Orion gave the can a vexed look, and chucked it back onto the sand.
An hour later they stopped and set up camp for the night. Ozzie and Orion pitched their tent on a small rise several hundreds yards from the river, then set about washing socks and shirts before the last of the light vanished. Ozzie would have loved to dive right in and give himself a decent clean, but even though they still hadn’t seen a single living creature on this world, he just couldn’t quite bring himself to trust the water. Too many late student nights with a pizza, a couple of six-packs, some grass and a bad sci-fi DVD. God only knew what lurked along the bottom of the river, maybe nothing, but he certainly wasn’t going to wind up with alien eggs hatching out of his ass thank you. All of a sudden, the long evenings spent lazing around in the Ice Citadel’s hot pools didn’t seem so bad after all.
They were making their way back up to the tent when Orion stopped and said, ‘There’s a light.’
Ozzie looked down the canyon where the boy was pointing. A tiny golden spark was shining a long way downstream. He wasn’t even sure it was on their side of the river. His retinal insert zoom function couldn’t get a clear image, no matter how high the magnification, it remained a flickering blur. When he switched to infrared, it barely registered. Not a fire, then.
‘Probably someone else walking the path,’ he said with a reassurance he didn’t feel.
Tochee had seen the light as well, though the alien’s eye was unable to focus on it either. They kept watching it as they ate their evening meal of tasteless fruit and cold water, but it wasn’t moving. Ozzie and Tochee took turns through the night to make sure it didn’t come any closer. It was Ozzie who got the midnight to morning shift. He sat on a flattish rock beside the tent, dressed in his cords and check shirt, with his sleeping bag wrapped round his shoulders like a blanket. The river murmured away quietly, and occasionally he heard a low rattling wheeze from Tochee which he classed as alien snoring; other than that there was only the deep silence he would always associate with this world.
A brilliant multitude of stars shone down through the cloudless, moonless sky. He’d never seen so many before, not even when he went worldwalking on new Commonwealth worlds before they were contaminated by civilization’s light pollution. There was one hazy nebula, four or five time larger than Earth’s moon, which kept drawing his attention. It bent sharply at one end, with a reddish spike protruding away from the main haze. He couldn’t remember any astronomical phenomenon remotely like that being close to the Commonwealth. The Devil’s Tail, he named it. Shame nobody would ever know.
In the wilderness hours just before dawn he heard voices. He sat up immediately, unsure if he’d been drifting off to sleep. They could have been the start of some dream. But they weren’t human voices, or at least not ones speaking any language he recognized.
The spark of light hadn’t moved. He switched his inserts to infrared and slowly scanned round, turning a complete circle.
The voices came again. Definitely not a dream. They swept past him, causing him to turn so fast he almost lost his balance. Several of them babbling together. A non-human language. They sounded urgent. Frightened.
But it was only the sound. Nothing moved in the canyon. Nothing physical.
He almost asked; ‘Who’s there?’ Except that really was the stuff of late-night horror DVDs. Dumb.
Whispers slithered past him, somebody – something – whimpering into the distance. Ozzie dropped the sleeping bag and held his arms out, concentrating on his hands, trying to feel air being stirred, the tiniest hint of movement. He closed his eyes, knowing that a visual sense was no longer any use to him. Listening, stroking the air. The sound came again, conjuring up the old phrase voices on the wind. He heard what was said, and repeated it back to them softly. It made no difference. They carried on past him, paying no attention.
That was how Orion found him as the first wave of a pale dawn lifted over the canyon wall: standing motionless with arms outstretched like some religious statue, mumbling words in an alien tongue. The boy clambered out of the tent, rubbing sleep from his eyes as he yawned. ‘What are you doing?’
Ozzie sighed and let his arms down with a suspiciously yoga-like sweeping motion. He gave Orion an inscrutable grin. ‘Talking to the ghosts.’
Orion’s head whipped round, trying to find . . . anything. ‘Are you all right? Did you hit your head or something?’
‘Not since that bar on Lothian, and that was years ago. This world is haunted.’
‘Oh come on, Ozzie, that’s not funny. Not here. This whole planet is creepy.’
‘I know, man. I’m sorry. But I did hear something, like a bunch of people or aliens.’
‘The Silfen?’
‘No, I know their language. I don’t know what these guys were saying, but you get a feel from the tone. They were sad, or frightened. Maybe both.’
‘Hey, quit it! I don’t like this.’
‘Yeah. I know. I think that’s the point, man.’
‘The point of what?’
‘Whatever I experienced.’ He frowned. ‘What did I experience? Accepted there’s no such thing as ghosts, so . . . some kind of projection? Bit childish just to spook travellers. I mean, why not go the whole hog and put a white sheet over your head and jump out on them from behind a rock?’
‘You said the Silfen did have an afterlife,’ Orion said quietly.
Ozzie gave him a thoughtful look. ‘You really do pay attention, don’t you?’
‘Sometimes.’ The boy shrugged as he smirked.
‘Okay then, let’s think about this. None of our electronics are working, so the ghosts can’t be any kind of normal projection, holograms, sound focus, that kind of crap. The Silfen are active here, which implies it must be happening with their knowledge or consent.’
‘Unless it’s them doing it,’ Orion said, suddenly excited. ‘There’s nothing alive here. We haven’t seen any animals or insects. Maybe this is their afterworld, where all the Silfen ghosts live.’
Ozzie grimaced, and looked round the stark, massive canyon. ‘Somehow I think not. I’d expect something a little more impressive. But I could be wrong.’ He finished up by looking along the canyon. ‘Yo, can’t see the light anymore, either.’
Tochee slithered up between them, raising a limb of manipulator flesh. What’s happening? the patterns in its eye asked.
‘This should test our vocabulary,’ Ozzie muttered.

By mid-morning, they could see the black pillars ahead were indeed trees. Even by this world’s standards they were giants, perfect thin cones reaching over a hundred and fifty metres into the air. They had been planted in a double row, a kilometre to the side of the river, forming an impressive avenue down the canyon.
‘Somebody does live here, then,’ Orion said as they drew near to the start of the avenue.
‘Looks that way.’ Ozzie tilted his head back to see the top of the first trees. ‘You know, either they’re made out of a wood harder than steel, or there’s hardly any wind here, ever.’
‘Is that important?’
‘I dunno, dude. But it’s definitely a spike on the bizarro graph.’
Orion giggled. ‘This whole place is a spike.’
‘I’m not arguing.’
An hour later, when the canyon walls straightened out, allowing them to see ahead for miles, they made out a group of figures walking along the avenue ahead of them. Seven people, a long way in front, moving at a steady pace.
Bipeds like you, Tochee’s patterns declared. They made the light last night.
Could have done, Ozzie wrote.
They move slower than us. We can catch them today if we increase speed.
Ozzie had been thinking the same thing. Of course if he really wanted to attract their attention there were several flares left in his backpack, though he didn’t want to use them for anything less than a genuine emergency. And the group in front would have to be looking round at the right moment. He was slightly
surprised they hadn’t seen them already, especially given the way Tochee’s fabulous technicolour coating clashed against the drab ironstone.
Speeding up will be hard on us. We will reach them eventually.
Agreed.
In the afternoon, when they’d been walking down the empty avenue for several hours, they came to the first ruin. A small stream wriggled across the canyon, it ran from the base of the cliff wall down to the river, crossing through the avenue at right angles. At some time long ago, a simple curved stone bridge had carried the path over it. Now all that was left were the solid foundations on either side, sticking up from the dusty ground like a set of broken teeth.
There were gentle grooves in the stonework, resembling the trails snakes left in sand. Ozzie couldn’t tell if they were natural wind-erosions or ancient carvings. Thinking about the trees again, he suspected carvings. How long it would take for them to wear away like this he had no idea. Centuries, at least.
‘I wish my arrays were working,’ he sighed. ‘They could carbon-date this right down to the afternoon it was built.’
‘Really?’
‘Pretty close, yeah.’ It was always slightly unnerving how little Orion knew about technology. He had to be careful what he said, especially jokingly, which wasn’t an Ozzie trait. But the boy tended to take everything he said as gospel.
They splashed through the little stream, and carried on walking. Ozzie resisted the urge to carve his name into the bridge. He was mildly surprised no one else had, especially the guys who’d left the coke can.
By the time they made camp they’d passed another ruined bridge, as well as a big circular depression in the ground whose edges were made from tight-fitting stone blocks. Neither archaeological remnant provided any clue as to what kind of creatures had built them. A bridge was a pretty basic design for any species, as were sturdy foundations, which is what Ozzie suspected the circle to be.
Through the day, they’d managed to close the distance on the group of travellers in front of them to about a mile. Once they got the tent up, the gold light became visible in the gathering darkness.
‘That’s just about where they are,’ Orion said. ‘You should fire a flare, Ozzie. There’s no way they can’t see it now.’
Ozzie gazed at the steady point of light. ‘They know we’re here. If they don’t want to talk to us, there’s no sense in trying to force them.’
Orion nodded cheerfully, and cut into one of the big fruits. ‘I get that about people now. You can’t rush somebody who doesn’t want to be rushed, right?’
‘You’re learning.’
‘So I let the girl set the pace.’
‘Yes, that’s right.’
‘And she’ll always find a way to tell me when she’s ready to go to bed? You’re sure about that?’
‘Uh, yeah.’ Ozzie was beginning to dread evenings round the camp fire. The boy did have an amazingly one-track mind. ‘But, look, man, it’s going to be subtle. You’ve got to be alert and in tune.’
‘Like how do you mean?’
‘Okay, if she’s happy for the date to go on as long as you want, that’s a good sign.’
‘I thought you said don’t try to get her to bed on the first date?’
‘Yes, yes, that’s right. But this is the second date, or later.’
‘Okay. So it goes on all night. Do I ask them home, or will they ask me?’
‘I don’t know, man. It depends on the girl, okay. Use your judgement.’
‘But, Ozzie, I haven’t got any, that’s why I ask you.’
‘Want another chat-up line?’ He’d found that was always a good way to make Orion stop, although the cost to his own dignity was always painfully high.
‘Yeah!’
‘All right. But you’ve got to have a ton of self-confidence for this one, okay, show no fear. Is it me or do you always look this good?’
‘Maybe,’ Orion said dubiously. ‘But you’d have to have a good follow-on line.’
‘Hey, I’m just showing you how to open the door, once you’re in the room you’re on your own.’
The voices returned in the deep of night. This time they were slightly louder, occurring more frequently.
Orion woke with a start as one set passed right beside the tent. Ozzie was already sitting up in his sleeping bag, listening to what was spoken and the way it was said.
‘It is ghosts, isn’t it?’ Orion said solemnly.
‘Kinda looks that way, yeah. You scared, man?’
‘Ozzie! It’s ghosts!’
‘Right. Well I’m scared, just in case you wanted to know.’ He wriggled out of his sleeping bag and unzipped the tent. The night air was alive with sound, hundreds of voices that swirled chaotically around their little camp. He walked out into their midst, turning – into daylight. His feet were standing on a lush carpet of blue-green grass which covered the canyon floor, along with trees and thick bushes. The avenue of trees had been replaced by a road built from stone cobbles. Strange five-legged bovine animals pulled wooden carts along it, piled high with barrels and some local version of hay. The drivers were aliens that looked like pear-shaped jellyfish, with hundreds of slender tendrils emerging from their lower half, serving as both legs and arms. Individually weak, the wax-white tendrils would twine together to produce a stronger limb for whatever use was required. Dozens of them were sliding along the road, the tips of their tendrils twisting and scrabbling like impaled worms to move them forward. They called to each other in low gurgling voices.
One of the carts was heading straight for Ozzie. He waved his arms frantically. ‘Hey, watch what . . .’ The driver obviously couldn’t see him, or the tent, or Orion standing at his side. He grabbed a frozen Orion and hauled him aside, falling off the side of the road – into night time.
‘Fuck me!’ Ozzie grunted. He raised his head and looked around. Nothing had changed. Stars glittered in the night sky, casting a faint illumination. The avenue of trees stood impassively along the side of the quiet river, marking the course of the old road.
‘Wow!’ Orion gushed. ‘Cool.’
‘Uh?’
Starlight showed the boy’s wide smile. ‘Don’t you get it? This canyon is a time machine, like the Silfen paths are wormholes. How smooth is that?’
‘That was just an image, man,’ Ozzie said, somewhat stiffly as he clambered back to his feet, brushing sand off his shorts. ‘It’s showing us what used to be here.’
‘I smelt them, Ozzie, it was like vinegar. That was real, not an image. We were there in the past. Anyway, you thought we were there, why else did you dive for cover?’
‘I was surprised, that’s all, and I didn’t know what level the image extended to. People have gotten themselves hurt in TSI, you know, man.’
‘You were scared.’ Orion flung his arms wide, laughing wildly at the canyon wall. ‘Hey, you scared Ozzie. Bad time machine.’
‘This is not—’ Ozzie got a grip, although he’d noticed the smell, too. He looked along the avenue, checking on the golden light from the other group. It was still there, unmoving. The ghost voices had come back, slipping sinuously through the air. ‘Damn, this place is weird.’
‘Ozzie!’ Orion gasped.
One of the jellyfish aliens was slipping past them, wrapped in its own little nimbus of daylight. Tochee pushed its icewhale fur blanket aside, rearing up on its locomotion ridges in shock as the seemingly solid apparition glided along.
What was that?
Tochee’s eye patterns were shining so brightly Ozzie half-expected Orion to see them. He shrugged – they certainly didn’t have anything like the vocabulary for time-travelling spooks. When he glanced round, the lone jelly alien had gone.
‘I think we’d better get off the avenue. It’s only a few hours to dawn. We should try and get some rest.’
‘Oh, Ozzie, this is wonderful. We might wind up finishing this journey before we started. I could go back to Silvergalde and stop my parents from ever leaving.’
‘Look, man, I know you think a time machine is a groovy thing, but take it from me there are quantum fundamentals that prevent it from happening. Okay? I know what this looks like, but it isn’t real.’
Orion was about to answer when a small mechanical car appeared, with two jelly aliens sitting in the cab. Smoke and steam belched furiously from stumpy chimneys in its rear. The boy drew in a sharp breath and swayed backwards. ‘I think maybe you’re right. We’ll get run over here.’
Ozzie was sorely tempted to just stand there and let one of the apparitions glide right through him. But they looked so damn real!
The three of them gathered up their packs and hurried away from the avenue. As soon as they were outside the line of trees the voices faded away, although they never fell completely quiet. Ozzie and Orion sat against a boulder, wrapping their sleeping bags round them. Every now and then opalescent light would burst out of the avenue, silhouetting the bottom of the trees as the long-dead aliens walked their old road. After a while Ozzie stopped trying to figure it out, and closed his eyes.

‘I’ve got a theory,’ Orion said eagerly as they munched on their tasteless breakfast. ‘I think Sara walked down this canyon. That’s why she’s still alive after so long. The canyon brought her into the future.’
‘It’s not a time machine,’ Ozzie said for what must have been the tenth time. ‘Time cannot flow backwards, you cannot move back through time. It is a one-way current. Period, dude.’
‘She moved forward.’
‘Okay, not so difficult. Even we can do that.’
‘Can we?’ Orion was fascinated.
‘Well . . . in theory, yeah. The internal structure of a wormhole can be modified so its timeframe is desynchronized. In other words, you go in at one end, and a week later you come out of the other. But, for you, only a second has elapsed. I’m pretty sure that’s what’s been happening on the Silfen paths. It certainly makes sense, especially when you think of people like Sara.’
‘Have you done it with your wormholes?’
‘No. It’s very complicated. We don’t have the technology to match the math yet.’ He grunted in disapproval. ‘Maybe we will by the time you and I make it back.’
