"They camped before the city, not daring to leave the plain, for the night was made hideous with the noise of the battling monsters through the forest. They made war incessantly upon one another. Yet they came not into the plain.
   "The people of the city shut their gates and shot arrows at our people from the walls. The Tlazitlans were imprisoned on the plain, as if the ring of the forest had been a great wall; for to venture into the woods would have been madness.
   "That night there came secretly to their camp a slave from the city, one of their own blood, who with a band of exploring soldiers had wandered into the forest long before, when he was a young man. The dragons had devoured all his companions, but he had been taken into the city to dwell in servitude. His name was Tolkemec." A flame lighted the dark eyes at mention of the name, and some of the people muttered obscenely and spat. "He promised to open the gates to the warriors. He asked only that all captives taken be delivered into his hands.
   "At dawn he opened the gates. The warriors swarmed in and the halls of Xuchotl ran red. Only a few hundred folk dwelt there, decaying remnants of a once great race. Tolkemec said they came from the east, long ago, from Old Kosala, when the ancestors of those who now dwell in Kosala came up from the south and drove forth the original inhabitants of the land. They wandered far westward and finally found this forest-girdled plain, inhabited then by a tribe of black people.
   "These they enslaved and set to building a city. From the hills to the east they brought jade and marble and lapis lazuli, and gold, silver, and copper. Herds of elephants provided them with ivory. When their city was completed, they slew all the black slaves. And their magicians made a terrible magic to guard the city; for by their necromantic arts they re-created the dragons which had once dwelt in this lost land, and whose monstrous bones they found in the forest. Those bones they clothed in flesh and life, and the living beasts walked the earth as they walked it when time was young. But the wizards wove a spell that kept them in the forest and they came not into the plain.
   "So for many centuries the people of Xuchotl dwelt in their city, cultivating the fertile plain, until their wise men learned how to grow fruit within the city—fruit which is not planted in soil, but obtains its nourishment out of the air—and then they let the irrigation ditches run dry and dwelt more and more in luxurious sloth, until decay seized them. They were a dying race when our ancestors broke through the forest and came into the plain. Their wizards had died, and the people had forgot their ancient necromancy. They could fight neither by sorcery nor the sword.
   "Well, our fathers slew the people of Xuchotl, all except a hundred which were given living into the hands of Tolkemec, who had been their slave; and for many days and nights the halls re-echoed to their screams under the agony of his tortures.
   "So the Tlazitlans dwelt here, for a while in peace, ruled by the brothers Tecuhltli and Xotalanc, and by Tolkemec. Tolkemec took a girl of the tribe to wife, and because he had opened the gates, and because he knew many of the arts of the Xuchotlans, he shared the rule of the tribe with the brothers who had led the rebellion and the flight.
   "For a few years, then, they dwelt at peace within the city, doing little but eating, drinking, and making love, and raising children. There was no necessity to till the plain, for Tolkemec taught them how to cultivate the air-devouring fruits. Besides, the slaying of the Xuchotlans broke the spell that held the dragons in the forest, and they came nightly and bellowed about the gates of the city. The plain ran red with the blood of their eternal warfare, and it was then that—" He bit his tongue in the midst of the sentence, then presently continued, but Valeria and Conan felt that he had checked an admission he had considered unwise.
   "Five years they dwelt in peace. Then"—Olmec's eyes rested briefly on the silent woman at his side—"Xotalanc took a woman to wife, a woman whom both Tecuhltli and old Tolkemec desired. In his madness, Tecuhltli stole her from her husband. Aye, she went willingly enough. Tolkemec, to spite Xotalanc, aided Tecuhltli. Xotalanc demanded that she be given back to him, and the council of the tribe decided that the matter should be left to the woman. She chose to remain with Tecuhltli. In wrath Xotalanc sought to take her back by force, and the retainers of the brothers came to blows in the Great Hall.
   "There was much bitterness. Blood was shed on both sides. The quarrel became a feud, the feud an open war. From the welter three factions emerged—Tecuhltli, Xotalanc, and Tolkemec. Already, in the days of peace, they had divided the city between them. Tecuhltli dwelt in the western quarter of the city, Xotalanc in the eastern, and Tolkemec with his family by the southern gate.
   "Anger and resentment and jealousy blossomed into bloodshed and rape and murder. Once the sword was drawn there was no turning back; for blood called for blood, and vengeance followed swift on the heels of atrocity. Tecuhltli fought with Xotalanc, and Tolkemec aided first one and then the other, betraying each faction as it fitted his purposes. Tecuhltli and his people withdrew into the quarter of the western gate, where we now sit. Xuchotl is built in the shape of an oval. Tecuhltli, which took its name from its prince, occupies the western end of the oval. The people blocked up all doors connecting the quarter with the rest of the city, except one on each floor, which could be defended easily. They went into the pits below the city and built a wall cutting off the western end of the catacombs, where lie the bodies of the ancient Xuchotlans, and of those Tlazitlans slain in the feud. They dwelt as in a besieged castle, making sorties and forrays on their enemies.
   "The people of Xotalanc likewise fortified the eastern quarter of the city, and Tolkemec did likewise with the quarter by the southern gate. The central part of the city was left bare and uninhabited. Those empty halls and chambers became a battleground, and a region of brooding terror.
   "Tolkemec warred on both clans. He was a fiend in the form of a human, worse than Xotalanc. He knew many secrets of the city he never told the others. From the crypts of the catacombs he plundered the dead of their grisly secrets—secrets of ancient kings and wizards, long forgotten by the degenerate Xuchotlans our ancestors slew. But all his magic did not aid him the night we of Tecuhltli stormed his castle and butchered all his people. Tolkemec we tortured for many days."
   His voice sank to a caressing slur, and a faraway look grew in his eyes, as if he looked back over the years to a scene which caused him intense pleasure.
   "Aye, we kept the life in him until he screamed for death as for a bride. At last we took him living from the torture chamber and cast him into a dungeon for the rats to gnaw as he died. From that dungeon, somehow, he managed to escape, and dragged himself into the catacombs. There without doubt he died, for the only way out of the catacombs beneath Tecuhltli is through Tecuhltli, and he never emerged by that way. His bones were never found and the superstitious among our people swear that his ghost haunts the crypts to this day, wailing among the bones of the dead. Twelve years ago we butchered the people of Tolkemec, but the feud raged on between Tecuhltli and Xotalanc, as it will rage until the last man, the last woman is dead.
   "It was fifty years ago that Tecuhltli stole the wife of Xotalanc. Half a century the feud has endured. I was born in it. All in this chamber, except Tascela, were born in it. We expect to die in it.
   "We are a dying race, even as were those Xuchotlans our ancestors slew. When the feud began there were hundreds in each faction. Now we of Tecuhltli number only these you see before you, and the men who guard the four doors: forty in all. How many Xotalancas there are we do not know, but I doubt if they are much more numerous than we. For fifteen years no children have been born to us, and we have seen none among the Xotalancas.
   "We are dying, but before we die we will slay as many of the men of Xotalanc as the gods permit."
   And with his weird eyes blazing, Olmec spoke long of that grisly feud, fought out in silent chambers and dim halls under the blaze of the green fire-jewels, on floors smoldering with the flames of hell and splashed with deeper crimson from severed veins. In that long butchery a whole generation had perished. Xotalanc was dead, long ago, slain in a grim battle on an ivory stair. Tecuhltli was dead, flayed alive by the maddened Xotalancas who had captured him.
   Without emotion Olmec told of hideous battles fought in black corridors, of ambushes on twisting stairs, and red butcheries. With a redder, more abysmal gleam in his deep dark eyes he told of men and women flayed alive, mutilated and dismembered, of captives howling under tortures so ghastly that even the barbarous Cimmerian grunted. No wonder Techotl had trembled with the terror of capture! Yet he had gone forth to slay if he could, driven by hat that was stronger than his fear. Olmec spoke further, of dark and mysterious matters, of black magic and wizardry conjured out of the black night of the catacombs, of weird creatures invoked out of darkness for horrible allies. In these things the Xotalancas had the advantage, for it was in the eastern catacombs where lay the bones of the greatest wizards of the ancient Xuchotlans, with their immemorial secrets.
   Valeria listened with morbid fascination. The feud had become a terrible elemental power driving the people of Xuchotl inexorably on to doom and extinction. It filled their whole lives. They were born in it, and they expected to die in it. They never left their barricaded castle except to steal forth into the Halls of Silence that lay between the opposing fortresses, to slay and be slain. Sometimes the raiders returned with frantic captives, or with grim tokens of victory in fight. Sometimes they did not return at all, or returned only as severed limbs cast down before the bolted bronze doors. It was a ghastly, unreal nightmare existence these people lived, shut off from the rest of the world, caught together like rabid rats in the same trap, butchering one another through the years, crouching and creeping through the sunless corridors to maim and torture and murder.
   While Olmec talked, Valeria felt the blazing eyes of Tascela fixed upon her. The princess seemed not to hear what Olmec was saying. Her expression, as he narrated victories or defeats, did not mirror the wild rage or fiendish exultation that alternated on the faces of the other Tecuhltli. The feud that was an obsession to her clansmen seemed meaningless to her. Valeria found her indifferent callousness more repugnant than Olmec's naked ferocity.
   "And we can never leave the city," said Olmec. "For fifty years on one has left it except those—" Again he checked himself.
   "Even without the peril of the dragons," he continued, "we who were born and raised in the city would not dare leave it. We have never set foot outside the walls. We are not accustomed to the open sky and the naked sun. No; we were born in Xuchotl, and in Xuchotl we shall die."
   "Well," said Conan, "with your leave we'll take our chances with the dragons. This feud is none of our business. If you'll show us to the west gate we'll be on our way."
   Tascela's hands clenched, and she started to speak, but Olmec interrupted her: "It is nearly nightfall. If you wander forth into the plain by night, you will certainly fall prey to the dragons."
   "We crossed it last night, and slept in the open without seeing any," returned Conan.
   Tascela smiled mirthlessly. "You dare not leave Xuchotl!"
   Conan glared at her with instinctive antagonism; she was not looking at him, but at the woman opposite him.
   "I think they dare," stated Olmec. "But look you, Conan and Valeria, the gods must have sent you to us, to cast victory into the laps of the Tecuhltli! You are professional fighters—why not fight for us? We have wealth in abundance—precious jewels are as common in Xuchotl as cobblestones are in the cities of the world. Some the Xuchotlans brought with them from Kosala. Some, like the firestones, they found in the hills to the east. Aid us to wipe out the Xotalancas, and we will give you all the jewels you can carry."
   "And will you help us destroy the dragons?" asked Valeria. "With bows and poisoned arrows thirty men could slay all the dragons in the forest."
   "Aye!" replied Olmec promptly. "We have forgotten the use of the bow, in years of hand-to-hand fighting, but we can learn again."
   "What do you say?" Valeria inquired of Conan.
   "We're both penniless vagabonds," he grinned hardily. "I'd as soon kill Xotalancas as anybody."
   "Then you agree?" exclaimed Olmec, while Techotl fairly hugged himself with delight.
   "Aye. And now suppose you show us chambers where we can sleep, so we can be fresh tomorrow for the beginning of the slaying."
   Olmec nodded, and waved a hand, and Techotl and a woman led the adventurers into a corridor which led through a door off to the left of the jade dais. A glance back showed Valeria Olmec sitting on his throne, chin on knotted fist, staring after them. His eyes burned with a weird flame. Tascela leaned back in her seat, whispering to the sullen-faced maid, Yasala, who leaned over her shoulder, her ear to the princess's moving lips.
   The hallway was not so broad as most they had traversed, but it was long. Presently the woman halted, opened a door, and drew aside for Valeria to enter.
   "Wait a minute," growled Conan. "Where do I sleep?"
   Techotl pointed to a chamber across the hallway, but one door farther down. Conan hesitated, and seemed inclined to raise an objection, but Valeria smiled spitefully at him and shut the door in his face. He muttered soemthing uncomplimentary about women in general, and strode off down the corridor after Techotl.
   In the ornate chamber where he was to sleep, he glanced up at the slot-like skylights. Some were wide enough to admit the body of a slender man, supposing the glass were broken.
   "Why don't the Xotalancas come over the roofs and shatter those skylights?" he asked.
   "They cannot be broken," answered Techotl. "Besides, the roofs would be hard to clamber over. They are mostly spires and domes and steep ridges."
   He volunteered more information about the "castle" of Tecuhltli. Like the rest of the city it contained four stories, or tiers of chambers, with towers jutting up from the roof. Each tier was named; indeed, the people fo Xuchotl had a name for each chamber, hall, and stair in the city, as people of more normal cities designate streets and quarters. In Tecuhltli the floors were named The Eagle's Tier, The Ape's Tier, The Tiger's Tier and The Serpent's Tier, in the order as enumerated, The Eagle's Tier being the highest, or fourth, floor.
   "Who is Tascela?" asked Conan. "Olmec's wife?"
   Techotl shuddered and glanced furtively about him before answering.
   "No. She is—Tascela! She was the wife of Xotalanc—the woman Tecuhltli stole, to start the feud."
   "What are you talking about?" demanded Conan. "That woman is beautiful and young. Are you trying to tell me that she was a wife fifty years ago?"
   "Aye! I swear it! She was a full-grown woman when the Tlazitlans journeyed from Lake Zuad. It was because the king of Stygia desired her for a concubine that Xotalanc and his brother rebelled and fled into the wilderness. She is a witch, who possesses the secret of perpetual youth."
   "What's that?" asked Conan.
   Techotl shuddered again.
   "Ask me not! I dare not speak. It is too grisly, even for Xuchotl!"
   And touching his finger to his lips, he glided from the chamber.

4. Scent of Black Lotus

   Valeria unbuckled her sword belt and laid it with the sheathed weapon on the couch where she meant to sleep. She noted that the doors were supplied with bolts, and asked where they led.
   "Those lead to adjoining chambers," answered the woman, indicating the doors on right and left. "That one?"—pointing to a copper-bound door opposite that which opened into the corridor—"leads to a corridor which runs to a stair that descends into the catacombs. Do not fear; naught can harm you here."
   "Who spoke of fear?" snapped Valeria. "I just like to know what sort of harbor I'm dropping anchor in. No, I don't want you to sleep at the foot of my couch. I'm not accustomed to being waited on—not by women, anyway. You have my leave to go."
   Alone in the room, the pirate shot the bolts on all the doors, kicked off her boots and stretched luxuriously out on the couch. She imagined Conan similarly situated across the corridor, but her feminine vanity prompted her to visualize him as scowling and muttering with chagrin as he cast himself on his solitary couch, and she grinned with gleeful malice as she prepared herself for slumber.
   Outside, night had fallen. In the halls of Xuchotl the green fire-jewels blazed like the eyes of prehistoric cats. Somewhere among the dark towers, a night wind moaned like a restless spirit. Through the dim passages, stealthy figures began stealing, like disembodied shadows.
   Valeria awoke suddenly on her couch. In the dusky emerald glow of the fire-gems she saw a shadowy figure bending over her. For a bemused instant the apparition seemed part of the dream she had been dreaming. She had seemed to lie on the couch in the chamber as she was actually lying, while over her pulsed and throbbed a gigantic black blossom so enormous that it hid the ceiling. Its exotic perfume pervaded her being, inducing a delicious, sensuous languor that was something more and less than sleep. She was sinking into scented billows of insensible bliss, when something touched her face. So supersensitive were her drugged senses, that the light touch was like a dislocating impact, jolting her rudely into full wakefulness. Then it was that she saw, not a gargantuan blossom, but a dark-skinned woman standing above her.
   With the realization came anger and instant action. The woman turned lithely, but before she could run Valeria was on her feet and had caught her arm. She fought like a wildcat for an instant, and then subsided as she felt herself crushed by the superior strength of her captor. The priate wrenched the woman around to face her, caught her chin with her free hand and forced her captive to meet her gaze. It was the sullen Yasala, Tascela's maid.
   "What the devil were you doing bending over me? What's that in your hand?"
   The woman made no reply, but sought to cast away the object. Valeria twisted her arm around in front of her, and the thing fell to the floor—a great black exotic blossom on a jade-green stem, large as a woman's head, to be sure, but tiny beside the exaggerated vision she had seen.
   "The black lotus!" said Valeria between her teeth. "The blossom whose scent brings deep sleep. You were trying to drug me! If you hadn't accidentally touched my face with the petals, you'd have—why did you do it? What's your game?"
   Yasala maintained a sulky silence, and with an oath Valeria whirled her around, forced her to her knees and twisted her arm up behind her back.
   "Tell me, or I'll tear your arm out of its socket!"
   Yasala squirmed in anguish as her arm was forced excruciatingly up between her shoulder blades, but a violent shaking of her head was the only answer she made.
   "Slut!" Valeria cast her from her to sprawl on the floor. The pirate glared at the prostrate figure with blazing eyes. Fear and the memory of Tascela's burning eyes stirred in her, rousing all her tigerish instincts of self-preservation. These people were decadent; any sort of perversity might be expected to be encountered among them. But Valeria sensed here something that moved behind the scenes, some secret terror fouler than common degeneracy. Fear and revulsion of this weird city swept her. These people were neither sane nor normal; she began to doubt if they were even human. Madness smoldered in the eyes of them all—all except the cruel, cryptic eyes of Tascela, which held secrets and mysteries more abysmal than madness.
   She lifted her head and listened intently. The halls of Xuchotl were as silent as if it were in reality a dead city. The green jewels bathed the chamber in a nightmare glow, in which the eyes of the woman on the floor glittered eerily up at her. A thrill of panic throbbed through Valeria, driving the last vestige of mercy from her fierce soul.
   "Why did you try to drug me?" she muttered, grasping the woman's black hair, and forcing her head back to glare into her sullen, long-lashed eyes. "Did Tascela send you?"
   No answer. Valeria cursed venomously and slapped the woman first on one cheek and then the other. The blows resounded through the room, but Yasala made no outcry.
   "Why don't you scream?" demanded Valeria savagely. "Do you fear someone will hear you? Whom do you fear? Tascela? Olmec? Conan?"
   Yasala made no reply. She crouched, watching her captor with eyes baleful as those of a basilisk. Stubborn silence always fans anger. Valeria turned and tore a handful of cords from a near-by hanging.
   "You sulky slut!" she said between her teeth. "I'm going to strip you stark naked and tie you across that couch and whip you until you tell me what you were doing here, and who sent you!"
   Yasala made no verbal protest, nor did she offer any resistance, as Valeria carried out the first part of her thereat with a fury that her captive's obstinacy only sharpened. Then for a space there was no sound in the chamber except the whistle and crackle of hard-woven silken cords on naked flesh. Yasala could not move her fast-bound hands or feet. Her body writhed and quivered under the chastisement, her head swayed from side to side in rhythm with the blows. Her teeth were sunk into her lower lip and a trickle of blood began as the punishment continued. But she did not cry out.
   The pliant cords made no great sound as they encountered the quivering body of the captive; only a sharp crackling snap, but each cord left a red streak across Yasala's dark flesh. Valeria inflicted the punishment with all the strength of her war-hardened arm, with all the mercilessness acquired during a life where pain and torment were daily happenings, and with all the cynical ingenuity which only a woman displays toward a woman. Yasala suffered more, physically and mentally, than she would have suffered under a lash wielded by a man, however strong.
   It was the application of this feminine cynicism which at last tamed Yasala.
   A low whimper escaped from her lips, and Valeria paused, arm lifted, and raked back a damp yellow lock. "Well, are you going to talk?" she demanded. "I can keep this up all night, if necessary."
   "Mercy!" whispered the woman. "I will tell."
   Valeria cut the cords from her wrists and ankles, and pulled her to her feet. Yasala sank down on the couch, half reclining on one bare hip, supporting herself on her arm, and writhing at the contact of her smarting flesh with the couch. She was trembling in every limb.
   "Wine!" she begged, dry-lipped, indicating with a quivering hand a gold vessel on an ivory table. "Let me drink. I am weak with pain. Then I will tell you all."
   Valeria picked up the vessel, and Yasala rose unsteadily to receive it. She took it, raised it toward her lips—then dashed the contents full into the Aquilonian's face. Valeria reeled backward, shaking and clawing the stinging liquid out of her eyes. Through a smarting mist she saw Yasala dart across the room, fling back a bolt, throw open the copperbound door and run down the hall. The pirate was after her instantly, sword out and murder in her heart.
   But Yasala had the start, and she ran with the nervous agility of a woman who has just been whipped to the point of hysterical frenzy. She rounded a corner in the corridor, yards ahead of Valeria, and when the pirate turned it, she saw only an empty hall, and at the other end a door that gaped blackly. A damp moldy scent reeked up from it, and Valeria shivered. That must be the door that hed to the catacombs. Yasala had taken refuge among the dead.
   Valeria advanced to the door and looked down a flight of stone steps that vanished quickly into utter blackness. Evidently it was a shaft that led straight to the pits below the city, without opening upon any of the lower floors. She shivered slightly at the thought of the thousands of corpses lying in their stone cypts down there, wrapped in their moldering cloths. She had no intention of groping her way down those stone steps. Yasala doubtless knew every turn and twist of the subterranean tunnels.
   She was turning back, baffled and furious, when a sobbing cry welled up from the blackness. It seemed to come from a great depth, but human words were faintly distinguishable, and the voice was that of a woman. "Oh, help! Help, in Set's name! Ahhh!" It trailed away, and Valeria thought she caught the echo of a ghostly tittering.
   Valeria felt her skin crawl. What had happened to Yasala down there in the thick blackness? There was no doubt that it had been she who had cried out. But what peril could have befallen her? Was a Xotalanca lurking down there? Olmec had assured them that the catacombs below Tecuhltli were walled off from the rest, too securely for their enemies to break through. Besides, that tittering had not sounded like a human being at all.
   Valeria hurried back down the corridor, not stopping to close the door that opened on the stair. Regaining her chamber, she closed the door and shot the bolt behind her. She pulled on her boots and buckled her sword-belt about her. She was determined to make her way to Conan's room and urge him, if he still lived, to join her in an attampt to fight their way out of that city of devils.
   But even as she reached the door that opened into the corridor, a long-drawn scream of agony rang through the halls, followed by the stamp of running feet and the loud clangor of swords.

5. Twenty Red Nails

   Two warriors lounged in the guardroom on the floor known as the Tier of the Eagle. Their attitude was casual, though habitually alert. An attack on the great bronze door from without was always a possibility, but for many years no such assault had been attempted on either side.
   "The strangers are strong allies," said one. "Olmec will move against the enemy tomorrow, I believe."
   He spoke as a soldier in a war might have spoken. In the miniature world of Xuchotl each handful of feudists was an army, and the empty halls between the castles was the country over which they campaigned.
   The other meditated for a space.
   "Suppose with their aid we destroy Xotalanc," he said. "What then, Xatmec?"
   "Why," returned Xatmec, "we will drive red nails for them all. The captives we will burn and flay and quarter."
   "But afterward?" pursued the other. "After we have slain them all? Will it not seem strange to have no foe to fight? All my life I have fought and hated the Xotalancas. With the feud ended, what is left?"
   Xatmec shrugged his shoulders. His thoughts had never gone beyond the destruction of their foes. They could not go beyond that.
   Suddenly both men stiffened at a noise outside the door.
   "To the door, Xatmec!" hissed the last speaker. "I shall look through the Eye—"
   Xatmec, sword in hand, leaned against the bronze door, straining his ear to hear through the metal. His mate looked into the mirror. He started convulsively. Men were clustered thickly outside the door; grim, dark-faced men with swords gripped in their teeth—and their fingers thrust into their ears. One who wore a feathered headdress had a set of pipes whch he set to his lips, and even as the Tecuhltli started to shout a warning, the pipes began to skirl.
   The cry died in the guard's throat as the thin, weird piping penetrated the metal door and smote on his ears. Xatmec leaned frozen against the door, as if paralyzed in that position. His face was that of a wooden image, his expression one of horrified listening. The other guard, farther removed from the source of the sound, yet sensed the horror of what was taking place, the grisly threat that lay in that demoniac fifing. He felt the weird strains plucking like unseen fingers at the tissues of his brain, filling him with alien emotions and impulses of madness. But with a soul-tearing effort he broke the spell, and shrieked a warning in a voice he did not recognize as his own.
   But even as he cried out, the music changed to an unbearable shrilling that was like a knife in the eardrums. Xatmec screamed in sudden agony, and all the sanity went out of his face like a flame blown out in a wind. Like a madman he ripped loose the chain, tore open the door and rushed out into the hall, sword lifted before his mate could stop him. A dozen blades struck him down, and over his mangled body the Xotalancas surged into the guardroom, with a long-drawn, blood-mad yell that sent the unwonted echoes reverberating.
   His brain reeling from the shock of it all, the remaining guard leaped to meet them with goring spear. The horror of the sorcery he had just witnessed was submerged in the stunning realization that the enemy were in Tecuhltli. And as his spearhead ripped through a dark-skinned belly he knew no more, for a swinging sword crushed his skull, even as wild-eyed warriors came pouring in from the chambers behind the guardroom.
   It was the yelling of men and the clanging of steel that brought Conan bounding from his couch, wide awake and broadsword in hand. In an instant he had reached the door and flung it open, and was glaring out into the corridor just as Techotl rushed up it, eyes blazing madly.
   "The Xotalancas!" he screamed, in a voice hardly human. "They are within the door!"
   Conan ran down the corridor, even as Valeria emerged from her chamber.
   "What the devil is it?" she called.
   "Techotl says the Xotalancas are in," he answered hurriedly. "That racket sounds like it."
   With the Tecuhltli on their heels they burst into the throne room and were confronted by a scene beyond the most frantic dream of blood and fury. Twenty men and women, their black hair streaming, and the white skulls gleaming on their breasts, were locked in combat with the people of Tecuhltli. The women on both sides fought as madly as the men, and already the room and the hall beyond were strewn with corpses.
   Olmec, naked but for a breech-clout, was fighting before his throne, and as the adventurers entered, Tascela ran from an inner chamber with a sword in her hand.
   Xatmec and his mate were dead, so there was none to tell the Tecuhltli how their foes had found their way into their citadel. Nor was there any to say what had prompted that mad attempt. But the losses of the Xotalancas had been greater, their position more desperate, than the Tecuhltli had known. The maiming of their scaly ally, the destruction of the Burning Skull, and the news, gasped by a dying man, that mysterious white-skin allies had joined their enemies, had driven them to the frenzy of desperation and the wild determination to die dealing death to their ancient foes.
   The Tecuhltli, recovering from the first stunning shock of the surprise that had swept them back into the throne room and littered the floor with their corpses, fought back with an equally desperate fury, while the doorguards from the lower floors came racing to hurl themselves into the fray. It was the deathfight of rabid wolves, blind, panting, merciless. Back and forth it surged, from door to dais, blades whickering and striking into flesh, blood spurting, feet stamping the crimson floor where redder pools were forming. Ivory tables crashed over, seats were splintered, velvet hangings torn down were stained red. It was the bloody climax of a bloody half-century, and every man there sensed it.
   But the conclusion was inevitable. The Tecuhltli outnumbered the invaders almost two to one, and they were heartened by that fact and by the entrance into the melee of their light-skinned allies.
   These crashed into the fray with the devastating effect of a hurricane plowing through a grove of saplings. In sheer strength no three Tlazitlans were a match for Conan, and in spite of his weight he was quicker on his feet than any of them. He moved through the whirling, eddying mass with the surety and destructiveness of a gray wolf amidst a pack of alley curs, and he strode over a wake of crumpled figures.
   Valeria fought beside him, her lips smiling and her eyes blazing. She was stronger than the average man, and far quicker and more ferocious. Her sword was like a living thing in her hand. Where Conan beat down opposition by the sheer weight and power of his blows, breaking spears, splitting skulls and cleaving bosoms to the breastbone, Valeria brought into action a finesse of swordplay that dazzled and bewildered her antagonists before it slew them. Again and again a warrior, heaving high his heavy blade, found her point in his jugular before he could strike. Conan, towering above the field, strode through the welter smiting right and left, but Valeria moved like an illusive phantom, constantly shifting, and thrusting and slashing as she shifted. Swords missed her again and again as the wielders flailed the empty air and died with her point in their hearts or throats, and her mocking laughter in their ears.
   Neither sex nor condition was considered by the maddened combatants. The five women of the Xotalancas were down with thir throats cut before Conan and Valeria entered the fray, and when a man or woman went down under the stamping feet, there was always a knife ready for the helpless throat, or a sandaled foot eager to crush the prostrate skull.
   From wall to wall, from door to door rolled the waves of combat, spilling over into adjoining chambers. And presently only Tecuhltli and their white-skinned allies stood upright in the great throne room. The survivors stared bleakly and blankly at each other, like survivors after Judgement Day or the destruction of the world. On legs wide-braced, hands gripping notched and dripping swords, blood trickling down their arms, they stared at one another across the mangled corpses of friends and foes. They had no breath left to shout, but a bestial mad howling rose from their lips. It was not a human cry of triumph. It was the howling of a rabid wolf-pack stalking among the bodies of its victims.
   Conan caught Valeria's arm and turned her about.
   "You've got a stab in the calf of your leg," he growled.
   She glanced down, for the first time aware of a stinging in the muscles of her leg. Some dying man on the floor had fleshed his dagger with his last effort.
   "You look like a butcher yourself," she laughed.
   He shook a red shower from his hands.
   "Not mine. Oh, a scratch here and there. Nothing to bother about. But that calf ought to be bandaged."
   Olmec came through the litter, looking like a ghoul with his naked massive shoulders splashed with blood, and his black beard dabbled in crimson. His eyes were red, like the reflection of flame on black water.
   "We have won!" he croaked dazedly. "The feud is ended! The dogs of Xotalanc lie dead! Oh, for a captive to flay alive! Yet it is good to look upon their dead faces. Twenty dead dogs! Twenty red nails for the black column!"
   "You'd best see to your wounded," grunted Conan, turning away from him. "Here, girl, let me see that leg."
   "Wait a minute!" she shook him off impatiently. The fire of fighting still burned brightly in her soul. "How do we know these are all of them? These might have come on a raid of their own."
   "They would not split the clan on a foray like this," said Olmec, shaking his head, and regaining some of his ordinary intelligence. Without his purple robe the man seemed less like a prince than some repellent beast of prey. "I will stake my head upon it that we have slain them all. There were less of them than I dreamed, and they must have been desperate. But how came they in Tecuhltli?"
   Tascela came forward, wiping her sword on her naked thigh, and holding in her other hand an object she had taken from the body of the feathered leader of the Xotalancas.
   "The pipes of madness," she said. "A warrior tells me that Xatmec opened the door to the Xotalancas and was cut down as they stormed into the guardroom. This warrior came to the guardroom from the inner hall just in time to see it happen and to hear the last of a weird strain of music which froze his very soul. Tolkemec used to talk of these pipes, which the Xuchotlans swore were hidden somewhere in the catacombs with the bones of the ancient wizard who used them in his lifetime. Somehow the dogs of Xotalanc found them and learned their secret."
   "Somebody ought to go to Xotalanc and see if any remain alive," said Conan. "I'll go if somebody will guide me."
   Olmec glanced at the remnants of his people. There were only twenty left alive, and of these several lay groaning on the floor. Tascela was the only one of the Tecuhltli who had escaped without a wound. The princess was untouched, though she had fought as savagely as any.
   "Who will go with Conan to Xotalanc?" asked Olmec.
   Techotl limped forward. The wound in his thigh had started bleeding afresh, and he had another gash across his ribs.
   "I will go!"
   "No, you won't," vetoed Conan. "And you're not going either, Valeria. In a little while that leg will be getting stiff."
   "I will go," volunteered a warrior, who was knotting a bandage about a slashed forearm.
   "Very well, Yanath. Go with the Cimmerian. And you, too, Topal." Olmec indicated another man whose injuries were slight. "But first aid to lift the badly wounded on these couches where we may bandage their hurts."
   This was done quickly. As they stooped to pick up a woman who had been stunned by a warclub, Olmec's beard brushed Topal's ear. Conan thought the prince muttered something to the warrior, but he could not be sure. A few moments later he was leading his companions down the hall.
   Conan glanced back as he went out the door, at that shambles where the dead lay on the smoldering floor, blood-stained dark limbs knotted in attitudes of fierce muscular effort, dark faces frozen in masks of hate, glassy eyes glaring up at the green fire-jewels which bathed the ghastly scene in a dusky emerald witchlight. Among the dead the living moved aimlessly, like people moving in a trance. Conan heard Olmec call a woman and direct her to bandage Valeria's leg. The pirate followed the woman into an adjoining chamber, already beginning to limp slightly.
   Warily the two Tecuhltli led Conan along the hall beyond the bronze door, and through chamber after chamber shimmering in the green fire. They saw no one, heard no sound. After they crossed the Great Hall which bisected the city from north to south, their caution was increased by the realization of their nearness to enemy territory. But chambers and halls lay empty to their wary gaze, and they came at last along a broad dim hallway and halted before a bronze door similar to the Eagle Door of Tecuhltli. Gingerly they tried it, and it opened at silently under their fingers. Awed, they started into the green-lit chambers beyond. For fifty years no Tecuhltli had entered those halls save as a prisoner going to a hideous doom. To go to Xotalanc had been the ultimate horror that could befall a man of the western castle. The terror of it had stalked through their dreams since earliest childhood. To Yanath and Topol that bronze door was like the portal of hell.
   They cringed back, unreasoning horror in their eyes, and Conan pushed past them and strode into Xotalanc.
   Timidly they followed him. As each man set foot over the threshold he stared and glared wildly about him. But only their quick, hurried breathing disturbed the silence.
   They had come into a square guardroom, like that behind the Eagle Door of Tecuhltli, and, similarly, a hall ran away from it to a broad chamber that was a counterpart of Olmec's throne room.
   Conan glanced down the hall with its rugs and divans and hangings, and stood listening intently. He heard no noise, and the rooms had an empty feel. He did not believe there were any Xotalancas left alive in Xuchotl.
   "Come on," he muttered, and started down the hall.
   He had not gone far when he was aware that only Yanath was following him. He wheeled back to see Topal standing in an attitude of horror, one arm out as if to fend off some threatening peril, his distended eyes fixed with hypnotic intensity on something protruding from behind a divan.
   "What the devil?" Then Conan saw what Topal was staring at, and he felt a faint twitching of the skin between his giant shoulders. A monstrous head protruded from behind the divan, a reptilian head, broad as the head of a crocodile, with down-curving fangs that projected over the lower jaw. But there was an unnatural limpness about the thing, and the hideous eyes were glazed.
   Conan peered behind the couch. It was a great serpent which lay there limp in death, but such a serpent as he had never seen in his wanderings. The reek and chill of the deep black earth were about it, and its color was an indeterminable hue which changed with each new angle from which he surveyed it. A great wound in the neck showed what had caused its death.
   "It is the Crawler!" whispered Yanath.
   "It's the thing I slashed on the stair," grunted Conan. "After it trailed us to the Eagle Door, it dragged itself here to die. How could the Xotalancas control such a brute?"
   The Tecuhltli shivered and shook their heads.
   "They brought it up from the black tunnels below the catacombs. They discovered secrets unknown to Tecuhltli."
   "Well, it's dead, and if they'd had any more of them, they'd have brought them along when they came to Tecuhltli. Come on."
   They crowded close at his heels as he strode down the hall and thrust on the silver-worked door at the other end.
   "If we don't find anybody on this floor," he said, "we'll descend into the lower floors. We'll explore Xotalanc from the roof to the catacombs. If Xotalanc is like Tecuhltli, all the rooms and halls in this tier will be lighted—what the devil!"
   They had come into the broad throne chamber, so similar to that one in Tecuhltli. There were the same jade dais and ivory seat, the same divans, rugs and hangings on the walls. No black, red-scarred column stood behind the throne-dais, but evidences of the grim feud were not lacking.
   Ranged along the wall behind the dais were rows of glass-covered shelves. And on those shelves hundreds of human heads, perfectly preserved, stared at the startled watchers with emotionless eyes, as they had stared for only the gods knew how many months and years.
   Topal muttered a curse, but Yanath stood silent, the mad light growing in his wide eyes. Conan frowned, knowing that Tlazitlan sanity was hung on a hair-trigger.
   Suddenly Yanath pointed to the ghastly relics with a twitching finger.
   "There is my brother's head!" he murmured. "And there is my father's younger brother! And there beyond them is my sister's eldest son!"
   Suddenly he began to weep, dry-eyed, with harsh, loud sobs that shook his frame. He did not take his eyes from the heads. His sobs grew shriller, changed to frightful, high-pitched laughter, and that in turn became an unbearable screaming. Yanath was stark mad.
   Conan laid a hand on his shoulder, and as if the touch had released all the frenzy in his soul, Yanath screamed and whirled, striking at the Cimmerian with his sword. Conan parried the blow, and Topal tried to catch Yanath's arm. But the madman avoided him and with froth flying from his lips, he drove his sword deep into Topal's body. Topal sank down with a groan, and Yanath whirled for an instant like a crazy dervish; then he ran at the shelves and began hacking at the glass with his sword, screeching blasphemously.
   Conan sprang at him from behind, trying to catch him unaware and disarm him, but the madman wheeled and lunged at him, screaming like a lost soul. Realizing that the warrior was hopelessly insane, the Cimmerian side-stepped, and as the maniac went past, he swung a cut that severed the shoulder-bone and breast, and dropped the man dead beside his dying victim.
