With a grunt the Cimmerian turned and strode across the chamber to the opposite door, with a feeling of treading on the threshold of doom. As he lifted his knife to shatter the door, it swung silently open as if of its own accord. He strode into the great hall, flanked with tall glassy columns. A hundred feet from the door began the broad jade-green steps of a stair that tapered toward the top like the side of a pyramid. What lay beyond that stair he could not tell. But between him and its shimmering foot stood a curious altar of gleaming black jade. Four great golden serpents twined their tails about this altar and reared their wedge-shaped heads in the air, facing the four quarters of the compass like the enchanted guardians of a fabled treasure. But on the altar, between the arching necks, stood only a crystal globe filled with a cloudy smoke-like substance, in which floated four golden pomegranates. The sight stirred some dim recollection in his mind; then Conan heeded the altar no longer, for on the lower steps of the stair stood four black-robed figures. He had not seen them come. They were simply there, tall, gaunt, their vulture-heads nodding in unison, their feet and hands hidden by their flowing garments. One lifted his arm and the sleeve fell away revealing his hand--and it was not a hand at all. Conan halted in mid-stride, compelled against his will. He had encountered a force differing subtly from Khemsa's mesmerism, and he could not advance, though he felt it in his power to retreat if he wished. His companions had likewise halted, and they seemed even more helpless than he, unable to move in either direction. The seer whose arm was lifted beckoned to one of the Irakzai, and the man moved toward him like one in a trance, eyes staring and fixed, blade hanging in limp fingers. As he pushed past Conan, the Cimmerian threw an arm across his breast to arrest him. Conan was so much stronger than the Irakzai that in ordinary circumstances he could have broken his spine between his hands. But now the muscular arm was brushed aside like straw and the Irakzai moved toward the stair, treading jerkily and mechanically. He reached the steps and knelt stiffly, proffering his blade and bending his head. The Seer took the sword. It flashed as he swung it up and down. The Irakzai's head tumbled from his shoulders and thudded heavily on the black marble floor. An arch of blood jetted from the severed arteries and the body slumped over and lay with arms spread wide. 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.
