Chapter 1
The tree named Yggdrasil plunged toward the heart of the galaxy at very nearly the speed of light, safe
within a cone of shadow from a sleet of radiation that otherwise would have charred it to ash in
microseconds.
It still clutched the remains of a comet in its roots, so water was not yet a problem. But light and gravity
were strangely wrong, interfering with its tropisms.
Yggdrasil was a very confused tree.
Ahead, always, was a funnel of dancing sparks. Behind was a terribly bright light. Yggdrasil's senses told
it that it was in the terrifying grip of a one-g gravitational field that was tugging it toward that unnatural
sun. It had been trying for twenty years to escape. But when it tried to turn the reflective surfaces of its
leaves toward the perpendicular, something always frustrated it.
Yet, wonder of wonders, Yggdrasil never fell. An equal and opposite force applied to a small region of
its central trunk prevented that. Yggdrasil knew in its vegetable fashion that a girdle of foreign substance
encircled its waist, but its senses were not adequate to tell it about the tether and the gargantuan
turnbuckle that anchored the girdle.
A strange thing had happened to the stars as well. They swarmed around the tree in rainbow hoops of

color—violet, then blues, greens, and yellows ahead; orange and progressively darker reds behind. Both
ahead and behind, blind disks had blossomed as the stars marched in both directions through the
spectrum and disappeared. The rearward blind spot was larger. Over the years it had kept. expanding,
compressing the rainbow hoops and pushing them forward until now they circled the coruscating funnel of
sparks like concentric halos.
Scores of times Yggdrasil had tried to pick a yellow target star, only to have it change colors and vanish
from the universe.
Only the odd pursuing sun had not dopplered through the spectrum. It remained fixed in color and
distance, seeming to grow ever brighter against the expanding dark region behind it.
Fretting, Yggdrasil tried to concentrate on growing one of its branches. Its crown—since it had been
prevented from spinning—was no longer perfectly symmetrical, and this was a branch that needed to
catch up. Fortunately, the direction of the tug of gravity was always a guide. Growth, Yggdrasil knew in
its simple wisdom, was supposed to be perpendicular.
There was commensal life within the cavities of the errant branch, but it was too insignificant to be
noticed. Yggdrasil ignored it. The only verities were light, gravitation, and water.
"I think Yggdrasil needs a tranquilizer again," the tree systems officer said. "It's starting to show signs of
trauma."
Bram set down the carton of housewares he had been packing and turned to face her. "Are you sure?"
he said.
"I'm afraid so, Captain," she said. "The monitors indicate enzymatic reactions in the heartwood, and
gallic acid's showing in the contents of the parenchymal cells."
Mim, coming through into the observation veranda with another armload of empty cartons, heard the
exchange, "Oh, no!" she exclaimed. "Right in the middle of moving week!"
Bram shot her an affectionate glance. Mim was well past middle age now—the mirror showed fewer
gray hairs every day—but her handsome face still preserved some of the lines it had acquired during their
four decades together. To Bram's way of thinking, the lines gave her a strength of character and a beauty
that he had come to love; it was hard to imagine Mim without them, but youthing was inevitable, and he
supposed he would have to get used to it.
"Have you tried readjusting the auxin balance?" Bram said.
The tree systems officer looked worried. "We're close to the limit on that, Captain," she said. "Any more
might be dangerous. Yggdrasilknows it's edge-on to something that looks like a sun to it and that half of
its crown's in shadow. We can only deceive it so far, then the separate deceptions start to contradict
each other. Too many auxins on the lit side, and we could have a very sick tree."
She waited diffidently for his response. The tree systems officer was a grandchild of Jao and Ang, and
like many of her contemporaries she tended to treat Bram like a monument. She had not even been born
yet when he had begun the immortality project. But Bram knew that she was a first-rate botanist, and he
trusted her judgment.
Bram sighed. "All right. I suppose we'd better keep Yggdrasil tranquilized at least through moving week.

We can't afford a delay. The branch we're living in is getting a bit bosky. And we're already ten degrees
out of plumb." His eyes crinkled humorously. "Besides, we'd have a mutiny on our hands if we held up
Bobbing Day."
"Very good, Captain," she said without cracking a smile. She turned smartly on her heel and left.
Bram watched her go. She had made him feel old and hoary. There was no reason for it, he told himself.
His apparent age was down to somewhere in the midforties by now. But his body still carried the
memory of being much older, and it showed sometimes in the way he moved and in the habit of
protective postures. That, too, would pass with time, Bram supposed.
"The new ones are soearnest ," Mim said, reading his thoughts.
"I just wish they wouldn't call me 'Captain' all the time."
She laughed. "But youare captain this year. And you've been elected seven times. That's more than
anybody."
"It's only ancestor worship," he said. "Exaggerated respect for all the old father figures. And mother
figures," he added hastily.
"Then why was Jao elected only once?" she teased him.
"And never again—I know, it was a disaster! Jao's the first one to tell you that himself."
"Jao never wanted to be captain in the first place. I sometimes suspect he sabotaged his first term on
purpose so they'd never ask him again. But pity poor Smeth. He keeps campaigning, and he hasn't been
elected once yet."
"Save your pity. Give him time. He has the next five hundred years to round up the votes. I'll bet that by
the time we get to the Milky Way, he'll hold the record for being elected the most often. Because by then
he'll be the only one whowants the job."
She giggled appreciatively, though she never would have hurt Smeth's feelings by doing it in his presence.
"And when you remember how he kept telling everybody that he had no intention of coming with
us—thathe wouldn't trusthis life to an overgrown plant and a jerry-built ramscoop drive!"
Smeth had been a surprise to both of them. Bram had been sure that Smeth would stay behind. By the
time the probe project had reached fruition, Smeth had accreted a huge department, with more than a
hundred humans beneath him. He had attached himself like glue to the Nar organizational superstructure,
and the Nar, thinking they were stepping softly on human sensibilities, funneled everything through him,
snowballing his authority. He had nothing to gain by deserting the new egalitarian society that human
immortality had brought about. With eternity ahead of him, he had nowhere to go but up.
But when the day had come to board Yggdrasil or be left behind, Smeth had showed up at the
shuttleport with a small bag of personal belongings and a string of six biosynthetic walkers, led by a Nar
porter bearing his library, instruments, and accumulated records.
"I guess he decided that it was better to be a big floater in a small pool," Bram said.

"Or maybe he simply couldn'tbear the idea of all of us leaving without him."
Bram nodded. "After he saw the stampede that developed."
Smeth had not been the only surprise. More than five thousand people had elected to go along on the
genesis quest—almost a third of the human race. The project had tapped a deep longing. The Nar had
not underestimated the strength of the buried feelings unearthed in their pets. About ten years into the
project, they had begun a program to gather all candidates from the farther worlds, and it had taken
another twenty years to bring them all in. Those who had waited too long or who had changed their
minds at the last minute had been out of luck.
"Well, I'm glad he decided to come along. It wouldn't be the same without him."
"Yes. I have to admit he's improving."
Mim fell silent. Bram knew she was thinking about Olan Byr. Immortality had come too late for Olan.
The project had been a long, hard one, even with the blueprints of Original Man to work from and the full
cooperation of the Nar. There had been times when Bram had thought that he himself would grow too
old to benefit from it.
Mim had had fifty years to get over her grief for Olan. Forty of them had been spent with Bram. By the
time they had drifted together, she had been too old for children. But her fertility had returned during the
last few years, and lately she had been thinking about having a baby after she grew another ten or fifteen
years younger. But only if tree demographics permitted, she was always quick to add whenever the
subject came up. Yggdrasil could easily support another twenty thousand humans—in fact, about five
hundred babies had been born already. But everyone was aware that a long trip lay ahead of them.
Bram reached for her hand, and they exchanged smiles. "Go ahead," she said. "I'll finish the packing.
You'd better see to Yggdrasil's tranquilizer. If the drinks get sloshed over the rims of all the glasses on
All-Level Eve, Marg will have a fit."
"Life would certainly be simpler," he said, "if we didn't have to rotate our environment thirty degrees
every year to keep Yggdrasil from getting lopsided."
She squeezed his hand. "But it wouldn't be half as much fun," she said.
It was an hour's ride to the trunk even by slingshot, but Bram always enjoyed the view. There was no
real reason to make the trip—the tree systems staff was fully competent and, in fact, knew more about
the operation of the tree than he did—but the approaching tree-turning maneuver made a good excuse
for the excursion.
He reeled in an empty travelpod, eased it through the lips of the gasket, and clambered inside. The
absurdly simple arrangement made the expense of air locks for the external travel system unnecessary;
otherwise, twelve air locks would have had been installed. The main rack of cables, like an abacus one
hundred fifty miles long, was anchored at a new terminus every year, thirty degrees farther along the rim
of the tree's crown, leaving a couple of permanent cables behind for standby access to the abandoned
branch.
So far, the only major internal fast-transit system was limited to one branch—the one the human
population would be living in during the half millennium when they were coasting between galaxies, and
Yggdrasil could be allowed to have its normal one-g spin again. But that was one hundred and twenty
Generated by ABC Amber LIT Converter, http://www.processtext.com/abclit.html
degrees away at the moment, its halls and compartments standing on their heads, its pools drained, and
everything important either moved or lashed down.
Bram took a moment to check out the pod's systems. Nothing could go wrong, of course; there was an
FM rescue beeper in every pod that would quickly summon help in an emergency. But for someone
serving as year-captain, it would be embarrassing to be stranded halfway along the guide rope and have
someone come to fetch him.
He made sure the air bladder carried enough reserve for the hour's trip and that the emergency bottle
under the seat was full. He squinted through the hyaloid membrane of the docking chamber's blister and
sighted upward along the elastic cable. The several hundred feet of it that he could see before it came
invisible against the distant trunk were reassuringly opaque, indicating that the molecular structure was in
a mostly crystalline state.
He grinned as he prepared to change that. He got the little bottle of boron trifluoride out of the
dashboard and applied a few drops with an eyedropper to the elastomer line, just forward of the bowline
knot that hitched it to an interior stanchion.
The pod gave a shudder as the line began to contract. Bram could see the triggered section turning
transparent as its molecular structure became amorphous. The transparent portion shot outward, erasing
the cable from sight. A few minutes later, when enough miles of cable had been triggered to overcome
the one-g force stretching the line, the pod picked up speed, burst through the gasket, and flew up the
guideline toward Yggdrasil's distant trunk.
Bram held on. He was glad the process wasn't instantaneous. He wouldn't have fancied a snapped neck.
There was a lot of energy stored in a hundred and fifty miles of superelastic line. As it was, the pod
would accelerate at a comfortable rate, never passing two g's at its zenith, then slow to a bounce as the
trailing cable began to tighten.
The organic elastomer, with a stretch ratio of over a thousand to one, was a by-product of the exodus
research program and, by departure time, had already found wide industrial application on the Father
World. The raw materials came from Yggdrasil itself—derived from the adaptive mechanism by which a
tree with a three-hundred-mile diameter synchronized the turgor movements of its leaves.
Bram gazed unabashedly through the transparent skin of his rubbery container and admired the outside
view.
Straight up, of course, was a silhouette of Yggdrasil's trunk seen against the swirling blizzard of sparks
created by the ramscoop field some hundreds of miles in front of the tree.
The silhouette was a short, thick bar, lacking detail. The shower of light was pretty—even jolly—but
Bram knew that its beauty was a lie. It was the emblem of instant death—the visible by-product of the
inferno of radiation pouring into the probe's magnetic funnel. At more than ninety-nine percent of the
speed of light, here in the thick of the galaxy where the H-II clouds were dense, some two hundred
trillion hydrogen atoms slammed into every square inch of the electromagnetic shield every second. Even
allowing for a gamma factor of twenty thousand—the last figure Jao had given him—that worked out to
twenty billion high-energy collisions per second within the ship's relativistic time frame.
If that shield were to fail for even a fraction of a second at this velocity, five thousand humans would die
before their nervous systems were able to register the fact. And Yggdrasil would turn to stardust.
Generated by ABC Amber LIT Converter, http://www.processtext.com/abclit.html
Bram shuddered. As frightening as that umbrella of sparks was, at least it hid the nothingness
beyond—the blind spot where the crowded wavelengths of light pushed past the visible spectrum and
wiped the stars from the universe. The blind spot behind, eerily framing the artificial sun of the fusion
stage of the drive, was bad enough.
He let his eyes follow the long, mirror-bright shaft downward to where the fusion flames burned. The
waste light had enough red in it for Yggdrasil to carry on photosynthesis, enough ultraviolet for human
sunbathers to tan themselves by behind the lenticels of the recreation areas.
The long shaft threaded a dangerous course between Yggdrasil's twin domes. At its closest point it
passed within forty miles of the trunk, and Yggdrasil itself had provided extra protection there—growing
a shield of adventitious leaves with their silvery reflective sides facing out. The star tree could handle
anything up through x-rays.
The material part of the shaft was its least important aspect. In fact, its tremendous length could not have
held up under even moderate lateral stress. It was there to provide support for the winding coils that
deflected the roaring streams of ionized hydrogen in their constricted path from the collection area
forward to the ignition cage aft.
For a moment Bram tried to imagine what the whole crazy travel arrangement would look like to a
hypothetical observer outside the craft—provided that the observer could see by undopplered light. Or,
more to the point, provided that the observer was in the same relativistic frame, matching the spacecraft's
course in velocity and direction. Otherwise, the collection of shapes on their long skewer would be
foreshortened by a factor of twenty thousand, turning them into a stack of paper-thin disks pierced by a
thumbtack.
He decided it would look like a post horn straddled by a leafy dumbbell.
Bram had seen a post horn once, at one of Olan Byr's memorial concerts. The ancient instruments, from
lyres to sousaphones, had been part of Olan's legacy. He had been tireless in commissioning
reproductions from hints in man's digitally transmitted art masterpieces, dictionary sketches, and clues in
the musical notation itself. The post horn was based on one played by an angel in an Annunciation. It was
a long, straight tube of brass, tall as the man who played it, with a flaring bell at one end and the smaller
flare of a mouthpiece at the other.
Bram closed his eyes for a moment and savored the eccentric image.
The post horn that dragged Yggdrasil by the collar was twelve hundred miles long, with its slender tube
aligned along g forces to keep it straight. The bell was an insubstantial net of superfilament, several
hundred miles in diameter, that kept its shape by virtue of an independent spin at its rim. Around the bell
was a multicolored cascade of sparks, like trumpet notes made visible. A miniature sun burned blindingly
in a magnetic cage at the mouthpiece, like a divine breath. And from the flared mouthpiece issued a thin
pencil of inspired light as the hadronic photons, their work done, decayed and wreaked havoc with
whatever interstellar debris was still left behind in the wake of the probe's sweep.
Pleased with the image, he conjured up the other component of the queer hybrid vehicle.
Yggdrasil would make a compressed sort of dumbbell, he decided, with a short, thick handle and rather
flattened hemispheres. More like a pair of fat wheels lying athwart the long axis of the probe. One
hemisphere was silver with a green rim facing the fusion fire. The other was brown, laced through with the
crystal sparkle of cometary ice and showing an arc of green where Yggdrasil's root system had decided
Generated by ABC Amber LIT Converter, http://www.processtext.com/abclit.html
to help out with the photosynthesis.
The looming reality of a wall of foliage rushing past him only a few miles away dissipated the image, and
Bram turned his eyes to the view he loved best.
Between the rushing walls of Yggdrasil's twin hemispheres, a spectacular slice of sky was visible. A
rainbow of stars made a dazzling arch across the void. Optical effects had crowded the bands of color so
close together that the effect was like strands of matched jewels, jumbled together in overlapping
profusion.
It was so beautiful that it hurt.
Bram studied the ribbon of stars. Was it narrower than the last time he had looked? It was hard to tell.
But the yellow band seemed to have moved a degree forward, and the dull, ominous blanket of reds that
faded into the blind spot seemed to have been dragged along by the rainbow hem.
A star whizzed by, changing from purple to blue to green, then to yellow, orange, and red before it was
swallowed by the blind spot.
The star must have been very close—only a few light-days away. At the present gamma, Yggdrasil
swept across a light-year in about thirty minutes. That was fast enough to make the nearer stars move at
a crawl, changing their colors as they lined up against the background rainbow.
A second violet star popped out of nothingness, riffled through the spectrum, and vanished to the rear.
The first star's companion! Yggdrasil was skirting a double star system.
Bram tried not to worry. Even here in the depths of the galaxy the stars were light-months apart. A
collision would be most improbable, Jao had assured him. Even if Smeth's instruments were to show
Yggdrasil heading straight toward a star emerging from a dust cloud, there would be minutes—perhaps
hours—to change course. A lateral nudge of less than half a degree, projected over a minute or two of
travel, would always give them margin to spare.
He drank in the glittering, spectacle again, wondering how much longer he would be able to enjoy it. As
Yggdrasil's speed increased, eventually the stellar rainbow would shrink into a thin gold rim framing the
forward blind spot, and the vortex of hydrogen influx would make it invisible from any part of the tree.
He had tried to get a time estimate from Jao, but Jao had been vague. They were slicing the remainder of
the speed of light so thin at this point, Jao said, that measurements were meaningless.
He looked up through the top of the pod and saw the trunk rushing toward him. A cluster of external
housings was directly above: upside-down bubbles with suspended catwalks. Ten or twenty miles to his
left, he saw a portion of the tremendous crystalline girdle that circled Yggdrasil's waist and the secondary
tether that would keep Yggdrasil from sliding forward along the shaft during deceleration mode. The
tether was of woven viral monofilament a half mile thick, and the double bowline knot that fastened it had
been tied, with much tricky maneuvering, by a pair of space tugs. Tension would only make it stronger;
with the enormous forces involved, nobody wanted to take chances with extraneous fittings.
Bram noticed that at the moment Yggdrasil was floating free within its circlet; its momentum was
temporarily matched with that of the probe.
The trunk filled his view, and then the taffy pull of the counterline slowed the travelpod to a bobbing stop
Generated by ABC Amber LIT Converter, http://www.processtext.com/abclit.html
about a half mile below the entry blister.
Bram uttered a mild expletive as he found that the fist-size electric trolley that was supposed to wind him
in the rest of the way was out of order.
For a moment he was tempted to exercise a year-captain's prerogatives and signal the hub to reel him in.
But he was only a couple of hundred feet from his destination, and the pod's weight was negligible added
to his own, even under one-g acceleration. A half hour's worth of muscle power would do it.
With a sigh, he bent to the two-handed windlass and began cranking.
"That ought to do it," Bram agreed.
He tore his gaze away from the massive helical housing of the high-capacity pump. There was a final
gurgle that shook the floor as the last of a half million gallons of chemical solution was forced deep into
Yggdrasil's sapwood.
The tree systems officer and her hovering assistant gave him bland stares. "I thought the best way to
calm Yggdrasil down would be to smooth out the peaks and valleys in phytochrome balance," the TSO
said with professional briskness. "There was too extreme a swing between the two pigment forms, and it
was driving Yggdrasil crazy."
She gauged his expression for signs of comprehension, apparently decided in his favor, and went on.
"You see, the problem is the growing Doppler shift. Unfortunately, all the far-red light comes from the
same direction as the fusion light, so that side of the tree's overstimulated. The phytochrome keeps
changing back and forth between the far-red-absorbing form and the sunlight-absorbing form, then back
again."
Her assistant, even younger than she was, nodded agreement. They were both being patient with the old
dodderer.
"Yes, yes," Bram said quickly. "I'm sure you took the right approach."
The assistant cleared his throat and glanced at his boss before speaking. "And at the same time, there's
the problem of blue light tropisms at theopposite side of the tree. Where the band of up-shifted light is.
Yggie's hormones are working overtime to cope. And you can imagine whatthat does to his biorhythms."
"I can understand why your department was so concerned," Bram told them in his best sober manner.
They both beamed at him.
"So we added a healthy dose of vitamin A to the tranquilizer to damp down beta-carotene activity," the
assistant finished triumphantly.
"Fine," Bram said with a judicious nod. He looked around for a way to make his escape. "Well, that
seems to take care of it, so I'll—"
"Of course, you'll want to review our total hormone strategy while you're here, Captain," Jao's
granddaughter said. "Shall we start with the tree-turning maneuver?"
Bram gave in to the inevitable and let her lead him over to the far end of the hollow, where a battery of
Generated by ABC Amber LIT Converter, http://www.processtext.com/abclit.html
young technicians, wearing the leaf tabards that seemed to be the working costume of the new
generation, busily tended the array of giant fermentation tanks where hormone synthesis started.
A half hour later, his eyes slightly glazed, Bram found himself blessedly alone in the brilliant corridor that
ran through the trunk's heartwood. Alcoves branched off on either side, each with its neatly painted street
sign. Here, forty miles beneath Yggdrasil's bark, a lot of specialized work went on—plastics
manufacturing using leaf sugars as feedstock, the Message broadcasting facility whose vital work could
not be interrupted by yearly bough migrations, the central observatory.
There was also a recreation complex with guest suites, increasingly popular with the younger set and the
advanced retroyouth crowd, with facilities for sports, swimming, and small-craft sailing. After Yggdrasil
left the galaxy and acceleration ceased, it would be a center for such weightless pursuits as flying,
flat-trajectory handball, three-dimensional ballet, and, Bram didn't doubt, free-fall sex.
Bram paused to look at the bulletin board. Some members of the trunk staff were choosing up sides for
a game of teamball in what would eventually be the flydome. Bram was tempted to join them. But he
knew that he'd be invited only through courtesy and deference to his position. At his present
chronological age, he'd only be a liability to whatever team was willing to suffer him; better stick to
playing with his peers on the occasional Tenday.
Feeling pleasurably sorry for himself—refraining from reminding himself that he was not as old as he had
been twenty years ago—he gave the bulletin board a regretful last glance and set off down the long
arcade toward the observatory.
At least that was one treat he could give himself.
Jun Davd looked up from his work and smiled at Bram with a third set of teeth that were as white and
flawless as they had been when he had grown them a quarter century ago.
"Nice of you to play truant just so's you can come visit an old man," he said.
"The captainnever plays truant," Bram said, smiling back. "Everything I do isalways in the line of duty."
He raised both hands, and they touched palms in the old gesture.
Jun Davd chuckled. "So your duty brought you up to Yggdrasil's attic to rummage through the stars."
He was bent, frail, attenuated, but in remarkably good shape. Bram guessed that his biological age was
down to about eighty. There were even traces of gray in the cap of white curls. Flesh was returning to the
dark, mummified face, filling in the wrinkles. They had gotten to Jun Davd just in time.
"Is that what they look like now?" Bram asked, gesturing at the extrapolated display Jun Davd had been
studying when he came in. The screen showed a splendid panorama of multicolored stars, glowing
clouds, and luminous streamers swimming past in relative motion. Quite a few of the stars had disks.
"More or less," Jun Davd said. "The computer's having a hard time keeping up. That nice orange star
you see coming toward you has been reconstructed from gamma rays in the
ten-to-the-minus-six-nanometer range. The light that kills. The rear view's even more of a challenge.
We're seeingthose stars by ultralong radio waves—past the hundred-kilometer range. We've got almost
a thousand miles of wire with a weight on the end trailing behind us for a dipole antenna, and I really
could use a couple of thousand miles more except that I haven't been able to figure a way to keep the
