âConversion stations?' Tack asked.
âOne such station, over Mars, converts microwave energy into the full spectrum of lightâfrom infrared to ultravioletâwhich serves as our replacement for the sun mirrors destroyed by the Umbrathane. It is the reason that planet is now no longer entirely red.'
Tack considered that. âYou said just a fraction?'
âMost of that beam hitting the dish here, is used to power the wormholeâthe time tunnel. You have to understand that we originally built the tap specifically for that purpose, and that the greening of Mars became just a side benefit. Tap and wormhole are inextricably linked and neither, once created, can be turned off. There is, in fact, no physical means of turning off the sun tap as the antigravity fields that sustain its position also focus the beamâas I mentioned-but if you did, the wormhole would collapse catastrophically and Sauros would be obliterated by the feedback. Also, if the wormhole was independently collapsed, the energy surge would vaporize New London. The project was therefore a
total
commitment.'
They now became weightless inside the mantisal as it dropped past the outer rim of New London, and soon Tack observed that, just like a coin, the city had two sides. When the construct swung in towards the other side, Tack felt his stomach flip and bit down on a sudden nausea. Now he felt the pull of gravity from the second side as they descended towards a building on the very edge of a city, which sprawled across the entire underside of the disc. This structure was shaped like the rear half of a luxury liner, but standing on end so its stern was pointing into space. Except this would have been a liner that made
Titanic
look like a lifeboat. The mantisal now curved in towards the âdeck' side of the building, where other structures protruded at right angles. Tack saw that, like a silver foam, thousands of mantisals were already attached to these protrusions. Eventually they came in amidst them and descended onto a platform resembling a weird melding of a giant oyster shell and a helipad.
Withdrawing his hands from the mantisal's eyes, Saphothere said, âYou remember the mask in your pack? You'll need it to get to the entrance, as it's vacuum up here.' He gestured to an oval door at the juncture of the landing platform with the main building. âYou'll have to run, though.'
Tack opened his pack and took out the mask. When Saphothere had originally explained its function to him, Tack had hoped he would never have to use it. It looked organic, like the sliced-off face of a huge green cricket, its interior glistening wet. As he pressed it against his face, its soft interior flowed around his features, moulding itself to him. For a moment he was blind, then a vision screen switched on, with complementary displays arrayed along the bottom. Breathing involved only slightly more effort than usual. Apparently the mask stored pure oxygenâafter sucking it in from its surroundingsâand, when being worn, released it.
âCome on now,' urged Saphothere, his own mask in place as he leapt out. Tack followed him, running for the door. Initially his skin felt frozen, then suddenly it was burning. He saw vapour rising off his clothes and dissipating. Saphothere, trotting along beside him, seemed completely at ease in this environment. As they reached the oval door, Tack glanced back to see the mantisal floating over to one side of the landing pad, where others of its kind were gathered. Grabbing the protruding handle, Saphothere pulled the door open and led the way into an oblate airlock chamber. As soon as he closed that door, air began blasting in, and after a moment they could remove their masks.
âNow what?' Tack asked.
Saphothere proceeded through the next door into a chaos of sound and colour. Tack could hardly take it all in: a vast chamber containing dwellings in all shapes and sizes suspended in gleaming orthogonal scaffolds; gardens and parks, some of them even running vertically; walkways ribboning through the air; transports of every kind hurtling all about the place; and Heliothane everywhere, thousands upon thousands of them. Glancing at Saphothere he saw the man was operating his palm computer.
âYou are too slow and too weak, so would get killed in here'âhe gestured to the surrounding mayhemââwithin minutes, probably by accident. This is not for you yet.' So saying, Saphothere operated some other control on his computer. Tack felt the all-too-familiar sensation of a reprogramming link going in. He tried to object, but instead simply shut down. Everything started to grey out and the last thing he felt was Saphothere catching him as he fell.

RAIN LIKE A VERTICAL sea hammered upon her and, slipping in the mud, Polly went down on her face. Her nostrils filled with the stench of decaying vegetation and in the darkness she could hear things hooting and screeching.
âYes, I knowânot a good place to be,' she said, then wished she hadn't spoken when the animal noises fell silent.
Pushing herself upright, she looked around at the darkness and at huge trees looming behind curtains of rain.
âYou've got nothing to say?' she asked him nervously, terrified she might now be genuinely alone.
Oh, always something to say. But at present I'm trying to use one of Muse'
s military logistics programs to calculate your acceleration back through time.
âYou'
ll be able to predict what era I
'
ll arrive in next?
' Polly subvocalized, sure she could hear baleful movements out there.
Well, I have some dates to work with ⦠within vague limits. Thus far it would seem your acceleration is exponential, though what the exponent is it's difficult to ascertain. All I do know is that if the increase continues at its present rate ⦠a few jumps more and you
'
ll be going back millions of years at a time.
âYou're not serious?
'
Oh yeah, but, as I said, the parameters are vague. If you follow the curve I
'
m now trying to plot, you
'
ll end up off the graphâachieving a jump that is infinite. But then I might only be viewing part of that curve and who's to say you'll be following a curve anyway? Thing is, you are now learning to control the shifts, and Christ knows what other factors might come into play. The next one might easily be one year or one million years.
âOh, screw this,' Polly said out loud and reached down inside herself to grasp hold of that webwork and bend it to her will. This time there was no transition over that previous black sea and she was immediately into that Euclidian space she could manipulate, if only in a small way. She gave it a few seconds only, then pulled herself out, dropping down on her back into soft leaf litter in a raucous daylit forest. She gasped in a lungful of cold morning air.
Of course, every time you do that, you just screw up my calculations further.
Polly did not know whether to laugh or cry.
Â
CHENG-YI DRAGGED HIMSELF OUT from under the mounded dead and looked around in disbelief. The attacking unit of the People's Army had bayoneted the survivors and the wounded ponies, then looted the bodies. All that now remained of the largest robber band in Miyi county was butchered corpses strewn along the valley. That none of their attackers had dragged Cheng-yi out and searched him he put down to his being covered in blood and the plenitude of loot elsewhere. Climbing unsteadily to his feet, Cheng visually checked himself from head to foot. None of the blood appeared to be his own, which was miraculous considering he had been riding beside Lao when the machine gun opened up, and there was not much left of
him
that was identifiable. Cheng gave a little dance and shook his fists at the sky, then he looked round again, completely at a loss.
What little drug smuggling or gun running they had managed across the Himalayas since Mao's revolution, would not be available to him alone. And also, since that revolution, pickings had been poor in the Xiang regionâmost of the thieving already done by Party officials. Cheng was damned if he was going to rejoin China's current society: thankless toil and the grey and boring
clothing did not appeal to him. One option remained: he would head towards the coast, for Kowloon and Hong Kong, and see how his fortunes would fare. Not for one moment, as he exchanged his clothing for the best available remaining on the corpses, and looted them of anything the soldiers had left, did he feel any grief. They hadn't been a bad lot, but none of them had really appreciated his qualities and, anyway, his emotional spectrum encompassed only terror and lust. The former came into play again when, just as he was ready to set out, the monster came.
The huge and horrible thing fed on the dead. He saw it bow down over the body of a pony and suck it down with a crunching gulping. The human corpses it took down with less trouble. Crouched behind a rock, Cheng-yi sobbed with terror as he listened to the macabre feasting, then when the sounds ceased, he choked back his sobs and held his breath. Perhaps it was gone now? Perhaps it had never been there â¦
Cheng-yi looked up straight into the mouth of hell poised above him and screamed. The mouth turned away and, from the flank behind, one of the monster's scales fell and thudded in the dust beside the Chinaman. He watched as the scale, at first leaf-like, coiled up into a cylinder as if rapidly drying. Lust was Cheng's next emotion, and he did not hesitate to grab the thing up and pull it up over his forearm. Then, the monster gone, he wondered what madness it was that had made him see such monstrous visions. But this was not his last.
Engineer Goron:
It was some staffer of Maxell's who had the idea of using cerebral programming on the next torbearer we managed to intercept. Sir Alex seemed the best option as he had been combat trained from birth. Our team had eighteen hours to work on him before his next shift and all seemed to go well: the programming took and there was even time to provide him with physical augmentation and a Pedagogue weapons' instruction download. Apparently, though he accepted our weapons, he utterly refused to shed his armour. But even with his armour and his weapons and his new abilities, he must have failed. The team, remaining at the location where they had intercepted Sir Alex while they recharged their mantisals via a portable fusion/displacement generator, were attacked by the beast only minutes after his concurrent arrival beyond the Nodus. So we can only suppose that Cowl killed the man, but was angry enough to retaliate directly.

P
EDAGOGUE WAS AN UNSEEN presence directly downloading information into his mind and, with the true brutality of a surgeon, wrenching into shape those structures in his mind that could utilize it. But this, this he didn't understand:
The trip was due to take another five hours. Tack
knew
there were three ramscoop fusion engines, set on outriders protruding from the main cylindrical body of the ship, belching white blades of flame. Mercury resembled a cindered sphere to his left, but with a sprawl of bright-silver installations spread in a maze across its sooty flank and cigar-shaped stations orbiting it. Tack was apparently standing before one of the triangular screens that ringed the bridge sphereâearlier in its life, the only place possible for humans to survive here. Now the ship was lethally radioactive. How such a vessel managed to operate
in these conditions Tack was only momentarily bewildered to consider, but then, almost off-handedly, he dowsed the extent and capabilities of Heliothane materials and field technology.
Ahead, the sun loomed largeâlike a hole cut through space into some hellish furnaceâand against it was silhouetted the tap itself. The thing was stupendous, like some vast tanker crossing an ocean of fire.
âWhy ⦠?' He didn't really voice the questionâit was just there.
Would you prefer â¦
Instantly Tack found himself submersed in some viscous clear fluid, and in a world of pain. He couldn't scream as the fluid was in his mouth and lungs and, as he began to struggle, he discerned optic cables snaking away from the back of his head. Looking down, he saw himself flayed, red muscle revealed, tubes and wires connected down the length of him, metal cuffs enclosing his joints, the cowled head of some surgical robot excavating into the side of his chest. Then the horrific vision was gone and he was back on the sun ship, gasping and clutching at his chest, shivering. But the pain faded and the memory of pain swiftly blurred.
âWhen we have rebuilt you, you will be more sufficient to your task.'
The disembodied words meant the same in every one of the many different languages now available to him, for Pedagogue was speaking to him in every language that he now knew. He thought of Heliothane weapons, realized he knew how to strip and rebuild a multi-purpose carbine, and how to program molecular catalysers. And these were just the tip of the berg of knowledge expanding in his mind.
âI have questions â¦'
âAnd I have answers,' Pedagogue told him flatly.
Tack reached out, touched the screen, actually felt its warmth. âCowl must overcome the temporal inertia of four billion years to succeed.' He tilted his head. âI see, one billion.' Now he knew the Nodus Cowl had travelled a few centuries behind was situated just before the Precambrian explosionâwhen complex life really began to take hold. âThat inertiaâto overcome it Cowl must do something ⦠cataclysmic. And even if he succeeds he'll just push himself and his new history down to the bottom of the probability slope.'
âCataclysmic ⦠Nodus. What maintains the relative position of the alternates on the slope? Why does father killing confine you in the new time-line you have created by that act, down the probability slope, rather than make that line the main one?'
âCause and effect. The paradox shoves you down the slope.'
âCorrect. But that paradox can only come into being because you are
contradicting
what came before. You are acting counter to temporal
momentum
. Before the Nodus there is virtually zero momentum and therefore zero to contradict.'
Tack saw it then. He conceived the image of time as a sheet tossed over a table, against the surface of which already rested a long rod, the uppermost point on the sheet, where it was lifted along the length of the rod, being the main line. The rod was also tilted up from the edge of the table, so that the slope of sheet, down from it on either side, grew longer the further in from the edge of the table you went. The edge of the table was the Nodus itself, and the rod protruding from the edge was held in a hand that could, given sufficient pressure, swing the rod, thus altering the position of the high point in the sheet and the slopes on either side. That hand belonged to Cowl. Tack swallowed dryly, seeing that he had no choice but to believe what he was being told: if someone's hand is hovering over the detonator switch of an atomic bomb, you do not hesitate to shoot them should you have the opportunity; you do not ask what their intentions are.
âThere's more I need to know.'
âYes â¦'
In his mind he now sensed a wave of information, poised just at the edge of perception and ready to break over him. Before him the triangular screens turned black for a second, then came back on to show an entirely different display. He stepped forward, for a moment was submerged in viscous fluid again, and briefly glimpsed his raised arm, skin growing back across it like white slime, the material of his tor grown to the size of his palm. Pain was a brief suf fusion, then he was standing on a walkway beside the glass of an aquarium wall behind which something shifted. A nightmare turned towards him.
Â
WELL, LOOK AT THE pretty horses now.
From the start the place had seemed idyllic: warm balmy sunshine, wild plums scattered below the trees fringing the forestâfed upon by small lemurs who maybe preferred the slightly decayed fruit for its intoxicant effectâamid lush green grass scattered with giant daisies and enough dry wood with which to make a fire for the coming night. But before she had a chance to set about gathering some, a herd of miniature horses galloped into viewâscattering the lemurs in panic. Polly knelt in the shadow of a tree to eat the plums she had
collected while she watched the cute creatures' antics. Then it had appeared, and now she crouched behind the same tree, the taser in her left hand and the automatic in her right.
You're way back now. Bastards like that died out about forty million years back.
The monster hurtled in on the pastoral scene with a scream like a klaxon. Swinging and clashing its parrot beak, it eviscerated one of the little horses, then took the head off another, and stamped its talon down on a third, while the rest of the herd fled. It began eating the pinioned animal, tearing it in half and tilting back its head to gobble down the quivering hindquarters. In moments it finished the first horse, then it strode across to another, pecking up a decollated head on the way. Before feasting on its third victim, it paused and shat out a spray of white excrement.
I think it's getting full now.
So it appeared, for the monstrous bird, after eating the head and forelegs of the third horse, was pecking at the rest in what now seemed a desultory manner. After a moment it gave up completely, scraped at the ground like a chicken, before letting out that klaxon squawk again and moving away.
And that was only a small one.
Polly was aghast, for the horrible creature had stood higher than herself and . its killer beak was the size of a bucket.
It's called Gastornis
, Nandru explained.
Seeing the bird was now some hundred metres away, Polly began to move out from under cover.
Wouldn't it be better to stay in the trees?
Ignoring this advice, she glanced all around to make sure there were no other unpleasant surprises in the offing, then ran over to where the bird had been feeding.
Are you insane?
Stooping, Polly grabbed a bloody chunk of the last little horse and ran for cover again.
âWaste not want not, as my mother always used to say,' she sang, running still deeper into the forest.
Later, with her stomach full of roast horse, she gazed out from her camp and noticed how her fire's glow reflected on eyes out there. After throwing a bone out towards them, she could hear things squabbling in the darkness over it. But at least they sounded small.

THE NIGHTMARE BORE THE shape of a man, but a tall, long-limbed man in whom the ranginess of the Heliothane had been taken to its extreme. It had no faceâits head was a slightly beaked, utterly featureless ovoid, of the same shiny beetle-black appearance as the majority of its naked body. However, as if this was not strange enough, the black carapace revealed a network of hyaline veins and ribs, so that, when the light caught the network, it looked as if something horribly skeletal stood there.
âA woman used a semi-AI prognostic program to predict the future development of human DNA, and on the basis of that started recombination experiments on her children. In her terms, her first experiment was a failure, though the offspring survived. Cowl was not a failure, so there is much speculation as to what those terms of hers were.'
Tack flinched as Cowl started to walk towards him, but the dark being was then frozen mid-stride as Pedagogue continued lecturing.
âWe don't know what external pressures were input, because DNA has no purpose in itself other than its own survival and procreation, so intelligence or physical strength are only increased should they have a direct bearing on that. Should the survival of human DNA entail you needing to lose your big brains and filter food out of the soil, you would all become worms. It can only be supposed that her program posited a future where the highest levels of intelligence, ruthlessness, speed and strength were required. Cowl killed his own mother while in her womb, thereafter escaping by internal caesarean much like a chick escaping from the egg with its beak spur.'
âBut he became one of the Heliothane,' Tack stated. The information was now just there, in his mind. He saw how Cowl's survival had initially depended on the Heliothane, how he had deliberately become a very valuable member of that society. It was not so difficultâruthlessness and intelligence being much admired. The misjudgement had killed many. One of them a top scientist called AstolereâSaphothere's sister.
âI see,' said Tack woodenly.
And see he did. He saw Callisto, a moon of Jupiter, exploding, with the blast contained in some unseen barrier and the moon just winking out of existence. Four hundred million Heliothane gone in less time than it took to draw breath.
âCowl, having made his alliance with the Umbrathane, and passing on much of his research, caused a temporal anomaly on Callisto, where his research facility was based, putting a pico-second future version of that moon in exactly the same place as the original. The physical composite of the two
moons, forced to exist however briefly in the same place, went in a fusion explosion, the energy generated thereby powering his flight, and that of the Umbrathane fleet, into the past.'
âAnd I am supposed to kill this ⦠creature?'
âYes, that is your task.'
Back aboard the virtual ship, Tack was bathed in incandescence. The screens now revealed a side view of the sun tap. It was a leviathan wood planer shaving the fiery surface of the sun, raft-like at its two extremes but humped in the middle. The view was filteredâit would have incinerated him otherwise. Then, suddenly, he was gazing upon the vast cliff that was just one side of the tap. This close it seemed to extend to infinity in every direction, beyond planetary scaleâimmensity impossible to encompass. He blinked and drew his attention away from it, studying his closer surroundings. The inside of the ship had become a furnace: plastics were beginning to smoke, coatings were peeling from metal surfaces, spots of red heat were appearing on bare metal, and smoke-hazed air being drawn away through vents. And so the unreal world Pedagogue had created came to an end. When the ship's fields collapsed, actinic light obliterated everything and Tack began to wake.
Â
SHE WAS RUNNING OUT of air, and now the force of her will was pushing the scale in some other way. She found herself being dragged sideways back into that dimension of black sea underlining a grey void, but drawing along with her part of the previous place. From the scale itself barely visible lines of light sprang out and turned back in on themselves, all looping at precisely the same distance out from it, so she appeared to rest at the centre of a huge, luminous dandelion clock. Then this spheroid took on a glassy quality, the light draining out of it and its surface splitting and coalescing into veins and ribs, as of water poured onto something greasy. Encaged in this cocoon she fell, gulping at nothing in the darkness, consciousness fading. But still she had some will left and attempted to force her way back into her own reality. Around her the black sea rose up, and gravity grabbed her and slammed her down on a floor of hyaline bones. She gasped in frigid air, grateful for each painful breath. Rolling upright, she found herself still encaged in the sphere, hovering now over frigid ground, a dark grey sky above, strange frozen trees to her right and a snowy plain to her left. Terrified that she would be snatched away from breathable air again, she scrabbled for a gap in the cage wall, but even as she found it and fell through, the cage itself began to fold away into that other place.
