The crimson shape left the mountain slope and came down in a long arching sweep. It struck the ledge between Conan and Khemsa, and the Rakhsha gave back with a stifled cry. He backed away, pushing the girl Gitara back with groping, fending hands. The crimson cloud balanced like a spinning top for an instant, whirling in a dazzling sheen on its point. Then without warning it was gone, vanished as a bubble vanishes when burst. There on the ledge stood four men. It was miraculous, incredible, impossible, yet it was true. They were not ghosts or phantoms. They were four tall men, with shaven, vulture-like heads, and black robes that hid their feet. Their hands were concealed by their wide sleeves. They stood in silence, their naked heads nodding slightly in unison. They were facing Khemsa, but behind them Conan felt his own blood turning to ice in his veins. Rising, he backed stealthily away, until he could feel the stallion's shoulder trembling against his back, and the Devi crept into the shelter of his arm. There was no word spoken. Silence hung like a stifling pall. All four of the men in black robes stared at Khemsa. Their vulture-like faces were immobile, their eyes introspective and contemplative. But Khemsa shook like a man in an ague. His feet were braced on the rock, his calves straining as if in physical combat. Sweat ran in streams down his dark face. His right hand locked on something under his brown robe so desperately that the blood ebbed from that hand and left it white. His left hand fell on the shoulder of Gitara and clutched in agony like the grasp of a drowning man. She did not flinch or whimper, though his fingers dug like talons into her firm flesh. Conan had witnessed hundreds of battles in his wild life, but never one like this, wherein four diabolical wills sought to beat down one lesser but equally devilish will that opposed them. But he only faintly sensed the monstrous quality of that hideous struggle. With his back to the wall, driven to bay by his former masters, Khemsa was fighting for his life with all the dark power, all the frightful knowledge they had taught him through long, grim years of neophytism and vassalage. He was stronger than even he had guessed, and the free exercise of his powers in his own behalf had tapped unsuspected reservoirs of forces. And he was nerved to super-energy by frantic fear and desperation. He reeled before the merciless impact of those hypnotic eyes, but he held his ground. His features were distorted into a bestial grin of agony, and his limbs were twisted as on a rack. It was a war of souls, of frightful brains steeped in lore forbidden to men for a million years, of mentalities which had plumbed the abysses and explored the dark stars where spawn the shadows.
