a jet of blue lightning. The cry of the warrior broke short and he went down like an ox beneath the pole-ax, his brains gushing from his skull that had been split to the throat.
“Conan!” gasped Valeria. In a gust of passion she turned on the Xotalanc whose long hair she still gripped in her left hand. “Dog of hell!” Her blade swished as it cut the air in an upswinging arc with a blur in the middle, and the headless body slumped down, spurting blood. She hurled the severed head across the room.
“What the devil’s going on here?” Conan bestrode the corpse of the man he had killed, broadsword in hand, glaring about him in amazement.
Techotl was rising from the twitching figure of the last Xotalanc, shaking red drops from his dagger. He was bleeding from the stab deep in the thigh. He stared at Conan with dilated eyes.
“What is all this?” Conan demanded again, not yet recovered from the stunning surprise of finding Valeria engaged in a savage battle with these fantastic figures in a city he had thought empty and uninhabited. Returning from an aimless exploration of the upper chambers to find Valeria missing from the room where he had left her, he had followed the sounds of strife that burst on his dumbfounded ears.
“Five dead dogs!” exclaimed Techotl, his flaming eyes reflecting a ghastly exultation. “Five slain! Five crimson nails for the black pillar! The gods of blood be thanked!”
He lifted quivering hands on high, and then, with the face of a fiend, he spat on the corpses and stamped on their faces, dancing in his ghoulish glee. His recent allies eyed him in amazement, and Conan asked, in the Aquilonian tongue: “Who is this madman?”
Valeria shrugged her shoulders.
“He says his name’s Techotl. From his babblings I gather that his people live at one end of this crazy city, and these others at the other end. Maybe we’d better go with him. He seems friendly, and it’s easy to see that the other clan isn’t.”
Techotl had ceased his dancing and was listening again, his head tilted sidewise, dog-like, triumph struggling with fear in his repellent countenance.
“Come away, now!” he whispered. “We have done enough! Five dead dogs! My people will welcome you! They will honor you! But come! It is far to Tecuhltli. At any moment the Xotalancas may come on us in numbers too great even for your swords.”
“Lead the way,” grunted Conan.
Techotl instantly mounted a stair leading up to the gallery, beckoning them to follow him, which they did, moving rapidly to keep on his heels. Having reached the gallery, he plunged into a door that opened toward the west, and hurried through chamber after chamber, each lighted by skylights or green fire-jewels.
“What sort of a place can this be?” muttered Valeria under her breath.
“Crom knows!” answered Conan. “I’ve seen his kind before, though. They live on the shores of Lake Zuad, near the border of Kush. They’re a sort of mongrel Stygians, mixed with another race that wandered into Stygia from the east some centuries ago and were absorbed by them. They’re called Tlazitlans. I’m willing to bet it wasn’t they who built this city, though.”
Techotl’s fear did not seem to diminish as they drew away from the chamber where the dead men lay. He kept twisting his head on his shoulder to listen for sounds of pursuit, and stared with burning intensity into every doorway they passed.
Valeria shivered in spite of herself. She feared no man. But the weird floor beneath her feet, the uncanny jewels over her head, dividing the lurking shadows among them, the stealth and terror of their guide, impressed her with a nameless apprehension, a sensation of lurking, inhuman peril.
“They may be between us and Tecuhltli!” he whispered once. “We must beware lest they be lying in wait!”
“Why don’t we get out of this infernal palace, and take to the streets?” demanded Valeria.
“There are no streets in Xuchotl,” he answered. “No squares nor open courts. The whole city is built like one giant palace under one great roof. The nearest approach to a street is the Great Hall which traverses the city from the north gate to the south gate. The only doors opening into the outer world are the city gates, through which no living man has passed for fifty years.”
“How long have you dwelt here?” asked Conan.
“I was born in the castle of Tecuhltli thirty-five years ago. I have never set foot outside the city. For the love of the gods, let us go silently! These halls may be full of lurking devils. Olmec shall tell you all when we reach Tecuhltli.”
So in silence they glided on with the green fire-stones blinking overhead and the flaming floors smoldering under their feet, and it seemed to Valeria as if they fled through hell, guided by a dark-faced, lank-haired goblin.
Yet it was Conan who halted them as they were crossing an unusually wide chamber. His wilderness-bred ears were keener even than the ears of Techotl, whetted though these were by a lifetime of warfare in those silent corridors.
“You think some of your enemies may be ahead of us, lying in ambush?”
“They prowl through these rooms at all hours,” answered Techotl, “as do we. The halls and chambers between Tecuhltli and Xotalanc are a disputed region, owned by no man. We call it the Halls of Silence. Why do you ask?”
“Because men are in the chambers ahead of us,” answered Conan. “I heard steel clink against stone.”
Again a shaking seized Techotl, and he clenched his teeth to keep them from chattering.
“Perhaps they are your friends,” suggested Valeria.
“We dare not chance it,” he panted, and moved with frenzied activity. He turned aside and glided through a doorway on the left which led into a chamber from which an ivory staircase wound down into darkness.
“This leads to an unlighted corridor below us!” he hissed, great beads of perspiration standing out on his brow. “They may be lurking there, too. It may all be a trick to draw us into it. But we must take the chance that they have laid their ambush in the rooms above. Come swiftly, now!”
Softly as phantoms they descended the stair and came to the mouth of a corridor black as night. They crouched there for a moment, listening, and then melted into it. As they moved along, Valeria’s flesh crawled between her shoulders in momentary expectation of a sword-thrust in the dark. But for Conan’s iron fingers gripping her arm she had no physical cognizance of her companions. Neither made as much noise as a cat would have made. The darkness was absolute. One hand, outstretched, touched a wall, and occasionally she felt a door under her fingers. The hallway seemed interminable.
Suddenly they were galvanized by a sound behind them. Valeria’s flesh crawled anew, for she recognized it as the soft opening of a door. Men had come into the corridor behind them. Even with the thought she stumbled over something that felt like a human skull. It rolled across the floor with an appalling clatter.
“Run!” yelped Techotl, a note of hysteria in his voice, and was away down the corridor like a flying ghost.
Again Valeria felt Conan’s hand bearing her up and sweeping her along as they raced after their guide. Conan could see in the dark no better than she, but he possessed a sort of instinct that made his course unerring. Without his support and guidance she would have fallen or stumbled against the wall. Down the corridor they sped, while the swift patter of flying feet drew closer and closer, and then suddenly Techotl panted: “Here is the stair! After me, quick! Oh, quick!”
His hand came out of the dark and caught Valeria’s wrist as she stumbled blindly on the steps. She felt herself half dragged, half lifted up the winding stair, while Conan released her and turned on the steps, his ears and instincts telling him their foes were hard at their backs. And the sounds were not all those of human feet.
Something came writhing up the steps, something that slithered and rustled and brought a chill in the air with it. Conan lashed down with his great sword and felt the blade
