"Do not touch it! Do not even look at it! Madness and death lurk in it. The wizards of Xotalanc understand its secret--they 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 dream--it 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.
