"No doubt," Vala replied. She looked out across the oceans and said, "There are six now. What are they?"

  "Dugarnn mentioned the Nichiddor, but he had no tune to tell me what they are. Be patient. We'll know soon enough. Too soon, I suspect."

  The gliders had been fastened to the lift-bladders. The pilots got into the cockpits while the "ground" crews fitted the explosive bladder-bombs to the wings. Then the wizard, clad in robes and a mask, passed along the gliders. He carried a double-ankh with which he blessed the pilots and their craft. Between each pair of gliders, he stopped to shake the double-ankh at the ufo and hurl maledictions. Dugarnn became impatient but dared not hurry the wizard. As soon as the last of the twenty airmen had been touched by the ankh and prayed over, Dugarnn gave the signal. The bladders with their white-winged cargoes were released. They soared up and up until they had attained a height of a thousand feet above the island.

  Dugarnn said, "They'll release themselves as soon as the Nichiddor nests get within range. Los guard them, since few will get through. But if the nests can be destroyed. . ."

  "There are eight now," Wolff said. The nearest was a half-mile away. Ball-shaped, it had a diameter of about three hundred yards. The fuzzy appearance had been caused by the many uneven projections of plants. These grew out to conceal the gas-bladders that formed irregular concentric rings. On the surface of the spheroid nest were hundreds of tiny figures. An aerial dung-ball, Wolff thought.

  Dugarnn pointed above him, and Wolff saw a number of small dark objects. "Scouts," Dugarnn said. "The Nichiddor won't attack until the scouts report to them."

  "Who are the Nichiddor?"

  "There's one now, coming down to take a close look."

  The wings were black-feathered and had a spread of at least fifty feet. They sprouted out from the five-foot wide shoulders, below which was a hairless human torso. The breast-bone projected several feet and under it was the abdomen with a human navel. The legs were thin and ended in huge feet that were mainly clawlike toes. A long black feathered tail spread out behind it. The face was human except for the nose. This extended like an elephant's proboscis for several feet and was as flexible. As the Nichiddor swept over them, it raised the proboscis and trumpeted shrilly.

  Dugarnn glanced at Wolff’s beamer. Wolff shook his head and said, "I'd rather they didn't know yet what they're up against. My supply of charges is limited. I want to wait until I can get a number with a single shot."

  He watched the Nichiddor flap heavily away towards the nearest nest. The creatures were undoubtedly the work of Urizen, who had placed them here for his own amusement. They must be human beings-although not necessarily Lords-he had transmuted in the laboratory. They could have been abducted from other worlds than his; some might even be descended from Earthmen. Now they lived a strange life beneath red skies and a dark moon, born and raised on an aerial nest that drifted with the winds of this landless world. They lived largely on fish, which they caught as an osprey catches fish, with their talons. But when they came across a surface or air-island, they killed to eat raw human flesh.

  By now Wolff could see why the nests were going against the wind. The hundreds of Nichiddors on it had gripped the plants in their talons and were flapping their wings in unison. The foul chariot of the skies was drawn by as strange birds as ever existed.

  When the nest had come within a quarter-mile, the wings stopped beating. Now the other nests drew up slowly. Two settled downwards; from these the Nichiddor would attack the bottom of the island. Two others veered around behind the island and then came on the other side. Dugarnn waited calmly until the Nichiddor had set their attack pattern.

  Wolff asked him why he did not order the gliders to attack.

  "If they were released before the main body of Nichiddor came at us," Dugarnn said, "every Nichiddor would rise to bar the way. The gliders could not possibly get through them. But with only a small number of Nichiddor attacking the gliders, we have a chance of getting through to the nests. At least, that has been my experience so far."

  "Wouldn't it be wisest, from the Nichiddors' viewpoint, to eliminate the gliders first?" Wolff asked.

  Dugarnn shrugged and said, "You'd think so. But they never do what seems to me the most strategic thing. It's my theory that, being deprived of hands, the Nichiddor have suffered a lessening of intelligence. It's true they can manipulate objects to some extent with their feet and their trunks, but they're far less manual than we.

  "Then again, I could be wrong. Perhaps the Nichiddor derive a certain pleasure from giving the gliders a fighting chance. Or perhaps they are as arrogant as sea-eagles, which will attack a shark that outweighs them by a thousand pounds, a vicious creature that an eagle cannot possibly kill or, if it could, would not be able to carry off to some surface island."

  The wind carried to the abuta the gabble of hundreds of voices and the trumpeting of hundreds of proboscises. Suddenly, there was a silence. Dugarnn froze, but his eyes were busy. Slowly, he raised his hand. A warrior standing near him held a bladder in his hand. By him was a bowl-shaped stone with some hot coals. He held his gaze upon his chief.

  The silence was broken with the united scream of Nichiddor through their snaky noses. There was a clap as of thunder as they launched themselves from the nests and brought their wings together in the first beat. Dugarnn dropped his hand. The warrior dipped the short fuse of the bladder into the fire and then released it. It soared upwards to fifty feet and exploded.

  The gliders dropped from their lifts, each towards the nest appointed to it. Wolff looked at the dark hordes advancing and lost some of his confidence in his beamer. Yet, the Ilmawir had beaten off attacks by the Nichiddor before-although with great loss. But never before had eight nests ringed the abuta.

  A great-winged white bird passed overhead. Its cry came down to him, and he wondered if this could be an eye of Urizen. Was his father watching through the eyes and brains of these birds? If so, he was going to see a spectacle that would delight his bloody heart.

  The Nichiddor, so thick they were a brown and black cloud, surrounded the island. Just out of bowrange, they stopped advancing and began to fly around the island. Around and around they flew, in an ever-diminishing circle. The Ilmawir archers, all males, waited for their chief to signal to fire. The women were armed with slings and stones, and they also waited.

  Dugarnn, knowing that it would weaken them to spread out his people along the top of the walls, had concentrated them at the prow. There was nothing to prevent the Nichiddor from landing at the far end. However, they did not settle down there. They hated to walk on their weak legs.

  Wolff looked out at the gliders. Some had dropped below his line of vision to attack the two nests below the underside. The others were coming down swiftly in a steep glide. A number of Nichiddor rose from the nest to meet them.

  Two fliers passed over the nearest nest. Small objects, trailing smoke, dropped from them and fell on the nests. Females, flapping their wings, scrambled towards them. Then, there was an explosion. Smoke and fire billowed out. Another explosion followed.

  The two gliders pulled up sharply. Carried upward by the momentum of their steep dives, they turned and came back for another and final pass. Again, their bombs hit. Fire spread through the dry plants and caught and enfolded some of the giant gas-cells. The females screamed so loudly they could be heard even above the wing-beatings and trumpetings of the circling horde. They rose from the burning nest, their infants clutched in their toes. The entire nest blew apart, catching some of the females, burning them in flight or hurling them head over heels. Infants dropped towards the sea below, their short wings ineffectively flapping.

  Wolff saw one mother fold her wings and drop like a fish-hawk towards her infant. She caught it, beat her wings, and lifted slowly towards an untouched nest.

  Two nests, burning and exploding, spun towards the ocean. By then several hundreds of males had detached themselves from the ring around the island. They flew after the
gliders, which by now were far down, headed towards a landing on the waves.

  The nests on a level with the island were out of range of his beamer. It was possible the two below might not be. Wolff told Dugarnn what he meant to do and went down a fifty-foot winding staircase to a hatch at its bottom. The nests there had risen close, and he caught both of them with a sweep of the full power of the beamer. They blew up with such violence that he was lifted and almost knocked off the platform. Smoke poured up through the hatch. Then, as it cleared away, he saw the flaming pieces of vegetation falling. The bodies of the children and females plummeted into the sea.

  The male warriors from the nests were trying to get through the bottom hatches. Wolff put the beamer on half-power and cleared the area. Then he ran along the gangplank, stopping at every hatch to fire again. He accounted for at least a hundred attackers. Some had gotten through the defending abutal at the hatches at the far end. It took him a while to kill these, since he had to be careful not to touch the many great bladders. Even though he slew thirty, he could not get them all. The island was too large for him to cover all the bottom area.

  By the time he climbed back up to the hatch, he found that the Nichiddor had launched their mass attack. This end of the island was a swirling, screeching, shouting, screaming mob. There were bodies everywhere.

  The archers and slingers had taken a heavy toll of the first wave and a lighter toll of the second. Then the Nichiddor were upon them, and the battle became a melee. Although the winged men had no weapons other than their wings and feet, these were powerful. With a sweep of a wing, a Nichiddor could knock down an Ilmawir. He could then leap upon his stunned and bruised foe and tear at him with the heavy hooked clawlike toenails. The abutal defended themselves with spears, swords which were flat blades lined with shark's teeth, and knives formed from a bamboolike surface plant.

  Wolff methodically set about to kill all those in the neighborhood of the maindeck. The Lords had made a compact group, all facing outwards and slashing with their swords. Wolff took careful aim and slew the Nichiddor pressing them. A shadow fell on him, and he fell on his back and fired upwards. Two Nichiddor struck the deck on each side of him, the wing of one buffeting him. It covered him like a banner and stank of fish. He crawled out from under just in time to shoot two that had forced Dugarnn back against the wall. Dugarnn's wife lay near him, her spear stuck in a winged man's belly. Her face and breasts were ripped into shreds, and the Nichiddor who had done it was tearing out her belly. He fell backwards, his claws caught in her entrails, as Wolff shot him from behind.

  For the next minute, it was near-death for him. At least two dozen Nichiddor came at him from all sides and from above. He spun like a top, using the beam as a spray, around him and in the air. The corpses, half-severed, smoking, stinking, piled up around him. Then he was over them, out in the open, on the fringes of the eddying battle. He shot everywhere and usually hit his target, though twice an abutal was borne by the thrust of the fight into the beam. This could not be helped; he was lucky that he had not hit more.

  The Ilmawir, despite a fierce resistance, had lost half their numbers. Even with Wolff's help, they were being defeated. The Nichiddor, despite casualties that should have made them retreat, refused to stop. They were intent on extermination of their foe, even if it meant near-extermination for them.

  Wolff cleared the attackers around the Lords again. They were all on their feet and swinging their swords, although covered with blood. Wolff called to them to form around him. While they kept off the winged men, he would shoot over them. He stood upon a pile of Nichiddor, his feet braced on the slippery corpses, and coolly resumed firing. Suddenly, he realized that he was down to his last two power packs. He had hoped to save some for Urizen's stronghold, but there was nothing he could do to conserve them now. If he did not use the beamer, he and all that fought with him would die.

  Vala, standing just in front of him, yelled. He looked upward where she was pointing. A dark object spanned the skies: a black comet. It had appeared while all were intent upon the fight.

  The abutal near them also looked up. They gave a cry of despair and threw down their weapons. Ignoring the winged men, they ran towards the nearest hatches. The Nichiddor, after searching the skies for the cause of the panic, also reacted with terror. They launched themselves into the air to get to the nests or to escape to the protecting underside of the island.

  Wolff did not throw down his beamer, but he was as frenzied as the others in their attempt to get to the closest cover. Dugarnn had told him of the black comets that occasionally visited the space above this planet. He had warned of that which always accompanied the comet.

  As Wolff raced towards a hatch, there were small whistling noises around him. Holes appeared in the foliage of the walls; little curls of smoke rose from the sheathing of the maindeck. A Nichiddor, ten feet up, flapping his fifty-foot wings frantically, screamed. He fell to the deck, his skin pierced in several places, smoke coming from one wing. Another and another winged man dropped, and with them some abutal. The corpses jerked with the impact of the tiny drops.

  Wolff's beamer was knocked out of his hand by the blow of a drop of quicksilver. He stooped and picked it up and resumed his run. For a moment, he could not get into the hatchway because of the Lords jammed before it. They fought each other, cursed, and cried to Los. Some even cried out for their father, Urizen, or their long-dead mother.

  For one wild second, Wolff thought of clearing the way for himself with the beamer. It was exactly what any of them, with the possible exception of Luvah, would have done. To stay out here was to be dead. Every bit of time counted.

  Then whoever was the cause of the pile-up got through, and the others clawed and bit and scratched their way in.

  Wolff went through the hatch in a dive, headfirst. Something touched his pants. His calf burned. There was a splashing noise, and hot mercury clung to the back of his head. He fell past the shallow ladder and hit the floor with his two hands, dropping the beamer before he hit. He absorbed most of the shock with his bent arms and then rolled over. He brought up against Palamabron, who was just starting down the second ladder. Palamabron yelled and pitched forward. Wolff, looking down the well, saw Palamabron on top of a pile of Lords. All were shouting and cursing. None, however, seemed to be hurt badly.

  At another time Wolff would have laughed. Now he was too concerned with scraping the globules of hot mercury from his hair. He examined his leg to make sure that the hit there had only been glancing. Then he went on down the steps. It was best to get as far below as possible. If this were a heavy and steady mercury-drop shower, the entire upper decks could be destroyed. If the big gas-bladders were penetrated, good-bye forever to all.

  VII

  VALA GREETED HIM IN THE TWILIGHT OF A GANGPLANK BY A SPHEROID cell. She was laughing. Her laughter was not hysteria but genuine amusement. He was sure that if there were enough light, he would be able to see her eyes shining with mirth.

  "I'm glad that you find this funny," he said. He was covered with Nichiddor blood, which was rapidly being carried off by his heavy sweating, and he was shaking. "You were always a strange one, Vala. Even as a child, you loved teasing the rest of us and playing cruel jokes upon us. And as a woman, you loved blood and suffering -in others-more than you loved love."

  "So I am a true Lord," she said. "My father's daughter. And, I might add, my brother's sister. You were just like me, dear Jadawin, before you became the namby-pamby human Wolff, the degenerate half-Earthling."

  She came closer, and, lowering her voice, said, "It has been a long time since I have had a man, Jadawin. And you have not touched a woman since you came through the gate. Yet I know that you are like a he-goat, brother, and that you begin to suffer when a day passes without taking a woman to bed. Can you put aside your so-evident loathing of me-which I do not understand-and go with me now? There are a hundred hiding places in this island, dark and warm and private places where no one will disturb us. I a
sk you, though my pride is great."

  She spoke truly. He was an exceedingly strong and vigorous man. Now he felt longing come upon him, a longing that he had put aside every day by constant activity. When night came and he went to bed, he had bent his mind to plots against his father, trying to foresee a thousand contingencies and the best way to dispose of them.

  "First the blood-feast and then the lust-dessert," he said. "It's not I who rouses you but the thrust of the blade and the spurt of blood."

  "Both do," she said. She held out her hand to him. "Come with me."

  He shook his head. "No. And I want to hear no more of this. The subject is forever dead."

  She snarled, "As you will soon be. No one can. . ."

  Vala turned and walked away, and when he next saw her, she was talking earnestly to Palamabron. After a while, the two walked off into the dimness of a corridor.

  He thought for a moment of ordering them back. They were in effect deserting their posts. The danger from the Nichiddor seemed to be over, but if the mercury shower became heavier, the island could be badly crippled or destroyed.
