Again a malformed hand lifted and beckoned, and another Irakzai stumbled stiffly to his doom. The ghastly drama was re-enacted and another headless form lay beside the first.
As the third tribesman clumped his way past Conan to his death, the Cimmerian, his veins bulging in his temples with his efforts to break past the unseen barrier that held him, was suddenly aware of allied forces, unseen, but waking into life about him. This realization came without warning, but so powerfully that he could not doubt his instinct. His left hand slid involuntarily under his Bakhariot belt and closed on the Stygian girdle. And as he gripped it he felt new strength flood his numbed limbs; the will to live was a pulsing white-hot fire, matched by the intensity of his burning rage.
The third Irakzai was a decapitated corpse, and the hideous finger was lifting again when Conan felt the bursting of the invisible barrier. A fierce, involuntary cry burst from his lips as he leaped with the explosive suddenness of pent-up ferocity. His left hand gripped the sorcerer's girdle as a drowning man grips a floating log, and the long knife was a sheen of light in his right. The men on the steps did not move. They watched calmly, cynically; if they felt surprise they did not show it. Conan did not allow himself to think what might chance when he came within knife-reach of them. His blood was pounding in his temples, a mist of crimson swam before his sight. He was afire with the urge to kill—to drive his knife deep into flesh and bone, and twist the blade in blood and entrails.
Another dozen strides would carry him to the steps where the sneering demons stood. He drew his breath deep, his fury rising redly as his charge gathered momentum. He was hurtling past the altar with its golden serpents when like a levin-flash there shot across his mind again as vividly as if spoken in his external ear, the cryptic words of Khemsa: 'Break the crystal ball!'
His reaction was almost without his own volition. Execution followed impulse so spontaneously that the greatest sorcerer of the age would not have had time to read his mind and prevent his action. Wheeling like a cat from his headlong charge, he brought his knife crashing down upon the crystal. Instantly the air vibrated with a peal of terror, whether from the stairs, the altar, or the crystal itself he could not tell. Hisses filled his ears as the golden serpents, suddenly vibrant with hideous life, writhed and smote at him. But he was fired to the speed of a maddened tiger. A whirl of steel sheared through the hideous trunks that waved toward him, and he smote the crystal sphere again and yet again. And the globe burst with a noise like a thunderclap, raining fiery shards on the black marble, and the gold pomegranates, as if released from captivity, shot upward toward the lofty roof and were gone.
A mad screaming, bestial and ghastly, was echoing through the great hall. On the steps writhed four black-robed figures, twisting in convulsions, froth dripping from their livid mouths. Then with one frenzied crescendo of inhuman ululation they stiffened and lay still, and Conan knew that they were dead. He stared down at the altar and the crystal shards. Four headless golden serpents still coiled about the altar, but no alien life now animated the dully gleaming metal.
Kerim Shah was rising slowly from his knees, whither he had been dashed by some unseen force. He shook his head to clear the ringing from his ears.
'Did you hear that crash when you struck? It was as if a thousand crystal panels shattered all over the castle as that globe burst. Were the souls of the wizards imprisoned in those golden balls?—Ha!'
Conan wheeled as Kerim Shah drew his sword and pointed.
Another figure stood at the head of the stair. His robe, too, was black, but of richly embroidered velvet, and there was a velvet cap on his head. His face was calm, and not unhandsome.
