The acolytes had reached the farther wall and were moving up it like great green flies. Letting himself upon the ramp, he descended warily. The rosy cloud lapped about his ankles, ascending as he lowered himself. It reached his knees, his thighs, his waist, his arm-pits. He felt as one feels a thick heavy fog on a damp night. With it lapping about his chin he hesitated, and then ducked under. Instantly his breath ceased; all air was shut off from him and he felt his ribs caving in on his vitals. With a frantic effort he heaved himself up, fighting for life. His head rose above the surface and he drank air in great gulps. Kerim Shah leaned down toward him, spoke to him, but Conan neither heard nor heeded. Stubbornly, his mind fixed on what the dying Khemsa had told him, the Cimmerian groped for the gold vein, and found that he had moved off it in his descent. Several series of hand-holds were niched in the ramp. Placing himself directly over the thread, he began climbing down once more. The rosy mist rose about him, engulfed him. Now his head was under, but he was still drinking pure air. Above him he saw his companions staring down at him, their features blurred by the haze that shimmered over his head. He gestured for them to follow, and went down swiftly, without waiting to see whether they complied or not. Kerim Shah sheathed his sword without comment and followed, and the Irakzai, more fearful of being left alone than of the terrors that might lurk below, scrambled after him. Each man clung to the golden thread as they saw the Cimmerian do. Down the slanting ramp they went to the ravine floor and moved out across the shining level, treading the gold vein like rope-walkers. It was as if they walked along an invisible tunnel through which air circulated freely. They felt death pressing in on them above and on either hand, but it did not touch them. The vein crawled up a similar ramp on the other wall up which the acolytes had disappeared, and up it they went with taut nerves, not knowing what might be waiting for them among the jutting spurs of rock that fanged the lip of the precipice. It was the green-robed acolytes who awaited them, with knives in their hands. Perhaps they had reached the limits to which they could retreat. Perhaps the Stygian girdle about Conan's waist could have told why their necromantic spells had proven so weak and so quickly exhausted. Perhaps it was knowledge of death decreed for failure that sent them leaping from among the rocks, eyes glaring and knives glittering, resorting in their desperation to material weapons. There among the rocky fangs on the precipice lip was no war of wizard craft. It was a whirl of blades, where real steel bit and real blood spurted, where sinewy arms dealt forthright blows that severed quivering flesh, and men went down to be trodden under foot as the fight raged over them.
