  — The Covenant of Stars, Passage One, the Only Verse

  Scene One: The Sheikh and the Bck Notebook

  Arif Al-Nour knew that memory lied.

  Not in the sense that it invented — but in the sense that it chose. It chose what to keep and what to set aside, what to illuminate and what to shadow, and rearranged events in ways that made the past seem more logical than it had been. This was what he had studied for forty years at the university — comparative history of religions, a discipline that required its practitioner to understand how societies built their collective memory, how they chose what to sanctify and what to forget.

  But there were things even a chosen memory could not move aside.

  Like the sound of Samer Al-Zaher’s ugh.

  It was a ugh that defied description — not because it was beautiful in any particur way, but because it filled the room. When Samer ughed, every space was taken, and silence afterward had a different color. Arif had never met another human being who ughed like that — with complete absorption, as though ughter was a life decision and not a reflex.

  Arif sat in his small room in the old house in the Masjid Quarter — a quarter he had chosen twenty years ago because he loved the sound of the Fajr call to prayer, which came from four mosques at overpping times so that the voices wove into something greater than sound. He opened the bck notebook to page fifty-seven.

  A full page. All of it Samer Al-Zaher’s handwriting.

  Samer had taken the notebook from his hands twenty-three years ago in a sudden moment, during a dinner at Arif’s home — had taken it and filled it with a complete equation in twenty minutes, then returned it and said: “Keep this, Arif. Tell no one you have it. If something happens to me — you’ll know what to do.”

  “What could happen to you, Samer?”

  Samer ughed. In his room-filling way.

  Then he said, with a gravity Arif had rarely seen in him: “Many things can happen to a man who sees what should not be seen.”

  He did not continue. Arif could not make him continue that night. And three months ter, the por station exploded and Samer and Amal vanished into a pce unknown.

  Arif looked at the equation written in Samer’s hand. He had not understood it when it was given to him — he was not a mathematician. He understood it partially after years of study and questioning. And he understood it fully only when he spoke with Dr. Kai Watanabe in that secret meeting six years ago, before Kai disappeared again as was his habit.

  What he understood: the equation described a point. A specific physical point on the pnet Nadim where the pattern of the gravitational field broke. A point that Samer had called “the key” without eborating why.

  What he had not yet understood: why the number 66 appeared in every formution of the equation, no matter how the variables were changed.

  But Zaid would understand. Zaid had always seen numbers in a way no one else could. This was what Samer repeated: “Zaid sees numbers from the inside, not the outside.”

  Arif set the notebook aside. He looked from his window toward the sky. The rger sun was at its height and the smaller one trailing behind it slowly. An ordinary day from the outside.

  Nothing ordinary from within.

  ???

  Scene Two: The Memory of the Child Who Ran

  Zaid did not usually think about his memory.

  Not because he cked one — he had an exceptional memory. He retained numbers and visual details with frightening precision. But personal memory — the recollections bound to people and emotions — he treated like a sealed archive. Files that existed but were never opened during working hours or the hours of ordinary life.

  The archive had opened today.

  He sat in his room after returning from the library, the page and the book and the small notebook before him. But instead of working, he found himself thinking about the age of nine.

  Nine: the age at which parents died. Or disappeared.

  The age at which home became somewhere else.

  His uncle — his father’s brother — was a man who pictured himself as generous when he took in the orphaned child. And he believed this picture too. The problem with generosity accompanied by a daily reminder that it is generosity: it becomes a burden heavier than poverty. “You are with us like our own children, Zaid.” A sentence spoken with the tongue and stored as a debt in the air.

  In his uncle’s house Zaid learned three things early:

  First: silence cost less than speech. If you spoke, something was asked of you or something told to you that you didn’t want to hear. If you were silent, the matter ended.

  Second: numbers did not lie. People lied. Memories lied. Feelings lied. But the number 7 would still be 7 a hundred years from now and no one could change that.

  Third: escape was possible if you wanted it enough. Escape required a pn, not courage. Courage was the noise. The pn was the execution.

  At twelve he escaped. With a pn. He took what fit in a school bag — three sets of clothes and two books and the numbers notebook he had carried since he was seven — and went to the warehouse district on the outskirts of Al-Waha Al-Kubra where the small production studios operated. He offered himself to the first person he met: he would do anything.

  The first person turned him away. The second too. The third — a woman of fifty who ran a small audio studio — looked at him and said: “How old are you?” “Twelve.” “You’re lying.” “Twelve and a half.”

  She smiled. “Cleaning and reception. Eight hours a day. Five days a week. Food and a pce to sleep.”

  He said yes.

  In that studio, he saw visual effects work for the first time. Not grand effects — merely altered backgrounds for commercial advertisements. But he saw how they were made. And he saw the gaps. The pces where the light looked wrong. He told the operator beside him: “The lighting here is off.” The man stopped. Stared. “How do you know?” “I can see it.”

  Within two weeks he was correcting the effects instead of cleaning the floors.

  ???

  Scene Three: The Night of the First Hologram — The Complete Memory

  Zaid was seven when his father made the hologram.

  Not a professional hologram — it was a research instrument, a device Dr. Samer Al-Zaher used in his work. But on that particur night, in the white por station while the winds outside made a sound that sometimes resembled women singing, Samer brought out the device and set it on the low table before Zaid and said: “Shall we py?”

  His mother Amal was in the corner reviewing a research paper. She raised her head and smiled. Amal Nizar gave her smile easily, but her complete attention with difficulty — she was always in two pces at once: her body in the room, her mind in the equation. This had never troubled Zaid. He loved that her mind never settled. As though she had an inner engine that never stopped.

  “Zaid.” His father’s voice pulling him from his thoughts. “Look.”

  The hologram opened.

  It was the first time Zaid had seen a hologram up close. Not on a screen — but a real hologram filling the air before him. Six pale blue stars in distinct positions, turning slowly, as though breathing. Each star trailed a faint ribbon of light that lingered in the air for seconds before dissolving.

  He reached out to touch.

  “You won’t be able to touch them,” his father said gently. “But you can change their positions.” He took Zaid’s small finger and taught him how to move the stars through the air.

  “What is this, Father?”

  “This is our project. Mine and your mother’s. Six stars — each one in a very precise location. If its position shifts even slightly, everything changes.”

  “Like a map?”

  Amal stood suddenly from her corner and came and sat beside them. “Like a map. Exactly.” She looked at Samer with an expression Zaid didn’t understand then — something between pride and caution. “Clever, Zaid.”

  “A map of what?”

  His father said: “Of something very important. When you’re older you’ll understand.”

  The cssic line. When you’re older. Every child hated it, and ter understood that adults said it when they ran out of words — not when the truth was too complex.

  “The number 66, Zaid,” his father said after a silence. “It is the thread between everything that is real.”

  “What does that mean?”

  “It means there are things in this universe that appear separate but are bound by a thread. And whoever finds the thread finds the whole picture.”

  “And you found the thread?”

  Samer looked at Amal. She looked at him. Then he looked at Zaid and said: “We are holding its end. But the thread is long, boy. Very long.”

  Then they built the hologram together — all three of them — and Zaid recited the prime numbers like a song because that was what he did when he saw beautiful things: he transted them into numbers. And his mother ughed with her loud voice that filled the station so completely that the winds outside could not tell her voice from their own.

  That was the st happy night.

  The next day, at seven years old, Zaid sat on the floor of the station and waited for his parents to return from their boratory.

  They did not return.

  ???

  Scene Four: The Old Investigation and What Was Closed

  What Zaid knew about “the incident” came from three sources: the official report he had read when he turned eighteen, what his uncle told him in a clipped voice ced with discomfort, and what he had overheard — in passing, in conversations between people who did not know he was listening.

  The official report stated: “Explosion in the thermal reactor section of the Por Observation Station. Cause: technical failure in the coont pressure system. Victims: two — Dr. Samer Mahmoud Al-Zaher and Dr. Amal Khalid Nizar. Status: death confirmed, recovery of remains impossible due to the nature of the explosion.”

  “Death confirmed, recovery of remains impossible.”

  A phrase Zaid had read at eighteen and felt something nameless in his chest. Not grief — grief had come and gone in his childhood. Something else. Something closer to anger at an unidentifiable source: how could anyone tell a person that their parents’ bodies were “impossible to recover”? As though they were luggage lost in transit.

  What his uncle told him: “They were working on a dangerous project. I told Samer many times — this work isn’t safe. But he wouldn’t listen. Amal either. They both insisted.” The st sentence carried a muted bme aimed at the parents, not the son. But Zaid heard it as it was.

  What he overheard: once, in a café when he was sixteen, two men talking, one of them saying: “The por station — a strange case. I read a suspended journalistic investigation. The original investigator was dismissed after three days. No official expnation.” The second man said: “Cases that close like that have their reasons.” Then they saw Zaid looking at them and went quiet.

  Zaid had not searched. Or more precisely: he had tried once, at eighteen, and found a wall of closed doors and restricted archives, and decided the wall was taller than he was. That the energy spent battering it was better used building something.

  So he built.

  And the por station and what happened there became a file in the sealed archive — the archive of his choosing memory.

  Until st night.

  ???

  Scene Five: Amal Nizar — Who She Was

  That evening, Zaid opened his device and searched for his mother’s name.

  Something he had not done in many years.

  Dr. Amal Khalid Nizar. Born on Earth in the city of Tokyo to an Arab father and a Japanese engineer. She emigrated with the third wave of settlers to the pnet Nadim at twenty-three — one of the youngest astrophysicists in that wave. She had graduated with highest honors from the Tokyo Institute of Quantum Physics, then joined the University of Al-Waha Al-Kubra.

  There she met Dr. Samer Al-Zaher.

  The only photograph of her in the public archive: a group photo of a research team from twenty-five years ago. She was in the front row, second from the left. Short bck hair. The smile of someone who knew something no one else in the photograph did. Eyes looking directly at the camera with scientific sharpness and human warmth at the same time.

  Zaid looked at those eyes for a long time.

  He held the left half of them in his own face. A doctor had told him once: “Your eyes are your mother’s.” He had said nothing then. Now he thought: so when he looked in the mirror, he saw half of her.

  He searched for her research.

  Published papers since her arrival on Nadim: seven, in peer-reviewed scientific journals. Their subjects revolved around “gravitational osciltions in binary star systems” and “quantum effects on gravitational fields at critical points.” The st published paper appeared a year and a half before the explosion. Nothing after that.

  But at the bottom of her publications list, a small field automatically filled in by the database: “Registered unpublished research: 3.” Then: “Access: restricted. For viewing, contact the Scientific Records Committee.”

  Three unpublished papers.

  He did not continue the search. He closed the device.

  Not because he didn’t want to know — but because he understood that what his mother’s letter said was true: the answer was not in the archive. The archive was closed doors. The other path — the path of the puzzles — was the open one.

  And he still faced the second puzzle and whatever it concealed.

  ???

  Scene Six: Something of the Father

  Samer Al-Zaher.

  If Amal was the focused, quiet mind, Samer was the turbulent, colliding one. He thought out loud — literally, spoke as he thought and his thoughts shifted and crashed within a single sentence. He would begin with one thing and end with another, and when you said “But you said the opposite a moment ago” he would reply “I was wrong a moment ago” without hesitation.

  This honesty about error was something Zaid had loved in his father.

  In a world full of adults who never admitted mistakes, Samer was the man who said “I was wrong” with the same ease he said “I was right.”

  He taught Zaid mathematics in an unschoollike way. He never solved problems — he built them. “Make me a problem, Zaid.” At five, Zaid did not know how to construct a mathematical problem. “Give me a number.” “Seven.” “What do you like about seven?” “I don’t know. It seems lonely.” “Prime numbers are lonely, boy. That’s what sets them apart. Nothing equals them but themselves.”

  That was where it began.

  From that sentence — prime numbers are lonely — Zaid built his retionship with mathematics. Not a tool. Not a nguage. It was companionship. In the years when he was alone after his parents’ disappearance and his escape from his uncle’s house — prime numbers were present. They didn’t change. They didn’t lie. They didn’t leave.

  And he saw them as colors.

  Orange for numbers belonging to rge groups. Blue for isoted numbers. Green for numbers that formed patterns. The number 66, completed through his equations, turned a bzing orange. The color the sunset left in its final minutes before surrendering to the night.

  He had never told anyone this. He tried once at eight with his father: “Father. The number 7 is blue.” Samer looked at him with complete seriousness — he did not ugh. “How blue?” “In my head. When I see it, I see the color.” Samer was silent, then said: “This is a gift, Zaid. Take care of it.” He asked nothing more.

  This too was something Zaid had loved in his father.

  The acceptance of what he could not understand without needing to expin it.

  ???

  Scene Seven: The Moment Everything Changed — A Reconstruction

  On that night — the second night after the first puzzle — Zaid tried to reconstruct that day in its entirety.

  The day his parents vanished.

  He was seven. The morning was as ordinary as mornings in an isoted por station could be. Breakfast: toasted bread, eggs, and apple juice with that artificial taste. His mother reading a paper while she ate. His father talking to a colleague through a screen about something he understood little of. Zaid drawing numbers on a paper napkin.

  “Today you’ll stay with Supervisor Maria.” His mother speaking without raising her head from the paper. “We have a long day in the boratory.”

  “When will you be back?”

  “Before dinner.”

  “Do you promise?”

  Now she looked at him. “I promise.”

  She did not keep her promise.

  He spent the day with Supervisor Maria — a rge-framed Russian woman with a ugh that rivaled his father’s. At four o’clock he heard a distant sound. Not a rge explosion as people imagined — it was a mid-level percussion quickly followed by the ringing of arm systems. Maria took his hand and led him to the safety room at the center of the station.

  They remained there for three hours.

  When the door opened, his parents were not there.

  Not in the safety room. Not in the station’s corridors. Not in the boratory. They found no bodies and no biological trace confirming death. They found the fire. They found the burned files. And they found a back door in the boratory that had been left open.

  A back door.

  This was what had not appeared in the official report. This was what Zaid had overheard from the journalist in the café — the open back door. The detail that led the original investigator to refuse to close the case. And the detail that got him dismissed for it.

  An open door does not mean death.

  An open door means departure.

  Now — twenty years ter — Zaid sat and looked at that door in his memory as he had never looked at it before.

  His mother had written: “The explosion was not an accident. And we did not die.”

  So they were the ones who had opened the door.

  They were the ones who had walked out.

  But why? And why did they leave him? And why now — twenty years ter — were the messages beginning?

  And why in the form of puzzles, each containing the number 66?

  There was one answer he didn’t want to think: perhaps they had not been able to return before now. Perhaps there had been danger. Perhaps what they had fled was still there and they were still fighting it.

  Or perhaps — and this was the hardest possibility — they had chosen to disappear for reasons that concerned them and not him.

  This possibility would not let him sit in peace.

  ???

  Scene Eight: A Night of Water and Silence

  He went out into the alleyway at nine in the evening.

  He had no destination. He simply wanted air. The room had grown narrow with thoughts that had not stopped since the night before.

  The alleyway of the old quarter at night was a different world from its daytime self. The day filled it with movement and noise and vendors. The night left it to the sound of water in the small canal and the sound of wind between the buildings and occasionally music drifting from a distant window. He walked slowly.

  He thought about Lujain.

  He had not noticed the woman at the pavement café that morning — he had been too absorbed to pay attention. But on his way back from the library something had told him there was a presence. Not a vague feeling — his work trained him to sense human presence, to notice the details a hologram captured before the eye did. But he had chosen to ignore it because his thinking was elsewhere.

  The woman with the tied hair and the face too still with the stillness of someone watching.

  He took out his phone. Began searching in the public systems: the pte of the electric car he had seen twice in the same spot near the library. He did not finish the search. Not because he didn’t want to — but because if the surveilnce was what he suspected, tracing it from his phone might alert her.

  He stopped at the edge of the small canal. The water below moved with an indifferent sound that had no interest in people.

  He thought: if his parents were alive — and he now believed this, because his mother’s handwriting did not lie — then they needed him for something. The puzzles were not an indulgence. The puzzles were a pn. Designed by someone. Someone who knew his capabilities — knew his numerical synesthesia, knew that he memorized prime numbers, knew he was the effects genius who saw the gaps.

  Who knew all of this?

  His parents.

  Or those they had taught.

  He heard footsteps behind him. He did not turn around.

  “The night here is beautiful.” A man’s voice.

  He turned slowly.

  An old man. In his seventies. His face held a strange familiarity — as though Zaid had seen him before but could not remember where. A leather satchel on his shoulder. Eyes that carried the kind of calm that exhausted a person, because its source was not rest but a decision that had cost something.

  “Yes.” Then: “Do I know you?”

  “No.” Then: “But I knew your father.” Then: “My name is Arif Al-Nour.”

  Zaid said nothing.

  The name was spoken not as a greeting or an introduction but as the stating of a fact.

  “You were my father’s friend.”

  “I was your father’s friend. And I have known you since you were born. And I have watched you grow from a distance. And God knows I wished this day would come in circumstances lighter than these.”

  Arif walked and stood beside him at the canal and looked at the water.

  “The messages have begun.” It was not a question.

  “Last night,” said Zaid.

  “You have approximately eighteen hours before the third puzzle.”

  Zaid turned to him quickly. “You know.”

  “I know much. And this is precisely what has made my sleep heavy for twenty years.”

  A small electric car passed silently at the far end of the alleyway. Its light crossed Arif’s face for a brief moment — the face of a man weighted by what he had seen, not by what he had failed to see.

  “What do you know?” Zaid’s voice was quiet. The quiet of someone asking and knowing the answer will be rge.

  “I know why your parents disappeared. And I know why they are sending to you now. And I know what you will find at the end of the five nights if you walk to the end.”

  “Good.” A pause. “And what else?”

  Arif looked at him. “And I know that what you will find will change everything you believe you know about this pnet.”

  The water in the canal ran on.

  The wind between the buildings had its own sound.

  And Zaid Al-Zaher — twenty-eight years old, architect of illusions who believed in nothing — stood beside an old man he had not known an hour before and felt, for the first time in very many years, that there was something worth believing in.
