The Gray Ones threw back their heads and broke into a wild, tormented howling, like unto the cries of those d.a.m.ned and doomed. They dashed back and forth, finally away from the river, retreating into the broken country behind.

After them the Keplians neighed, reared. Some threw their riders before they followed the wolfmen. Some of the men managed to keep their seats, but those who fell lay p.r.o.ne, unmoving, on the ground as if struck dead. Only the two hooded ones slid from their unhappy mounts, which plunged off, and stood together, watching Kaththea. But they made no move to turn their weapon tubes upon us.

My sister's arms dropped to her side. She spoke by open mind thought so I understood her.

"Say this to your overlord: The hawk does not hunt when the eagle flies. Nor does one who wears the cloak of power send to an equal less than a Herald of Banners. If he would have words with me, let him say them as we have always dealt-face to face." She laughed. "Remind him of what you see now; it will hearten him, for there can be a bargaining."

They gave no outward sign that they understood, any more than they replied; they simply turned and walked away, presenting their backs to us as if they had no fear of any attack. Now Kaththea again fastened the scarf back in shrouding folds.

"You sent a challenge to Dinzil," I said aloud.

"I sent a challenge," she agreed. "He will not again, I believe, dispatch underlings to hunt us as if some slaves of his were escaping. When he comes, it will be full in the power he thinks he has."

"But-"

"But that is what you fear, brother? You need not. Dinzil thought to make of me a tool, as one uses pincers of iron to take a blazing coal from the heart of a fire. For a while"-she tucked the loose ends of her scarf into the front of her jacket to keep them tight-"he might have had a small part of it. Only-you see-he exposed me to much he had learned. Since I had already been well taught in another school, I could fit that learning into a new pattern which he does not know. Let him believe I have power and he will be twice eager to treat with us. Shall we go?" She turned her m.u.f.fled head from one side to the other, and then pointed to our left. "I dislike water walking. I do not believe we shall again be challenged by anything in this land. The Valley lies that way."

"How can you be sure?" Her arrogance was growing. She snapped her thoughts now as a hunter snaps a riding whip against a boot. Surely the Kaththea I had known all my life was further and further from me.

"The Valley is a reservoir of power, surely you cannot deny that. As such it puts forth a signal for all those who can feel. Try it yourself, brother, with that mysterious fire sword of yours."

So much was I under her command at that moment, that I did raise the sword, holding it only loosely to see if it could act as a pointer. I swear that I did not incline it, but it did point in the same direction she had indicated.

Against my will we left the river, though I knew that sooner or later we would have had to do so, since I would not have gone underground again.

We were quickly through that wholesome growth along the stream bed and into the blasted land which laced this rolling country. Kaththea marched straight ahead, as one who has no need to fear, but I held the sword as a guard against what might lie here, avoiding, making her avoid, certain bushes, stones, and the like, when the runes warned. We had not gone far before I knew that we had skulkers to our right and left, also trailing behind. Some of the shapes I sighted were ones I had seen before in the ranks of evil, others new to me. Not all were foul or monstrous seeming. If they were illusions they were proof against my desire for clear sight.

None of these moved to obstruct us in any way, save that they were ready to close in upon the command of their warlord. I kept ever alert, waiting for Dinzil to appear and accept Kaththea's challenge.

For such a battle I was ill-equipped. I had but one ultimate weapon, as Orsya had pointed out. There were those words from Lormt which had been answered. I might call again on what had so answered. Though to do so was a risk only to be taken by one in the depths of despair at a time of complete loss of hope.

Good spots appeared here and there in this seared land, mostly, I noted, about springs, pools, or small runlets, as if water was a factor in holding back the evil which had blasted so much of the country. It was a hard way to follow, for, as I had seen from my rock perch in the Heights, it was very broken, sharp ridges dividing narrow ravines, so that it seemed to me we were eternally climbing, or descending to climb again. Yet Kaththea appeared to be in no way baffled at direction and unhesitatingly took the lead, always bearing to the left. Now I could see the Heights themselves as proof she was right.

We stopped at last beside one of the pools of sweet water.

I ate one of the few remaining roots Orsya had given me, though I could have finished them all. But again Kaththea would have no food, seating herself with her back against a great rock, staring downstream. I was well aware that all about us scouts of that company behind watched us.

"We must find a place for night camp." I tried to find a normal subject to discuss with this stranger I found it hard to believe was my sister.

"We shall find one and-" her thoughts were silent. Then she added, "If all goes well, we shall discover thereabouts what is most needed. But there is no time to linger now."

Already she was on her feet, striding away up the cut above the pool. As I tramped after her I suddenly saw, in the soft earth of the bank, the print of wedge-shaped feet, the toes only marked by faint indentations. As I had learned to know them-Krogan! They led from the pool, away from water, which puzzled me.

Orsya? But I could not be sure of that. If the Krogan had allied themselves with the Shadow as they may well have done by now, then any one of them could be among that company now ranging behind us. Only, why away from water? That was the one thing they dreaded more than anything else. I saw no other prints to suggest that this wayfarer had been a prisoner, nor even if he or she had been hunted, and thus forced into dry country.

The marks were to be seen now and again in patches of dry soil, smudged but still unmistakable. A Krogan, apparently deliberately, climbing the same way, against all nature and custom. Twice I knelt to examine them more closely, certain I must be mistaken. Once I touched sword point into one to see if the runes would tell me anything. This might be an illusion meant to deceive. But the runes did not light.

It was growing fast into twilight when we came into a narrow dark cut leading upward and Kaththea went into it without faltering. I saw the prints here also, but something made me believe that the maker now walked with difficulty. Was there water ahead? If so, I trusted that the straggler from the river had managed to reach it.

Then I saw in the deep gloom a tiny spark of white fire. It could be nothing but Orsya's horn-rod, set up as she had before, for protection against the evil roaming here. But Orsya away from water-why?

"Because we have need of her, brother!" Kaththea's thought reached me for the first time in hours. "She gave of her magic in this scarf-and that can be a two-way road. Having put something of herself into it, I could reach her so-now she waits us."

"But she is far from water, and she is Krogan. She must have water!"

"Do not worry; she shall have all she needs when we reach her."

I was aching tired but I ran now, stumbling into rocks which choked this place. Then I came to where stood the unicorn horn with its taper of protection. By it lay Orsya. She moved feebly as I dropped on my knees beside her. Water-but I had no bottle of that precious fluid. Could I take her back, down the broken land, to the pool where I had seen her prints first? It would be almost hopeless to try, but if there were no other way of saving her, that I would do.

"It is not necessary." Kaththea stood there, gazing down at the two of us, "What needs to be done can be done here and now."

"There is no water, and without water she will die." Kaththea was slowly unwinding the scarf. Orsya's head turned a little on my arm. I had an impulse to lift my hand, to cover her eyes so that she could not look upon the monster my sister had become.

"Monster-yes."

I was ashamed that my sister had caught that thought "But now we have the remedy-that which you can do for me, Kemoc. As I know you will-you will-you will-" She repeated the words in my brain with a beat, and I found myself agreeing that what she wanted would be done.

"Take that good sword of yours, Kemoc, and give me blood-blood to wash away ensorcelment, to be Kaththea again."

"Blood!" I was startled out of my acquiescence.

"Blood!" She leaned closer, stretched out her paws. "Kill the water wench; let me have her blood! Or would you have me half monster all the rest of my days?"

Then she spoke other words, meant to bind and command, and I raised the sword. On it the runes blazed high and the hilt burned my hand. I looked to Orsya and she gazed at me, though she made no plea for mercy, nor was there any fear in her large eyes, only a kind of patient waiting for what she could not escape.

I cried out, rammed the point of the sword into the earth so it stood quivering between Kaththea and the two of us. And I heard Kaththea cry in answer. This time not with her mind but aloud, it being so terrible I shuddered. In it I heard that moan of one betrayed by him upon whom she had the greatest right in the world to trust. Her anguish cut through the Kaththea who now was, to reveal the Kaththea who had once been. She cowered away from us covering her face with her forearms.

I laid Orsya back on the ground and reached for the sword hilt.

"If you must have blood," I began and raised that blade to my own flesh.

But she did not listen. Instead she laughed, that terrible, lost laughter. Then she ran away from us, back into the dark. But her thoughts still reached me.

"So be it! So be it! I shall make another bargain. But perhaps it will not be so simple, and you shall rue it even more, Kemoc Tregarth!"

XVIII.

I WOULD have gone after her, but Orsya caught at my ankle, so that I tripped and fell. She held tightly, and, when I writhed around to free myself by force, she cried out: "I do this for you, Kemoc, for you! She is no longer what you think her. Now she would lead you straight into their hands. Look upon your sword!"

I was loosening her hold finger by finger. Now I glanced to the sword which had fallen from my hand, and which now lay, point out into the dark. Never had I seen those runes blaze so fiercely.

"It is Kaththea out there!" I loosed the Krogan girl's hold. "And we were followed by forces of the Shadow."

"She is not the Kaththea of your knowing," Orsya repeated weakly. Her eyes closed, and she forced them open again with what was manifestly a great effort. "Think you, Kemoc; would she to whom you have been bound ask you to do what she did?"

"Why-why did she?" I had my hand on the sword hilt. But I was no longer so driven by the need to follow Kaththea. Thought had returned to me.

"Because it is true. Blood is life, Kemoc. Among the half-people, hunters drink the blood of the bravest of their kill, that they may have the life force and courage of those they have vanquished. Do not warriors mingle their blood, that henceforth they may be brothers?"

"Among the Sulcarmen they do."

"Wherever your sister has been, she has been marked. She cannot be whole and herself unless blood draws her back entirely to this world again. Kemoc-your hands!" She was staring at my paws. I held them closer to her unicorn candle for her viewing.

"As she is marked, so am I. It is worse for her. To be a fair maid, and then look upon yourself as-that! It is enough to drive one mad!"

"Which is also true." Orsya's reply was but a whisper. "She put the drawing spell on me, did she not?"

"Yes."

I looked from my paws to the Krogan girl, roused from my thoughts. Water-Orsya would die if she had no water. If I followed Kaththea, Orsya would die in this desolate place as surely as if I had done as my sister demanded. If I could not kill Orsya by sword stroke, still less could I leave her to die more lingeringly.

"Water . . . ?" I looked dully about me as if I expected to see it gush forth from some rock at my saying of the word. "The pool-back there," I added, though I thought that was hopeless. Even if I could find my way back in the dark, carrying Orsya, she might well die before we reached there. If we were able to escape being pulled down by that monstrous army . . .

Her thoughts whispered faintly in my mind: "Over Heights-"

I looked up the cut. Such a climb-in the dark . . .

She struggled feebly, reaching out her hand for the horn. When I would have taken it up for her, she roused to refuse me.

"No . . . if you touch it . . . virtue departs . . . Hold me . . . to take it."

I supported her until her feeble fingers closed about the horn. Then I fastened the sword to my belt and got to my feet, gathering her up in my arms. The horn lay upon her breast and the light from it was no longer a narrow candle but a radiance which showed something of the path ahead.

That night was our time of fear, despair, struggle, endurance. Somehow Orsya held to life, and I kept going, carrying her. Now and then the sword would blaze, but I dared not wait to see what followed. The sky was dawn-gray when we came through a pa.s.s, blundered through. We looked down into wild lands. Somewhere, farther on, might lie the Valley. But for us both now there was only one need-water.

"Water-" It was not a plaint, that word from Orsya, but, I realized with an inward leap of hope, recognition!

"Left, now-"

I wavered to the left, downslope. Brush tore at me and my burden, and I was so weak with weariness that, had I fallen then, I do not believe I could have come again to my numb feet. But when I did stumble forward, it was near a small cup into which fed the merest thread of spring.

Laying Orsya on the ground, I used my paws to splash and throw that precious liquid into her face, along as much of her body as I could. When she stirred I could have shouted aloud my relief. Then I pulled her closer to that small basin, and she plunged her head and as much of her shoulders into it as she could, lying there unmoving as she soaked it into her skin, regaining so its vitalizing energy.

Then she raised her head and sat up, to put her feet into its freshness. This was an act of magic as great as I had ever seen, for the body which had been so light and withered as I carried it, grew firm and young again under my eyes. I half lay now on the opposite side of the pool, sure she could care for herself, so drugged with fatigue that I could not have kept from sleep if Dinzil himself had appeared before me.

I awoke to a kind of singing in which there were sounds which might be words but which I did not understand. The hum was soothing, and held off any terrors night in these haunted wilds might hold-for it was the dark of night which I saw when I opened my eyes. Orsya, much as she had been when we journeyed into the land of the Dark Tower, sat there, facing her candle-horn, holding out her hands to its light as one warms oneself at a fire.

But when I remembered the Dark Tower, then there returned to mind all else, so the content of those first moments was lost. I sat up abruptly, looking over my shoulder, for we were still in the cup of the pool and behind us the Heights from which we had come, wherein Kaththea might still wander lost.

"There is no going back!" Orsya came to me. As she had done to show me Kofi, she knelt behind me and put her hands upon my temples. So I "saw," that the land behind us was a-crawl with the forces of the Shadow, that they were uniting for some great thrust. I knew without her telling that the thrust would be at the Valley. My allegiances, so long divided, I still could not reconcile. I was torn two ways-Kaththea and those to be warned.

"This is not the moment, nor the hour, nor the day, on which you can stand battle for Kaththea. If you return into that cauldron of danger, then you shall have wasted your strength and what gifts you have for naught. Indeed, you may do worse; did not Dinzil hint that in you he might find yet another tool? Will he not be more inclined to try that since he can no longer control Kaththea? You might be a rich prize-" Orsya reasoned.

"How know you what Dinzil said to me?" I interrupted.

"While you slept you dreamed, and while you dreamed, I learned much," she returned simply. "Be a.s.sured, Kemoc, your sister has stepped beyond the limits where you can call to her."

"There are powers; they can be sought." I closed my mind, or tried to, to that fear.

"But not by you. You know too little to be properly on guard; you might lose too much. Now must be your choice: Throw away all by going back, or take your warning to the Valley."

She was right, but that did not make her words any easier to accept. I had failed, and for the rest of my life I must live with that failure. But, matters now going as they seemed to be, that life would probably not be long. Best spend it doing all I could to withstand the Shadow.

We had to keep to water, which made us vulnerable. Yet I would not do as Orsya urged and leave her to follow alone. I knew too well what might happen to her. I had lost Kaththea through ignorance-for I might have given her my own blood and so won her back-but I was not going to be responsible for Orsya's loss also.

She kept the horn tight against her. It glowed still and gave us light. And, she told me, it had other properties for our protection. But I disliked using it, for power draws power, even if they are of opposite natures.

At dawn we huddled in a niche between two large boulders. The thin rill we had followed from the pool linked here with a larger stream and first Orsya lay long beneath its surface, drawing restoration into her. Once we roused from uneasy dozing, hearing a ring of hooves on stone. I pushed into a crack from which I could see below. Men rode there-not on Keplians, but on Renthans. They might be a scouting party from the Valley, was my first thought, until I saw their banner and read the device on it as one borne by a follower of Dinzil.

But they would be welcome in the Valley, thus opening a door for their fellows. . . . In me now was born a need for speed, to deliver the warning. Orsya's hand touched my paw.

"They ride from, not to, the Valley," she said. "But it is true that times grows short for all of us!"

How short we realized as we moved on. Twice we crouched in hiding as parties of the enemy went by. Once some shadowy things which glowed and left a putrescent odor on the air; then, three Gray Ones who loped with a fast, ground covering stride.

Orsya found food for us, things which she routed from under stream rocks and which I crammed hastily into my mouth and tried neither to think on or taste, as I manfully chewed and swallowed. We kept to the stream which luckily ran in the right direction. Shortly before sundown Orsya pointed to a vee of ripples.

"Kofi?"

"No, but another of his people. Perhaps he has news for us."

She trilled and twittered as she had with Kofi, and then turned to me with a slight frown.

"The forces of the Shadow are spread widely between us and the Valley. They await some word for attack."

"Can we pa.s.s them?"

"I do not know. You swim, but not well enough to take the deep ways."

"If I have to, then I shall. Show them to me," I told her grimly.
