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-eyes amazement at the whiteskinned 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 friendgoddess 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. "Whywhy, 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 secretthey 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 dreamit 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 near by"
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 side-stepped 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.
