<h2>VIII</h2>
<p>The great roc's hard-drumming wings set up a constant sound of rushing
air and the distance flowed behind them. There was the rush of wind all
around them, but on the bird's back they were in an area where
everything seemed calm. Only when Hanson looked over toward the ground
was he fully conscious of the speed they were making. From the height,
he could see where the sun had landed. It was sinking slowly into the
earth, lying in a great fused hole. For miles around, smaller drops of
the three-mile-diameter sun had spattered and were etching deeper holes
in the pitted landscape.</p>
<p>Then they began passing over desolate country, scoured by winds, gloomy
from the angry, glaring clouds above. Once, two bodies went hurtling
upwards toward the great gaps in the sky.</p>
<p>"Those risings were from men who were no worshippers of the egg's
hatching," Bork commented. "It's spreading. Something is drawing them up
from all over the planet."</p>
<p>Later, half a square mile of the shell cracked off. The roc squawked
harshly, but it had learned and had been watching above. By a frantic
effort of the great wings, it missed the hurtling chunk. They dropped a
few thousand feet in the winds that followed the piece of sky, but their
altitude was still safe.</p>
<p>Then they passed over a town, flying low. The sights below were out of a
ghoul's bacchanalia. As the roc swept over, the people stopped their
frenzied pursuit <span class="pagenum">[Pg 91]</span> of sensation and ran for weapons. A cloud of arrows
hissed upwards, all fortunately too late.</p>
<p>"They blame all their troubles on the magicians," Bork explained.
"They've been shooting at everything that flies. Not a happy time to
associate with the Satheri, is it?"</p>
<p>Nema drew further back from him. "We're not all cowards like you! Only
rats desert a sinking ship."</p>
<p>"Nobody thought it was sinking when I deserted," Bork reminded her.
"Anyhow, if you'd been using your eyes and seen the way we are
traveling, you'd know I've rejoined the crew. I've made up with the
Sather Karf—and at a time like this, our great grandfather was glad to
have me back!"</p>
<p>Nema rushed toward him in delight, but Hanson wasn't convinced. "Why?"
he asked.</p>
<p>Bork sobered. "One of the corpses that fell back from the risings added
a word to what the others had said. No, I'll bear the weight of it
myself, and not burden you with it. But I'm convinced now that his egg
should not hatch. I had doubts before, unlike our friend Malok, who also
heard the words but is doubly the fanatic now. Perhaps the hatching
cannot be stopped—but I've decided that I am a man and must fight like
one against the fates. So, though I still oppose much that the Satheri
have done, I've gone back to them. We'll be at the camp of the Sather
Karf shortly."</p>
<p>That sewed everything up neatly, Hanson thought. Before, he had been
torn between two alternatives. Now there was only one and he had no
choice; he could never trust the Sons of the Egg with Bork turned
against them. He stared up at the sky, realizing that more than half of
it had already fallen. The rest seemed too weak to last much longer. It
probably didn't make <span class="pagenum">[Pg 92]</span> much difference what he did now or who had him;
time was running out for this world.</p>
<p>The light was dimmer by the time they reached the great capital city—or
what was left of it. They had left the sun pyre far to the south. The
air was growing cold already.</p>
<p>The roc flew low over the city. The few people on the streets looked up
and made threatening gestures, but there was no flight of arrows from
the ground. Probably the men below had lost even the strength to hate.
It was hard to see, since there was no electric lighting system now. But
it seemed to Hanson that only the oldest and ugliest buildings were
still standing. Honest stone and metal could survive, but the work of
magic was no longer safe.</p>
<p>One of the remaining buildings seemed to be a hospital, and the empty
space in front of it was crammed with people. Most of them seemed to be
dead or unconscious. Squat mandrakes were carrying off bodies toward a
great fire that was burning in another square. Plague and pestilence had
apparently gotten out of hand.</p>
<p>They flew on, beyond the city toward the construction camp that had been
Hanson's headquarters. The roc was beginning to drop into a long landing
glide, and details below were easier to see. Along the beach beyond the
city, a crowd had collected. They had a fire going and were preparing to
cook one of the mermaids. A fight was already going on over the prey.
Food must have been exhausted days before.</p>
<p>The camp was a mess when they reached it. One section had been ripped
down by the lash of wind from a huge piece of the sky, which now lay
among the ruins with a few stars glowing inside it. There was a <span class="pagenum">[Pg 93]</span>
brighter glow beyond. Apparently one blob of material from the sun had
been tossed all the way here and had landed against a huge rock to
spatter into fragments. The heat from those fragments cut through the
chill in the air, and the glow furnished light for most of the camp.</p>
<p>The tents had been burned, but there was a new building where the main
tent had been. This was obviously a hasty construction job, thrown
together of rocks and tree trunks, without the use of magic. It was more
of an enormous lean-to than a true building, but it was the best
protection now available. Hanson could see Sather Karf and Sersa Garm
waiting outside, together with less than a hundred other warlocks.</p>
<p>The mandrakes prodded Hanson down from the roc and toward the new
building, then left at a wave of the Sather Karf's hand. The old man
stared at Hanson intently, but his expression was unreadable. He seemed
to have aged a thousand years. Finally he lifted his hand in faint
greeting, sighed and dropped slowly to a seat. His face seemed to
collapse, with the iron running out of it. He looked like a beaten, sick
old man. His voice was toneless. "Fix the sky, Dave Hanson!"</p>
<p>There were angry murmurs from other warlocks in the background, but
Sather Karf shook his head slowly, still facing Hanson. "No—what good
to threaten dire punishments or to torture you when another day or week
will see the end of everything? What good to demand your reasons for
desertion when time is so short? Fix the sky and claim what reward you
will afterwards. We have few powers now that the basis of astrology is
ruined. But repair our sky and we can reward you beyond your dreams. We
can find ways to return you to your own world intact. You have near
immortality <span class="pagenum">[Pg 94]</span> now. We can fill that entire lifetime with pleasures. We'll
give you jewels to buy an empire. Or if it is vengeance against whatever
you feel we are, you shall know my secret name and the name of everyone
here. Do with us then what you like. <i>But fix the sky!</i>"</p>
<p>It shook Hanson. He had been prepared to face fury, or to try lying his
way out if there was a chance with some story of having needed to study
Menes's methods. Or of being lost. But he had no defense prepared
against such an appeal.</p>
<p>It was utterly mad. He could do nothing, and their demands were
impossible. But before the picture of the world dying and the decay of
the old Sather's pride, even Hanson's own probable death with the dying
world seemed unimportant. He might at least give them something to hope
for while the end came.</p>
<p>"Maybe," he said slowly. "Maybe, if all of the men you brought here to
work on the problem were to pool their knowledge, we might still find
the answer. How long will it take to get them here for a council?"</p>
<p>Ser Perth appeared from the group. Hanson had thought the man dead in
the ruins of the pyramid, but somehow he had survived. The fat was going
from his face, and his mustache was untrimmed, but he was uninjured. He
shook his head sadly. "Most have disappeared with their projects. Two
escaped us. Menes is dead. Cagliostro tricked us successfully. You are
all we have left. And we can't even supply labor beyond those you see
here. The people no longer obey us, since we have no food to give them."</p>
<p>"You're the only hope," Bork agreed. "They've saved what they could of
the tools from the camp and what magical instruments are still useful.
They've held on only for your return." <span class="pagenum">[Pg 95]</span></p>
<p>Hanson stared at them and around at the collection of bric-a-brac and
machinery they had assembled for him. He opened his mouth, and his
laughter was a mockery of their hopes and of himself.</p>
<p>"Dave Hanson, world saver! You got the right name but the wrong man,
Sather Karf," he said bitterly. He'd been a pretender long enough, and
what punitive action they took now didn't seem to matter. "You wanted my
uncle, David Arnold Hanson. But because his friends called him Dave and
cut that name on his monument, and because I was christened by the name
you called, you got me instead. He'd have been helpless here, probably,
but with me you have no chance. I couldn't even build a doghouse. I
wasn't even a construction engineer. Just a computer operator and
repairman."</p>
<p>He regretted ruining their hopes, almost as he said it. But he could see
no change on the old Sather's face. It seemed to stiffen slightly and
become more thoughtful, but there was no disappointment.</p>
<p>"My grandson Bork told me all that," he said. "Yet your name was on the
monument, and we drew you back by its use. Our ancient prophecy declared
that we should find omnipotence carved on stone in a pool of water, as
we found your name. Therefore, by the laws of rational magic, it is
<i>you</i> to whom nothing is impossible. We may have mistaken the direction
of your talent, but nonetheless it is you who must fix the sky. What
form of wonder is a computer?"</p>
<p>Dave shook his head at the old man's monomania. "Just a tool. It's a
little hard to explain, and it couldn't help."</p>
<p>"Humor my curiosity, then. What is a computer, Dave Hanson?"</p>
<p>Nema's hand rested on Hanson's arm pleadingly, and <span class="pagenum">[Pg 96]</span> he shrugged. He
groped about for some answer that could be phrased in their language,
letting his mind flicker from the modern electronic gadgets back to the
old-time tide predicter.</p>
<p>"An analogue computer is a machine that ... that sets up conditions
mathematically similar to the conditions in some problem and then lets
all the operations proceed while it draws a graph—a prediction—of how
the real conditions would turn out. If the tides change with the
position of some heavenly body, then we can build cams that have shapes
like the effect of the moon's orbit, and gear them together in the right
order. If there are many factors, we have a cam for each factor, shaped
like the periodic rise and fall of that factor. They're all geared to
let the various factors operate at the proper relative rate. With such a
machine, we can run off a graph of the tides for years ahead. Oh,
hell—it's a lot more complicated than that, but it takes the basic
facts and draws a picture of the results. We use electronic ones now,
but the results are the same."</p>
<p>"I understand," Sather Karf said. Dave doubted it, but he was happy to
be saved from struggling with a more detailed explanation. And maybe the
old man did understand some of it. He was no fool in his own subject,
certainly. Sather Karf pondered for a moment, and then nodded with
apparent satisfaction. "Your world was more advanced in understanding
than I had thought. This computer is a fine scientific instrument,
obeying natural law well. We have applied the same methods, though less
elaborately. But the basic magical principle of similarity is the
foundation of true science."</p>
<p>Dave started to protest, and then stopped, frowning. In a way, what the
other had said was true. Maybe <span class="pagenum">[Pg 97]</span> there was some relation between science
and magic, after all; there might even be a meeting ground between the
laws of the two worlds he knew. Computers set up similar conditions,
with the idea that the results would apply to the original. Magic used
some symbolic part of a thing in manipulations that were to be effective
for the real thing. The essential difference was that science was
predictive and magic was effective—though the end results were often
the same. On Dave's world, the cardinal rule of logic was that the
symbol was not the thing—and work done on symbols had to be translated
by hard work into reality. Maybe things were really more logical here
where the symbol was the thing, and all the steps in between thought and
result were saved.</p>
<p>"So we are all at fault," Sather Karf said finally. "We should have
studied you more deeply and you should have been more honest with us.
Then we could have obtained a computer for you and you could have
simulated our sky as it should be within your computer and forced it to
be repaired long ago. But there's no time for regrets now. We cannot
help you, so you must help yourself. Build a computer, Dave Hanson!"</p>
<p>"It's impossible."</p>
<p>Sudden rage burned on the old man's face, and he came to his feet. His
arm jerked back and snapped forward. Nothing happened. He grimaced at
the ruined sky. "Dave Hanson," he cried sharply, "by the unfailing power
of your name which is all of you, I hold you in my mind and your throat
is in my hand—"</p>
<p>The old hands squeezed suddenly, and Hanson felt a vise clamp down
around his throat. He tried to break free, but there was no escape. The
old man mumbled, and the vise was gone, but something clawed at <span class="pagenum">[Pg 98]</span>Hanson's
liver. Something else rasped across his sciatic nerve. His kidneys
seemed to be wrenched out of him.</p>
<p>"You will build a computer," Sather Karf ordered. "And you <i>will</i> save
our world!"</p>
<p>Hanson staggered from the shock of the pain, but he was no longer unused
to agony. He had spent too many hours under the baking of the sun, the
agony of the snetha-knife and the lash of an overseer's whip. The agony
could not be stopped, but he'd learned it could be endured. His
fantastic body could heal itself against whatever they did to him, and
his mind refused to accept the torture supinely. He took a step toward
Sather Karf, and another. His hands came up as he moved forward.</p>
<p>Bork laughed suddenly. "Let up, Sather Karf, or you'll regret it. By the
laws, you're dealing with a <i>man</i> this time. Let up, or I'll free him to
meet you fairly."</p>
<p>The old man's eyes blazed hotly. Then he sighed and relaxed. The
clutching hands and the pain were gone from Hanson as the Sather Karf
slumped back wearily to his seat.</p>
<p>"Fix our sky," the old man said woodenly.</p>
<p>Hanson staggered back, panting from his efforts. But he nodded. "All
right," he agreed. "Like Bork, I think a man has to fight against his
fate, no matter how little chance he has. I'll do what I can. I'll build
the damned computer. But when I'm finished, I'll wait for <i>your</i> true
name!"</p>
<p>Suddenly Sather Karf laughed. "Well said, Dave Hanson. You'll have my
name when the time comes. And whatever else you desire. Also what poor
help we can give you now. Ser Perth, bring food for Dave Hanson!"</p>
<p>Ser Perth shook his head sadly. "There is none. None at all. We hoped
that the remaining planets would find a favorable conjunction, but—" <span class="pagenum">[Pg 99]</span></p>
<p>Dave Hanson studied his helpers with more bitterness. "Oh, hell!" he
said at last. He snapped his fingers. "Abracadabra!"</p>
<p>His skill must be improving, since he got exactly what he had wished
for. A full side of beef materialized against his palm, almost breaking
his arm before he could snap it out of the way. The others swarmed
hungrily toward it. At their expressions of wonder, Hanson felt more
confidence returning to him. He concentrated and went through the little
ritual again. This time loaves of bread rained down—fresh bread, and
even of the brand he had wished for. Maybe he was becoming a magician
himself, with a new magic that might still accomplish something.</p>
<p>Sather Karf smiled approvingly. "The theory of resonance, I see.
Unreliable generally. More of an art than a science. But you show
promise of remarkable natural ability to apply it."</p>
<p>"You know about it?" Dave had assumed that it was completely outside
their experience and procedures.</p>
<p>"We <i>knew</i> it. But when more advanced techniques took over, most of us
forgot it. The syllables resonate in a sound pattern with your world, to
which you also still resonate. It won't work for you with anything from
this world, nor will anything work thus for us from yours. We had
different syllables, of course, for use here." Sather Karf considered
it. "But if you can control it and bring in one of your computers or the
parts for one—"</p>
<p>Sixteen tries later, Dave was cursing as he stared at a pile of useless
items. He'd gotten transistors at first. Then he lost control with too
much tension or fatigue and began getting a bunch of assorted junk, such
as old 201-A tubes, a transit, a crystal vase and resistors. But the
chief trouble was that he couldn't secure working batteries.<span class="pagenum">[Pg 100]</span> He had
managed a few, but all were dead.</p>
<p>"Like the soul, electrical charges will not transfer," Sather Karf
agreed sadly. "I should have told you that."</p>
<p>There was no electricity here with which to power anything, and their
spells could not be made to work now. Even if he could build a computer
out of what was obtainable, there would be no way to power it.</p>
<p>Overhead, the sky shattered with a roar, and another piece fell, tearing
downwards toward the city. Sersa Garm stared upwards in horror.</p>
<p>"Mars!" he croaked. "Mars has fallen. Now can there be no conjunction
ever!"</p>
<p>He tautened and his body rose slowly from the ground. A scream ripped
from his lips and faded away as he began rushing upwards with increasing
speed. He passed but of their sight, straight toward the new hole in the
sky.<span class="pagenum">[Pg 101]</span></p>
