She reached down with her left hand and gripped his long hair, forcing his head back so that his white teeth and rolling eyes gleamed up at her. The tall Xotalanc cried out fiercely and leaped in, smiting with all the fury of his arm. Awkwardly she parried the stroke, and it beat the flat of her blade down on her head so that she saw sparks flash before her eyes, and staggered. Up went the sword again, with a low, beast-like cry of triumph--and then a giant form loomed behind the Xotalanc and steel flashed like a jet of blue lightning. The cry of the warrior broke short and he went down like an ox beneath the pole-ax, his brains gushing from his skull that had been split to the throat. "Conan!" gasped Valeria. In a gust of passion she turned on the Xotalanc whose long hair she still gripped in her left hand. "Dog of hell!" Her blade swished as it cut the air in an upswinging arc with a blur in the middle, and the headless body slumped down, spurting blood. She hurled the severed head across the room. "What the devil's going on here?" Conan bestrode the corpse of the man he had killed, broadsword in hand, glaring about him in amazement. Techotl was rising from the twitching figure of the last Xotalanc, shaking red drops from his dagger. He was bleeding from the stab deep in the thigh. He stared at Conan with dilated eyes. "What is all this?" Conan demanded again, not yet recovered from the stunning surprise of finding Valeria engaged in a savage battle with these fantastic figures in a city he had thought empty and uninhabited. Returning from an aimless exploration of the upper chambers to find Valeria missing from the room where he had left her, he had followed the sounds of strife that burst on his dumbfounded ears. "Five dead dogs!" exclaimed Techotl, his flaming eyes reflecting a ghastly exultation. "Five slain! Five crimson nails for the black pillar! The gods of blood be thanked!" He lifted quivering hands on high, and then, with the face of a fiend, he spat on the corpses and stamped on their faces, dancing in his ghoulish glee. His recent allies eyed him in amazement, and Conan asked, in the Aquilonian tongue: "Who is this madman?" Valeria shrugged her shoulders. "He says his name's Techotl. From his babblings I gather that his people live at one end of this crazy city, and these others at the other end. Maybe we'd better go with him. He seems friendly, and it's easy to see that the other clan isn't." * * * * * Techotl had ceased his dancing and was listening again, his head tilted sidewise, dog-like, triumph struggling with fear in his repellent countenance. "Come away, now!" he whispered. "We have done enough! Five dead dogs! My people will welcome you! They will honor you! But come! It is far to Tecuhltli. At any moment the Xotalancas may come on us in numbers too great even for your swords." "Lead the way," grunted Conan.
