The Zero Stone

by Andre Norton

  But that was full of clouds, and while it was still warm enough to make one pant when exercising, there was no sun. Insects buzzed about, so that at times I had to swing my hand before my face to clear my vision. But none bit my flesh. Perhaps I was so alien to their usual source of nourishment that they could not.

  There was no sign of any pursuit, and Eet, though he had ceased to communicate when we began this dash, would, I believed, raise the warning if it were needed. I appeared to possess some importance to him, though his evasiveness concerning that bothered me.

  Again pools began to link together, forcing me to make more and more detours from the direct path the stone indicated. I had no wish to splash through even the shallows of those evil-looking, bescummed floods. Who knew what might hide below their foul surfaces? Perhaps the insects did not find me tasty, but that did not mean other native life would be so fastidious.

  I had no idea of the length of the planetary day, but it seemed to me now that the cloud blanket overhead did not account for all the lack of light and that this might be late afternoon. Before night we must find some safe place in which to hole up. If the natives were nocturnal, the advantage of any encounter would rest with them.

  The water pushed me back, farther and farther to the right, while the tug of the stone was now left, straight into the watery region. Its pull became so acute and constant that I finally had to slip the loop from my hand and put it back in the pouch, lest it overbalance me into one of the very sinks I fought to skirt.

  There was much evidence that not only had this lake been far larger in the not too far-distant past but it was still draining away in the very direction the ring pointed. It was hard going and from time to time I demanded of Eet reassurance that we were not being followed. But each time he reported all clear.

  It was decidedly darker and I had yet found no possible place to lie up for the night. Too many tracks in the mud suggested that life, large life, crawled from pond to lake, came from the water and returned to it. And the size of some of those tracks was enough to make a man think twice, three, a dozen times, before settling down near their roadways.

  I had passed the first of the outcrops before I really noticed them, so covered were they with dried mud which afforded anchorage to growing things. It was when I scrambled up on one to try for a better look at what might lie ahead that it dawned on me that they were not scattered without pattern but were set in a line which could not be that of nature alone.

  My foot slipped on the surface and I slid forward, trying to stop my fall by digging the point of the knife well in. But the stone resisted my blade, which came away with an almost metallic sound, scraping off a huge patch of mud.

  What I had uncovered was not rough stone, but a smooth surface which had been artificially finished. When I touched it I could not be sure it was stone at all. It had a sleekness, almost as if the rock had been fused into a glassy overcoat - though in places this was scaled and pitted.

  In color it was dull green, veined with ocher strata. Yet it was not part of a wall, for the stones did not abut, but had several paces distance between them. Perhaps there had once been some link of another material now vanished.

  The outcrops ran in the direction the stone urged upon me, marching down to the lake, partially submerged near the shore, water lapping their crowns farther out, then entirely covered.

  As I continued along the lake, now alert to any other evidence, I came across a second line of blocks, paralleling those swallowed by the water. These I took for a guide. They were certainly the remains of some large erection, ancient though they appeared. And as such they could well lead to a building, or even a ruin which would shelter us.

  “Just so,” Eet agreed. “But it would be well to hurry faster. Night will come soon under these clouds and I think a storm also. If more water feeds this lake-“

  There was no need for him to underline his thought. I jumped from one of those blocks half buried in the muck to the next, listening for warning thunder (if storms on this planet were accompanied by such warnings) and fearing to feel the first drops of rain. The wind was growing stronger and it brought with it a low wailing which stopped me short until Eet’s reassurance came:

  “That is not the voice of a living thing- only sound-“ He sniffed as thoroughly as the trunk-nosed native.

  The blocks for the first time now were joined together, rising into a wall, and I dropped down to walk beside it. It soon topped my head. There were too many shadows in its overhang, so I edged into the open.

  I would have climbed again after a while for a better look at the country ahead, but the tops of these blocks were not level. Instead they were crowned with projections, the original form of which could not be guessed, for they were eroded and worn to stubs which pricked from them at meaningless angles.

  On this side of the wall the signs of flood ceased, except in some places where apparently waves had spilled over the top, in a few instances actually turning and twisting the mighty blocks of the coping over which they had beaten.

  There were no trees here. We moved across an open space which gave footing only to brush that did not grow high. Where one of the waves had topped the wall, I saw that I walked on a coating of soil overlying pavement, some of which had the same fused look as the surface of the wall.

  If I walked some road or courtyard, there was no other wall. The clouds were very thick and dark now, and the first pattering rain began. The wall was no protection, nor was there any other shelter in this sparsely grown land. I ran on, my tiring body having to be forced to that pace, both my pack and Eet weighing cruelly on me.

  Then the wall beside which I jogged made a sharp turn left and ended in a three-sided enclosure. It had no roof, but those three sides were the best protection I had seen. We could stretch the shelter from the wreck over us to afford some cover. Also, I was not going to blunder on in the dark. So I darted into that enclosure, squatting down in the corner I judged easiest to defend. There we huddled, the covering draped over my head and shoulders, Eet in my lap, as the night and the storm closed down upon us.

  But we were not quite in the dark. As I changed position I saw the faintest of glows from the pouch which held the stone, and when I pried open the top a fraction, there was a thin ray of light. Just as it had come alive before, so it was registering energy now. Was this ruin its goal? If so, had the LB led us directly to the home planet from which the derelict had lifted eons ago? Such a supposition could not be ruled out as fantastic. The LB could have been set on a homing device and the drifting ship might have met its fate soon after take-off. Unwittingly we might have made a full circle, returning the ring to the world on which it was fashioned. But the age of the stones at my back certainly argued that those who had dwelt here were long gone, that I had stumbled on traces of one of the Forerunner races, about whom we know so little and even the Zacathans can only speculate.

  To spend a stormy night amid alien ruins of incalculable age was not my idea of a well-chosen pastime. My search for gems had taken me into many strange places, but then I had only been second to Vondar, leaning on his knowledge and experience. And earlier I had looked to my father, not only for physical protection, but for that teaching which would aid in survival.

  As I crouched there with the rain drumming on the thin sheet which was my only roof, I was only partially aware of the night, the alien walls, the need for alertness. One part of my mind sought back down the years, to my father’s first showing of the ring with the zero stone- for that was what he had once termed it, a challenge to his knowledge and curiosity.

  It had been found on a suited body floating in space. Had that body been one of the crew of the derelict? And my father had died at the hands of someone who had then searched his office, the zero stone the prize the murderer sought.

  Then Vondar Ustle and I had been entrapped at the inn on Tanth. And I could accept that that had not happened by a chance pointing of the selective arrow. It had been planned. Perhaps they h
ad believed that, being off-worlders, we would resist the priests just as we had, and both be slain, as Vondar was. They could not have foreseen that I would break away and reach the sanctuary.

  For the first time I resented my bargain with Ostrend. And the trader in me regretted the gems I had paid for a passage which had already been arranged by another. So- I was to have been transported to Wayside and turned over there to those paying for my rescue. For what purpose? Because I was my father’s son, or his reputed son, and so might have possession of, or knowledge of, that very thing which now glowed faintly against my chest?

  Again by chance I had escaped- the fever- a contagion picked up on Tanth, or on that unnamed world where the people had so mysteriously disappeared? That sickness which had so oddly struck just at the proper time- Oddly struck!

  “Just so,” Eet answered with his favorite words of agreement. “Just so. You alone of the crew sickening so- why did it take you so long to wonder about that?”

  “But why? I know Valcyr picked my cabin to give birth- that must have been chance-“

  “Was it?”

  “But you could not have-“ What if he could? As helpless as Eet’s body had looked when I found Valcyr with him on the bunk, did that necessarily mean that his mind-?

  “You are beginning to think,” Eet replied approvingly. “There was a natural affinity operating between us even then. The crew of the ship were a close-knit clan. It was necessary for me to find one detached from that organization, one who could furnish me with what I needed most at that time, protection and transportation away from danger while I was in a weak state. Had I encountered them at a later period I would not have been so endangered. But I needed a partner-“

  “So you made me ill!”

  “A slight alteration of certain body fluids. No danger, though it appeared so.” There was a complacency in his answer which for a moment made me want to hurl Eet out into the dark and whatever danger might lurk there.

  “But you will not,” he answered my not completely formulated thought. “It was not only a matter of expediency which made me choose to reveal myself to you. I spoke of natural affinities. There is a tie between us based on far more than temporary needs. As I have said, this body I now wear is not, perhaps, what I might have chosen for this particular phase of my existence. I have modified it as much as I can for now. Perhaps there will be other possible alterations in the future, given time and means. But I do have senses which aid you. Just as your bulk and strength do me. I believe you have already discovered some of the advantages of such a partnership.

  “We are still far from any situation you may term safe. And our alliance is very necessary to both of us. Afterward we can choose whether to extend it.”

  That made sense - though I disliked admitting that this small furred body I could crush in my two hands contained a personality forceful enough to bring me easily to terms. I had had few close contacts with anyone in the past. My relationship with Hywel Jern had been that of pupil to teacher, junior officer to commander. And while Vondar Ustle was a man of easier temperament, far more outgoing than my father, the relationship had remained practically the same for me when I entered his service. Beyond that I had had no deep ties with any man or creature. But now I had been summarily adopted by Eet, and it appeared that my will did not enter into the agreement any more than it had with Hywel or Vondar - for it had been of their desire in both cases. But - my anger arose- I was not going to stand in the same relationship to Eet!

  “They come!” Eet’s warning shocked me out of my thoughts.

  We had been so long without any contact with the natives that I had believed they had given up. If they moved in now, we might find our shelter a trap.

  “How many and where?” Eet was right; in such a situation I must depend upon his senses.

  “Three-“ Eet took his time to answer. “And they are very hesitant. I think that this place represents danger to them. On the other hand - they are hungry.”

  For a second or so, that had no meaning for me. Then I stiffened. “You mean-?”

  “We - or rather you - represent meat. Contact with such primitive minds is difficult. But I read hunger, kept in check mainly by fear. They have memory of danger here.”

  “But - by the signs we have seen, there is plenty of game here.” I remembered the fresh tracks, the evidences of life we had seen in profusion, and how easy it had been for the fisherman to scoop out his prey.

  “Just so. A puzzle as to why our trail would draw them past easier hunting.” Eet did seem puzzled. “The reason, I cannot probe. Their minds are too alien, too primitive to read with any clarity. But they are aroused now past the limit of prudence. And they are most dangerous in the dark.”

  I fingered the beamer on my harness. If the creatures were mainly night hunters, a flash in their eyes would dazzle them for a moment. But my own folly in picking this hole with its towering walls about us might be the deciding factor - against us.

  “It is not as bad as all that,” Eet broke in. “There is a top to the wall-“

  “Well above my reaching. But if you can climb it - climb!” I ordered.

  I felt a sharp tug at one corner of the covering I had drawn over us.

  “Let this free,” Eet countered. “Climb I can, but perhaps we shall both be safe because of the fact that my claws are useful.” He was out of my lap, dragging the cover behind him, though it was a burden which pulled his head to one side.

  “Hold me up,” he commanded then, “as high as you can reach, and take some of the weight of this thing!”

  I obeyed, because I had no counterplan, and I had come, during our association, to give credit to Eet. I lifted his body, held it above my own head, and felt him catch hold, and draw himself up. Then I fed along the length of the shelter cloth, keeping its weight from pulling him back as he went. Suddenly it was still, no longer tugged.

  “Tie the knife to it and let go-“ Eet ordered.

  Let my only weapon out of my hands? He was crazy! Yet even as my thoughts protested, another part of me set my hands busy knotting that tool-weapon to the end of the dangling cloth. I heard it, even through the storm, clang and rap against the stone as it was drawn aloft by Eet.

  I faced around, to the open side of the enclosure. Though I did not have Eet’s warning alert, I was sure that the aliens no longer hesitated, that they moved through the darkness. I pressed the button on the beamer, looking down the ray path.

  They did indeed gather there, half crouched, their clubs ready in their fists. But as the light struck them full on, they blinked, blinded, their small mouths opening on thin, piping cries. The middle one dropped to his knees, his arm flung up to shield his hideous face from the light.

  “Behind you- up!” Eet’s mental cry was as loud as a shout might have been in my ear. I felt the brush of something at my shoulder, flung out my hand to ward it off, and touched the fabric of the shelter. My fingers closed about it and I tugged. But it did not fall; somewhere aloft it was anchored, to give me a possible ladder to safety.

  Dared I turn my back upon the three the light still held prisoners? Yet how long could I continue to hold them so? I must chance it-

  If only that improvised rope and whatever Eet had found aloft to anchor it would hold under my weight! But that was another chance I must take. I gave a short leap and caught the dangling folds with both hands, swung out a little to plant my feet against the wall, and climbed, or rather walked up that surface, the shelter my support.

  TEN

  I was not to escape so easily. There arose behind me a shrilling that topped the sound of the storm. Something thudded against the wall only inches from me, rebounding to the ground. I had kept the beamer switched on and the light jerked back and forth as I struggled to put distance between myself and the natives below. Perhaps that moving light misled them, or perhaps they were less adept with their clubs than we credited them with being. However, one hurled weapon grazed my leg and almost broke my hold on the fabri
c rope.

  Fear alone gave me the strength to pull up on the rough crest of the wall. My leg was numb and I was afraid to trust my weight to it, so I dragged along like a broken-legged creature. The claws of the natives stuck in my mind. Those should aid them in gaining our perch.

  Up here the wind and the rain buffeted us. I had not realized how much protection the walls had afforded below. I clung to the knobs and broken projections and pulled myself along, though I took time to switch off the beamer that I might not so brightly advertise our going.

  “On, to your right now, and ahead-“ Eet ordered.

  I followed the line of the fabric to its end, found where the knife pinned it firmly into a crack between an eroded knob and the wall, paused long enough to worry it loose, and thrust that weapon into my harness.

  To the right and ahead? The blasting of the storm was such that for some long moments I was not sure of the difference between right and left, having to think of my hands as guides. Eet’s direction would apparently take me over the wall. Yet I was certain he did not mean us to descend again.

  I discovered as I crawled on, dragging my aching leg, that here the wall was joined by another, leading off at a sharp angle in the direction Eet had indicated. It was slow and rough going, for the crest was as encumbered with humps, hollows, and stubs as the other had been. But at least they now served as anchorages against the wind and drive of rain.

  The visibility was nil as far as I was concerned. I had to depend upon my sense of touch and Eet’s guidance. Every moment I feared to hear the shrilling which would announce that the club holders were hard behind us.

  The numbness in my leg was wearing off, leaving behind an ache which, when I barked that limb against one of the projections, made me yowl with pain. But I did not try to get to my feet. Crawling this uneven way seemed the safest.

  We were heading out from the place where we had sheltered, directly into a dark unknown. Now I could hear, above the storm, not the shrilling of pursuers, but a roaring. And it was toward that that we headed.
