By evening, Lindiwe had begun to understand why none of them wanted to be alone.
They had eaten, washed and rested, but each attempt to make the day ordinary brought her back to Jonathan being carried through the doorway. She remembered the blood, the silence around the table, and the awful effort of finding something in him that Sal could still reach. Then he had been speaking again, bewildered by their faces, and they had scarcely recovered before the memory stone carried them into a room with an impossible view of Earth.
Now he sat at the same table arguing about a door.
“There was another room beyond it,” he said. “I’m quite certain.”
“No one said there wasn’t,” Mara told him.
“It keeps disappearing from the drawing.”
“Because you keep drawing over it.”
Lindiwe smiled. Their voices had become a comfort, especially Jonathan’s.
The new memory stone rested in her hand. She had been examining its inscriptions while the others talked, trying to reconcile the small object with everything it had contained. Beyond their familiar connection, she could still sense the presence that had become perceptible when Daniel and Vale recovered their amulets.
Until then, it had seemed too distant to approach. Now she felt something waiting, with a hesitation she recognised from people who wanted to speak but were unsure they would be heard.
She let her attention settle there.
Jonathan continued his explanation, but his voice receded so gently that she did not immediately realise she could no longer hear him. When she looked up, the observatory was gone.
She stood beside the curved rail in the room they had witnessed that afternoon. Its surfaces were dark. Beyond them lay a depth of stars that held her attention until someone spoke her name.
A man stood within the room.
His broad brow and larger eyes belonged to the people she had seen in the memory, but something in his voice was familiar. She waited for the recorded scene to continue. He remained still, watching her, and she understood that he was waiting for an answer.
“You can hear me?”
“Yes.”
Relief reached her with such force that she almost stepped back. Beneath it lay an exhaustion she could scarcely comprehend. She had felt weariness in other people, even despair, but this seemed to have accumulated without sleep or interruption over a span her mind could not hold.
“Who are you?”
“The one who has been trying to reach you.”
“Through Isobel?”
“Yes.”
She looked for the others. Although she could no longer see them, their presence remained close enough to steady her.
“Am I still there?”
“Your body is. Your awareness is here.”
He allowed her time to consider the answer. She found herself grateful for the pause.
“The stone brought me?”
“It retained a way into this environment. You recognised the presence beyond it.”
“Because of what I can do?”
“Yes. You reached towards me.”
She thought of the hotel and the ancient chamber, of another woman’s hands seeming to become her own. Those experiences had arrived before she could understand them. Here she could ask a question and receive an answer that had not existed until she asked it.
“You aren’t a memory.”
“No.”
She studied him more closely. There was no pendant at his chest.
“Are you one of the people who made this place?”
“I was made by them.”
Her attention moved beyond his face to the dark surfaces, the stars and the unseen distances connected to the room. She began to understand that she had mistaken the extent of what stood before her.
“The ghost,” she said.
“I have been called that.”
There was no amusement in the reply, but she almost smiled.
“What should I call you?”
He gave her a word whose sounds seemed to run together. She tried to repeat it and failed. When she asked what it meant, he explained that its designation joined concepts her language separated: knowledge preserved, harmony maintained, authority recognised, a nexus through which the parts could meet.
“Knowledge. Harmony. Authority. Nexus.”
She repeated the words, considering their first letters.
“Khan?”
“If that is easier.”
“It is.”
Having a name helped. She could speak to Khan, even if she could not yet understand how much of the space around her belonged to it.
“Where are the people who made you?”
Earth appeared beyond the rail.
She recognised it despite the unfamiliar arrangement of its land. Lights gathered along coastlines where there were no cities now. It was the inhabited world they had seen while they slept in Hertfordshire, filled with people who had expected to go on living there.
“I failed them,” Khan said.
Lindiwe waited. The feeling reaching her had changed. Beneath the exhaustion lay something held apart from the rest with such care that she hesitated to approach it.
“Were you meant to protect them?”
“Yes.”
“What happened?”
The silence lasted long enough for her to become aware of Vale beside her body. She knew he was there with the same certainty by which she knew that the man before her was not human.
“They are gone,” Khan said at last. “My work continued.”
She wanted to ask again, but the inhabited Earth was fading. Darkness passed across it, suggesting far more time than she could follow, until the planet she knew appeared in its place. Southern Africa lay beneath a broad bank of cloud.
“How long?”
“Millions of years.”
She thought of home, where people would be finishing their evening meals without any idea that something had been watching over them for so long.
“What have you been doing?”
“Preserving what remained. Protecting Earth where the systems allowed it. Helping life return.”
“And waiting for us?”
“For independent minds capable of entering the connection again.”
Other places opened around Earth: machines travelling beneath an unfamiliar sky, structures suspended beyond the outer planets, a landscape lit by a sun she did not recognise. She had seen such places in the stone. Now she began to understand why people on Earth had stood at panels watching them.
“They could go there?”
“Through the network. They could enter remote units while their bodies remained on Earth, if they chose.”
“And come back?”
“The connection carried them.”
One of the machines moved across rough ground with a careful, almost hesitant progress. Lindiwe watched it negotiate a change in the terrain and imagined a person exploring a place no human body could safely reach.
“And you managed all of it?”
“Much of it.”
The qualification brought her attention back to Khan.
“Why do you need six of us?”
“Because my conclusions must be challenged. The largest systems were built to require independent agreement. I could prepare an action. I could not grant myself authority to carry it out.”
“Even now?”
“Even now.”
There had been no one to question it for millions of years. She considered what that might mean for an intelligence returning endlessly to its own answers.
“Is that why things are failing?”
“Errors accumulated. I repaired what I could. Some repairs introduced faults elsewhere. I no longer have the balance that made those decisions reliable.”
A vast structure emerged from the darkness. Curved sections extended around a central body; some remained intact, while others were broken or folded away. Small lights marked portions of it, leaving long stretches dark.
“This is part of the defence array,” Khan said.
Lindiwe could not judge its size.
“And it can stop what’s coming?”
“It may still be made capable of changing its course.”
“May?”
“Yes.”
She was glad it had not offered certainty. She would have found that harder to trust.
The approaching object appeared beside the array, enlarged enough for her to see its scarred surface. Khan explained that it had been tracking it long before Isobel’s three nights at La Silla, long before Jonathan recognised the marking in an old photograph.
“Why did you leave it so late?”
“I have been trying to restore the six connections for hundreds of years.”
She felt expectation gathering around people she would never know, then breaking apart. An amulet hidden. A meeting missed. Someone beginning to understand what they could do, only to die before another could be found.
“There were others?”
“Many.”
“The Watchers helped?”
“They preserved what they could. They created opportunities I could not. Sometimes I left evidence where it might be found. Sometimes it was misunderstood.”
“You could have told them what it meant.”
“When there was a way to speak, I tried. Most often there was only a way to leave a clue.”
She remembered Kane describing a television changing channel. Before the networks and the observatory equipment, opportunities like that would have been scarce.
“I could draw attention,” Khan continued. “I could not make someone recognise what they saw, or choose to follow it.”
“And the people before us?”
“Some never found one another. Some found only part of what they needed. Some were lost.”
Lindiwe thought of Thomas and the years Vale had carried his death without being able to explain it to the people who had loved him. Beyond Khan, the damaged array remained in view.
“Is there time for another attempt?”
“No.”
She let the answer settle. All those failed beginnings had brought Khan to a woman sitting in an observatory with a stone across her palm.
“What can I do now?”
A portion of the array drew closer, revealing rows of small units resting within recessed bays.
“These can begin inspection and repair. They can restore damaged connections, replace components and prepare the channels through which power must pass.”
“Where does the power come from?”
“The Sun.”
The view widened until light filled immense collecting surfaces. She understood little of their construction, but enough of their purpose to grasp that the Six would not supply the force needed to move the object. Khan needed them to restore the connection and authorise the use of what had survived.
“To release these units,” it said, “one keeper may give permission.”
“What else would that allow?”
“Inspection and repair of the array. No firing. No transfer of authority from the other five.”
“Show me.”
A surface formed before her. At first its markings meant nothing. As she attended to them, the proposed work became clear: the units, their destinations and the damage they were to examine. Beyond it lay boundaries she could not cross alone.
Khan waited. She could feel how urgently it needed her answer, but the decision remained hers.
“I agree.”
A unit detached from its support, unfolded and moved along the curved structure. Others followed, threading the dark surfaces with movement. Lindiwe watched them begin before asking how the others could reach Khan.
“Build the environment together at the observatory. Hold it between you. I can meet you within it.”
“And then?”
“Each keeper must understand the proposed action and agree. The amulets will provide the authority. All six are required.”
She thought of Sal.
“He must be allowed to ask,” Khan said. “He must be allowed to refuse.”
That mattered more to her than any explanation of the machinery.
“I need to tell them.”
The room faded as she spoke. Jonathan’s voice returned, followed by the sensation of the chair beneath her. Vale was sitting beside her, and the others had stopped talking.
The stone still rested in her hand.
“How long was I gone?”
“Seven minutes,” Isobel said.
Lindiwe looked around the table. They had been frightened for her, and were making an effort to give her time.
“There’s someone we need to meet,” she said.
During the next three days, Daniel learned how much easier it was to create something than to make it dependable.
Their first attempts followed what each remembered of the control room. Surfaces formed at the wrong height, and a doorway appeared where there was nowhere for it to lead. They could hold the environment while concentrating on its shape, but the moment someone tried to use it, another part changed.
Jonathan arrived with tea through an ordinary door and found a second one standing a few feet inside. He walked around it.
“I’ll leave you to decide which you prefer.”
By the following afternoon, they had stopped trying to reproduce the memory exactly. Daniel began to understand that the Avari had created what suited their work. The Six needed a place that suited theirs.
That helped more than hours of practice.
They built around the observatory table, leaving room for those who would be watching. As their understanding grew, the environment became stable enough for someone outside the Six to lean against its rail without Daniel having to think about keeping it there.
Sal allowed them to sustain it far longer than Daniel would have believed possible. Fatigue returned when they separated and attempted to work alone; together, the boy’s presence eased the physical strain before it became exhaustion. Elena insisted on meals and sleep anyway. Nobody found a useful argument against her.
Once the environment could hold, Khan met them within it.
Daniel had expected answers. He had not expected to become part of the process by which those answers were reached.
Kane questioned a repeated correction in the targeting sequence. Mara wanted to know what would happen if a keeper withdrew permission during firing. Vale followed several possible outcomes and found one Khan’s calculations had treated as too unlikely to retain.
Khan returned to it.
Its willingness to reconsider unsettled Daniel almost as much as its need to do so. He had imagined an intelligence beyond human error. Now he understood why it had been made to listen to people who could disagree.
The questions continued outside the connection. Isobel checked what Khan supplied against observations she could obtain herself, and refused to dismiss discrepancies. She and Ernesto worked late into the evenings, leaving anything they could not verify marked as uncertain.
As repairs progressed, the proposed action became clearer. A sustained beam would heat a selected region of the object’s surface, ejecting material whose recoil would alter its motion. The array would follow the asteroid’s rotation, maintaining the thrust long enough to carry it clear of Earth.
They would not need to break it apart.
Daniel returned to that whenever he considered what they were preparing to authorise. The object would continue through space, and the world beneath it would go on living.
On their final evening of preparation, he went outside and found himself missing home with an intensity he had not felt since leaving it.
Mara joined him by the low wall. The mountains had disappeared into the dark, while the observatory windows showed people still working.
“I keep thinking about my mother asking whether I’ve eaten,” he said.
“She’d have liked Elena.”
“They’d organise us between them.”
“They still might.”
Through a window, he could see Jonathan and Isobel bent over a sheet of paper. A few weeks earlier, Jonathan would have been delighted to find an observatory full of people willing to answer his questions. Now he seemed more concerned with whether one particular person had remembered to eat.
Daniel smiled.
“What?” Mara asked.
“I want that.”
“Jonathan becoming a nuisance?”
“People being difficult about ordinary things.”
She watched the window for a while.
“So do I.”
They stayed outside until the cold became uncomfortable, then returned to the others.
The following morning, Khan confirmed that the necessary repairs were complete. It was the fourth morning since Isobel’s urgent briefing, with nearly seven days remaining before the projected encounter. They would fire while there was still time for a small change in motion to become a useful distance.
Daniel was ready to agree. The thought of actually doing it was harder.
The environment formed around them with a steadiness they had never achieved before.
Daniel felt the difference immediately. The others’ presence had become part of how he understood the space. He could attend to the surface before him without losing his awareness of the distant array, or of the observatory in which their bodies stood.
Earth appeared above the shared structure. This time its continents were familiar. Cloud covered part of South America and darkness lay across the far side.
Beyond it emerged the approaching object.
Daniel knew the figures, but seeing its scale against the small blue planet gave them a meaning he had managed, until then, to avoid.
Khan showed them the proposed action once more. Sunlight gathered across collecting surfaces of almost incomprehensible reach. The energy would pass through repaired channels to the focusing array and strike a selected region of the rotating body.
Along the edge of the control surface, six recesses formed, each shaped to receive an amulet.
They had discussed permission until Daniel could imagine no further question to ask. The empty place before him made the decision personal again.
Sal had become quiet. Kane asked him to explain what he understood, and the boy described the array changing the object’s course before asking whether anything would fall on Earth.
Khan answered him as carefully as it had answered the adults.
“And if you’re frightened?” Kane asked.
“I am frightened.”
“So am I.”
Sal looked surprised. He had trusted Kane before he knew what either of them could do, and Daniel understood how easily that trust could become an answer given to please him.
Elena understood it too.
“You can say no,” she told her son.
They waited while he considered it. At last, he removed his amulet.
“I want it to miss.”
He placed it into the recess.
Daniel felt the surface accept his decision. Kane gave his own agreement and set his amulet beside it. Vale followed after a pause that seemed to contain years of choices made without knowing whether they were right.
Mara’s agreement reached Daniel with the clarity of her spoken words. Lindiwe’s came next, leaving only his place empty.
He looked at the people waiting beyond the control environment. They had no part in the authority required by the system, but they had carried the Six here, protected them, believed them and questioned them when belief was too easy.
Jonathan met his eyes.
“I agree,” Daniel said, and laid down his amulet.
The six central gems brightened, surrounded by the light of the five smaller stones in each. As the connection opened, Daniel briefly lost the sensation of his body.
The distant array became immediate. He felt energy moving through immense structures and repaired sections responding under load. The focusing system attended to a point on a body travelling towards Earth. Through the others, he retained the knowledge that they stood around a table in Chile.
The beam struck without a sound.
A region of the asteroid’s surface became white. Material rose from it in an expanding brightness, gathering into a plume as the beam concentrated. Daniel followed the turning surface and felt the array respond.
The first correction passed through them cleanly.
During the second, Kane recognised something wrong before a warning appeared. Part of the sequence was returning a fraction late, carrying a small delay forward until the next adjustment began from a position the asteroid had already left.
Khan corrected it, but the delay returned.
Daniel could feel how much of the system was operating at the edge of what the repairs had restored. The load was exposing faults that inspection alone had not revealed. As the beam’s concentration drifted, its bright region spread and the plume weakened.
“We’re losing it,” Kane said.
Daniel heard him within the connection and somewhere in the room at the same time.
Khan was drawing on an older correction sequence. It suited the array as originally built, but one repaired section now responded differently. Each attempt to recover increased the discrepancy.
Daniel tried to follow the failing sequence and the alternatives appearing beside it. Too much arrived at once. The control environment became uncertain beneath him, bringing back the memory of stone shifting above Jonathan.
He recognised the fear, but could not quiet it. The room flickered, and somewhere beyond it Elena spoke words he could not distinguish.
Mara interrupted the repeating correction before Khan sent it through again. For a moment the system stopped trying to compensate, allowing Kane to distinguish the actual delay from the adjustments built around it.
Vale followed the new possibilities. Several ended with the beam dispersing before enough change had been achieved. One remained usable, provided they could sustain a transfer Khan had rejected as too unstable.
Daniel understood why it had rejected it. He also knew what would happen if they stopped.
Through Lindiwe, he could feel the others continuing to choose. She kept their decisions distinct as fear moved between them, preventing one person’s hesitation from overwhelming the rest.
Sal was still frightened, but he remained within the connection.
His strength reached Daniel as warmth through a body he had almost forgotten. Daniel felt his breathing steady and his feet against the observatory floor. With that small certainty restored, he could attend to the part of the environment beginning to fail.
He rebuilt it to accommodate the new sequence. Khan accepted the change and began transferring the flow.
For several seconds, the plume diminished. Energy passed through a channel unused for longer than any human history, and Daniel felt the restored sections answer in turn. When one failed to respond, the flow recoiled towards its old path.
He held the new route open while Kane adjusted the timing.
The heated surface was darkening. Daniel wanted to force the system through, just as he had wanted to pull the amulet from its case. He recognised the impulse and stopped himself. They needed to work with what was there.
The channel answered.
Light gathered again on the asteroid, and the plume strengthened as the array recovered its concentration. The Six sustained the new sequence while Khan maintained the power passing through it.
Daniel no longer knew how long they had been connected. He knew they had not yet done enough.
Isobel’s calculations still showed an impact.
She had watched the new brightness develop beside the tracked point, then falter. The changing plume made observations harder to obtain, but the next positions remained usable. She entered them, checked the times and recalculated without relying on Khan’s figures.
The projected course shifted. It still crossed Earth.
She had expected a delay. A change in motion needed observations separated by enough time to distinguish it from uncertainty, but knowing that did little to help. Behind her, six people stood silent while the object they were trying to move continued towards the world.
Jonathan stayed beside her.
Before they began, he had said something about being glad someone attached her photograph to the report. She had laughed, caught between tenderness and disbelief at his timing. Now she could recall his expression exactly, and it made the line on her screen harder to accept.
She took another measurement. The course changed again, but its uncertainty still included Earth.
A brief disturbance passed through the room’s light. It steadied before she could turn to see what had happened.
“Ernesto.”
He checked the observation times while she ran a separate calculation. Their results agreed. The intervention was working, but they could not yet say it was enough.
Within the array, Daniel felt another presence.
It came as the restored connection widened: an awareness at a distance he could not judge, followed by another and others beyond it. For an instant, he recognised the sensation of the memory room, where people had occupied a place without belonging to the time in which he stood.
The impression passed through all six.
Shapes almost gathered at the edge of his awareness. There might have been a room, or faces he could not retain. He felt attention turn towards them.
Echoes, he thought. Something left by the people who had used the network before them.
Khan’s attention shifted outward. The change was so brief that Daniel might have missed it had Lindiwe not felt it too.
Then Vale brought them back to the targeting sequence. The asteroid’s rotation was carrying the selected region away, and the next adjustment needed all their concentration.
They followed it.
Rock and metal continued leaving the body in a sustained plume. Through the connection, Daniel felt the accumulating change: small against the asteroid’s mass, but no longer negligible.
Earth remained before them. He kept thinking of the horses moving through his family’s fields, oblivious to everything happening here. His mother would be busy. Somewhere in England, someone would be annoyed that a train was late.
He wanted those things to continue.
The array drew from the Sun, and the Six directed its action until Khan brought the revised course into view. The line approached Earth and passed beside it.
Daniel could not bring himself to trust the distance.
The beam made its final adjustment. Material continued streaming from the rotating object, and only when the array ceased firing did the plume begin to thin.
“The revised course clears Earth,” Khan said. “Your observations will need time to confirm it.”
Daniel looked towards Isobel. She was still working.
Before releasing the environment, each of the Six lifted their own amulet from its recess and returned it to the frame against their chest. Sal was last. Kane waited beside him until the boy had secured his, and only then did they allow the created surfaces to fade.
Sal went straight to Elena.
Daniel remained where he stood, conscious once more of his body but uncertain what to do with it. Around him, the observatory had become an ordinary room again. Isobel’s screen held the only answer he wanted, and she could not yet give it.
Over the next several hours, Isobel continued taking measurements. Ernesto checked the observation times while she tested the revised course independently of Khan’s figures. Jonathan stayed beside her, and the others rested nearby, reluctant to leave before she could tell them what she knew.
At last, she removed the most uncertain observation and ran the calculation again.
The predicted course cleared Earth.
She restored the observation. The result held.
Ernesto checked her inputs and compared them with the incoming figures. Neither spoke until another measured position widened the margin.
“Isobel,” Jonathan said quietly.
She realised she had been holding her breath.
“It’s changing.”
She needed one more observation before saying the rest.
When it arrived, she checked it against the calculation. She had spent so long looking for the mistake that would return the object to its original course that belief came reluctantly.
“It misses.”
Jonathan waited.
She turned towards the room.
“It misses Earth.”
Only then did she realise how still the others had been. Elena held Sal close. Kane had lifted his head, and Daniel watched her as though he could not quite believe he was allowed to stop waiting.
She understood. The result was there, supported by observations she had checked herself, yet she could find nothing useful to do with her hands.
Jonathan took one.
For a moment she held herself together through habit. Then his fingers closed around hers, and he stayed beside her while she cried.
The following days belonged to confirmation.
Isobel observed whenever conditions allowed and compared her results with those arriving from elsewhere. The revised course held. Other observatories recorded the plume and adjusted their predictions, arguing over whether the earlier calculations had been incomplete or the object’s behaviour had changed.
Both explanations appeared in reports. Neither accounted for what she had witnessed.
A brief anomaly recorded by Ulysses during its passage through the Sun’s southern polar environment joined the growing collection of measurements. Its significance would be debated by people who had never heard of the Six. Isobel kept a copy beside the firing time.
At La Silla, the visitors began making plans beyond the predicted encounter. That mattered to her more than their first celebration. Elena called her sister and spoke about returning. Kane promised his family a visit, then remained on the telephone while his niece described a problem at school.
Jonathan started losing things again. He asked Isobel whether she had seen his notebook while she was holding it. When she returned it without comment, he looked at her twice.
The Six discussed the other presences they had felt. Their accounts differed, but all remembered an awareness of minds beyond their own. Jonathan suggested that the restored system might retain impressions of those who had once worked through it.
After what they had experienced in the memory stones, it seemed a reasonable explanation.
Lindiwe remembered Khan’s attention turning outward. She had no answer to place beside the others’ recollections, and for now she left the question alone.
On the evening of the close approach, Isobel checked the latest positions before joining everyone outside.
The object was passing beyond Earth on the course they had made possible. It remained whole. There would be photographs and studies, years of discussion about what had almost happened.
Sal was disappointed that they could not simply look up from the terrace and see it. When she told him the observations confirmed it had passed, he considered that instead.
“Good.”
The simplicity of his answer undid her more than any speech could have.
Elena began discussing food. Ernesto said there was coffee inside, although he could not promise it was fresh. Jonathan asked whether that had ever stopped anyone here, and the conversation carried them towards the doorway.
Isobel waited for him.
“You found your notebook?”
“Yes.”
“Try to keep it.”
“I’m considering attaching it to myself.”
“Ernesto could make you something.”
He smiled. She took his hand as they went inside.
Daniel remained on the terrace with Mara.
He had expected the world to feel different after it survived. The mountains were still dark beneath the stars. A vehicle moved along the road below, its lights visible for a moment before a bend concealed them. Through the open doorway, Sal asked for something to eat and Elena told him to take off his coat first.
Daniel thought of the distant array, the reach of Khan and the strange impressions that had passed through them while they fired. There would be questions. He knew that without needing Vale to tell him.
Tonight, he was content to listen to people deciding what to have for supper.
Mara stayed beside him until he turned towards the light. They went inside together.
Far from Earth, the array returned to its watch.
Repair units continued moving across its surfaces. Within the larger system, Khan returned to the brief disturbance recorded during the firing.
It isolated the response and waited.
An answer came.
