Techotl went ashy again and attacked the door with his fists, screaming: "Open, you fools, open! The Crawler is at our heels!" Even as he beat and shouted, the great bronze door swung noiselessly back, revealing a heavy chain across the entrance, over which spear-heads bristled and fierce countenances regarded them intently for an instant. Then the chain was dropped and Techotl grasped the arms of his friends in a nervous frenzy and fairly dragged them over the threshold. A glance over his shoulder just as the door was closing showed Conan the long dim vista of the hall, and dimly framed at the other end an ophidian shape that writhed slowly and painfully into view, flowing in a dull-hued length from a chamber door, its hideous blood-stained head wagging drunkenly. Then the closing door shut off the view. Inside the square chamber into which they had come heavy bolts were drawn across the door, and the chain locked into place. The door was made to stand the battering of a siege. Four men stood on guard, of the same lank-haired, dark-skinned breed as Techotl, with spears in their hands and swords at their hips. In the wall near the door there was a complicated contrivance of mirrors which Conan guessed was the Eye Techotl had mentioned, so arranged that a narrow, crystal-paned slot in the wall could be looked through from within without being discernible from without. The four guardsmen stared at the strangers with wonder, but asked no question, nor did Techotl vouchsafe any information. He moved with easy confidence now, as if he had shed his cloak of indecision and fear the instant he crossed the threshold. "Come!" he urged his new-found friends, but Conan glanced toward the door. "What about those fellows who were following us? Won't they try to storm that door?" Techotl shook his head. "They know they cannot break down the Door of the Eagle. They will flee back to Xotalanc, with their crawling fiend. Come! I will take you to the rulers of Tecuhltli." * * * * * One of the four guards opened the door opposite the one by which they had entered, and they passed through into a hallway which, like most of the rooms on that level, was lighted by both the slot-like skylights and the clusters of winking fire-gems. But unlike the other rooms they had traversed, this hall showed evidences of occupation. Velvet tapestries adorned the glossy jade walls, rich rugs were on the crimson floors, and the ivory seats, benches and divans were littered with satin cushions. The hall ended in an ornate door, before which stood no guard. Without ceremony Techotl thrust the door open and ushered his friends into a broad chamber, where some thirty dark-skinned men and women lounging on satin-covered couches sprang up with exclamations of amazement.
