Then, too, Conan realized what must have happened to him. His travels through this underground realm had taken him round in a circle. He had originally planned to emerge from the subterranean labyrinth under the Vestibule of the Gods. This grim gray edifice rose on the square of the temple pyramid, and in it the slaves and captives destined for sacrifice, including his own crew, were held.
Instead, the battle with the rats had driven him off his course, and his fall into the underground river had resulted in his being carried still farther away from his memorized route. But some whim of fate or of the gods had brought him around in a loop, returning him at length to the place he first meant to reach, or at least very near it.
The falling body, Conan was sure, was part of the exhausted surplus of the sacrifice, in which hearts were torn from living victims. The shaft down which the corpse had fallen probably extended up through the pyramid to an opening near the top. Therefore, he reasoned, he must be directly beneath the pyramid - or at least under the square surrounding it.
All this flashed through Conan's mind in the space of three heartbeats. As the monsters turned away from him, he dashed around the perimeter of the chamber to the vertical ladder, made of pegs driven into holes in the wall, which led from the floor of the cave up to the platform on which the Antillian guard was stationed. This guard no longer lounged lethargically; he pointed at Conan with astonishment and shouted unintelligible questions.
Conan reached the foot of the ladder. The guard was armed, and it would not be easy to climb to the platform in the face of his weapons. But then a dragon, who had failed to get a piece in the scramble for the corpse, turned back toward Conan, its long, forked tongue flicking out. Conan decided to chance the guard rather than again face the horde of giant lizards.
With the speed of a monkey scrambling out of the way of a lion, Conan went up the ladder. By the time the first of the reptiles had reached its foot, he was twenty feet up3 well out of their reach.
Next, he had to cope with the guard. He drew the dirk from the sheath at his back and put the blade between his teeth. Then he resumed his climb.
Soon he found himself staring up into the astonished brown face of the guard, who squatted at the edge of his platform. The man jabbered at Conan and threateningly waved his glass-bladed sword.
Holding a rung just out of the guard's reach with his left hand, Conan hooked a knee around a rung to give himself purchase. Then he took the dirk from between his teeth. Closing one eye to sight on the guard's form, he brought his right arm slowly back - then sharply forward. The dirk flashed through the air, struck the guard in the hollow at the base of his throat, and buried itself halfway to the hilt.
With a choking gurgle, the guard staggered to his feet. He dropped his sword with a clatter to clutch at the blade buried in his throat. Then he teetered forward and plunged off the platform. Conan had to fend off his falling body to keep from being knocked off the ladder himself. The guard struck the floor of the chamber with a thud. A strangled shriek was cut off by the crunch of a pair of dragon's jaws. From below., sounds of another reptilian feast wafted up.
Breathing hard, Conan hauled himself up to the platform and sat down on the edge with his booted feet dangling. The last hour had seen him through some of the closest calls of an adventurous life.
Some dragons remained at the foot of the ladder, gazing hopefully up at him. Little by little they trailed away. Those that had failed to fill their bellies from the recent windfalls resumed their circle around the bright spot in the center of the floor. Presently, with a whistle and a thump., another mutilated corpse fell down the shaft, to be pounced upon and squabbled over by the scaly reception committee.
Having recovered from his exertions, Conan got up and explored. Behind the platform was a tunnel closed by a bronze grille. Beyond the grille, steps led up into the gloom. The grille opened at Conan's touch. Inside this gate was a large recess in the wall, and in this recess a gigantic bronze wheel was mounted. The spokes projected beyond the rim to form handles, so that it resembled, on a larger scale, one of the tiller wheels that Conan had seen on large Zingaran galleons. The wheel was thick with the green, waxy coating of verdigris. It must have stood there for ages since last being turned.
Conan frowned in thought. His gaze wandered to the huge bronze doors across the chamber, beyond the circle of ghoulishly waiting dragons. Why should those doors have been put there in the first place? They must have cost the folk of Ptahuacan a tremendous lot of labor to install. Presumably, a passage led from the other side of them to the world above. But all they were good for was to loose the horde of dragons upon the citizens. Why should the hierarch wish any such thing?
