halls of Silence to try and ambush some of the Xotalancas. But we became separated and I returned here to find him with his gullet slit. The Burning Skull did it, I know, just as he would have slain me had you not killed him. But perhaps he was not alone. Others may be stealing from Xotalanc! The gods themselves blench at the fate of those they take alive!”

  At the thought he shook as with a ague and his dark skin grew ashy. Valeria frowned puzzledly at him. She sensed intelligence behind this rigmarole, but it was meaningless to her.

  She turned toward the skull, which still glowed and pulsed on the floor, and was reaching a booted toe tentatively toward it, when the man who called himself Techotl sprang forward with a cry.

  “Do not touch it! Do not even look at it! Madness and death lurk in it. The wizards of Xotalanc understand its secret—they found it in the catacombs, where lie the bones of terrible kings who ruled in Xuchotl in the black centuries of the past. To gaze upon it freezes the blood and withers the brain of a man who understands not its mystery. To touch it causes madness and destruction.”

  She scowled at him uncertainly. He was not a reassuring figure, with his lean, muscle-knotted frame, and snaky locks. In his eyes, behind the glow of terror, lurked a weird light she had never seen in the eyes of a man wholly sane. Yet he seemed sincere in his protestations.

  “Come!” he begged, reaching for her hand, and then recoiling as he remembered her warning. “You are a stranger. How you came here I do not know, but if you were a goddess or a demon, come to aid Tecuhltli, you would know all the things you have asked me. You must be from beyond the great forest, whence our ancestors came. But you are our friend, or you would not have slain my enemy. Come quickly, before the Xotalancas find us and slay us!”

  From his repellent, impassioned face she glanced to the sinister skull, smoldering and glowing on the floor near the dead man. It was like a skull seen in a dream, undeniably human, yet with disturbing distortions and malformations of contour and outline. In life the wearer of that skull must have presented an alien and monstrous aspect. Life? It seemed to possess some sort of life of its own. Its jaws yawned at her and snapped together. Its radiance grew brighter, more vivid, yet the impression of nightmare grew too; it was a dream; all life was a dream—it was Techotl’s urgent voice which snapped Valeria back from the dim gulfs whither she was drifting.

  “Do not look at the skull! Do not look at the skull!” It was a far cry from across unreckoned voids.

  Valeria shook herself like a lion shaking his mane. Her vision cleared. Techotl was chattering: “In life it housed the awful brain of a king of magicians! It holds still the life and fire of magic drawn from outer spaces!?
??

  With a curse Valeria leaped, lithe as a panther, and the skull crashed to flaming bits under her swinging sword. Somewhere in the room, or in the void, or in the dim reaches of her consciousness, an inhuman voice cried out in pain and rage.

  Techotl’s hand was plucking at her arm and he was gibbering: “You have broken it! You have destroyed it! Not all the black arts of Xotalanc can rebuild it! Come away! Come away quickly, now!”

  “But I can’t go,” she protested. “I have a friend somewhere nearby—”

  The flare of his eyes cut her short as he stared past her with an expression grown ghastly. She wheeled just as four men rushed through as many doors, converging on the pair in the center of the chamber.

  They were like the others she had seen, the same knotted muscles bulging on otherwise gaunt limbs, the same lank blue-black hair, the same mad glare in their wild eyes. They were armed and clad like Techotl, but on the breast of each was painted a white skull.

  There were no challenges or war-cries. Like blood-mad tigers the men of Xotalanc sprang at the throats of their enemies. Techotl met them with the fury of desperation, ducked the swipe of a wide-headed blade, and grappled with the wielder, and bore him to the floor where they rolled and wrestled in murderous silence.

  The other three swarmed on Valeria, their weird eyes red as the eyes of mad dogs.

  She killed the first who came within reach before he could strike a blow, her long straight blade splitting his skull even as his own sword lifted for a stroke. She sidestepped a thrust, even as she parried a slash. Her eyes danced and her lips smiled without mercy. Again she was Valeria of the Red Brotherhood, and the hum of her steel was like a bridal song in her ears.

  Her sword darted past a blade that sought to parry, and sheathed six inches of its point in a leather-guarded midriff. The man gasped agonizedly and went to his knees, but his tall mate lunged in, in ferocious silence, raining blow on blow so furiously that Valeria had no opportunity to counter. She stepped back coolly, parrying the strokes and watching for her chance to thrust home. He could not long keep up that flailing whirlwind. His arm would tire, his wind would fail; he would weaken, falter, and then her blade would slide smoothly into his heart. A sidelong glance showed her Techotl kneeling on the breast of his antagonist and striving to break the other’s hold on his wrist and to drive home a dagger.
