Okoro worked the way surgeons worked — hands steady, voice low, every movement serving a function that the observer couldn't always identify but that the practitioner had calculated three steps ahead. She stood at the central display in the Signals Analysis Lab on Level Two, a space that had been commandeered from its normal function (monitoring routine wormhole traffic) and repurposed into something that didn't have an institutional name because the institution had never needed one. The lab was built for three operators. It held five. Okoro, Chen, Harrison. Two technicians from Okoro's wormhole research team who ran the equipment and spoke only when the equipment told them something worth saying.
"Node one," Okoro said. She pulled the harmonic waveform onto the display — a shimmering line of data rendered in green, the visual representation of the biological frequency holding the first wormhole in the corridor open. "Frequency: 847.3 hertz. Stable. No drift in the last four hours."
She swiped. The next waveform replaced the first.
"Node two. 831.6 hertz."
Swipe.
"Node three. 815.9 hertz."
Chen saw it before she said it. His tapping finger froze mid-stroke on the auxiliary workstation Harrison had provided — a machine with processing power that made the requisitioned unit look like a calculator. "The interval."
"15.7 hertz." Okoro pulled all eleven waveforms onto the display simultaneously. Eleven green lines, stacked vertically, each one shorter than the last by the same precise increment. "Each node's frequency is exactly 15.7 hertz lower than the previous one. Node one: 847.3. Node eleven: 690.3. A descending scale. Eleven steps. Equal intervals."
The display showed it. Eleven wormholes arranged in a line across Haven's surface, each one vibrating at a frequency slightly lower than the one before it. A musical progression written in dimensional energy and held open by biological power.
"That's not random," Harrison said from his corner of the lab. He'd been quiet for two hours — watching, processing, applying the intelligence analyst's method of observing a system until the system revealed its logic. His tablet sat open on the secondary desk. The network architecture diagrams from the classified system's firmware analysis glowed on its screen. "That's an encoding structure. A key sequence."
"It's a key," Okoro confirmed. She expanded the display. The Haven surface map appeared — the corridor of nodes rendered as eleven blue points connected by a dotted line, the path from the contact clearing to the terminus coordinates. "Each node is tuned to a specific frequency. The frequencies descend in precise mathematical intervals. If you transit through the corridor in sequence — entering at node one and passing through each subsequent node — you experience the complete frequency set. Your body, your equipment, anything passing through the corridor absorbs the full harmonic range."
"Absorbs it for what purpose?" Chen asked.
"I don't know." Okoro's admission was clean. No hedging. The professional honesty of a scientist who distinguished between what the data showed and what the data meant. "But the terminus point — the coordinates in Sergeant Tanaka's prosthetic — sits at the end of the descending sequence. The lowest frequency. 690.3 hertz. Whatever is at those coordinates, the corridor is calibrated to prepare you for arriving at it. The harmonic progression tunes the traveler."
"Tunes them to what?"
"To whatever frequency the destination operates on." She turned from the display. Looked at Chen. At Harrison. The wormhole specialist's eyes were sharp — the focus of a researcher who had spent her career studying dimensional physics and who was now confronting an application of those physics that exceeded every model she'd built. "The nodes aren't just a path. They're an instrument. They're playing a sequence that conditions anyone who walks through them. By the time you reach the terminus, you've been harmonically calibrated to interact with whatever is there."
Harrison stood. Moved to the central display. His professional distance — the auditor's buffer zone — was shrinking. The information was pulling him closer physically the way gravity pulled objects toward mass. "Commander. The biological energy holding these nodes open. The organic frequency. How much energy would this require?"
"More than any biological system I'm aware of could produce." Okoro pulled a secondary dataset onto the display — energy readings from the Haven monitoring array. The numbers were large. The units were unfamiliar to Yuki's experience but clearly significant to Okoro, whose expression tightened as she presented them. "Each node requires continuous energy output equivalent to — the nearest comparison I can offer is a small nuclear reactor. Eleven nodes. Running continuously. For over twenty-four hours. The biological organism or organisms producing this energy are operating at a scale that doesn't have a terrestrial analog."
Eleven nuclear reactors' worth of biological energy. Held stable for a day. Tuned to mathematical precision. To build a road that played a song.
Chen turned from his workstation. The gray in his face had deepened — the sleepless hours compounding, the ribs extracting their toll with each breath, the body reporting its limits while the mind refused to acknowledge them. "I have something."
He pulled his analysis onto the central display, displacing Okoro's waveforms. The screen split — left side showing the data architecture from Yuki's prosthetic, right side showing the classified network firmware that Harrison had provided.
"The Meridian firmware — the data mirroring protocol embedded in the Intelligence Division's classified network. I've been analyzing its programming structure. Not what it does — Harrison already documented that. How it does it. The code architecture. The logic patterns. The way the programmer organized the instructions."
Harrison moved closer.
"Every programmer has a style," Chen continued. "Like handwriting. The way they structure conditional statements, the way they nest functions, the way they handle exceptions and edge cases. It's a fingerprint. Unique to the individual or the training methodology that produced them." He highlighted sections on both sides of the split screen. "The Meridian firmware uses a specific pattern for data routing — a branching logic tree that distributes information through parallel channels simultaneously. It's efficient. Elegant. And unusual. The branching ratio is based on Fibonacci sequences. Not standard. Not taught in any programming curriculum I know."
"The arm data," Harrison said. Not a question. He'd seen where Chen was going.
"The biological encryption on the arm data uses the same branching pattern." Chen highlighted the comparison. The structural similarity was visible even to non-technical eyes — the patterns rhyming, the logic trees branching at the same ratios, the organizational philosophy identical despite the different mediums. "One is written in machine code for a human network. The other is written in biological encryption for organic data storage. The languages are different. The syntax is different. But the thinking is the same. The same mind designed both."
The lab was quiet. The technicians at their stations had stopped their monitoring tasks. Okoro stood at the display, her arms crossed, her sharp eyes moving between the two highlighted sections with the focus of a scientist watching a proof resolve.
"The Meridian firmware was installed eleven years ago," Harrison said. His voice was careful. Measured. The voice of an intelligence officer building a conclusion from evidence and making certain every brick was load-bearing before he added the next. "The arm data was created in 2041. Forty-four years ago. If the same intelligence designed both—"
"Then it's been operating for at least forty-four years," Chen finished. "Designing embedded systems. Programming human technology and biological systems. Writing code that hides inside infrastructure and does things the operators don't know about." He looked at Harrison. "Your network leak and my alien encryption were built by the same architect."
Harrison's tablet sat on the desk beside him. The network diagrams glowing. The fourteen months of investigation — the personnel files, the access logs, the communication intercepts, the fruitless search for a human traitor — all of it recontextualizing around a conclusion that no counterintelligence methodology was designed to reach. The mole wasn't a person. The mole wasn't even a program. The mole was a design philosophy. A way of thinking about embedded systems that predated the network it had been installed in by thirty-three years.
"One source," Harrison said. "Operating across both worlds. Embedding itself in systems — human and biological — for decades." He picked up his tablet. Held it. The device that connected him to the compromised network, the network that had been built to betray, the infrastructure that was the traitor. "The question is whether the source is human or—"
"It's not human," Okoro said.
Both men looked at her.
"The energy required to hold eleven calibrated wormhole nodes open for twenty-four hours using biological power is not human. The ability to write firmware that interfaces with both silicon-based and carbon-based systems is not human. The forty-four-year operational timeline, maintaining consistent design philosophy across decades without personnel turnover or institutional drift — that's not how human organizations operate." She uncrossed her arms. Her hands went to the display console, fingers resting on the controls with the precision of a musician at an instrument. "Whatever designed both systems is the same kind of intelligence that opened fourteen wormholes around a breeding facility on Haven and spoke Sergeant Tanaka's name in English. It understands human technology because it's been studying human technology since before the Reaper Program existed. It embedded the Meridian firmware because it wanted the classified network to leak. The leak wasn't corruption. It was architecture."
The word landed in the lab like a spent casing hitting concrete.
Architecture. Not a failure. Not a vulnerability. A design. Something had built the leak into the system the way it had built the harmonic corridor into Haven's surface — deliberately, precisely, with mathematical intention.
"Why?" Chen asked. "Why would an alien intelligence want military classified reports leaking to a corporate entity?"
"Because the corporate entity is building something on Haven that the intelligence wants exposed." Harrison's voice had found a new register — not the neutral professional tone, not the personal exhaustion. Something between them. The sound of a man whose fourteen-month investigation had just expanded from institutional corruption to interspecies conspiracy. "The leak ensures that evidence of Meridian's operations passes through channels where it can be discovered. By investigators. By IG referrals. By anyone paying attention to the data flow." He looked at Chen. At the split screen. At the matching patterns. "It wasn't sabotage. It was a signal. It was trying to get someone to look."

Webb arrived at the lab at 1847.
He came through the door the way he did everything — directly, without announcement, the physical economy of a general who had stopped performing the rituals of rank because the rituals consumed time he didn't have. His uniform was the same one from the morning's briefing. The red-rimmed eyes were deeper set. He'd been on calls — Yuki could tell by the particular tension in his jaw, the residual compression of a man who'd been translating the same crisis into institutional language for hours, to people who outranked him and didn't quite understand what they were being told.
"Joint Chiefs briefing ended twenty minutes ago," Webb said. No preamble. The operational shorthand of a commander addressing a room that was already running on his timeline. "The Haven wormhole activity has been detected by three civilian astronomical observatories. Two in North America, one in the EU. The dimensional energy signatures from the corridor nodes are visible in the standard electromagnetic spectrum to anyone running the right instruments."
Okoro's hands tightened on the console.
"Seventy-two hours," Webb continued. "That's the consensus estimate from the Joint Chiefs' communication directorate. Within seventy-two hours, the civilian observations will be correlated and published. The existence of active wormhole phenomena on an extrasolar body will be public knowledge."
"The Collective's response?" Harrison asked.
"Already drafted. Meridian Corporation's public relations division has prepared a statement characterizing the wormhole activity as 'natural dimensional phenomena under controlled scientific study.' They're positioning to frame the narrative before the civilian publications break." Webb moved to the central display. Stood in front of it. The Haven surface map with its eleven blue nodes reflecting in his eyes. "The Collective has been managing the wormhole narrative for years. They can handle civilian observatory reports. What they can't handle is civilian observatory reports appearing simultaneously with photographs of an illegal breeding facility on an alien world published by an investigative journalist with forty-eight hours of verification time."
Solberg. The journalist who was running dark on I-5, cash only, verifying sources, preparing to blow the story that Santos had launched at 0212 in Room 5-17.
"If both breaks happen in the same news cycle," Webb said, "the Collective loses control of the narrative entirely. The wormholes aren't natural phenomena — they're doorways to a world where corporations run illegal biological weapons programs. That story buries the 'controlled scientific study' angle and every piece of institutional cover that's been built over thirty years."
He turned from the display. Looked at the room. The five faces. The three professional domains — wormhole physics, signals intelligence, counterintelligence — that had been working in the same lab for six hours and had produced findings that rewrote the operational landscape.
"Tell me what you've found," he said.
Okoro went first. The corridor. The descending harmonic scale. The calibrated key. Webb listened without interrupting — his hands at his sides, his jaw set, the physical stillness of a commander absorbing tactical data and converting it into operational decisions in real time.
Chen went second. The matching design philosophy. The Fibonacci branching patterns. The single intelligence operating across both systems, both worlds, both timescales.
Harrison went third. The architecture. The deliberate leak. The possibility that forty-four years of embedded programming was a communication strategy — an intelligence trying to be heard through the channels that human institutions had built to listen.
Webb processed. The processing took eleven seconds — Yuki counted, the combat timer running in her head because counting was what her body did when it needed to stay present during moments that tried to pull her out of herself.
"You're telling me," Webb said, "that the entities on Haven have been manipulating human technology for over four decades. That they built the classified network's vulnerability deliberately. That the breeding facility's exposure — the photographs, the transmission, the journalist — is something they engineered."
"We're telling you that the evidence is consistent with that interpretation," Harrison said. The careful language. The intelligence officer's hedge that protected the conclusion without undermining it.
"Sergeant Tanaka transmitted those photographs on her own initiative."
"Yes, sir."
"And the entities created conditions where the photographs would reach a journalist through a compromised network they'd designed."
"The firmware was in place eleven years before the transmission. The architecture predates the event. But the architecture enabled the event."
Webb looked at Yuki. Direct. The red-rimmed eyes assessing something that rank and protocol and the military hierarchy couldn't quantify — the weight of a soldier who had walked into an alien clearing and come back carrying data that connected a forty-four-year conspiracy to a three-hour mission.
"The deployment," he said. Not a question. The word that meant he'd already decided and was now building the operational framework around the decision.
"Approved. Conditions." He held up fingers. Three. "Full sensor suite. Every piece of recording equipment Chen can carry. I want continuous data capture from the moment you enter the wormhole to the moment you return. Second: hard extraction timeline. Ninety minutes. You survived ninety minutes last time. That's your window. At ninety minutes and one second, you are through the wormhole and on this station regardless of what you've found. Third—"
He turned to Okoro.
"Commander Okoro deploys with the squad."
Okoro didn't react visibly. Her hands stayed on the console. Her posture didn't change. But her eyes moved — a single lateral shift, from Webb to the Haven display and back, the micro-assessment of a scientist calculating the distance between her laboratory and a forest where alien organisms built roads out of dimensional energy.
"The corridor is a harmonic instrument," Webb said. "I need someone on the ground who can read the instrument while it's being played. Commander, you have field deployment experience."
"Calibration missions," Okoro said. Her voice was steady. The professional register holding. "Standard survey deployments on Haven's southern plateau. Non-combat operational environments."
"This is a non-combat operational environment until something starts shooting." Webb's tone was the flat statement of a commander redefining parameters because the parameters needed to fit the operation rather than the other way around. "You'll be under Sergeant Tanaka's tactical command. Her squad provides security. You provide analysis. Questions?"
"No, sir."
"Deployment in two hours. 2100. Dismissed."
---
Santos had questions.
"A scientist." She was standing in the armory, running the pre-deployment check on the M7, her bruised hands moving through the weapon inspection with the mechanical fluency of repetition while her mouth ran the objection that her hands were too busy to gesture. "We're walking an alien road built out of wormholes that play music and you're adding a scientist to the squad. A person whose field experience is calibration missions on the safe side of Haven where the biggest threat is a sunburn."
"Okoro knows the wormhole physics," Yuki said. She was checking the prosthetic's diagnostic readouts — the new firmware running clean, the motor functions responsive, the four terabytes of encrypted data sitting in storage that shouldn't hold them, humming. "We need her."
"We need people who can shoot."
"We have people who can shoot." Ghost, from the bench where he was running the SR-20's barrel cleaning sequence. Quiet. The single statement dropped into the argument the way he dropped rounds into chambers — with precision and finality. "Okoro stays behind Chen. I'll cover her sector."
Santos's jaw worked. The objection grinding against the tactical logic. She looked at Ghost. Ghost didn't look up from the barrel. The disagreement resolved the way disagreements with Ghost always resolved — by Ghost saying something short and correct and returning to his weapon.
"Fine." Santos slapped the M7's charging handle forward. The mechanical slam of a woman ending an argument by starting a weapon check. "But if something with bark for skin comes at her and she freezes, I'm not losing a shot window to babysit."
"You won't have to." Okoro. In the armory doorway. She was wearing a field suit — the technical deployment uniform that wormhole researchers wore during surface operations. It was clean, unworn, the creases still visible from storage. But the boots underneath it were scuffed. Used. The boots of a woman who'd walked on Haven before, who'd stood on alien soil while instruments measured the fabric of dimensions around her, who was now standing in an armory full of soldiers and not flinching from the assessment they were giving her.
"I've deployed to Haven seventeen times," Okoro said. Her voice was the same as in the lab — steady, precise, the controlled output of a mind that organized information before releasing it. "The calibration missions weren't combat operations. But they weren't picnics. The southern plateau has atmospheric anomalies, unstable terrain, and wildlife that doesn't distinguish between a scientist and a soldier." She looked at Santos. Held the look. "I know how to move in that environment. I know how to stay out of a squad's firing lanes. And I know the harmonic data better than anyone alive. That's why I'm going."
Santos looked at her. At the scuffed boots. At the clean suit. At the woman who'd said her piece without raising her voice and without backing down.
"Stay behind Chen," Santos said. "And if I say move, you move."
"Understood."
Doc arrived. Medical kit on her back. The same heavy pack. The same clinical preparation. But she stopped at the armory entrance and looked at Yuki, and the look carried something that the clinical composure usually filtered out — the specific concern of a medic who'd just come from a patient she was worried about leaving.
"Viktor," Yuki said.
"His O2 saturation dropped to eighty-seven percent in the last hour. I've adjusted the concentrator output and added a corticosteroid boost to the dexamethasone cycle." Doc's hands checked her kit's closure straps. The mechanical motion accompanying the clinical report. "He should be monitored. I've briefed the station's medical officer. But the station's medical officer doesn't know his history and doesn't know his medication interactions and doesn't—"
"We'll be back in ninety minutes."
"I know the timeline." Doc's hands stopped. Rested on the kit's straps. "I'm telling you the timeline outside this armory. Viktor's timeline. His oxygen levels are trending in one direction, and it's not a direction that stabilizes."
Yuki nodded. No words. The acknowledgment between a soldier and a medic who both understood that some timelines ran on clocks they couldn't stop.
---
Viktor was in the corridor.
Same bench. Same position. The portable concentrator at his belt, the nasal cannula, the audible breathing that was louder than the last time Yuki had seen him — the sound of lungs working harder for less return, the biological machinery wearing past its tolerances.
He stood when he saw her. Faster this time. Not because he was stronger — because he was urgent. The body overriding its limits for the same reason soldiers override theirs: because the mission demanded it.
"Before you go," he said. "Sit."
She sat. The bench held them both. The corridor was empty. The pre-deployment period — the ninety minutes between Webb's authorization and the wormhole activation — had drawn the station's attention toward the staging area, leaving the residential corridors vacant.
"Schwarzkopf," Viktor said. The name was a key that opened a door he'd been keeping closed. "In 2081. When he detected the biological harmonics. When he collapsed the node and classified the readings and told us to forget."
"You told me."
"I told you what he did. I did not tell you what he built." Viktor's bloodshot eyes were fixed on a point in the middle distance — the corridor wall, the conduit lines, the institutional architecture that carried information and secrets with equal indifference. "After the contact. After the classification. Schwarzkopf was afraid. Not of the harmonics — of the implications. He believed that the biological signal represented an intelligence. An awareness. Something that had noticed us opening doors into its space. And he believed that the intelligence would eventually open doors of its own."
"He was right."
"Da. He was right. And because he was right, he prepared. He built a facility. On Haven. Not through official channels — through black budget allocations that he routed through intermediary programs. A research archive. A storage site. Everything he recorded during the 2081 contact — the harmonic data, the spectral analysis, his personal notes, the mathematical models he built to predict future contact patterns — he stored it in that facility."
"Where?"
Viktor looked at her. The bloodshot eyes leaving the middle distance and finding her face with the direct, unblinking contact of a man delivering information that he'd held for decades and that burned on the way out.
"The coordinates," he said. "The ones in your arm. The destination at the end of the corridor of nodes. The place the entities are building a road to." He coughed. The concentrator hissed. His hand gripped the bench's edge. "Schwarzkopf built his archive at those exact coordinates. On Haven. In the forest. Forty years ago."
The corridor hummed. The station's environmental systems cycling air through ducts. The sound covered nothing.
"Meridian built on top of it," Yuki said. The connection assembling itself — puzzle pieces clicking, the operational picture expanding from data points into architecture. "The breeding facility. They built it at the same location."
"Da. When the Collective established the Meridian operation on Haven, they chose that site. Schwarzkopf's archive was already there — buried, sealed, classified so deeply that the Collective's project managers may not have known it existed. Or they did know. And they built their facility on top of it deliberately." Viktor's grip on the bench tightened. The veins on the back of his hand stood visible against the pale skin. "The entities are not leading you to an alien site. They are leading you to an intersection. Human research and alien intelligence, at the same coordinates, layered on top of each other. Whatever Schwarzkopf buried in 2081 and whatever Meridian built on top of it and whatever the entities want you to find — it is all in the same place."
The same coordinates. Schwarzkopf's archive from 2081. Meridian's breeding facility. The entities' destination. Three layers of secrets stacked at a single point on an alien world — human, corporate, and alien, decades apart, all converging at the end of a harmonic road.
"Why are you telling me now?" Yuki asked. "You've known since the coordinates appeared in the data."
"Because I wanted to be certain." Viktor's breathing steadied. The concentrator compensated. "Chen's timestamp — 2041. Schwarzkopf built the archive in 2081. The arm data predates the archive by forty years. Whatever was at those coordinates in 2041 was there before Schwarzkopf. Before Meridian. Before any human set foot on Haven's surface." He released the bench. His hands went to his knees. The posture of an old soldier delivering his last briefing before someone else carried the mission forward. "Schwarzkopf didn't choose the location. The location chose him. The same way it chose Meridian. The same way it chose you."
Yuki stood. The bench released her weight. The corridor stretched in both directions — toward the staging area where her squad was assembling, toward the residential quarters where Viktor would return to his concentrator and his medication and his shrinking timeline.
"Tell Doc," she said. "Everything you told me. She needs the full picture if—"
"If I am not here when you return." Viktor smiled. Brief. The expression breaking through the illness the way light broke through cloud cover — sudden, warm, gone. "I will tell her. Go. The door is open. Walk through it with your eyes functioning."
She walked. Behind her, Viktor sat back down on the bench. The concentrator hissed. The corridor held them both for another three seconds — the old soldier and the squad leader, connected by a mission that had started forty years before either of them had arrived and that was now pulling them toward a point where every thread converged.
---
The staging area was loud.
Not with voices — with machinery. The wormhole ring was cycling. The superconducting magnets climbing toward operational temperature, the electromagnetic containment field building between the ring's inner surface and the dimensional membrane it was about to tear open. The sound was a rising hum — felt more than heard, a vibration that started in the floor and climbed through boot soles and leg bones and into the chest cavity, the physical announcement that physics was about to be violated in a controlled and repeatable manner.
Yuki's squad was on the platform. Ghost at the front. Santos behind him. Chen beside Okoro — the technician and the scientist shoulder to shoulder, his signal analyzer active, her tablet displaying real-time harmonic data from the Haven monitoring array. Doc behind them. Six people this time. The number that changed the tactical geometry — five soldiers plus one specialist, the formation adjusted to accommodate a body that didn't carry a weapon and that the other five would protect while it did something more important than shooting.
"Transit harmonic is anomalous." Chen's voice. The analyzer in his hand, the screen showing waveform data. His gray face had found a register below gray — something bloodless, the complexion of a man running on processing power instead of physiology. "The standard wormhole frequency is shifting. The transit corridor is adopting a harmonic profile that—" He stopped. Checked the screen. His tapping finger went still.
"That what?" Yuki asked.
"That matches node one in the corridor. 847.3 hertz. The wormhole is tuning itself to the first step in the sequence."
Okoro's hands moved on her tablet. Fast. The data flowing. "Confirmed. The transit harmonic has shifted from the standard calibration frequency to match the corridor's entry point. The wormhole isn't just opening a door to Haven. It's synchronizing with the corridor."
"Meaning what?" Santos asked. The M7 in her hands. The forward lean already established. The combat posture that was Santos's default state and that she wore the way other people wore concern.
"Meaning the corridor is pulling the wormhole into its sequence," Okoro said. "We won't arrive at a random insertion point. We'll arrive at node one. The beginning of the path. The first note in the scale." She looked up from the tablet. At Yuki. At the squad. The scientist's face carried something that the professional composure wasn't designed to hold — the expression of a researcher who had spent her career studying wormholes as mathematical phenomena and was now about to step through one that was playing music. "When we transit, the harmonic will mark us. Calibrate us. By the time we reach the other side, we'll already be part of the sequence."
The wormhole ring reached operational temperature. The shimmer appeared — the dimensional boundary between CENTCOM and Haven, the membrane that separated one world from another. But the shimmer was different. The standard wormhole shimmer was silver. Neutral. The color of bent light.
This one was amber.
The color of Haven's filtered light. The color of the entities' eyes. The warm, organic tone of a biological system expressing itself through physics that should have been mechanical and that was, instead, alive.
"Control, this is Specter Lead." Yuki keyed her comms. The tactical channel. The last communication before the transit. "Squad is deployment ready. Six personnel. Hard extraction at ninety minutes. Confirm."
"Confirmed, Specter Lead." The control booth operator. Professional. Steady. But Yuki heard the undertone — the controlled discomfort of a technician watching a wormhole change color and pretending the color didn't mean anything. "Transit window is active. Harmonic profile is non-standard. All monitoring systems recording."
Yuki looked at her squad. Ghost, already in the transit stance — weight forward, rifle up, the posture that said he'd be shooting before his feet found ground. Santos beside him, the M7's barrel catching amber light from the shimmer. Chen and Okoro, their instruments running, their screens showing data that described the key they were about to enter. Doc at the rear, medical kit secured, clinical eyes steady.
She looked at the amber shimmer. At the wormhole that had changed its color to match the world it led to. At the door that had been opened not by human physics but by something biological, something old, something that had been waiting at the end of a harmonic corridor since before the people walking through it had been born.
"Move," she said.
Ghost stepped through first. The amber shimmer took him — swallowed his silhouette, dissolved his outline, pulled him through the dimensional membrane with a sound that was not the standard transit hiss but something lower, rounder, a tone that hummed in the same register as the vibration in Yuki's prosthetic arm.
Santos followed. Then Chen and Okoro together. Then Doc.
Yuki stepped to the shimmer's edge. The amber light played across her face. Warm. The prosthetic hummed against her side — louder now, resonant, the firmware in her arm harmonizing with the wormhole's frequency the way a tuning fork harmonized with the note it was built to match.
She stepped through.
The transit was not four seconds.
