This cave - was not completely natural. The Master had suggested that this might be the case. The entire mountain, he had said, was unnatural-though he did not know how it had come about.
The chances of an unnatural cave connecting to a natural mountain seemed good.
Var, eye, ear and nose now adjusted to this environment, moved on. His mission was to chart a route into the dread mountain-a route that bypassed the surface defenses, and that men could follow. If he found the route, and kept it secret from the underworiders, the empire could have an almost bloodless victory.
If there were no route, there would be a much worse battle on the surface. Lives depended on his mission perhaps the life of the Master himself.
The tunnel branched. The pipe going toward the mountain was clogged with rubble; the other was wide and clear. Var knew, why: when rainfall was heavy, water coursed this way, removing all obstructions. He would have to follow the water, to be sure of getting anywhere but he would also have to pay close attention to the weather, lest the water follow him. Was it possible to anticipate a storm underground?
The passage widened as it descended. Its walls were almost vertical and metallic; overhead, metal beams now showed regularly. It debouched into an extremely large concorse with a long pit down the center. He peered down, noting how the delta of rubble tipped into that chasm. He did not venture into it himself. The bottom was packed with slick-looking mud, and there were dark motions within that mud: worms, maggots or worse. There had been a time when he had eaten such with gusto, but civilization had affected his appetite.
He tapped the level surface of the upper platform. Under the crusted grime there was tile very like that of a hostel.
The footing was sound.
The Master had told him that there were many artifacts in this region reninining from the time before the Blast. The Ancients had made buildings and tunnels and miraculious machines, and some of these remained, though no one knew their function. Certainly Var could not fathom the use of such a large, long compartment with a tiled floor and a pit dividing it completely.
He followed it down, listening to distant rustles and sniffing the stale drifts of air. Though his eyes were fully adapted to the gloom, he could not see clearly for any distance. There was not enough light for any proper human vision, this deep in the bowel.
Soon the platform narrowed, and finally the wall slanted into the pit, and there was nowhere to go but down. The Ancients could not have used this for walking then, since it went nowhere. They had been, the Master said, like the crazies and like the underworlders, only more so; there was no fathoming their motives. This passage proved it. To put such astonishing labors into so useless a structure....
He climbed down carefully. The drop was only a few feet, not hazardous in itself. It was the life in that lower muck that he was wary of. Familiar, it might be harmless, as familiar poison-berries were harmless-no one would eat them. Unfamiliar, it was potentially deadly.
But the mud was harder than he had supposed; the gloom had changed its seeming properties. Rising from it were two narrow metal rails, side by side but several feet apart. They were quite firm, refusing to bend or move no matter what pressure be applied, and they extended as far as he could discern along the pit. He found that by balancing on one, he could walk along without touching the mud at all, and that was worthwhile.
He moved. His hoof-toes, softened some by the shoes he had had to wear among men but still sturdy, pounded rapidly on the metal as he got the feel of it, and his balance became sure despite the darkness and the slender support. The pit-tunnel was interminable, and did not go toward the mountain. He hesitated to go too far, lest a rainstorm develop above and send its savage waters down to drown him before he could escape. Then he realized that this tunnel was too large to fill readily, and saw the dusky watermarks on its cold walls: only two or three feet above the level of the rails. He could wade or swim, if it came to that.
Even so, it was pointless to follow this passage indefinitely. It was now curving farther away from the mountain, so could hardly serve the Master's purpose.
He would follow it another five minutes or so, then turn back.
But in one minute he was stopped. The tunnel ended.
Rather, something was blocking it. A tremendous metal plug, with spurs and gaps and rungs.
Var tapped it with his stick. The thing was hollow, but firm. It seemed to rest on the rails, humping up somewhat between them so as not to touch the floor.
Could there be a branching or turning~ beyond this obstacle? Var grabbed hold and hauled himself up the face of the plug, curling his fingers stiffly around what offered. He was searching to learn whether there were a way through it.
There was. He poked his head into the musty interior, inhaling the stale air. He knocked on the side of the square aperture and it clanged. He could tell the surrounding configuration of metal by the sound and echo. He climbed inside. -
The floor here was higher than outside. It was mired in a thick layer of dirt and droppings. This was like a badlands building, with places that could be seats, and other places that could be windows, except that there was only a brief space between the apertures and the blank tunnel wall. And all of it was dark. Eyes useless, ears becoming confused by the confinement of sound, Var finally had to use the crazy flashlight the Master had given him. For there was life here.
Something stirred. Var suppressed a reflexive jump and put the beam of light on it, shielding his eyes somewhat from the intolerable glare. Then he got smart and clapped his hand over the plastic lens, holding in the light so that only red welts glowed through. He aimed, let digits relax, let the beam shove out to spear its prey.
It was a rat-a blotched, small-eyed creature that shied away from the brilliance with a squeal of pain.
This Var knew rats did not travel alone. Where one could live, a hundred could live. And where rats resided, so did predators. Probably small ones-weasels, mink, mongoose-but possibly numerous. And the rats themselves could be vicious, and sometimes rabid, as he knew from badlands buildings.
He walked quickly down the long, narrow room, seeing a doorway at its end outlined by the finger illuminated beam. He had to move along before too many creatures gathered. Rats did not stay frightened long without reason.
Beyond the door was a kind of chamber and another door. More mysterious construction by the Ancients!
Corning down the hail beyond that was a snake. A large one, several feet long. Not poisonous, he judged-but unfamiliar and possibly mutant. He retreated.
The rats were already massed in the other room. Var strode through them, shining his light where he intended to step, and they skittered back. But they closed in behind, little teeth showing threateningly. Too aggressive for his comfort. He had stirred up an ugly nest, and they were bold in their own territory.
He scrambled out the window and dropped to the dank floor of the tunnel His feet sank in the mud; it was softer here, or he had broken through a crust. He turned off the flash, waited a moment to recover sight, and found a rail to follow back down the tunnel.
Some other way would have to be found. It was not that the rats and snakes stopped him-but there were sure to be other animals, and a troop of men would stir them all up. In any event, the direction was wrong.
But he could not escape the angry stir so easily. Something silent came down the tunnel. He felt the moving air and ducked nervously. It was a bat-the first of many.
What did all these creatures feed on? There seemed to be no green plants, only mold and fungus.
And insects. Now he heard them stirring, rising into the foul air from their myriad burrows.
Apprehensively, he flashed his light.
Some were white moths.
Var's heart thudded. There was no way he could be sure of avoiding these deadly stingers here except by standing still-and that had its own dangers. He had to move, and if he brushed into one-well, he would have a couple of hours to reach the surfac
e and seek help before the poison brought him to a full and possibly fatal coma. Certainly fatal if be succumbed to it here in the tunnels, where men Would never find him. Even if he received only a minor sting, that weakened him, and then it rained...or if the rats and snakes became more bold, and ventured along the rail....
But not all white moths were badlands mutants. These seemed smaller. Maybe they were innocuous.
If these were of the deadly variety, this route was doomed. Men could not use it, however directly it might lead to the mountain. That would make further exploration useless.
Best to know immediately. Var ran along the track until he saw the high platforms. He climbed up and oriented himself, identifying his original point of entry. Then he ran after a white moth and swooped with his two hands, trapping it. It was his fingers that were awkward, not his wrists or hands.
He held the insect cupped clumsily between his palms, terrified yet determined. For thirty seconds he stood there, controlling his quivering, sweating digits.
The moth fluttered in its prison, but Var felt no sting.
He squeezed it gently and it struggled softly.
At last he opened his hands and let the creature go. It was harmless.
Then he rested for five minutes, regaining his equilibrium. He would much rather have stepped into the circle with lame hands against a master sworder, than against a badlands moth like this. But he had made the trial and won. The way was still clear.
He crossed the double-rail pit and mounted to the far platform. There were tunnels leading away in the proper direction. He chided himself for not observing them before. He selected one and ran down it.
And halted. His skin was burning.
There was radiation here. Intense.
He backed off and tried another branch. Even sooner he encountered it. Impassable.
He tried a third. This went farther, but eventually ran into the same wall of radiation. It was as though the mountain were ringed by roentgen....
That left the railed tunnel, going in the other direction. This might circle around the flesh-rotting rays. He had to know.
Var dropped down and ran along the track. He went faster than before, because time had been consumed in the prior explorations, and he had greater confidence -in the narrow footing. Probably a man with normal, soft, wide feet could not have stayed on the track so readily. Or have felt its continuing solidity by the tap of nail on metal-an important reassurance, in this gloom.
On and on it went, for miles. He passed another series of platforms, and felt the barest tinge of radiation; just before he stopped on the track, it faded, and he went on. Such a level of the invisible death was not good to stay in, but was harmless for a rapid passage.
The rubble between the tracks became greater, the walls more ragged, as though some tremendous pressure had pressed and shaken this region. He bad seen such collapsed structures during his wild-boy years; now he wondered whether the rubble and the radiation could be connected in any way. But this was idle speculation.
He was very near the mountain now. He came to a third widening of the tunnel and platform-but this one was in very bad condition. Tumbled stone was everywhere, and some radiation. He ran on by, nervous about the durability of this section. A badlands building in such disrepair was prone to collapse on small provocation, and here the falling rock would be devastating.
But the track stopped. It twisted about, unsettling him unexpectedly (he should have paid attention to its changing beat under his tonails), and terminated in a ragged spire, and beyond that the rubble filled in the tunnel until there was no room to pass.
Var went back to the third set of platforms. He crawled up on the mountain-side, avoiding rubble and alert to any sensation in his skin. When he felt the radiation, even so slight as to be harmless, he shied away. The Master had stressed that a route entirely clear must be found, for ordinary men might be more sensitive to the rays than Var, despite their inability to detect it without click-boxes.
Two passages were invisibly sealed off. The third was clear, barely. There were large droppings in it, showing that the animals had already discovered its availability. This in turn suggested that it went somewhere-perhaps to the surface-for the animals would not travel so frequently in and out of a dead end.
It branched-the Ancients must have had trouble making up their minds!-and again he took the fork leading toward the mountain. And again he ran into trouble.
For this was the lair of an animal-a large one. The droppings here were ponderous and fresh-the fruit of a carnivore. Now he smelled its rank body effusions, and now he heard its tread.
But the tunnel was high and clear and he could run swiftly along it. It was narrow enough so that any creature could come at him only from front or back. So he waited for it impelled by curiosity, if it were something that could be killed to clear the passage for human infiltration of the mountain, he would make the report. He cupped the light and aimed it ahead.
Rats scuttled around a bend, squinted in the glare, and milled in confusion. Then a gross head appeared: frog-like, large-eyed, horny-beaked. The mouth opened toothlessly. There was a flash of pink. A rat squealed and bounced up-then was drawn by a pink strand into that orifice. It was an extensive, sticky tongue that did the hauling.
The beam played over one bulging eye, and the creature blinked and twisted aside. It seemed to be a monstrous salamander. As Var stepped back, some fifteen feet of its body came into sight. The skin was flexible, glistening; the legs were squat, the tail was stout.
Var wasn't certain he could kill it with his sticks, but he was sure he could hurt it and drive it back. This was an amphibian mutant. The moist skin and flipper-like extremities suggested that it spent much time in water. And his skin reacted to its presence: the creature was slightly radio-active.
That meant that there was water-probably a flooded tunnel. Water that extended into radiation, and was contaminated by it. And there would be other such mutants, for no creature existed alone. This was not a suitable route for man.
Var turned and ran, not fearing the creature but not caring to stay near it either. It was a rat eater, and probably beneficial to man in that sense. He had no reason to fight it.
That left the other fork of the passage. He turned into it and trotted along, feeling the press of time more acutely. He was hungry, too. He wished he could unroll his tongue and spear something tasty, many feet away, and suck it in. Man didn't have all the advantages.
There was another cave-in, but he was able to scramble through. And on the far side there was light.
Not daylight. The yellow glow of an electric bulb. He had reached the mountain.
The passage was clean here, and wide. Solid boxes were stacked in piles, providing cover. This had to be a storeroom.
Near the opening through which he had entered there was food: several chunks of bread, a dish of water.
Poison! his mind screamed. He had avoided such traps many times in the wild state. Anything set out so invitingly and inexplicably was suspect. This would be how the underworlders kept the rats down.
He had accomplished his mission. He could return and lead the troops here, with their guns. This chamber surely opened into the main areas of the mountain, and there was room here for the men to mass before attacking.
Still he had better make quite sure, for it would be very bad if by some fluke the route were closed beyond this point. He moved deeper into the room, hiding behind the boxes though there was no one to see him. At the far end he discovered a closed door. He approached it cautiously. He touched the strange knob- and heard footsteps.
Var started for the tunnel, but realized almost immediately that he could not get through the small aperture unobserved in the time he had. He ducked behind the boxes again as the knob rotated and the door opened. He could wait, and if discovered he could kill the man and be on his way. He hefted his two sticks, afraid to peek around lest he expose himself.
The steps came toward him, oddl
y light and quick. To check the poison, he realized suddenly. The food would have to be replaced every few hours, or the rats would foul it and ignore it. As the person passed him, Var poked his head over between shielding flaps and looked.
It was a woman.
His grip tightened on the sticks. How could he kill a woman? Only men fought in the circle. Women were not barred from it, specifically; they merely lacked the intelligence and skill required for such activity, and of course their basic function was to support and entertain the men. And if he did kill her what would he do with the body? A corpse was hard to conceal for long, beøause it began to smell. It would betray his presence, if not immediately certainly within hours. Far too soon for the nomadS to enter secretly.
She was middle-aged, though of smaller build than the similarly advanced woman he had known, Sols. Her hair was short, brown and curly, but her face retained an elfin quality and she moved with grace. She wore a smock that concealed her figure; had her face and poise not given her away, Var might have mistaken her for a child because of her diminutive stature. Was this what all underworiders were like? Small and old and smocked? No need to worry about the conquest, then.
She glanced at the bread, then beyond-and stopped.
There, in the scant dust, was Vat's footprint. The round, callused ball, the substantial, protective, curled-under toenails. She might not recognize it as human, but she had to realize that something much larger than a rat had passed.
Var charged her, both sticks lifted. He had no choice now.
She whirled to face him, raising her small hands. Somehow his sticks missed her head and he was wrenched about, half-lifted, stumbling into the wall, twisting, falling.
He caught his footing again and oriented on her. He saw her fling off her smock and stand waiting for him, hands poised, body balanced, expression alert. She wore a brief skirt and briefer halter and was astonishingly feminine in contour for her age. Again-like Sola.
He had seen that wary, competent attitude before. When the Master had captured him in the badlands. When men faced each other in the circle. It was incredible that a woman, one past her prime and hardly larger than a child, should show such readiness. But he had learned to deal with oddities, and to read the portents rapidly and accurately.
