Séhn has not moved since Mord left.Seated in the corner of cell eight, back against the angle where two walls meet—a threshold for him, even if it is not a threshold in the human sense—he listens to Louis crying through the stone.He could speak. He should speak. Another version of him would already have spoken—the version from thirteen months ago, the one that had been briefed, the one that knew exactly what to say to a subject who had just suffered a shock. A few carefully calibrated words of comfort. A cautious question to assess the subject's state. A vague promise of support that would seal the attachment even more tightly.That version of him no longer exists.It left long ago—he could not say exactly when, because his porous nature means the changes in him are always gradual, never sharp. But it is gone. What remains in its place is a twenty-three-year-old boy who no longer knows what he is supposed to do and who cries silently in the corner of his cell while his subject cries in the cell next door.He is not crying for Louis. He is crying for himself. For the boy he could have been if they had not trained him. For Miva, whom he lost. For the mother he has not seen in nine years. For the lives he has already destroyed before Louis's and that still follow him in his sleep.But above all he is crying because he knows what is going to happen tomorrow morning. He knows who Mord is going to bring. And he knows that in thirteen months he has not found the third way he asked for from an invisible threshold.•There is one thing he must do tonight. He has known it since Mord's footsteps moved away down the corridor.He must send a message.Not to Louis—Louis does not need anything more than what he has already received. Not to Narien—Narien left the fortress two months ago and Séhn does not know where she is. The message he must send is to his handler. To the woman who sent him here thirteen months earlier. To the woman who has been waiting thirteen months for him to do his job.He must tell her he will not do it.It is a simple thing to formulate. A short sentence. A few words in the code they agreed upon. Mission abandoned. Subject protected. Do not return. Three sentences. Twenty minutes to transmit them through the node system he installed in the wall of his cell, behind a loose stone the guards have never noticed.It is a simple sentence. But those twenty minutes will probably be the last twenty minutes of his life as an agent. Because the woman who sent him is not the kind of person you betray without consequences. And from the moment he sends this message, he will become a target in turn—probably for the months to come, probably for the rest of his life.He delays sending the message. Not out of cowardice—he made the decision long ago, inwardly. Out of exhaustion. The final act is heavy because it seals something that was still reversible until this moment.He looks at the wall where the loose stone is. He thinks of Miva. He thinks of what she would have said if she could see him now.•Miva was nine years old when she died.Séhn was eleven. He was the older one. He taught her useless things—songs he made up, ways of classifying clouds by their shape, the names of the birds they saw from the window of the room they shared. Miva learned quickly. Too quickly, probably. She remembered everything, and she gave it back with that stubborn precision little sisters have when they want to show they were listening.She fell ill one autumn. A nameless illness—at least one the village doctors had no name for, because the village doctors only had names for common diseases and this one was not among them. It lasted six weeks. For six weeks Séhn sang her everything he knew, and when he had exhausted his repertoire he invented new lullabies. He invented one at the end of the third week, six turning notes. She loved that one. He sang it to her twice every evening before she fell asleep.She died in the middle of the sixth week. One night. Without a sound. In her sleep. Séhn woke in the morning and saw his sister's face changed—smaller, calmer, without the agitation of sleep. He knew before he touched her. He did not cry right away. He sang the six-note lullaby one last time, very softly, because it was the only thing he knew how to do for her.His mother never recovered. For the next three years she slowly became a woman who was no longer quite there. She did not beat Séhn. She did not scold him. She looked at him without seeing him, as if every time she laid eyes on him she was searching for Miva behind him and could not find her.At fourteen he left.He left with a woman who had come to the village and noticed something in him—he did not know exactly what at the time, and he still does not know today. She had told him: You can learn things no one else can learn. Follow me. He followed because his mother no longer saw him and he had to go somewhere.It was she who taught him the Language of Thresholds. Not by teaching it like a human language—by modifying him, gently, over years, until the thresholds of the world began to answer him. When he was seventeen he could speak to any border. At nineteen he could pass through some of them. At twenty-one he had become what she wanted him to become—a man who could enter any place, win anyone's trust, and leave with whatever he had been sent to obtain.And at twenty-two she sent him into the Well, into cell eight, with a single order: Obtain from the Vermillion son the sentence his mother said to him the night they arrested her. Return as soon as you have it.Thirteen months later he is still here. He has the sentence—Louis does not know it, but Séhn heard it when the priest came down a few weeks ago and Louis finally let it slip. He has the sentence. He could leave now.He does not leave.•He finally stands up. He walks to the wall. He places his fingers on the loose stone and slides it open gently—a gesture he has perfected over thirteen months, a gesture that makes not the slightest sound.Behind the stone is a small cavity. And in the cavity is a node system—not quite the second scribe's system that transcribes the Well's conversations, an older, more discreet system that passes through other stones than those of the fortress. A system Séhn installed himself, stone by stone, speaking to the stones in a language they had not heard in a long time.He begins to transmit.The gesture consists of touching the nodes in a precise order, applying pressure in precise places, at a precise rhythm. Each combination corresponds to a word. The code is slow—it takes perhaps three minutes to transmit an entire sentence. But the code is invisible. The stones that receive it at the other end, somewhere very far away, vibrate in a way no one would notice unless they knew what to look for.He transmits:
Mission abandoned.Three minutes during which his fingers know what to do without him thinking. Three minutes during which his mind drifts toward Miva, toward the six-note lullaby, toward his sister's changed face on the morning of her death.He transmits:
Subject protected.Another three minutes. While he transmits this sentence he thinks of Louis still crying through the wall. Louis who does not know that for the last thirteen months Séhn has often sent his handler reports in which he minimized, omitted, lied. Louis who does not know that the attentions he received—the Narien stone slipped into his cheek, the invisible protections, the avoidance of certain more dangerous guards—were partly Séhn's doing, passing messages to Narien through other stones.Louis does not know. Louis may never know. And Séhn knows, as he transmits the second sentence of his abandonment message, that he will probably die before he can tell him.He transmits:
Do not return.Three more minutes. This last sentence is the most important. It tells his handler not to send a replacement to finish the job, because finishing the job would kill Louis, and Séhn does not want Louis to die even if Séhn himself does not survive.It is also the sentence that seals his fate. Because no one says do not return to the woman who sent him without paying the price.When he is finished he slides the loose stone back into place. He erases the traces around it. He returns to his corner and sits down.He waits.•He does not know how long he will have to wait for the reply. Probably not long. The woman who sent him is fast. She has means the other factions do not. She will not take more than an hour or two to receive the message, understand it, decide, and answer.He waits in the corner of his cell, back against the stone threshold. The stone beside him is warm—it has always been warm since he began leaning against it. Thresholds warm at the contact of a speaker. It is their way of greeting. Séhn has grown used to it over the years. He sometimes forgets that for normal people stones are cold.While he waits he thinks about tomorrow.Tomorrow Mord will return. With a man who claims to be called Eael Vermillion. That man will look like Louis. He will have Marielle Vermillion's eyes. He will have Arvel's jaw. He will be convincing—Mord never does things by halves, and if he chose this man it is because the man holds up.But that man will not really be Eael Vermillion.Eael Vermillion exists. Séhn knows it. His handler knows it too—it was in the briefing he received thirteen months ago. Eael Vermillion is the eldest of the siblings. He was taken at the age of five, two years before Louis was born, by a rival faction of the Order—a faction so ancient it no longer even has a name in the official registers. No one knows where he is. No one except that faction knows whether he is still alive.The man Mord is bringing tomorrow morning is probably someone Mord had prepared to resemble Eael. Real Eaels are too precious to be used as bait. But false Eaels can be found. They can be trained. They can be taught a few credible details—the cook Bellan, the proverb about the bones of kings, the color of Maela's eyes—and presented to a desperate young man who will want to believe them.Louis will want to believe. Séhn knows it. And Séhn cannot warn him clearly, because warning him clearly would trigger things he no longer controls.He can only do what he has already done—let Louis sense that there is a question without giving the answer. Let the guardian in Louis's chest do the work in his place. The guardian will not react to the presence of the false Eael—Séhn is almost certain of it, because the guardian only reacts to things that truly matter, and a false Eael does not matter. The absence of any reaction from the guardian will be the information Louis needs.It is a gamble. Séhn is betting that Louis will be attentive enough to the guardian to understand. It is all he can do for him now.•The reply arrives faster than he expected.A brief vibration in the loose stone behind the wall. Not a full message—just a confirmation vibration, the code that says message received, reply imminent. Then, after a few seconds, the real message.He begins to decode it by touching the nodes in the opposite direction. Decoding is slower than encoding because he has to translate each vibration into letters in his head.The message is short. Five words.You will die for having chosen.Séhn reads the sentence three times. No surprise—it was the expected answer. But seeing it written does not feel the same as imagining it. There is a finality in the words vibrating through the stone that imagination does not have.He closes the node system. He replaces the stone. He sits down.He thinks: Good.Then, more precisely: How long before they reach me.His handler will not send anyone into the Well—it is too public, too risky, and in any case he will soon be out of here dead or otherwise. She will wait for him to come out. She will wait for him outside. She or those she sends. Probably several teams, on several possible roads, because she does not know which direction he will take. How much time he has left will depend on luck and on the speed of what happens tomorrow morning.Probably no more than a few weeks.Perhaps a few days.Perhaps only a few hours if she has already begun to anticipate.He closes his eyes. He tries to breathe the way he was taught to breathe in moments when calm was required—through the belly, slowly, counting. He counts to ten. To twenty. He stops at twenty-three because he suddenly thinks that twenty-three is his age, and the number seems too small for a life.•Through the wall Louis has stopped crying.Séhn listens to him breathing. Louis's breathing is awake—he is doing what Séhn asked, he is not sleeping. He is waiting for morning with him.Séhn would like to speak to him one last time tonight. Not to tell him what is going to happen tomorrow—he has already done that as much as he could. Not to reveal the truth about himself—the truth is too long and he has no room to put it into words.To say thank you, perhaps.But you do not say thank you to a subject you have manipulated for thirteen months. Even if the manipulation eventually became something else. Even if you eventually came to love the subject truly. The thank you would sound false—Louis would take it as one last agent's attempt, one last little hook planted in his heart. Séhn does not want his last communication with Louis to sound like a hook.So he does what he knows how to do. He sings.Very softly, almost inaudible. To himself, one would say. But Louis will hear it through the wall—the eight and seven cells transmit the slightest sound, and Louis has learned over the months to listen to every breath that passes through the stone.He sings the six-note lullaby. The one he invented for Miva during the third week of her illness. The one he sang to Louis one night of despair, six months after his arrival in the Well.He sings the lullaby to the end. The final word—his sister's name—leaves his mouth in the silence of cell eight, and he knows it passes through the stone, reaches the other side, arrives at Louis like a gift he cannot otherwise give.Through the wall he hears Louis crying again. But differently now. Not the shock of earlier. Something calmer. Something that sounds like a farewell, even if Louis does not yet know it is a farewell.Séhn closes his eyes. He leans against the warm threshold. He waits for morning.Tomorrow Mord will come. The man who claims to be called Eael will come. There will be decisions to make, blows to strike, prices to pay. Probably a few deaths. Perhaps his own. Perhaps not—Séhn does not resign himself completely, because complete resignation would have cost too much energy at a moment when he needs it for something else.He thinks, just before sleep catches him despite himself:
If I get out of here alive, I will find a way to tell Louis everything. If I do not get out, let him think whatever he wants of me. I would rather he think me a traitor and live than owe him a truth that would slow him down.It is the last clear thought he has before slipping into a half-watch.The warm stone against his back vibrates gently, like a threshold that has received a thought and would like to answer, but cannot because thresholds do not console—they simply let things pass.He sleeps. Badly. In fits and starts. Morning will come in a few hours.
