"A reasonably intelligent man should be able — " Dave began.
Ser Perth cut his words off with a sharp laugh. "Maybe a man. But who said you were a man, Dave Hanson? Can't you even understand that? You're only half human. The other half is mandrake — a plant that is related to humanity through shapes and signs by magic. We make simulacra out of mandrakes — like the manicurist in the barber shop. And sometimes we use a mandrake root to capture the essence of a real man, in which case he's a mandrake-man, like you. Human? No. But a very good imitation, I must admit."
Dave turned from Ser Perth toward Nema, but her head was bent over the cords she was weaving, and she avoided his eyes. He remembered now that she'd called him a mandrake-man before, in a tone of pity. He looked down at his body, sick in his mind. Vague bits of fairy tales came back to him, suggesting horrible things about mandrake creatures — zombie-like things, only outwardly human.
Sather Karf seemed amused as he looked at Ser Perth. Then the old man dropped his eyes toward Dave, and there was a brief look of pity in them. "No matter, Dave Hanson," he said. "You were human, and by the power of your true name, you are still the same Dave Hanson. We have given you life as precious as your other life. Pay us for that with your service, and that new life will be truly precious. We need your services."
"What do you want?" Dave asked. He couldn't fully believe what he'd heard, but there had been too many strange things to let him disbelieve, either. If they had made him a mandrake-man, then by what little he could remember and guess, they could make him obey them.
"Look out the window — at the sky," Sather Karf ordered.
Dave looked. The sunset colors were still vivid. He stepped forward and peered through the crystalline glass. Before him was a city, bathed in orange and red, towering like the skyline of a dozen cities he had seen — and yet; not like any. The buildings were huge and many-windowed. But some were straight and tall, some were squat and fairy-colored and others blossomed from thin stalks into impossibly bulbous, minareted domes, like long-stemmed tulips reproduced in stone. Haroun-al-Rashid might have accepted the city, but Mayor Wagner could never have believed in it.
"Look at the sky," the old man suggested again, and there was no mockery in his voice now.
Dave looked up obediently.
The sunset colors were not sunset. The sun was bright and blinding overhead, surrounded by reddish clouds, glaring down on the fairy city. The sky was — blotchy. It was daylight, but through the clouds bright stars were shining. A corner of the horizon was winter blue; a whole sweep of it was dead, featureless black. It was a nightmare sky, an impossible sky. Dave's eyes bulged as he looked at it.
He turned back to Sather Karf. "What — what's the matter with it?"
"What indeed?" There was bitterness and fear in the old man's voice. In the corner of the room, Nema looked up for a moment, and there was fear and worry in her eyes before she looked back to her weaving of endless knots. Sather Karf sighed in weariness. "If I knew what was happening to the sky, would I be dredging the muck of Duality for the likes of you, Dave Hanson!"
He stood up, wearily but with a certain ease and grace that belied his age, looking down at Dave. There was stern command in his words, but a hint of pleading in his expression.
"The sky's falling, Dave Hanson. Your task is to put it together again. See that you do not fail us!"
He waved dismissal and Ser Perth led Dave and Nema out.

The corridor down which they moved this time was one that might have been familiar even in Dave's Chicago. There was the sound of typewriters from behind the doors, and the floor was covered with composition tile, instead of the too-lush carpets. He began to relax a little until he came to two attendants busily waxing the floor. One held the other by the ankles and pushed the creature's hairy face back and forth, while its hands spread the wax ahead of it. The results were excellent, but Dave found it hard to appreciate.
Ser Perth shrugged slightly. "They're only mandrakes," he explained. He threw open the door of one of the offices and led them through an outer room toward an inner chamber, equipped with comfortable chairs and a desk. "Sit down, Dave Hanson. I'll fill you in on anything you need to know before you're assigned. Now — the Sather Karf told you what you were to do, of course, but — "
"Wait a minute," Dave suggested. "I don't remember being told any such thing."
Ser Perth looked at Nema, who nodded. "He distinctly said you were to repair the sky. I've got it down in my notes if you want to see them." She extended the woven cords.
"Never mind," Ser Perth said. He twiddled with his mustache. "I'll recap a little. Dave Hanson, as you have seen, the sky is falling and must be repaired. You are our best hope. We know that from a prophecy, and it is confirmed by the fact that the fanatics of the Egg have tried several times to kill you. They failed, though one effort was close enough, but their attempts would not have been made at all if they had not been convinced through their arts that you can succeed with the sky."
Dave shook his head. "It's nice to know you trust me!"
"Knowing that you can succeed," the other went on smoothly, "we know that you will. It is my unpleasant duty to point out to you the things that will happen if you fail. I say nothing of the fact that you owe us your life; that may be a small enough gift, and one quickly withdrawn. I say only that you have no escape from us. We have your name, and the true symbol is the thing, as you should know. We also have cuttings from your hair and your beard; we have the parings of your nails, five cubic centimeters of your spinal fluid and a scraping from your liver. We have your body through those, nor can you take it out of our reach. Your name gives us your soul." He looked at Hanson piercingly. "Shall I tell you what it would be like for your soul to live in the muck of a swamp in a mandrake root?"
Dave shook his head. "I guess not. I — look, Ser Perth. I don't know what you're talking about. How can I go along with you when I'm in the dark? Start at the beginning, will you? I was killed; all right, if you say I was, I was. You brought me to life again with a mandrake root and spells; you can do anything you want with me. I admit it; right now, I'll admit anything you want me to, because you know what's going on and I don't. But what's all this business of the sky falling? If it is and can be falling, what's the difference? If there is a difference, why should I be able to do anything about it?"
"Ignorance!" Ser Perth murmured to himself. He sighed heavily. "Always ignorance. Well, then, listen." He sat down on the corner of the desk and took out a cigarette. At least it looked like a cigarette. He snapped his fingers and lighted it from a little flame that sprang up, blowing clouds of bright green smoke from his mouth. The smoke hung lazily, drifting into vague patterns and then began to coalesce into a green houri without costume. He swatted at it negligently.
"Dratted sylphs. There's no controlling the elementals properly any more." He didn't seem too displeased, however, as he watched the thing dance off. Then he sobered.
"In your world, Dave Hanson, you were versed in the engineering arts — you more than most. That you should be so ignorant, though you were considered brilliant is a sad commentary on your world. But no matter. Perhaps you can at least learn quickly still. Even you must have had some idea of the composition of the sky?"
Dave frowned as he tried to answer. "Well, I suppose the atmosphere is oxygen and nitrogen, mostly; then there's the ionosphere and the ozone layer. As I remember, the color of the sky is due to the scattering of light — light rays being diffracted in the air."
"Beyond the air," Ser Perth said impatiently. "The sky itself!"
"Oh — space. We were just getting out there
