“We’re in luck. They’re on their way to raid the Tsenakwa, who live fairly close to the Trees of Many Shadows. I explained what we were doing here, though not all of it by any means. They don’t know we’re bucking the Lord himself, and I’m not about to tell them. But they do know we’re on the trail of Chryseis and the gworl and that you’re a friend of mine. They also know that Podarge is helping us. They’ve got a great respect for her and her eagles and would like to do her a favor if they could.

  “They’ve got plenty of spare horses, so take your choice. Only thing I hate about this is that you won’t get to visit the lodges of the Bear People and I’ll miss seeing my two wives, Giushowei and Angwanat. But you can’t have everything.”

  The war party rode hard that day and the next, changing horses every half-hour. Wolff became saddle-sore-blanket-sore, rather. By the third morning he was in as good a shape as any of the Bear People and could stay on a horse all day without feeling that he had lockjaw in every muscle of his body and even in some of the bones.

  The fourth day, the party was held up for eight hours. A herd of the giant bearded bison marched across their path; the beasts formed a column two miles across and ten miles long, a barrier that no one, man or animal, could cross. Wolff chafed, but the others were not too unhappy, because riders and horses alike needed a rest. Then, at the end of the column, a hundred Shanikotsa hunters rode by, intent on driving their lances and arrows into the bison on the fringes. The Hrowakas wanted to swoop down upon them and slay the entire group and only an impassioned speech by Kickaha kept them back. Afterwards, Kickaha told Wolff that the Bear People thought one of them was equal to ten of any other tribe.

  “They’re great fighters, but a little bit overconfident and arrogant. If you know how many times I’ve had to talk them out of getting into situations where they would have been wiped out!”

  They rode on, but were halted at the end of an hour by NgashuTangis, one of the scouts for that day. He charged in yelling and gesturing. Kickaha questioned him, then said to Wolff, “One of Podarge’s pets is a couple of miles from here. She landed in a tree and requested NgashuTangis to bring me to her. She can’t make it herself; she’s been ripped up by a flock of ravens and is in a bad way. Hurry!”

  The eagle was sitting on the lowest branch of a lone tree, her talons clutched about the narrow limb, which bent under her weight. Dried red-black blood covered her green feathers, and one eye had been torn out. With the other, she glared at the Bear People, who kept a respectful distance. She spoke in Mycenaean to Kickaha and Wolff.

  “I am Aglaia. I know you of old, Kickaha—Kickaha the trickster. And I saw you, O Wolff, when you were a guest of great-winged Podarge, my sister and queen. She it was who sent many of us out to search for the dryad Chryseis and the gworl and the horn of the Lord. But I, I alone, saw them enter the Trees of Many Shadows on the other side of the plain.

  “I swooped down on them, hoping to surprise them and seize the horn. But they saw me and formed a wall of knives against which I could only impale myself. So I flew back up, so high they could not see me. But I, far-sighted treader of the skies, could see them.”

  “They’re arrogant even while dying,” Kickaha said softly in English to Wolff. “Rightly so.”

  The eagle drank water offered by Kickaha, and continued. “When night fell, they camped at the edge of a copse of trees. I landed on the tree below which the dryad slept under a deerskin robe. It had dried blood on it, I suppose from the man who had been killed by the gworl. They were butchering him, getting ready to cook him over their fires.

  “I came down to the ground on the opposite side of the tree. I had hoped to talk to the dryad, perhaps even enable her to escape. But a gworl sitting near her heard the flutter of my wings. He looked around the tree, and that was his mistake, for my claws took him in his eyes. He dropped his knife and tried to tear me loose from his face. And so he did, but much of his face and both eyes came along with my talons. I told the dryad to run then, but she stood up and the robe fell off. I could see then that her hands and her legs were bound.

  “I went into the brush, leaving the gworl to wail for his eyes. For his death, too, because his fellows would not be burdened with a blind warrior. I escaped through the woods and back to the plains. There I was able to fly off again. I flew toward the nest of the Bear People to tell you, O Kickaha and O Wolff, beloved of the dryad. I flew all night and on into the day.

  “But a hunting pack of the Eyes of the Lord saw me first. They were above and ahead of me, in the glare of the sun. They plummeted down, those playhawks, and took me by surprise. I fell, driven by their impact and by the weight of a dozen with their talons clamped upon me. I fell, turning over and over and bleeding under the thrusts of flint-sharp beaks.

  “Then, I, Aglaia, sister of Podarge, righted myself and also gathered my senses. I seized the shrieking ravens and bit their heads off or tore their wings or legs off. I killed the dozen on me, only to be attacked by the rest of the pack. These I fought, and the story was the same. They died, but in their dying they caused my death. Only because they were so many.”

  There was a silence. She glared at them with her remaining eye, but the life was swiftly unraveling from it to reveal the blank spool of death. The Bear People had fallen quiet; even the horses ceased snorting. The wind whispering in from the skies was the loudest noise.

  Abruptly, Aglaia spoke in a weak but still arrogantly harsh voice.

  “Tell Podarge she need not be ashamed of me. And promise me, O Kickaha—no trickster words to me—promise me that Podarge will be told.”

  “I promise, O Aglaia,” Kickaha said. “Your sisters will come here and carry your body far out from the rims of the tiers, out in the green skies, and you will be launched to float through the abyss, free in death as in life, until you fall into the sun or find your resting place upon the moon.”

  “I hold you to it, manling,” she said.

  Her head drooped, and she fell forward. But the iron talons were locked in on the branch so that she swung back and forth, upside down. The wings sagged and spread out, the tips brushing the ends of the grass.

  Kickaha exploded into orders. Two men were dispatched to look for eagles to be informed of Aglaia’s report and of her death. He said nothing, of course, about the horn, and he had to spend some time in teaching the two a short speech in Mycenaean. After being satisfied that they had memorized it satisfactorily, he sent them on their way. Then the party was delayed further in getting Aglaia’s body to a higher position in the tree, where she would be beyond the reach of any carnivore except the puma and the carrion birds.

  It was necessary to chop off the limb to which she clung and to hoist the heavy body up to another limb. Here she was tied with rawhide to the trunk and in an upright position.

  “There!” Kickaha said when the work was done.

  “No creature will come near her as long as she seems to be alive. All fear the eagles of Podarge.”

  The afternoon of the sixth day after Aglaia the party made a long stop at a waterhole. The horses were given a chance to rest and to fill their bellies with the long green grass. Kickaha and Wolff squatted side by side on top of a small hill and chewed on an antelope steak. Wolff was gazing interestedly at a small herd of mastodons only four hundred yards away. Near them, crouched in the grass, was a striped male lion, a 900-pound specimen of Felix Atrox. The lion had some slight hopes of getting a chance at one of the calves.

  Kickaha said, “The gworl were damn lucky to make the forest in one piece, especially since they’re on foot. Between here and the Trees of Many Shadows are the Tsenakwa and other tribes. And the KhingGatawriT.”

  “The Half-Horses?” Wolff said. In the few days with the Hrowakas, he had picked up an amazing amount of vocabulary items and was even beginning to grasp some of the complicated syntax.

  “The Half-Horses. Hoi Kentauroi. Centaurs. The Lord made them, just as he’s made the other monsters of this world. There are ma
ny tribes of them on the Amerindian plains. Some are Scythian or Sarmatian speakers, since the Lord snatched part of his centaur material from those ancient steppedwellers. But others have adopted the tongues of their human neighbors. All have adopted the Plains tribal culture—with some variations.”

  The war party came to the Great Trade Path. This was distinguishable from the rest of the plain only by posts driven into the ground at mile-intervals and topped by carved ebony images of the Tishquetmoac god of commerce, Ishquettlammu. Kickaha urged the party into a gallop as they came near it and it did not slow until the Path was far behind.

  “If the Great Trade Path ran to the forest, instead of parallel with it,” he told Wolff, “we’d have it made. As long as we stayed on it, we’d be undisturbed. The Path is sacrosanct; even the wild HalfHorses respect it. All the tribes get their steel weapons, cloth blankets, jewelry, chocolate, fine tobacco, and so on from the Tishquetmoac, the only civilized people on this tier. I hurried us across the Path because I wouldn’t be able to stop the Hrowakas from tarrying for a few days’ trade if we came across a merchant caravan. You’ll notice our braves have more furs than they need on their horses. That’s just in case. But we’re okay now.”

  Six days went by with no sign of enemy tribes except the black-and-red striped tepees of the Irennussoik at a distance. No warriors rode out to challenge them, but Kickaha did not relax until many miles had fallen behind them. The next day the plain began to change: the knee-high and bright green grass was interspersed with a bluish grass only several inches high. Soon the party was riding over a rolling land of blue.

  “The stamping ground of the Half-Horse,” Kickaha said. He sent the scouts to a greater distance from the main party.

  “Don’t let yourself be taken alive,” he reminded Wolff.

  “Especially by the Half-Horse. A human plains tribe might decide to adopt you instead of killing you if you had guts enough to sing merrily and spit in their faces while they roasted you over a low fire. But the Half-Horses don’t even have human slaves. They’d keep you alive and screaming for weeks.”

  On the fourth day after Kickaha’s warning, they topped a rise and saw a black band ahead.

  “Trees growing along the Winnkaknaw River,” Kickaha said. “We’re almost halfway to the Trees of Many Shadows. Let’s push the horses until we get to the river. I’ve got a hunch we’ve eaten up most of our luck.”

  He fell silent as he and the others saw a flash of sun on white several miles to their right. Then the white horse of Wicked Knife, a scout, disappeared into a shallow between rises. A few seconds later, a dark mass appeared on the rise behind him.

  “The Half-Horse!” Kickaha yelled. “Let’s go! Make for the river! We can make a stand in the trees along it, if we can get there!”

  IX

  WITH A SINGLE lurch, the entire war party broke into a gallop. Wolff crouched over his horse, a magnificent roan stallion, urging it on although it needed no encouragement. The plain sped by as the roan stretched his heart to drive his legs. Despite his intensity on speed, Wolff kept glancing to his right. Wicked Knife’s white mare was visible now and then as she came over a swell of the plain. The scout was directing her at an angle toward his people. Less than a quarter of a mile behind, and gaining, was the horde of Half-Horse. They numbered at least a hundred and fifty, maybe more.

  Kickaha brought his stallion, a golden animal with a pale silvery mane and tail, alongside Wolff. “When they catch up with us—which they will—stay by my side! I’m organizing a column of twos, a classic maneuver, tried and true! That way, each man can guard the other’s side!”

  He dropped back to give orders to the rest. Wolff guided his roan to follow in line behind Wolverine Paws and Sleeps Standing Up. Behind him, White Nose Bear and Big Blanket were trying to maintain an even distance from him. The rest of the party was strung out in a disorder which Kickaha and a councillor, Spider Legs, were trying to break up.

  Presently, the forty were arranged in a ragged column. Kickaha rode up beside Wolff and shouted above the pound of hooves and whistling of wind: “They’re stupid as porcupines! They wanted to turn and charge the centaurs! But I talked some sense into them!”

  Two more scouts, Drunken Bear and Too Many Wives, were riding in from the left to join them. Kickaha gestured at them to fall in at the rear. Instead, the two continued their 90-degree approach and rode on past the tail of the column.

  “The fools are going to rescue Wicked Knife—they think!”

  The two scouts and Wicked Knife approached toward a converging point. Wicked Knife was only four hundred yards away from the Hrowakas with the Half-Horses several hundred yards behind him. They were lessening the gap with every second, traveling at a speed no horse burdened with a rider could match. As they came closer, they could be seen in enough detail for Wolff to understand just what they were.

  They were indeed centaurs, although not quite as the painters of Earth had depicted. This was not surprising. The Lord, when forming them in his biolabs, had had to make certain concessions to reality. The main adjustment had been regulated by the need for oxygen. The large animal part of a centaur had to breathe, a fact ignored by the conventional Terrestrial representations. Air had to be supplied not only to the upper and human torso but to the lower and theriomorphic body. The relatively small lungs of the upper part could not handle the air requirements.

  Moreover, the belly of the human trunk would have stopped all supply of nourishment to the large body beneath it. Or, if the small belly was attached to the greater equine digestive organs to transmit the food, diet was still a problem. Human teeth would quickly wear out under the abrasion of grass.

  Thus the hybrid beings coming so swiftly and threateningly toward the men did not quite match the mythical creatures that had served as their models. The mouths and necks were proportionately large to allow intake of enough oxygen. In place of the human lungs was a bellowslike organ which drove the air through a throatlike Opening and thence into the great lungs of the hippoid body. These lungs were larger than a horse’s, for the vertical part increased the oxygen demands. Space for the bigger lungs was made by removal of the larger herbivore digestive organs and substitution of a smaller carnivore stomach. The centaur ate meat, including the flesh of his Amerind victims.

  The equine part was about the size of an Indian pony of Earth. The hides were red, black, white, palomino, and pinto. The horsehair covered all but the face. This was almost twice as large as a normalsized man’s and was broad, high-cheekboned, and big-nosed. They were, on a larger scale, the features of the Plains Indians of Earth, the faces of Roman Nose, Sitting Bull, and Crazy Horse. Warpaint streaked their features and feathered bonnets and helmets of buffalo hides with projecting horns were on their heads.

  Their weapons were the same as those of the Hrowakas, except for one item. This was the bola: two round stones, each secured to the end of a strip of rawhide. Even as Wolff wondered what he would do if a bola were cast at him, he saw them put into action. Wicked Knife and Drunken Bear and Too Many Wives had met and were racing beside each other about twenty yards ahead of their pursuers. Drunken Bear turned and shot an arrow. The missile plunged into the swelling bellows-organ beneath the human-chest of a Half-Horse. The Half-Horse went down and turned over and over and then lay still. The upper torso was bent at an angle that could result only from a broken spine. This despite the fact that a universal joint of bone and cartilage at the juncture of the human and equine permitted extreme flexibility of the upper torso.

  Drunken Bear shouted and waved his bow. He had made the first kill, and his exploit would be sung for many years in the Hrowakas Council House.

  If there’s anybody left to tell about it, Wolff thought.

  A number of bolas, whirled around and around till the stones were barely visible, were released. Rotating like airplane propellers that had spun off from their shafts, the bolas flew through the air. The stone at the end of one struck Drunken Bear on the neck and
hurled him from his horse, cutting off his victory chant in the middle. Another bola wrapped itself around the hind leg of his horse to send it crashing into the ground.

  Wolff, at the same time as some of the Hrowakas, released an arrow. He could not tell if it went home, for it was difficult to get a good aim and release from a position on a galloping horse. But four arrows did strike, and four Half-Horses fell. Wolff at once drew another arrow from the quiver on his back, noting at the same time that Too Many Wives and his horse were on the ground. Too Many Wives had an arrow sticking from his back.

  Now, Wicked Knife was overtaken. Instead of spearing him, the Half-Horses split up to come in on either side of him.

  “No!” Wolff cried. “Don’t let them do it!”

  Wicked Knife, however, had not earned his public name for no good reason. If the Half-Horse passed up the chance to kill him so they could take him alive for torture, they would have to pay for their mistake. He flipped his long Tishquetmoac knife through the air into the equine body of the Half-Horse closest to him. The centaur cart-wheeled. Wicked Knife drew another blade from his scabbard and, even as a spear was driven into his horse, he launched himself onto the centaur who had thrust the spear.

  Wolff caught a glimpse of him through the massed bodies. He had landed on the back of the centaur, which almost collapsed at the impact of his weight but managed to recover and bear him along. Wicked Knife drove his knife into the back of the human torso. Hooves flashed; the centaur’s tail rose into the air above the mob, followed by the rump and the hindlegs.

  Wolff thought that Wicked Knife was finished. But no, there he was, miraculously on his feet and then, suddenly, on the horse-barrel of another centaur. This time Wicked Knife held the edge of his blade against his enemy’s throat. Apparently he was threatening to cut the jugular vein if the Half-Horse did not carry him out and away from the others.
