The people of the Ma'a-mbai were tall and dark. They had the darkest skin Aeriel had ever seen, a dusky rose hue the color of cinnamon. They wore loose, sleeveless smocks of pure white seedsilk and carried long, knobbed walking staves. They owned few possessions, spoke softly to each other as wind among reeds, and their hair grew close to the scalp in coarse, tight curls.

They were nomads, Aeriel discovered, combing the desert for game and other foodstuffs.

That they had taken away her torn and bloodied kirtle and given her one of their own garments, Aeriel realized the first time she had awakened clearheaded enough to take in her surroundings.

Their leader, Aeriel learned, was called Orroto-to - a tall, spare woman of middle years and few words. She tended Aeriel's wound with poultices and herbal broths. At first Aeriel slept much, but gradually, as Solstar rose toward its zenith and Oceanus waned, she felt her strength beginning to return. And the Ma'a-mbai bore her along with them as they moved east.

At one point, after much travel and little resting, the Ma'a-mbai laid their camp next to a stony wall, drove their staves into the sand, and hung their canopies from them. Aeriel they laid in the shade of one of these, and Orroto-to knelt beside her, feeding her choice bits of a roasted desert hare. Aeriel turned to her; she was feeling well enough for conversation.

"The desert cannot hold much food," said Aeriel.

Orroto-to tore off another tender bit. "There is enough," she said.

Aeriel savored the taste of the morsel in her mouth. "Still," she said, "there would be more for your people if I were not here." She had not touched the duarough's velvet pouch - now worn on a thong about her neck - since she had been with the desert folk.

Their hospitality did not permit a guest to draw upon her own provisions.

The desert woman checked the poultices on Aeriel's throat and added a few drops of water from a shallow dish on the sand beside her. "The Pendarlon has asked us to see to you," she said, "and that is enough."

"The Pendarlon?" said Aeriel, puzzled. "Who is that?"

Orroto-to gave a throaty laugh; her wise, pale brown eyes danced. "You do not know? He is the one who rescued you."

Aeriel gazed at her, surprised. "The lyon?" The other nodded. Aeriel glanced down. She had occasionally heard the people of her village exclaim oaths of "By the Pendarlon," but she had never used the expression herself. "But," she said at the last, "what does it mean?"

"Pendar-lon," her physician explained. "It means 'Warden of Pendar.' " That her voice held no rancor encouraged Aeriel to inquire further.

"And where is Pendar?" she asked.

Orroto-to looked at her in surprise. "Why, this," she exclaimed with a nod that took in everything around them. "All that you see about you to the horizon and beyond."

"But I thought," said Aeriel, "I thought that Pendar was a great land of cities and ancient wisdom. Talb said the Old Ones lived in Pendar."

The desert woman nodded sadly, offered Aeriel the last morsel, but Aeriel shook her head. She had eaten enough. "Once, little pale one, once. Their glory is all laid waste now." She fed the tidbit to one of the thin, sandy camp dogs and washed the grease from her dark fingers in the shallow bowl. "The Old Ones are few and far between. They are growing afraid of the outside - most of them hide in their domed cities now, far from each other, shut off from the world." She shook the water from her hands and waved them slowly to dry. "They come out so seldom now that most of your people think they all died years ago." The wisewoman shook her head. "Not so. You should know better."

"What does the Pendarlon do?" inquired Aeriel.

"Ah," said Orroto-to, "he runs back and forth over the land, guarding the borders and looking to the safety of his people."

"Who are his people?" said Aeriel.

The dark chieftess gave another low, throaty laugh and gestured toward the Ma'a-mbai youths filling their waterskins at the well. "We are his people," she said. She looked up at two skyhawks circling lazily in the black heavens. "Those are his people." She nodded toward a dune where three sand-rats scampered and played. "There are his people," she said, "and there." In the distance a herd of gazelle leapt and bounded like tumblers.

"Every creature within his borders is one of his people," Orroto-to said.

"He is your ruler, then," said Aeriel, but the dark woman shook her head.

"He does not rule us. No one can rule us. No one can rule anyone who does not first agree to the ruling." She smiled a trace at Aeriel and patted the little camp dog, which was whining for more tidbits. "One must rule oneself."

"But," began Aeriel, puzzled, "but if the Pendarlon..."

"He is our warden and our guide," the chieftess told her, "and everyone is free."

Aeriel shook her head, still not understanding. "But do you, Orroto-to, not rule the Ma'a-mbai?"

"I but lead them," the other replied, "and they follow only so long as they choose."

Aeriel considered it for a long moment, then, and did not understand. "But what am I now?" she asked finally. "Now that I am within the lyon's borders. Have I, too, become one of his people?"

"No," her companion answered, getting up from the sand and shooing the small dog away. "You belong still to the Avarclon, though you are the leosol's guest and under his protection now."

"And who is the Warden of Avaric?" asked Aeriel. She had never before heard of an Avaric-lon.

"The Starhorse," said the other, straightening. "The equustel."

"The equustel," cried Aeriel, sitting up suddenly. "But I am going..."

The chieftess nodded. "Yes, the Pendarlon has told me. And he has said he will return to aid you."

"When?" cried Aeriel, reaching out to stay Orroto-to from going. "When will he return?"

"When you are healed," the woman answered. "Lie down now and rest. I must go work on the new walking stick I am carving, and you must not disturb the poultice on your neck." Then she turned and ducked gracefully out from under the canopy.

"How long?" insisted Aeriel. Already her head swam from sitting.

Orroto-to paused and turned, gave a slight shrug, and shook her head. "He comes when he comes," she replied. "He did not say how long. Rest now, little pale one, and patience.

You must wait."

Aebiel waited. The Ma'a-mbai moved by day with only brief stops for rest and water.

Solstar slowly reached its zenith and descended, set. The Planet waxed. As nightshade settled down, the Ma'a-mbai made camp and lived off their stores, wove, mended tools, and sang stories. They were great singers of tales beside their white fires, some reciting ancient verses while others blew on soft woodwinds or tapped their walking sticks and tambours. Aeriel heard strange tales of all the peoples of the world, and of ancient days on Oceanus as well.

But her favorite was a desert tale, the song oftheYouth-Who-Tried-to-Give-Up-His-Walking-Stick. But every time he pretended to forget it and left it behind, it came skipping and jigging over the sand in pursuit. Until it had rapped him soundly on the head three times, shouting, "What are you doing? Don't you know I am yours? If I did not run after you, you'd just have to come back and find me!" - this until the youth learned that some things it is wise not to lay down. Hearing this tale by the cookfires late that first fortnight, Aeriel had laughed till her sides were sore.

At last long nightshade passed and Solstar rose. The Ma'a-mbai took up their wandering again. The wound on Aeriel's neck had healed over in a smooth, white scar and she found herself able to walk with the train the length of each march without tiring. Orroto-to gave her a carved walking stick then and taught her to stalk the cautious desert creatures: hares and deer and dusthens.

Soon Aeriel could throw deftly enough to fell quarry at ninety paces - giving her staff, when she launched it, that peculiar flick of the wrist which the chieftess had shown her, a flick which caused the arcing shaft to reverse itself with a snap in midflight, bringing its heavy, knotted crown down in a hard, swift stroke. After that Aeriel brought what game she could to the cookfires, and no longer held back when sharing in her hosts' food.

Solstar rose and set three times while Aeriel remained with the Ma'a-mbai. The days were long, the nights cool and pleasant, but at last she grew weary with the waiting. A change had overtaken her in the desert where all is patience and peace. She felt fitter, freer, stronger, surer. And her body was losing some of its youthful boniness. For the first time she felt she was beginning to resemble a maid beneath her kirtle, and not a stick-doll made of spindletwigs.

There were other changes, too. Once she had remarked to Orroto-to, "Chieftess, are you darker than when I first came?" and the woman had laughed, saying, "No, but Solstar is burning you pale." And another time Aeriel had asked her, "Orroto-to, are you shorter than when I first met you?" but again the chieftess laughed. "No, little one. You are growing taller."

But time fast was fleeting away. Aeriel had been all of three day-months with the Ma'a-mbai, and in another two, the icarus would fly to find his final bride. Dawn was coming up for the fourth time since she had left the castle of the vampyre, when she said to the leader of the desert people, "I am going. I can wait no more on the Pendarlon. If I must find the Avarclon myself, so I must. Even now I may be too late."

Orroto-to nodded and gazed at her with her wise, dark eyes. "You are free," she said.

"You must do as you must. If your walking stick has been lying too long, you should take it up again, and go where it leads. I will send the Pendarlon after you, when he comes."

Aeriel could think of no word for thanks. The chieftess nodded to her slightly, the only gesture of farewell her people had, then turned back to the Ma'a-mbai. Their procession began slowly to move on. Aeriel raised her staff to them, then turned north toward Oceanus, and began to walk. She had not been walking many hours when she heard the padding of paws in the sand behind her.

She turned as the Pendarlon bounded up beside her.

"You are an impatient one, daughter," he said. "I sought the Ma'a-mbai only to find you gone."

"Why did you wait so long to come?" Aeriel asked him as he fell into walking slowly beside her. "My wound healed all of two day-months ago."

"That is not the only wound you were healing of, daughter," the leosol replied. "But if you are fully rested now, I will take you to the Avarclon."

Aeriel nodded; the lyon bowed his head and she saw she was to mount. Putting her wrist through the braided loop at the head of her walking stick and adjusting the thong of the black velvet bag about her neck, Aeriel rested her hands on the Pendarlon's shaggy shoulders and slid onto his back.

"Hold to my mane, now," he said, and with a great bound, they were off across the dunes swifter than a greyhound. The lyon ran in bounds so long and smooth there was no jolt at all when he touched the ground and sprang again. Aeriel held to two great hanks of his fiery gold hair, which was silky and soft as satinflax.

The horizon rose and dipped at every stride.

The lyon was running straight for Oceanus, which ascended slowly but visibly. Aeriel at length grew tired of sitting and, her arms wrapped tight around his massive neck, she lay down along his back and closed her eyes. Perhaps she slept.

They ran for hours over the dunes. Rested, Aeriel pulled herself into a sitting position on the lyon's back again. Later, she ate and slept again. The leosol never slackened his pace or paused to rest. They ran past the ruins of fantastic domed cities - dark as burned-out lanterns, their domes cracked and scored with age. Once, on the far horizon she thought she saw one city that was alight, but it disappeared from view as the Pen-darlon touched down, and she could not find it again when they once more rose into the air.

They ran past the bones of great animals long dead - even their skeletons were oxidizing and falling into powder. They ran past living animals, too - little lithe antelope, and great, shaggy double-humped camels. Several times she spotted kites, sailing slowly overhead, and at one point a pair of four-footed creatures watching her and the leosol intently from far away.

They looked like long-legged, huge-eared dogs with hairy tails, but when Aeriel mentioned them to the lyon, asking what they were, he merely glanced over his shoulder at them, rumbled low and darkly, once, then quickened his pace. The spotted dog-creatures loped away to the northwestward and disappeared. Aeriel forgot about them as she caught sight of a caravan to the west - a long line of riders and pack animals snaking over the dunes.

And once they passed very close to the camp of desert wanderers much like the Ma'a-mbai, save that their loose, sleeveless smocks were of pale blue instead of white. From them went up a great shout when they sighted the Pendarlon from afar. They chanted and waved their lank, knobbed walking staves, while the youths and maidens began an homage dance - bowing low to the ground and trilling a long, high song. The leosol roared mightily in answer, but never slackened his pace. Aeriel watched them recede in the distance, and their chanting and trilling hung in her ears for a long time after.

Oceanus rose higher in the heavens. The hours drifted by. Earth shrank to a fingernail crescent as the sun ascended toward its noon eclipse. Aeriel slept again, and ate from her food-sack. She lost count of the times she ate and slept. The lyon never tired.

But at last, at last when the Planet hung at zenith in the star-crowded sky and Solstar was just nudging at its side, then the lyon's gait began to slacken. His breathing was as quiet and steady as ever, but he ran more leisurely now; Aeriel knew they were nearing the Avarclon. She looked for him, and listened. The last of the sun slid into eclipse.

And then she saw him across the dunes. He was of dark silver, fiercesome and free, with a keen horn on his forehead and two great wings upon his shoulders; there were little wings upon his fetlocks, and beneath his ears behind the cheeks. He galloped toward them over sandhill and dune, then pitched to a standstill, snorting and stamping the ground. He let go a wild whinny that pealed like a bugle blast. The lyon came smoothly to a stop and roared in answer. The sound thundered like mountains shifting, rolling far and away, off into the distance over the dunes.

Oceanus hung huge and umbrous in the sky. The hiding sun made a bright hallow around it. Avarclon and Pendarlon faced each other across the sand and cried their greetings. The darkened sun stood so directly overhead that neither of them cast any shade. Aeriel slid from the lyon's back and laid her walking stick on the sand, stood beside the great cat beneath the eerie half-light of noon.

"How are you, my old friend?" cried the leosol.

"Well enough, considering," the starhorse replied. "And who is this you have brought with you? It has been many a day-month since last I saw any living creature but yourself."

Aeriel folded her hands and bowed, as she had been accustomed to do before the satrap whenever he had come to the syndic's house to visit his half-sister. And breathing deep, Aeriel caught a keen, clean scent like oil of silvermint. "My name is Aeriel, my lord," she said, "and I come from the castle of the vampyre___"

She got no further, for at the mention of the icarus, the starhorse shied and whinnied as if challenged. Aeriel was too startled to continue.

"Go on," the lyon told her quietly. The starhorse was, it seemed, as fierce and skittish as the leosol was strong and steady.

"Talb the duarough sent me," said Aeriel. "I do not know his real name."

"Ah, the Little Mage of the Caves of Down-wending," the equustel said, tossing his head and snorting. "So he did not go with the queen to Westernesse. Had I known I had such an ally in the plains, I might have called on him at need. Tell me, little one, why have you come?"

"He has sent me," said Aeriel, "to sing you a rime he has found in the Book of the Dead.

He says you will know the meaning thereof."

The starhorse nodded, champing and sidling restlessly. "Sing me the rime," he said.

Aeriel told him:

"On Avaric's white plain

where the icarus now wings To steeps of Terrain

from tour-of-the-fdngs,

And damoiels twice-seven

his brides have all become:

Afar cry from heaven

and a long road from home -

Then strong-hoof of the starhorse

must hallow him unguessed

If adamant's edge is to plunder his breast.

Then, only, may the Warhorse

and Warrior arise To rally the warhosts, and thunder

the skies."

The equustel nickered softly and grew suddenly gentle. Beside her, Aeriel thought she caught the faint rumbling of the lyon's purr.

"Yes, child, yes," the starhorse exclaimed. "I have heard that song before. It was one of the riddles sung over me at my making. I know its meaning well."

"Your making?" said Aeriel in wonder. "Are you not mortal? Were you not born?"

The starhorse laughed, whinnied and shook his head for sheer exuberance. "The Old Ones made me, child, and the lyon, and the hippogriff of the eastern steeps and the gryphon of Terrain - and the great she-wolf of forested Bern, and the lithe serpent of the Sea-of-Dust." His eyes grew bright and far; he breathed deep. "Made these and the other Wardens-of-the-World. Ravenna, Ravenna! She was a wise woman."

The Pendalon had sat down purring on the sand near Aeriel, began nibbling and licking his paw. The equustel reared and danced where he stood.

"Ravenna?" ventured Aeriel. "Who is Ravenna?"

The Avarclon whinnied fiercely and the sunlion roared.

"Ravenna, Ravenna, the Ancient who made us," the starhorse replied. "When I was but a fledgling foal and the Pendarlon a cub, and all the other Ions but hatchlings or whelps, then she sang over us a song for each - a destiny to strive after. It would come to pass, she said, if our hearts proved true enough and fate ran fair." The Avarclon rose and pawed the air with his hooves; his great grey wings beat like a bird's. "Oh, she was learned, and steadfast, and kind. She foresaw the great changes that were to pass - even the coming of the icari, and how they might be undone."

"Tell me of the Old Ones," Aeriel begged him. Curiosity burned in her to know.

Then the Avarclon nodded and Aeriel sat down on the sand near the leosol to listen, while the starhorse spoke to her of ancient days, of the coming of the Ancients into the world, plunging across the heavens from Oceanus in chariots of fire, how they brought air and water and life to the land, bred plants and made creatures to populate it, then fashioned all the peoples of the world. Aeriel was stolen away with wonder at his tale, and the starhorse seemed to grow more beautiful and spirited as the eclipse reached its fullest.

But then he spoke of great wars and plagues on Oceanus, of the departure for their homeland of all but a few of the Heaven-born. Then the chariots ceased coming, and gradually the land began to change; most of the water ran off into the ground and the atmosphere began to thin. Species of plants and animals died out. One by one, the Ancients sealed themselves off in their domed cities and refused to have more to do with the slowly dying planet. Left to themselves, the people fell into tribalism.

Ravenna had been the last to go, to disappear into her domed city, sealed away from further commerce with the world. But before she had gone - and she would not say why she was going - she had fashioned the wardens, more than a dozen of them, to watch over the various quarters, protecting the people and keeping the peace until such time, lost far into the indefinite future, that she had promised to return.

And the wardens had kept their ranges well for almost a thousand years - until the coming of the icari. No creature seemed able to stand against them. Six Ions already had fallen to the six that had come so far, and now this last, the seventh, was in Avaric. And when he joined their ranks as a true vampyre and made their number complete, it was said, then they meant to fly in force against the other kingdoms, and take all the world in their teeth.

And to Aeriel, swept away by the starhorse's words, it seemed for a moment that her heart was no longer her own. She sensed the equustel's cold hatred for the vampyre and his brethren, the sun-lion's more heated ire. She felt the same outrage well up in her own breast against the icari - be they ever so fair - as at last she comprehended the full malevolence of their intent. She stared at the starhorse in dismay. "But why have you abandoned Avaric to the darkangel?" she cried.

The Avarclon gave a low horse-laugh that sounded bitterly amused. "Daughter, you speak as though you believe I gladly left. Child, I am exiled unwilling. Do you not think I would return to vanquish the vampyre if I could?" The greathorse shook his head. "He has proven too strong for me, and my fate is left unfulfilled." He gazed off across the rolling dunes toward Avaric. "Though neither could he destroy me, nor would I let him catch me to enslave me - so he has driven me out with his terrible might."

The words had greatly saddened him. He paused for breath. Above them, the eclipse was nearing its close. In a moment, Solstar would peer from behind the Planet.

"But now," said Aeriel, "the time is ripe. Soon he will take his fourteenth bride and be master absolute of the plain. You must come back with me. Is it not written that by the hoof of the starhorse the vampyre shall fall? Come back with me."

The Avarclon shook his head slowly. He looked visibly weaker than he had only a few minutes before. His head drooped. His coat no longer shone. He seemed to grow gaunt before her eyes.

"If only I could, child," he whispered, his voice growing thin and hoarse. "If only..."

The rim of the sun slid from behind Oceanus. Light spilled over the dunes. The Avarclon gave a low moan of despair. His eyes were dull and glazed. His flesh shrank and melted away beneadi the skin. Aeriel saw his bones.

"What is it?" she cried sofdy. "What is happening?"

"Hush, child," said the lyon. "He cannot hear you now."

The starhorse moaned again and shuddered. "Avaric!" he cried. "Avaric, Avaric!"

His legs grew stick-thin and buckled. He pitched forward onto the sand. Aeriel gasped and pressed closer to the lyon.

"Tell me what is happening," she begged him. "I'm afraid."

The grey horse struggled to rise. His wings thrashed desperately. His legs folded under him like a newborn colt's. His second attempt was weaker. His third weaker still. His wings ceased beating. He gave a deep sigh; his head bowed slowly, slowly till his nose just touched the ground. His rib cage heaved and his breath stirred the sand.

"Each of us," the lyon said, "each of the wardens is bound to the lands we ward. None of us can spend many day-months from our domains without.. .**

Aeriel hardly heard the rest. Solstar was halfway out from behind the Planet. The starhorse aged before her eyes. He no longer struggled to rise, or even to keep his head up, but just to keep himself upright. He swayed, righted himself, swayed again. At last he lost the battle and rolled slowly over on his side. His long, graceless legs kicked, writhed; his head moved feebly in the sand. His jet eye stared at the sky above. Aeriel could see white Solstar reflected in it.

Then his eye darkened, and even the reflected light in it went out. He lay still. His flesh moldered and crumbled. His moth-eaten skin hung in rags from the bone. The tatters sagged in the slight wind, tiny pennants. Then they, too, were gone and only the hard things were left - teeth, bones, hooves, and horn, and a few strands of his mane and tail, and the feathers of his wings. The desert wind sighed softly; some of the feathers drifted away across the dunes.

"He is dead!" cried Aeriel, unable even now quite to believe it. "Why did you do nothing?

What killed him?"

"Exile killed him. He tried many times to return to the plains. Each time the vampyre drove him back at the border. He has not set hoof in Avaric for twelve years."

"He has been here twelve years?" said Aeriel. "But I thought..."

The lyon nodded. "It is just as I said. He has been dead twelve years."

"But," Aeriel began, "I saw him living----"

The Pendarlon shook his head. "Daughter, have you never heard that phantoms walk at noon?"

Aeriel looked at the heap of bleached bone on the dune before her. The slight desert wind breathed soft against her skin, lifted her hair. She gazed at her feet. She felt empty of a sudden, and utterly alone. Her quest had failed; the starhorse was dead. She heaved a little sigh, felt starved for air. Her heart hurt; her throat hurt.

"Then it is hopeless," she whispered, "and it was hopeless from the first. Why did you not tell me at once that he was dead?"

"Because it makes no matter," said the Pen-darlon.

"No matter?" cried Aeriel. "The starhorse is fallen. He cannot come back with me. Now the darkangel can never be vanquished, and I cannot save his wives. All is lost, and I have failed."

"Nothing is lost," the lyon said, "nor have you failed. Sing me the rime again."

Aeriel did so, repeating it dully:

"On Avaric's white plain

where the icarus now wings To steeps of Terrain

from tour-of-the-kings,

And damoiels twice-seven

his brides have all becomes

Afar cry from heaven

and a long road from home -

Then strong-hoof of the starhorse must hallow him..."

She was midway through the third coupling when the Pendarlon stopped her. "There.

That line. Say it over."

Aeriel drew breath and started to repeat it. " 'Then strong-hoof of the starhorse must...' "

"Ah, child," the lyon cried, "do you not see? The hoof, the hoof is your prize - not the equustel himself."

Aeriel stared at the warden before her and wondered if of a sudden he could have gone mad. She shook her head to clear it, tried to find her tongue again. "Pendarlon, what do you mean?"

A laugh purred deep in the lyon's throat. "You have but to take his hoof, daughter, and your quest is done."

Surely his manner was not mad, she reflected, uncertainly, though his words made no sense to her. She glanced at the skeleton of the Avarclon. Abruptly, she remembered the duarough's words: "Seek after the starhorse - he of the strong hoof, undying. Bring back what you may of him, for it is by the hoof of the starhorse that the icarus will fall." Bring back what you may of him. At the time she had thought he must mean news.

She stood a moment, indecisive. Could the little mage have meant the horse's hoof?

Aeriel snorted; and yet she had already seen and heard of stranger things. If only he had had time to explain! The Pendarlon sat watching her as she eyed the hooves of the skeleton. Well, there could be no harm, at least, in taking one. Still she felt uneasy.

"I cannot rob the dead," she told him.

"The dead are dead," the leosol replied. "They have given up their bodies. He will not mind that you borrow his hoof for a little. Truly, you may do more good than you know by it."

He started across the dune toward the starhorse. Aeriel hesitated.

"Come, daughter," he said, glancing to northwestward. "We must away before much longer, or I shall not get you back to the border by nightfall."

Aeriel stood a moment, wondered on the direction of his glance. Their way home lay south. She followed him to the scattered bones. Kneeling in the sand, she murmured,

"Which hoof?"

"The forehoof on the near side," said the leosol.

Aeriel grasped it gently and it came off in her hand. The other hooves were dull grey, almost leaden in hue. The one in her hand, however, was bright and gleamed like some precious metal. Aeriel held it cupped in her hand a long moment, gazing at it. "But how?"

she wondered aloud. "What virtue is there in this hoof now?"

"Come, child," said the Pendarlon, with another glance to the western north. "The duarough will know."

Aeriel opened the mouth of her black velvet bag and slid the hoof inside. She drew the mouth closed and let the pouch drop limp and empty-seeming against her breast beneath her smock. Solstar blazed down. Taking her walking stick in hand once more, she turned to the lyon and mounted his back. He wheeled swift as lightning and sprang away in a lithe leap over the dunes. They rose into the air and touched down, rose and touched down. The lyon ran in long, tireless strides, and soon they had left the equustel far behind.
