The alley in VY?3 is nothing but a corridor of metal and shadow, too narrow for detours, too tight for apologies.

  I pivot on instinct and flip the man over my hip. His body slams into the ground with a wet crack, dirty water exploding up the wall and spotting my pants with something that smells like rust and old oil.

  “Sorry,” I blurt.

  I mean it.

  He hears only humiliation.

  “You think that’s enough?!”

  He shoves himself up in one motion and lunges. I step aside. Not back. Not forward.

  Just… elsewhere.

  One skipped frame.

  His hand cuts through empty air, fingertips grazing the ghost of where I was.

  “Hey!”

  He tries again. Misses again. His swings turn messy, sharp with anger, his breath coming out harsher each time, echoing off the metal walls like the alley itself is amplifying his frustration.

  “Stop doing that!”

  This time, he goes for it. No half?measures. No testing. His shoulder drops, his weight commits, the kind of move you use when you want someone to stay down and feel it in their bones.

  The space shrinks around us. The sour stink of damp concrete claws at my tongue. I feel the situation slide, the thin line between accident and incident already blurring in the system’s eyes.

  “Stop.”

  The new voice cuts cleaner than any punch.

  Above us, a Skylume swivels, lens focusing. A notification flickers at the edge of my vision:

  INCIDENT FLAGGED – PUBLIC AGGRESSION

  ?0.15 CIVIC POINTS (SUBJECT: UNKNOWN MALE)

  The man freezes just long enough to see his own score dip on his bracelet.

  The new voice belongs to a med student.

  He is closer now, a little out of breath, hospital bag slung over one shoulder, white coat half?buttoned and crooked like he threw it on while running.

  “Walk away,” he says, tone calm but leaving no space. “Now.”

  The man hesitates, eyes flicking between me and the newcomer. His jaw clenches. Whatever he sees in the med student’s face makes him think twice.

  He spits a curse, shoots me one last look full of small, mean hate, then backs off and disappears toward the main street.

  Silence drops in after him, thick and oddly loud. Somewhere above, a Skyline hums past, the sound pressed flat by distance.

  The med student looks at me.

  “I know it was you,” he says.

  “…”

  “The one who saved that girl on the bus. I do not know how you did it, but… I saw.”

  My stomach folds in on itself. Heat crawls up my neck. My tongue feels too big in my mouth.

  I could lie.

  I could run.

  I do neither.

  I open my mouth, close it again. The words knot somewhere between my chest and my teeth.

  That is when the sound hits.

  Not a shout.

  Not a crash.

  Just a small, wrong noise down the alley. Too sharp, too clean to belong to dripping water or loose trash. Metal kissing water.

  My head snaps toward the darker end of the lane.

  “Did you hear that?” I ask.

  The med student frowns. “Hear what?”

  I do not answer. My body has already decided. I move, shoes splashing through shallow puddles, cold damp climbing up my socks with each step.

  I have no way of knowing that, a short walk away in the same district, someone’s hand has closed around Lix’s throat.

  Air leaves the fox’s lungs in a single, shocked cough.

  His hind legs kick once, twice, claws scraping against nothing. Tiny servos under his fur whine in protest as his internal stabilizer fights for balance that no longer exists. The man holding him does not tighten out of anger.

  He tightens with precision.

  He does not just want to remove Lix from the board.

  He wants to leave a message.

  So when he turns his back on that narrow strip of light and walks away with fox and Nullnode locked in one arm like expensive hardware, he lets something fall.

  A small, round shape slips from his fingers and drops into a stagnant puddle.

  The impact sends ripples skimming outward around an old metal token. The edges are worn smooth.

  The stamp in the center is half?erased by years of fingers and machines. It looks wrong here, like it belongs to an older version of the city no one talks about anymore, something that slipped through a crack in the update.?

  By the time I reach the end of the alley, the man and Lix are gone.

  Only the water remembers.

  I see the token first, a dull circle in the murk, catching the weak light of a distant Skylume. Beside it, half?submerged, lies something sharper, more deliberate.

  A black data key.

  The Nullnode.

  The same one Aren put in my hand and told me to keep safe. The same one Lix should never have been able to touch unless he was with me.

  My breath catches and stays there.

  For a heartbeat, everything inside me goes perfectly still. The world shrinks down to the tiny, dark rectangle half?buried in dirty water. Lix was here. With this. Which means whoever took him is close enough to drop his trail in my path on purpose.

  I drop to a crouch so fast my knees scrape stone. Cold soaks through the fabric as my fingers plunge into the puddle. The metal bites my skin as I close my hand around the key. It is heavier than it should be.

  Colder, like it has been sitting somewhere much darker than this alley.

  My jaw clenches.

  For a second, the pressure there makes no sense, a sudden ache that does not belong to the way I am breathing or grinding my teeth. It feels like the echo of something I have not done, a reaction my body is having to someone else’s pain.

  Then the rest hits.

  Pain shoots up the side of my face, bright and almost intimate, like a nerve waking up too fast. My vision trembles. The air in the alley thins into something sharp, too thin to breathe properly.

  Heat.

  Fear.

  A tiny body suspended above the ground, ribs squeezed, air burning in lungs too small, the cold taste of metal and dirty water on a tongue that is not mine but fits my mouth all the same. I should not be able to feel any of this. I know I am still kneeling in VY?3 with my hand in filthy water, and yet my chest lurches like I am hanging there too.

  A silent scream tears along my nerves, not sound, not image, just raw panic in a shape my brain translates as Lix.

  Then it is gone.

  The pain in my jaw falls back to a dull, ugly throb, like the ghost of teeth marks that never touched my skin.

  I am kneeling in VY?3 again, hand around the Nullnode, water seeping through my jeans, fingers shaking just enough that I can feel it. For a heartbeat I am not sure which body I am in.

  My heart hammers like it is trying to punch through my ribs.

  “Hey.” The med student’s voice sounds like it is coming from down a long, metal tunnel. “Hey, are you okay?”

  “My friend,” I say. The words scrape on the way out, like they have to fight through something thick and wrong in my chest. “My friend is in danger.”

  “Who?” He crouches a little, trying to catch my eyes. “Where?”

  I have nothing I can point at on a map.

  “I do not know,” I whisper.

  My fingers tighten around the Nullnode. The edges dig into my skin, small, real pain I can hold onto.

  Something flickers at the edge of my vision.

  My usual HUD tries to boot a route suggestion and then something else pushes through it.

  My HUD flashes once, then snaps into a different clarity.

  A small, pale overlay opens straight from the key in my hand, bypassing the standard system frames. It does not carry any Civic Wing branding or sound. The Nullnode is talking over the network’s voice.

  If you spot this narrative on Amazon, know that it has been stolen. Report the violation.

  VY 3 – CENTRAL PARK

  The words blink once.

  Again.

  Like a pulse.

  Like coordinates.

  Like a rendezvous.

  Central Park is only a few blocks from here. Everyone in VY?3 knows it; if you need somewhere the system pretends is neutral ground, that is where you go.

  I stare at the overlay, chest still heaving.

  “Okay,” the med student says slowly. “You are scaring me a little. Talk to me. What is happening?”

  I push myself up, water dripping from my palm. I close my fist around both the Nullnode and the old token, metal edges grinding against each other.

  “I have to go,” I say.

  “That is not an answer.”

  “I know.” I start walking. “I still have to go.”

  He hesitates for half a step, then follows.

  “Seriously? You just almost passed out in an alley, and now you are speed?walking with your fist clenched around a cursed USB drive or something?”

  “Stop following me, med creep,” I snap without looking back.

  “Med creep?” The outrage in his voice manages to sound offended and amused at the same time. “You are the one who nuked an entire bus feed and then tried to ghost through half of VY?3. I am the normal one here.”

  “Nothing about this is normal.”

  “Exactly,” he says. “That is why you need someone not currently glitching through reality to walk next to you.”

  We fall into an uneasy pace side by side, our shoulders almost but not quite brushing. The alley spits us back out onto a narrower cross?street a couple of turns from the transport hub, one of those strips the city has half?forgotten to beautify. Skylumes hang further apart here. Their light falls in uneven pools, leaving stretches of concrete in a grey that feels older than the rest of the sector. The air smells faintly of coolant and overused filters.

  My bracelet pings once, complaining quietly about route deviation. I ignore it.

  Elian’s gaze drops to my hand. I realize I am still gripping the Nullnode and the token hard enough to make my knuckles pale.

  “That thing,” he says, chin tilting toward my fist. “Is it actually a USB key or did you just decide to cosplay illegal hardware? And what is with the old coin? Retro is not really the VY?3 vibe.”

  I tighten my fingers a little without meaning to. His eyes flick to my face, catch the way my jaw locks, the way my mouth presses into a thin line.

  “Right,” he mutters. “Not just props, then.”

  “So,” the med student says after a short block, two corners and a crossing, because silence clearly is not in his skill set, “are you going to tell me your name at some point, or am I supposed to keep calling you ‘bus anomaly’ in my head?”

  “Kai,” I mutter.

  “Okay, Kai. Great. I am Elian. Now that we are not total strangers, do you want to explain why your face went white as a Skylume and then you started marching toward Central Park like it personally offended you?”I feel his eyes on my profile, trying to read every tiny twitch. My cheeks are stiff, muscles pulled too tight around words I do not have.

  “My friend,” I say again. “Lix. He is… connected to this.” I lift my fist a little, metal glinting between my fingers. Elian’s eyebrows climb when he sees how badly the token has dug into my skin. “I think someone took him.”

  “You think,” Elian repeats. “As in, you saw it happen, or as in, my mysterious data key sent me bad vibes?”

  I flinch at how close that is.

  “I felt him,” I say.

  Elian blinks behind his glasses, mouth tightening in a quick, skeptical line before it softens into something more worried. “You felt him.”

  I do not bother trying to make it sound sane. I just keep walking.

  “Cool,” Elian says after a second. “Great. Fantastic. Love that for us.”

  The street opens up faster than it should. One more turn and the buildings break just enough to let green bleed into the edges of my HUD.

  VY 3 – CENTRAL PARK glows steady at the top of my vision as we step out toward the gates.

  The closer we get, the more the air changes.

  Not cleaner.

  Not exactly.

  Just… curated.

  The harsh concrete lines soften into smoother curves. The last row of buildings breaks apart to reveal a stretch of open space in the middle of VY?3 like someone carved out a piece of sky and forced it to stay.

  Central Park is not the sprawling fantasy from old Flux clips. It is a controlled patch of green squeezed between towers and transit lines, hemmed in by railings and discreet camera poles.

  Artificial grass holds where the soil has given up. Real trees rise in careful clusters, their trunks wrapped in monitoring bands, their roots boxed in by invisible barriers. Small sensors blink at the base of each trunk, tasting moisture and air as if the system does not trust the plants to handle it alone.

  Skylumes float higher here, their light filtered through branches. The result is an imitation of dappled sunlight that almost works if you do not look too closely at the way the patterns repeat.

  Benches ring the main path, their metal edges smoothed by use. HUD ports are built into their sides, ready to project feeds for anyone who cannot stand ten minutes of unaugmented view.

  At the entrance, a low, polite display scrolls community stats.

  SECTOR VY 3 – CENTRAL PARK

  CIVIC ENGAGEMENT SCORE: 3.8

  INCIDENTS LAST 24H: 0

  Elian whistles under his breath. “Fancy. This is where you bring all your mysterious medical emergencies, or am I special?”

  I barely hear him.

  My gaze sweeps the park. Families weave between benches, joggers cut along the main path, people pretend to read while their bracelets do the real work. HUD light washes over faces, but I am only looking for one silhouette.

  Then I see him.

  Same slouched posture.

  Same oversized hoodie, hood up despite the mild air.

  Same fake bracelet, a dead band that catches the light wrong if you know what to look for.

  Aren is perched on the back of a bench instead of the seat, boots balanced on the metal rail, hands buried in his sleeves. From a distance, he could be any student killing time between transports. Up close, every part of him is a refusal.

  He is annoyingly good?looking even like that, all sharp lines and controlled stillness, like someone took a high?tier academy boy, stripped off the shine and dropped him into VY?3 just to see how much the district could scuff him.

  For a second, he does not move. His profile is turned away, watching the flow of people like he is counting exits.

  Then his head turns.

  His eyes catch on me. Recognition sharpens his face, wipes out whatever neutral expression he was rehearsing. His gaze flicks to my clenched fist, then to Elian at my shoulder.

  His mouth twists into something that is not quite a smile.

  “Seriously?” he calls out as we step off the path, his voice carrying cleanly over the park noise. “When you have a meeting now, do you always bring someone with you? First it is club kids, now you show up with a lab?rat stalker?”

  Elian blinks, taken aback. “Lab?rat? Wow. That is rich coming from someone sitting in a park with a bracelet that looks like it was printed in a basement.”

  Aren’s gaze drops, just for a second, to his hospital bag and badge. “Great. He is certified, too. That makes it so much less suspicious.”

  I do not have the energy for their voices scraping against each other.

  “I am not here for this,” I cut in.

  They both look at me.

  I step closer to Aren and open my hand.

  Metal glints in my palm: the old token, edges worn smooth, and the black key of the Nullnode, water still drying in its seams.

  "I do not know what you are playing at," I say, my voice rougher than I mean it to be, "but something happened to my companion. To Lix. He was trying to bring this to me because you wanted to see me. And now he is gone."

  The light in Aren's eyes shifts. The joke drains out of his face, leaving something sharper and older behind.

  He drops from the back of the bench and closes the distance between us. Up close, I can see the micro?scratches on his fake bracelet, the way it catches Skylume light half a beat too late.

  "You are sure?" he asks quietly. "About him. About this."

  "Yes." The word comes out before I can soften it. "I felt him. Through the Nullnode. Someone grabbed him. He dropped this. And you are the only one who pinged that key to VY 3 – Central Park."

  Elian's gaze bounces between our faces, his brows drawn tight, but for once he keeps his mouth shut.

  Aren holds out his hand.

  My fingers hesitate, then I let the token go. He does not touch the Nullnode. Not yet. He rolls the old metal disk between thumb and forefinger, tracing the half?erased stamp.

  His eyes stay on the token when he speaks.

  "If that is true," he says, voice flattening, suddenly tired in a way that has nothing to do with sleep, "then it is not me behind any of this. And your friend is really in danger."

  My throat tightens. The noise of the park, kids and distant traffic and the hum of Skylumes, drops into a muffled blur around us.

  "Then why did you want to see me?" I ask.

  Aren finally looks up from the token and meets my eyes. For a second he just studies my face, as if weighing how much to say and how much I can survive hearing.

  "Because," he says, and for the first time since I met him, there is no joke at all in his voice, "I have news about your brother."

  The word hits harder than it should.

  Brother.

  My fingers lock around the Nullnode. I feel Elian's attention sharpen at my side, the way his head tilts a fraction, trying to read the change in my expression.

  "What kind of news?" My voice sounds smaller than I want it to.

  Aren turns the token over once more, then flips it so the worn stamp faces up. The faint imprint matches something I have only ever seen on system reports and newsfeeds, not on metal in someone's hand.

  "Do you remember this?" he asks. "You should. It was on every wall in VY?1 for three days."

  He does not wait for my answer. His voice flattens, reciting from memory.

  "Incident report. Security incident at K 17 Military Drone Fabrication Center. Three Sentinel units offline."

  The line hits me like cold water. I know that report. Everyone does. It scrolled across every feed, every public screen, every cafeteria wall just last week. The system called it resolved in under forty?eight hours.

  "They said it was a calibration error," I manage. "Fixed and contained."

  "They lied," Aren replies, finally letting his gaze leave the token to pin me in place. "K 17 did not glitch. It was hit. On purpose."

  My mouth goes dry.

  "By who?" The words scrape out.

  Aren's jaw works once, like he is testing the weight of the next sentence.

  "By your brother," he says. "Not alone. He was part of a small group we still cannot fully identify. But he is tied to that file. To those three Sentinels that went offline and never came back up."

  I shake my head before I even realize I am doing it.

  "No. Paul would never—" My voice cracks on his name. "He was an athlete. A university champion. He followed every rule they gave him. He believed in the system. If there was an incident, he would never have been part of it. He does not break things, he fixes them."

  "If he had been there to contain it," Aren cuts in, not unkindly, "his name would not be buried under restricted access flags and black?file traces.

  The system does not hide people it wants to celebrate."

  I feel my face pull tight, muscles locking around denial. My chest feels too small, like someone has reached in and twisted my ribs.

  Elian looks between us, confusion and concern folding his features, eyes slightly wider, mouth pressed thin. "Hold on," he says slowly. "You are telling him his brother helped take out military Sentinels and you are doing it in a public park?"

  Aren ignores him.

  "I did not ask you here to hurt you, Kai," he says. "But if someone is using the Nullnode and leaving K?sector tokens in your path, it means whatever started at K 17 is not finished. And your brother is somewhere in the middle of it."

  My grip on the Nullnode tightens until the edges bite into my palm. For a second, all I can see is the incident line glowing at the top of a report, neat and distant:

  Now it is welded to Paul's face in my head, to his steady voice, to the way he always told me to keep my head down and trust the system.

  "I do not believe you," I manage, but it sounds weak even to my own ears. "Paul is not a terrorist. He is not an anomaly. He follows the Law."

  Aren's expression does not soften.

  "Maybe that is what he wanted you to think," he says quietly. "Or maybe he changed when the system tried to erase the wrong person one too many times. I do not know yet. I only know this: the day K 17 went dark, your brother's pattern stopped behaving like a loyal Sentinel's and started behaving like a problem."

  The word hangs between us.

  Problem.

  I feel something crack under the surface of my denial, a hairline fracture running through the image I have been holding of Paul since he left.

  Elian swallows, Adam's apple bobbing, eyes flicking from my face to Aren's. "Okay," he says under his breath, almost to himself. "So we are dealing with a kidnapped friend, a rogue data key, and a maybe?terrorist brother. That is… a lot."

  I do not answer. I cannot.

  All I can do is stand there in the too?bright park, clutching the Nullnode and an old token that suddenly feels a lot heavier, while the system's own incident report rewrites itself in my head with my brother's name scratched underneath it.
