The light was convenient, but Conan realized that by now he must be far off the track he had originally set himself. While fleeing from the rats, he had taken whatever path seemed to offer the fewest obstacles, heedless of the route he had so carefully memorized with the help of Metemphoc the master thief. There seemed to be no hope of retracing his steps and again picking up the thread of his original route. Even if he could somehow get back up the underground river, he might find the horde of giant rats still lingering where he had left them. And now he did not even have a sword to fight them off with.
He explored the vast cavern further. Titanic stalagmites rose here and there from the rocky floor to approach and sometimes to join with stalactites descending from above. These natural pillars reminded Conan of the columns of primitive temples to the gods of the underworld. Their immensity dwarfed even his giant form.
Now that his hunger was somewhat appeased, he gave thought to procuring a more effective weapon than the dirk. Although this was a stout and formidable dagger, he felt he needed something with more reach, for there was no telling what other nameless denizens of the underworld he might meet in his subterranean wanderings.
Stalagmites, he observed, were all rounded and blunt at the upper end. Wanting something he could use as a spear, he chose a slender stalactite instead. He picked up a loose lump of limestone, weighing perhaps twenty pounds, and swung it against the tapering shaft. The stalactite broke off; Conan dropped the piece of limestone and caught the falling stalactite. At the boom of the falling lump, half the glowworms went out and then slowly returned to their normal brightness.
He hefted his new weapon. It was a four-foot shaft of stone, as thick as his wrist at one end and tapering to a point at the other. While the point was not so sharp as that of a real spear, it would still pierce the body of a foe when backed by Conan's still-powerful muscles. It could also be grasped by the small end and swung as a club, although Conan entertained doubts of the strength of the material. It could even be thrown as a javelin for a short distance.
Thus armed, Conan felt fit to challenge even the nameless terrors of this dark realm. Cautiously, he began exploring again, in the direction in which the cave seemed to extend the farthest.
As he walked, the cavern narrowed and the ceiling became lower. The glowworms became fewer, so that in the increasing gloom Conan was forced to move warily, probing ahead of him with the stalactite lest he fall into some hole. His position was hazardous enough as it was, without the additional discomfiture of suddenly finding himself plunging down some well or shaft hundreds of feet deep.
As it was, he stumbled over an irregularity in the cavern floor and bumped into a stalagmite about his own height. The slender stone column broke off and toppled over with a loud boom, which reverberated in the confined space. Instantly every nearby glowworm winked out, leaving Conan in virtually complete darkness.
'Ahriman eat these accursed caves!' he growled. He continued in the direction in which he had been headed, feeling ahead with his feet and with the point of the stalactite.
Then his outstretched club touched something that moved. Conan froze motionless., straining his eyes and ears for some clue to the nature of the invisible being in his path.
A loud hiss came from the darkness before him, tike the hiss of a serpent but magnified many times over. A rank, reptilian odor filled his nostrils. He would have noticed it sooner but for the faint breeze that blew against his back and hence wafted the stench away from him until he was almost upon its source.
Sweat started on Conan's brow. Had he stumbled into a nest of snakes? Like most northern barbarians, he detested the snakes that swarmed the jungles of hot southern lands. Several times in his career he had experienced close calls with serpents far larger than any of the common species - monsters over fifty feet long, with heads as big as those of horses.
Thinking silently to withdraw, he took a step backwards. Then came a scraping sound, as if some heavy weight were being dragged across the stone before him. Conan halted and held his breath lest the slightest sound betray his presence.
Then the glowworms began to light up again. As their faint, greenish radiance suffused the tunnel, a well of cold, green light appeared in front of Conan, on a level with his own eyes. It was a huge eye. Then it swung to one side, and Conan saw that it was one of a pair.
