The tips of her shoes appear one after the other beneath her lowered gaze. The dry sound of soles striking stone. The crystalline light of the September sun. Water breaking rhythmically against the hulls of boats.

She leaves through the gate of the Ex-Cotonificio, morning classes finished, noon approaching. She turns right, crosses the small bridge over the Rio de le Terese, gives a generous glance to the façade of San Nicolò dei Mendicoli, and walks east at a quick pace. Just past the corner, a sudden gust throws the intense smell of drying laundry into her face. From the open windows come the sharp sounds of plates and pans and mysterious people beginning to stir for lunch. Her gaze remains fixed on the pattern of the fondamenta pavement: an intricate web of humble anthracite-grey stones covering the lagoon city like the plates of a gigantic ancient carapace.

Venice is extraordinary. Large enough to intimidate anyone, small enough to learn all its shortcuts quickly. A labyrinth in which to get lost. A nonsense capable of swallowing you inside tourist hordes or lowering you into profound silence.

Fondamenta Fusina. Barbarigo. Briati. Ponte Foscarini. Very few tourists here. At most, the ones who get lost. She moves quickly among locals and fellow students. The Carmini is already in sight. Her black leather shoulder bag bounces against her hip with the rhythm of her vigorous, confident stride.

She crosses the campo diagonally, then takes the final left turn toward Campo Santa Margherita.

Late September is enchanting in Venice. Classes at the IUAV have only just begun; there is still plenty of time before studying becomes demanding. A comfortable interval before the cold, foggy autumn arrives. Sun. Blue sky. The right temperature, punctuated by short, sharp sea breezes. Leaves preparing to turn yellow.

The morning passes in a flash. She is hungry, needs to stretch her legs, and wants a good slice of pizza. Student lunch on a budget, yes, but satisfying.

Noon sharp. As she walks, she reviews the appointments ahead and tries to remember everything she has to do.

“What is on my agenda today? Is there nothing this afternoon?”

“Why can I not remember anything?”

“What a curious amnesia. It must be the hunger.”

Distracted by the question, she does not notice she has already entered the campo.

Santa Margherita is buzzing. A bazaar of improvisation, energy, and daily repetition. Students. Lyceum pupils. Cadets. People on benches beneath the plane trees, gathered at the edges of the campo or sitting at small tables in the sun. Over everything floats the sharp, invasive, persistent smell of the fish market closing for the day. Fishermen wash their polystyrene crates beneath the fountain, leaving a few ice cubes trapped in the drain grid. The rush of water covers their clumsy, singsong muttering.

A line of red benches stands beneath the crowns of the plane trees. Her favourite is the first, nearest the fountain. Its once-vermilion paint is peeling, revealing wood greyed by sun and time. She loves it because it sits directly opposite the bookshop.

Beside the shop: Pizza Al Taglio. Then the red bar. Then the shop with brooms, buckets, and cleaning products, breathing the smell of Marseille soap into the campo.

The day is perfect for a generous slice of pizza and a cold Coca-Cola, strictly from a can and strictly through a straw.

Across the campo, a restaurant extends beneath a large striped awning. From the upper windows, slender rods reach into the void, each with a fragment of mirror attached to its end. Three handsome plane trees stand in the middle of the square, proudly demonstrating that something natural still survives inside this entirely artificial city. At the far end rises the truncated campanile opening the calle toward San Pantalon. Geraniums in windows. Seagulls the Venetians call cocai. The distorted calls of boat sirens crossing the canal.

She sits for a moment on the red bench. Sparrows land timidly at her feet, searching for something to put into their beaks. They always arrive before the lazy pigeons, which prefer to walk. One sparrow has a ruffled wing and feathers permanently askew.

From the bench, she can enjoy the bookshop. She has been there countless times, yet she cannot remember its name.

“What is it called?”

Nothing comes.

A man passes with a handcart piled with packages, all held together beneath a generous layer of cling film. Before lunch, she decides to look inside. She always makes a quick round of the shelves. It is one of her habits.

She performs an elegant slalom through the books displayed beneath the outside awning and enters decisively. Those shelves are for tourists. The section she wants is at the back. Architecture.

The shop is a long, narrow rectangle divided into two rooms by a full-height shelf. Modest white metal shelving stands beneath exposed wooden beams, lit by economical fluorescent tubes. There is not much choice. Nevertheless, the shop maintains a reasonably current collection of El Croquis, and she loves El Croquis. It is an irrational pleasure entirely her own. She leafs through the monographs without shame, enjoying even the smell of the paper and the glossy smoothness of the covers. She is greedy for images, plans, sections, and details. For the brief possession of a design contained between precious pages.

Her right index finger travels along the spines.

“What luck!”

El Croquis no. 88/89, Mundos / Worlds (I). One of her favourites. It costs too much, but as long as she can survive on pizza and Coca-Cola, she can afford it. The moment the monograph is in her hands, she tears away the cellophane. A visceral pleasure.

She leaves the shop with the treasure beneath one arm and goes directly to the pizza place to accomplish her first and non-negotiable mission. Food.

She joins the queue and breathes in the smell of pizzas emerging from the wood-fired oven. There is no menu. They make whatever they make, cut it into slices, and sell it immediately. Today she is lucky. A spicy salami pizza has just come out. She takes a slice at once.

“Careful not to burn your fingers.”

The pizzaiolo behind the counter passes it over on a simple sheet of waxed paper. No plates here. She steps back into the campo, satisfied, both hands occupied and the monograph tucked beneath her arm.

The red bench is still free. The sun remains strong. A few small clouds soften the brightness from time to time. It is lunchtime.

She settles into her frugal lunch and looks north. The truncated campanile. Strange. She has always wondered whether it was cut deliberately or merely abandoned unfinished. Beyond it, the Ponte di San Pantalon. Past the bridge, the church of the same name with its picturesque unfinished brick façade. Behind her, the fishermen wash their polystyrene crates beneath the fountain. A few ice cubes remain trapped in the drain.

Wait.

“Are those the same ones she saw before?”

“Déjà vu?”

“Is that possible?”

She holds the slice carefully by the crust, the point of the triangle aimed toward her mouth. The Coca-Cola can rests on the ground. The smell of warm bread restores her. Mozzarella steams. The small circles of salami are roasted perfectly, almost crisp at the edges. Her mouth waters.

The first vibration of the bell reaches her.

Everything stops. People become sculpture. Birds hang in the sky. The fountain freezes in the act of falling.

Complete silence.

She has no time to look around.

White. Nothing. Then black again.

The dry sound of soles striking stone.

At the end of everything, where the universe runs out of reasons to continue, there is a structure.

ANTAM is the last black hole. The final gravitational event. The point beyond which even time has stopped arguing. Around it, orbiting at a distance that can be measured but that the mind refuses to hold, hangs a station so thin it resembles a line more than an object. Anthracite lattice entwined with golden filament. Long eyelashes extending into the dark: millions of narrow threads reaching toward the event horizon and passing beyond clear physical perception.

NOVARK. The line around ANTAM.

From its body descend the filaments called DUATs. They touch, almost touch, or pretend to touch the membrane below, which things stop being the kinds of things that can be explained.

Inside NOVARK is a place devoted to looking down at the only thing that does not look back, because it does not need to. Everything that has ever been is there already.

A drone stands at the Eye. Anthracite geometry. Precise. Still. His back is turned to the chamber as he faces the membrane’s edge, the point where NOVARK ends and the event horizon begins. The threshold has a name. LIMEN. Its law is absolute: fifty-one percent or more means irreversible deletion. Immediate. No authorization required. No interruption possible. No return.

He extends one arm. His hand passes through Limen and disappears on the other side. The arm ends at the wrist. He remains there.

Do not look for too long. Eyelashes around an eye that never closes. The absence where the hand should be.

“I wish I could feel it.”

A small, precise BEEP. In any other context, negligible.

A point of light appears inside the anthracite lattice of his forearm. Not gold. Not any frequency he has logged before. A tiny pink light spreading from a single point the way warmth spreads from a puncture. Or a bite.

He withdraws his arm. The hand reappears. He studies the fading pink point, then turns away from the Eye.

The Observatory empties.

Below it, the event horizon. Around it, NOVARK’s long eyelashes move like lines cast simultaneously by countless fishermen, never touching one another.

Black. Only black. Not the black of an ending, but the beginning of something whose name has not yet been given. The kind of black that becomes other colours when you wait.

Grey. Granular. Stone.

The particular anthracite of Venetian flagstone, worn by centuries of salt water and feet. The pattern of a city built upon what should not hold a city but does.

What should not exist but does, because existence is sometimes less a question of logic than of the stubbornness of matter.

Black becomes stone.

The tips of her shoes appear one after the other beneath her lowered gaze. The dry sound of soles striking stone. The crystalline light of the September sun. Water breaking rhythmically against the hulls of boats.

She leaves through the gate of the Ex-Cotonificio, turns right, crosses the bridge over the Rio de le Terese, and walks east. Laundry in the wind. Plates and pans behind open windows. The anthracite pattern of the fondamenta beneath her feet.

Fondamenta Fusina. Barbarigo. Briati. Ponte Foscarini. Very few tourists. At most, the ones who get lost, which serves them right.

She crosses the Carmini and takes the final left turn into Campo Santa Margherita. Noon sharp. She reviews her appointments.

“What is on my agenda?”

“Nothing this afternoon?”

“Why can I not remember?”

The campo opens around her before she notices she has entered it. Near the fish market, the ruffled-wing sparrow searches the paving stones for some crumb, some warmth, some small and specific mercy the world apparently owes it. She does not notice the bird.

She buys a slice of pizza, takes it to the red bench, and sits in the sun. The sparrow hops closer without invitation. She breaks off a corner of crust without thinking.

The September light lies flat across the stones. Everything is quiet enough to be beautiful. She eats without hurrying and watches the campo conduct its slow, particular business.

A woman in an old, ugly trench coat walks near the fish market. Grey hair. She stops at the fountain and looks down at the melting ice cubes in the gutter.

For one brief moment, barely a breath, the world misses a step. One frame dropped. One beat withheld. Between one instant and the next, a gap opens that has no name and closes before she can look directly at it.

The campo is the campo again. The light is the light. The sparrow works its beak against the crust.

Strange, how the mind plays tricks when you are tired. Or when September is being too beautiful for comfort.

She reaches for another bite and dismisses the moment the way one dismisses the suspicion of having been here before.

Biri sits before his loom. It is not a loom in any sense a human would recognize, but the word applies as well as any: twelve threads of gold light stretched taut across a dark console, responsive to his attention the way fibre responds to practised fingers.

Twelve threads. Always twelve. Always gold. Always precisely themselves.

Until now.

A thirteenth appears between the seventh and the eighth without warning or ceremony. A colour for which he has no name. Not gold. Not silver. Not any frequency he has been trained to read. Something between colours. Something that should not be a colour and is.

His fingers close around it.

The loom disappears.

A structure rises inside his mind. Enormous. Red-orange cables. A surface below, moving in waves so broad he cannot see the other edge. Two hands gripping a railing, the fingers of one almost touching the other. Then one hand. The other is gone.

Biri tears himself away as though struck by an electrical current. The loom returns. One shoulder hits the wall. His palms press flat against the dark material. Warm. Palms in NOVARK do not become warm.

He remains there for many etaticks without counting them, listening to the twelve gold threads hum at their familiar frequencies. The thirteenth hums something else. Numbers and ciphers gather around it, all unfamiliar.

“What are you?”

She is at the gate of the Ex-Cotonificio with the bag on her shoulder and the stones beneath her feet. She turns right. Crosses the bridge. Walks east. The smell. The sounds. The stones. Everything exactly where she left it, though she does not remember leaving.

She arrives in the campo at noon. The sparrow is already at the fountain. The red bench waits empty.

She approaches the drain. Five ice cubes sit wedged in the grid. She does not count them upon entering. She knows there are five before she looks. The counting only confirms what she already knows: the wrong order for things to happen in.

The sparrow hops onto the edge of the bench.

“You again.”

It regards her with the patience of something that has been waiting for recognition and is not surprised to receive it.

The bell begins to toll. One toll. Harder this time.

Now she sees it.

The sparrows freeze mid-motion. The light flickers, oversaturates, and returns. Several seconds are missing from the afternoon without asking anyone’s permission.

She remains very still long after the campo resumes. When she moves, she does so carefully, as though uncertain the floor remains where it was.

Seto has occupied the long white corridor for so many cycles that the Brickcells have given up arguing otherwise. Two walls of shelving run parallel toward infinity. Countless folders, dossiers, and archives arranged with meticulous, almost manic precision. At the centre stands a white marble desk. Cold. Inevitable. Heavy. An altar more than a desk.

Seto sits behind it on a modest stool, completing records and registers. Biri stands before her. She is still a drone, but the hierarchy between them is beyond dispute.

“It is not a malfunction.”

Seto does not look surprised.

“Log it as a malfunction.”

“It has structure. The internal architecture of a self-referential signal. A malfunction cannot produce that.”

Her old, heavy face rises from the open file.

“Log it as a malfunction, Biri.”

He does not know how to be dishonest. No one has ever given him the opportunity to learn.

“It is not a malfunction, Seto.”

She leaves the file open and straightens with the authority of someone who has had this conversation before. An ice-cold pause.

“Log. It. As. A. Malfunction.”

Biri does. His hands do not feel right afterward. He leaves without another word.

Seto waits until his steps disappear. Then she turns her head slightly toward the darkness beyond the altar.

“What do you want me to do?”

A voice emerges from deep inside the corridor.

Let him run it. We might use it.

She is approaching the campo. She does not remember arriving.

Just before entering the campo, she finds the same tourists standing at the same intersection with the same map. She approaches them.

“Excuse me. Are you lost? Can I help?”

They look through her. Not past her. Through her, the way people fail to register pigeons at their feet.

A man approaches with a handcart.

“Watch the cart, young lady!”

He does not stop. She exists only as a fixed obstacle in his path.

She returns to the red bench and begins to test the world. Right on cue, a pigeon lands exactly where she knows it will. Not roughly. The exact same place.

“Okay.”

The bookshop next. She was here yesterday. She bought the monograph. El Croquis 88/89. She proceeds to the shelf. She finds the copy. Her copy. Inside the cellophane. She takes it from the shelf and places it on the counter. She looks at the cashier very seriously.

“I bought this yesterday. Do you remember?”

The cashier is heavyset, his hair caught in a thin, tired perm. He gives a short, surprised laugh.

“Listen, sweetheart. If you want the magazine, you pay for it.”

She looks at him the way one looks at a madman, leaves the book on the counter, and walks out.

The pizzeria. A slice of salami pizza. A Coca-Cola with a straw.

“Yesterday I ordered exactly this. You told me not to burn my fingers. Do you remember?”

The pizzaiolo laughs loudly. Embarrassment and amusement pass across his face.

“What are you talking about, lady?”

The silence spreads outward. Someone at the back of the queue loses patience.

“This woman is out of her mind. Move on. I’m hungry.”

The square swallows her again.

“What is happening to me?”

The red bench waits empty. The fishermen wash the polystyrene crates beneath the fountain. She approaches with fear growing inside her.

“Please. Not five.”

Five ice cubes in the drain. She knows before she looks.

The bench. The plane tree. The market. The woman in the old trench coat. The sparrow landing first, as always.

“You again.”

Two more sparrows follow. She watches them with something close to dread. Not fear of the birds, but fear of knowing exactly what they will do next.

The bell tolls once.

The world freezes harder. A visible judder, like a film print skipping two frames. Sparrows suspended. Light oversaturating. September gold turning briefly impossible. Then everything returns in the wrong position. A pigeon two metres from where it stood before. Several seconds gone.

She does not flinch. This time, the freeze lasts longer.

The White. The black. The masegno. The steps. The walk.

Anka does not look up.

“You need a favour. Or someone who won’t ask why.”

Biri stops just outside her line of sight.

“Both.”

Now she looks. Her attention goes directly to his forearms. The warmth is still there, faint but persistent.

“That isn’t catch residue. Catch residue fades within a kilotick.”

“I know.”

“Does Seto know?”

“She told me to log it as a malfunction.”

A dry almost-laugh.

“That is Seto’s way of saying yes without making herself say it.”

Anka opens the full catch ledger from Needle 12-Khnum. Gold data scrolls through the dark.

“Show me the timestamps.”

“Eleven forty-one. Then eleven fifty-three.”

She enters both. The ledger redraws itself: a long flat line interrupted by two sharp spikes.

“Twelve etaticks.”

She studies the gap.

“Does it feel as though it’s getting louder?”

Biri does not answer. Beyond the edge of the chart, a third gap is already opening, waiting to be filled.

Anka takes the Tracker from the assembly shelf. A band of light approximately three centimetres wide. No screen. No visible surface. No interface beyond its behaviour: one tap to exit, two to search, three to summon the lift. She built it according to instructions. Nilo’s instructions, delivered without explanation and requiring none. The band glows in her palm at the frequency of the thirteenth thread. She places it in the receiving case and closes the lid.

“You are a master.”

Biri accepts the case with almost ceremonial reverence.

“Do not push your luck. I dislike useless flattery.”

Anka rises.

“Let’s visit our common friend. I adore the atmosphere in the Amun.”

They walk away. Workshop 7-Maat dissolves behind them like a water mirage, leaving two grey silhouettes moving through the Embedded corridor.

She is on the bench and has been there, it seems, longer than she can account for.

The ruffled-wing sparrow lands beside her without invitation. She has not torn off any crust.

“Not today.”

The bird hops onto her black leather bag and looks up indignantly.

She closes her eyes. This time she will remain conscious through the freeze. This time she will see what lies on the other side. The bell tolls once. Stops.

The world freezes, and she is ready. She does not close her eyes. She does not flinch.

Sparrows stop. Light shifts. Inside the half-second between stillness and continuation, she sees something. Not clearly. Not long enough to describe. A shimmer at the far edge of the bench. A pipe-shaped tunnel with no source. A colour without a name, neither pink nor gold nor anything she knows.

Then it is gone.

White. Black. The masegno. The steps. The walk.

“Not again.”

The corridor is unchanged. Biri and Anka walk its full length. Shelves dense with documentation accumulated across giga-cycles of NOVARK record-keeping. Two lines of luminous light run parallel beneath them, converging toward a single point in the distance, the way all long things converge, the way perspective insists upon its own logic.

Seto is already watching.

“If this concerns your malfunction, it is logged.”

“The problem is that it lasted twelve etaticks.”

She sees the readout. The pink glow, faint and stubborn. For a fraction of a moment, something other than irritation moves across her face. Recognition.

“Where did you get the interval?”

“Two spikes in 12-Khnum’s catch ledger. Eleven forty-one and eleven fifty-three. Both structured. Both filtered as noise.”

“And the second one? You didn’t merely see it.”

“No.”

A long silence. Seto places her ledger on the desk.

“Sit down. Both of you.”

Neither sits. She does not insist.

“What you are describing has a name. We do not use it casually, not because it is forbidden, but because it is inconvenient. Once a loom operator knows the name, he begins to look for it. Once he begins to look, he tends to find it.”

“I have already found it.”

“Yes. I noticed.”

She turns the readout toward herself and studies the two spikes as though looking at an old photograph.

“It is called a Koan. Officially, a Koan Interval. Yours carries a high classification. Most loom operators complete their existence without catching one. Most who do catch one wish they had not.”

“What is it?”

Seto appears to suffer the answer like a criminal forced to confess an inconvenient truth.

“A surge from the other side of the horizon. From inside ANTAM. Structured. Self-aware, in whatever sense something beyond that line can be self-aware.”

She chooses every word.

“It occurs when something inside acquires self-consciousness.”

Biri looks down at the pink light beneath his forearm.

“A conscience.”

“On its own, a Koan is only a surge. Gone before a filter can open in time to meet it. It becomes noise to us because we are never listening at the right moment.”

“Listening.”

Anka repeats the word as though testing its architecture.

“That is what happens when you listen.”

Seto looks directly at Biri.

“If the surge fires while the filter is open at precisely the same moment, the two meet. And whatever is on the other side—”

Something moves across Biri’s face. The Observatory. His arm passing through Limen. Reaching into the void. Doing nothing useful. Listening. The beep. Then the thirteenth thread at his loom, already tuned to something he cannot name, turning pink. He is lucky. In the right place, in the right state, at the right moment. Listening.

“Now you know the name. Use it to walk away. That is the only good reason to learn it.”

Seto returns the ledger to its shelf.

“Off you go.”

The conversation is over.

They walk back through the corridor. The lines of light recede behind them.

“What a lovely way to shut our mouths.”

Anka turns Seto’s unfinished sentence over inside her mind.

And whatever is on the other side...

“Can be collected.”

She stops.

“Are you serious?”

“Terribly serious, my agnostic friend.”

Behind them, Seto sits alone at the altar desk. Files. Shelves. Two strips of light, perfectly still. At the far end of the corridor, the blue-grey wall fails to hold. A darkness appears where the light leaves no reason for one.

Seto does not look at it. She lifts a luminous file and continues working.

“The situation is running out of control…”

The darkness withdraws like a tide.

Their Koan is unique. It would be a pity not to use it.

The corridor is empty again.

You know what to do.

Seto approaches the shelves of empty folders.

“Yes. I do.”

The ceiling has no limit. Gold light rises slowly through the floor. Breathing. Hundreds of drones sit cross-legged in concentric rings, each equidistant from the next, perfectly still. Light climbs from the soles of their feet to the crowns of their heads. The tradition of silence here is so old and dense that speaking means speaking into a held breath. Nobody does it.

In the outer ring, three drones mutter while trying to draw as little attention as possible.

Biri inclines by the smallest perceptible degree.

“Cables. Enormous. Red-orange. Against a flat grey surface. Far below, another surface moving like waves, so wide I couldn’t see the other side. Two hands, side by side. The fingers of one almost touching the other.”

“Not our hands?”

“No. One hand remained. The other was gone.”

“Gone where?”

“I don’t know. The image ended there.”

Ambe’s eyes open.

“You think I was programmed yesterday? I can hear you. You are not discussing a simple malfunction.”

Anka stares at the floor.

“Just draw your Brickcells.”

“What colour was it?”

Biri can no longer conceal it.

“So you know what it is, you son of a bricky gambler.”

Ambe looks almost pleased.

“A Koan?”

Biri and Anka exchange a glance. So much for secrecy.

“How do you know about Koans?”

“It is a long story, my friend.”

“Of course it is.”

Anka’s irritation barely remains beneath a whisper.

“In any case, the thread has a colour for which we have no name. When I interact with it, I receive a vision.”

“What vision?”

“A structure. Darker than the first. Red-orange cables. Enormous.”

Biri raises two fingers, sketching the shape of something suspended in immeasurable space.

“How do you know the scale? How did you measure it?”

“By comparison with the hand.”

Gold light pulses once through the Commons.

“If it fired twice within twelve etaticks—”

“Don’t.”

“I am only thinking.”

“I know what thinking looks like on you. It looks like pricing.”

Ambe does not deny it. His gaze returns to the light beneath them.

“A thing with intent, practising its passage through ANTAM’s event horizon, is the most interesting object in the universe. Possibly the only interesting object left in it.”

Anka looks at Biri.

“I want in.”

Ambe does not lower his voice further.

“Whatever this becomes when you pull it properly, I am there from the beginning. Not consulted. Not thanked. In.”

A long beat.

“Granted.”

“Four sessions of silence. I will have the interval within twenty ticks.”

He closes his eyes. To any drone looking toward the outer ring, he appears identical to the others. Lit from below. Charging. Meditating.

“The hands, Biri.”

Anka leans closer.

“You saw someone.”

He nods.

“Something on the other side of the event horizon is holding that moment. It has been holding it. And it reached out.”

Gold rises through his cells, patient and endless.

“I was the only one listening.”

At the outer edge of the ring, there is a section of floor where the gold does not rise as it should. A small absence. No shape. No sound. Three beats. Gone.

Ambe never gambles without calculating first. His workstation resembles a baker’s table covered not in flour but in crumbs of incomplete luminous Brickcells. Every surface is occupied by objects of which he is fiercely, silently possessive. At the far end, the filter chamber glows peacefully. Through its crystal-clear wall, the needle extends toward ANTAM like an infinite airport bridge promising a departure that will never come.

Biri and Anka arrive. Ambe reads their faces.

“That is not a we-won-a-bet expression.”

“Eleven forty-one. Eleven fifty-three. Twelve etaticks. When does the next one fire?”

He studies the readout. Something shifts behind his eyes.

“Beautiful.”

He pulls the projection closer. Twelve etaticks. Then twelve again.

“If the interval isn’t flat. If it narrows even slightly—”

He works in silence. Anka and Biri wait.

“Eleven decaticks. Forty ticks.”

The three of them look at one another. This is the line.

“I will open the filter when it fires.”

Ambe’s confidence falters.

“That is not a we operation. If Seto finds out—”

“She already knows the interval.”

“She made no decision about it.”

Biri’s smile is grim.

“She also said nothing about not absorbing it.”

Ambe stares at him.

“Then I truly am the son of a bricky gambler.”

He begins recalibrating.

“For the record, this is going to be a magnificent bet. There may be a great many Brickcells in it.”

“Then it is fortunate that you are good at bets.”

Biri is already moving.

She is already on the left side of the bench. Every constant is in place. The sparrows. The empty half.

“Okay. I’m here.”

The September light holds. The plane tree holds. The campo holds its breath.

“I’m not leaving this time.”

Barely audible.

A sparrow passes beneath the bench. Her gaze follows it, carrying her attention toward the campanile mozzato. At its base is a small wooden door she has never noticed before. Beside the door, a terracotta pot filled with geraniums. The pot is always fully illuminated by the sun. She knows this. It belongs to her mental inventory. Now half of it lies in shadow.

She rises and studies the campanile. Its shadow falls across the campo at a different angle. Only a few degrees, but different from where it has remained frozen through every previous repetition.

Nothing else reacts. Nothing should be able to.

She sits again on the left side of the bench. This time, she does not watch the sparrows. She watches the empty half.

Something has shifted in the architecture of the place. Not in the stones. Not in the light. In the rule holding them together. A crack. Only wide enough to be seen.

“Something is about to happen.”

She waits.

The countdown passes three etaticks. Ambe’s hands move rapidly, holding the filter open against something pushing back.

She sits on the bench without checking anything. Her attention remains fixed on the empty half with the concentration of someone who finally understands what she is waiting for.

“Thirty ticks.”

The air shifts. Barely perceptible. The change that passes through a large building when a distant door opens. A slight alteration in temperature. The September light changes by a degree without a name.

“Ten ticks.”

The bench is no longer empty.

The countdown reaches zero.

For a fraction of a second, nothing happens.

Then a violent pink flash fills the chamber. Everyone in the Confluence shields their eyes. The frequency collected from ANTAM passes through the surrounding Brickcells like an earthquake wave. An impossible silence descends.

At the centre of the filter chamber, a surge forms. Pink. Bright. Growing. The colour fills the room with a warmth that has no business existing here. The warmth of something that crosses the event horizon and does not stop.

Light catches. Hangs. Twists. Folds into itself.

A shape begins to form. Shoulders. The suggestion of a head. A woman’s silhouette held between ANTAM and NOVARK, between the interior of a black hole and the last station at the end of the universe. Neither arriving nor leaving. Trying.

“There.”

A woman sits on the right side of the bench. The side that has remained empty in every loop, without exception.

Older. Perhaps in her fifties. Silver hair catches the September light and holds it. An ugly old trench coat belongs to neither this season nor, perhaps, any season. She occupies the bench with the ease of someone sitting in a place she knows intimately. Settled. Unhurried. Entirely at home.

She looks across the campo, quietly admiring the angle of the light, the old stones, the plane trees, the fountain. She raises one hand against the sun.

The sparrows arrive at her feet. All of them. Especially one.

“Oh. Yes. I remember you.”

She extends her empty right hand and bends toward the ruffled-wing bird. Without ceremony, without food, it begins to peck at her fingers as though she has fed it a thousand times.

The young woman approaches, astonishment and fear slowing every step. Silver hair turns toward her.

“I have always loved feeding the sparrows.”

“Hold it.”

Biri takes control of the DUAT with the concentration of a captain steering through violent water. Anka disappears inside her calculations. Ambe remains the only one who appears relaxed. Or reckless.

The silhouette grows sharper inside the chamber. Warm light illuminates the entire DUAT, a colour none of the three drones has seen in all their cycles.

The young woman opens her mouth to ask the only question that matters. A question beginning in certainty and already destined not to reach its end.

“How did you kn—”
