The briefing room smelled like disinfectant and fear. Valoris recognized that particular combination from first year; the academy's way of warning students that what came next would be unpleasant enough to require extensive medical monitoring.

  Instructor Wolff stood at the front, her expression carrying a clinical detachment that came from delivering this briefing dozens of times and dozens more in the future, regardless of how students responded. Behind her, a holographic display showed anatomical diagrams of human respiratory systems overlaid with fluid dynamics equations that made Valoris's stomach tighten.

  "Liquid breathing," Wolff said without preamble. "Also known as liquid ventilation or total liquid ventilation when performed properly. You've read the orientation materials. You've seen the statistics. Today you'll experience it."

  She pulled up a new diagram showing a pilot in a cockpit, surrounded by technical annotations.

  "Why liquid immersion matters: mechs generate extreme g-forces during combat maneuvers. Ten, fifteen, sometimes twenty g's during rapid directional changes. Without liquid support, those forces would liquefy your organs and cause fatal hemorrhaging. The perfluorocarbon provides uniform pressure distribution across your entire body surface, internal and external. It prevents crushing."

  Another diagram appeared, an impact simulation, a mech being slammed into terrain.

  "Second reason: impact absorption. When your mech hits a wall at combat speed, the liquid cushions the deceleration. Without it, the sudden stop would snap your spine, rupture your aorta and turn your brain into paste against the inside of your skull. With it, you survive impacts that would kill any conventional pilot." The diagrams disappeared. Wolff's expression remained neutral.

  Around the briefing room, forty second-year students sat in rigid attention. Chimera Squad occupied their usual positions with Valoris in the center, Zee to her right radiating tension, Saren to her left with perfect posture that somehow made her look even more anxious, Quinn three seats over with their tablet displaying respiratory physiology notes, Milo further back looking vaguely ill.

  Squad Drake-29 sat across the aisle, another mid-tier squad that Valoris knew primarily through shared academic sessions and occasional training rotations. Their leader (Jasper, she thought his first name was) had that particular combination of confidence and anxiety that suggested he'd researched liquid breathing extensively and found nothing reassuring. His squadmate kept touching her throat unconsciously. Their specialist looked ready to bolt.

  "The purpose of this exercise," Wolff continued, pulling up a new diagram, "is twofold. First: physiological assessment. We need to know whether your bodies can tolerate extended liquid immersion and whether your respiratory systems can handle perfluorocarbon exchange. Second: psychological evaluation. Some candidates experience such profound panic during liquid breathing that they're deemed unsuitable for procedures requiring immersion, which is important to know before you attempt to summon and pilot a mech."

  She paused, surveying them with a look that suggested she was already calculating who would panic.

  "You will be breathing perfluorocarbon; specifically, a medical-grade compound designed to dissolve oxygen at levels higher than air. The liquid is denser than air, heavier, more viscous. Your lungs will have to work significantly harder to move it. The sensation will be profoundly unpleasant. You will feel like you're drowning. Your body will tell you that you're dying. You are not dying. The physiology works. Trust the process."

  Valoris felt Zee shift beside her. On her other side, Saren's breathing had gone very controlled, the kind of controlled that meant she was already managing panic before the actual trial began.

  "The procedure," Wolff continued, gesturing to a new hologram showing a reinforced pod, "involves full submersion in a sealed chamber. You'll be restrained – arms, legs, torso, head – to prevent reflexive flailing that could cause injury to yourself. Monitoring equipment will track your vitals, oxygen saturation, CO? levels, and psychological markers. Medical staff will monitor you constantly. If your readings indicate distress beyond acceptable parameters, you'll be extracted immediately."

  She pulled up statistics.

  "Historical data: eighty-seven percent of candidates complete the trial successfully. Nine percent experience manageable distress but require early extraction. Four percent experience severe psychological distress requiring immediate intervention and are removed from certain training tracks. Less than one percent experience physiological complications."

  Less than one percent, Valoris thought. That's still someone. That's still a real possibility of catastrophic failure.

  "Duration: ten minutes. That's enough time to establish that your respiratory system can maintain adequate gas exchange through liquid medium and that your psychological state remains stable under extreme stress. Ten minutes of breathing liquid. Ten minutes of trusting the process despite every instinct screaming that you're suffocating."

  Wolff's expression softened slightly, the closest thing to sympathy she'd probably show.

  "This will be one of the most difficult things you've experienced at the academy. More difficult than combat simulations, more difficult than advanced meditation, possibly more difficult than dimensional exposure when you eventually face it. The human body is not designed to breathe liquid. Every biological instinct will fight against it. Your success depends on overriding those instincts through conscious effort and trust in the monitoring systems."

  She gestured toward the door.

  "The facility is adjacent. You'll proceed in groups of ten, two squads simultaneously. Squad Chimera and Squad Drake-29, you're first rotation. Report to the preparation area immediately. Everyone else, remain here for additional briefing on what to expect based on observation of the initial group."

  Valoris stood with her squad, feeling that familiar pre-combat tension settle into her shoulders. Except this wasn't combat. This was voluntary submission to something that would feel like drowning while trusting that the academy wouldn't actually let them die.

  "This is insane," Milo muttered as they filed out. "Voluntary drowning. That's what this is. We're volunteering to drown."

  "We're not drowning," Saren said, though her voice carried less conviction than her words. "The perfluorocarbon provides adequate oxygen. The physiology is sound. This is a psychological challenge, not actual danger."

  "Tell that to my amygdala when liquid is flooding my lungs."

  "Your amygdala doesn't make rational decisions," Quinn observed. "That's the point. We override instinct with conscious control. That's what pilots do."

  They entered the preparation area, a clinical space that looked more like a medical facility than training grounds. Ten reinforced pods stood in two rows of five, facing each other across the room like opposing forces. Each pod was transparent reinforced material, approximately seven feet tall and four feet in diameter, with visible restraint systems and monitoring equipment built into the structure.

  Medical staff moved between the pods with practiced efficiency, checking systems, preparing equipment, marking off final safety protocols. One of them, an older woman with port scars visible at her neck, approached Chimera with a tablet.

  "You've read the consent forms?" she asked without preamble.

  "Yes," Valoris said for all of them.

  "Understand the risks? Understand that you can request extraction at any time but that early extraction may affect your training track eligibility?"

  "Yes."

  "Any history of panic disorders, claustrophobia, respiratory issues, cardiac abnormalities, or psychological conditions that might complicate the procedure?"

  They each answered in turn, all negative, all cleared through the extensive medical screening that preceded second year.

  The medic nodded. "Strip down to academy-issue undergarments. Remove all jewelry, accessories, anything that could interfere with monitoring equipment or cause injury during restraint. Proceed to your assigned pod. Once inside, the restraint system will activate automatically. Do not resist restraint. Resisting causes injury and disqualifies you from the trial."

  Valoris moved toward the changing area with her squad, stripping down with the clinical efficiency they'd learned over eighteen months of academy life. Around them, Squad Drake-29 did the same, Jasper moving with false confidence, his second visibly shaking, their other three members displaying varying degrees of controlled terror.

  The undergarments were minimal, designed for medical monitoring rather than modesty. Valoris felt exposed, vulnerable, as the medics marked her with her academy ID number under the right collarbone in temporary ink that would wash away. Beside her, Zee looked like a coiled spring, all that combat-trained muscle now serving no purpose except maintaining composure. Saren's precision had become rigidity, every line of her body screaming controlled panic. Quinn looked detached, probably already mentally reciting respiratory physiology to distract from the immediate reality. Milo kept adjusting his glasses even though he'd already removed them.

  "Pod assignments," the medic called out, reading from her tablet. "Cadet Kade, Pod Three. Cadet Zavaretti, Pod Seven. Cadet Maddox, Pod Four. Cadet Sterling, Pod Two. Cadet Renn, Pod Nine. Drake-29 squad, opposite row. Move to your pods now."

  Valoris approached Pod Three in the middle of the row, directly facing one of Squad Drake-29's members across the room. The pod stood open, interior visible, restraint systems waiting like patient predators.

  Inside: A padded chair, reclined at approximately forty-five degrees. Restraints for wrists, ankles, thighs, chest, and head, all padded but unmistakably secure. Monitoring sensors studded throughout the interior. At the base, visible inflow ports where the perfluorocarbon would enter. At the top, atmospheric venting that would seal once the pod filled.

  She climbed in, settling into the chair with careful control that suggested if she moved too quickly she might bolt instead. The padding was cold against her skin. The pod smelled of disinfectant and plastic.

  "Remain still," a medic said, approaching her pod. "Restraint activation in ten seconds."

  Valoris forced her breathing steady. Four counts in. Hold for seven. Eight counts out. The meditation pattern, the thing that had gotten her through first year's worst moments, the technique that supposedly helped maintain coherence during dimensional contact.

  The restraints activated with mechanical precision. Wrists first, padded cuffs closing around her arms, gentle but completely secure. Then ankles, then thighs, then a wide band across her chest that limited her breathing range even before the liquid arrived. Finally, the head restraint, a cushioned support that locked her skull in place, preventing any movement that might cause injury or allow her to thrash.

  She was completely immobilized. Couldn't move her arms, couldn't move her legs, couldn't turn her head, could barely expand her chest enough to breathe deeply. Vulnerable. Trapped. At the mercy of systems and staff she had to trust absolutely.

  Across the room, she could see Zee in Pod Seven through the transparent walls. Zee's eyes were wide, her breathing too fast, that combat readiness having nowhere to go now that she was restrained. To Valoris's right, if she rolled her eyes, she could see Saren, jaw clenched so tight it had to hurt.

  "Final systems check," a medic's voice came through speakers in her pod. "Confirm you can hear me."

  "Yes," Valoris said, voice steadier than she felt.

  "Perfluorocarbon inflow begins in thirty seconds. The liquid will enter from ports at your feet and rise gradually. Keep breathing normally. As the liquid rises past your face, you will need to consciously inhale liquid instead of air. Your body will resist this. Override that resistance. Take a breath. The liquid provides oxygen. Trust the process."

  Thirty seconds. Half a minute until voluntary drowning.

  "All pods ready," another voice announced over the facility's main speakers. "Inflow sequence initiating. All subjects: maintain normal breathing. Monitor your vitals displays if it helps you stay calm. Medical staff are watching constantly. You are safe."

  Valoris looked at the small display visible in her peripheral vision; heart rate elevated but stable, oxygen saturation normal, CO? levels normal, blood pressure slightly high. All green. All acceptable. All meaningless once the liquid started rising.

  The inflow began with a soft hiss. She felt it before she saw it, cold liquid pooling at her feet, rising with steady mechanical precision. The temperature was wrong. Not quite body temperature, maybe a few degrees cooler, enough to be noticeable. The sensation of it climbing her legs made her want to jerk away, but the restraints held firm.

  Four counts in. Hold for seven. Eight counts out.

  The liquid reached her thighs. Her hips. Her stomach. Rising inexorably, patient, uncaring about her autonomic terror. Her chest tightened despite the breathing exercises.

  Across from her, Squad Drake-29's member – she couldn't remember which one, couldn't focus enough to identify them – was hyperventilating, their vitals display flashing yellow warning indicators. Medical staff approached their pod but didn't extract them yet. Giving them time to adapt. Giving them a chance to override the panic.

  The perfluorocarbon reached Valoris's chest. She could feel the weight of it now, the density pressing against her ribcage, making each breath require more effort. The liquid was climbing her collarbones. Her neck. Her chin.

  This is fine. This is survivable. The physiology works. Trust the process.

  The liquid reached her mouth. Her lips sealed reflexively. The perfluorocarbon continued rising past her nose, past her eyes, over her forehead. The pod was filling completely. The world took on that strange underwater quality, sounds muffled, light refracting, everything distant.

  The atmospheric venting sealed with a soft click that she felt more than heard.

  She was completely submerged. Completely restrained. In a sealed pod filled with liquid that was supposed to provide oxygen but felt like drowning.

  Her lungs burned. She'd been holding her breath since the liquid passed her mouth, instinct overriding conscious thought. But her chest was screaming for air, her body demanding oxygen, her autonomic systems insisting that she was suffocating.

  The vitals display in her peripheral vision showed her oxygen saturation dropping. Slowly, but measurably. She needed to breathe.

  Breathe. Just breathe. Override the instinct. Inhale.

  She tried. Her throat closed immediately, gag reflex engaging, every biological system screaming that this was wrong, that liquid in her lungs meant death, that she needed air not this dense chemical drowning.

  Her oxygen saturation dropped further. Her heart rate spiked, display flashing yellow. She tried again, forced her throat open, forced herself to inhale liquid.

  It poured into her lungs like cold concrete. Dense, heavy, wrong. Her body convulsed despite the restraints, trying to cough it out, trying to expel the foreign substance. But there was no air to breathe, no alternative, just more liquid and the choice between inhaling it or suffocating.

  She inhaled again. And again. Each breath was work, each cycle of moving liquid in and out of her lungs requiring effort that breathing air never did. But her oxygen saturation stabilized. Held. Then slowly climbed back toward normal ranges.

  It works. The physiology works. I'm breathing liquid and not dying.

  The sensation was profoundly unpleasant. The weight of the liquid in her lungs, the effort required to move it, the wrongness that penetrated everything despite the PFC being completely inert. Her chest ached with the work of ventilation. Each breath felt like pushing through resistance, like breathing against weight.

  But she wasn't dying. Her vitals were stable. She was breathing liquid and surviving.

  She forced herself to look through the transparent pod wall toward her squad. Zee was thrashing, or trying to, the restraints preventing actual movement but her body clearly fighting the experience. Her vitals display showed flashing yellow across multiple markers, medical staff hovering near her pod. But they hadn't extracted her yet. She must still be within acceptable distress parameters.

  Saren sat rigid, not moving at all. Quinn's vitals showed they were meditating despite the liquid breathing, their consciousness retreating to that analytical space they occupied during stress. Their pod was utterly still, their body achieving stillness even in extremity.

  She couldn't see Milo from her position, but she could see his vitals on the shared display medical staff monitored. Elevated heart rate, oxygen saturation borderline acceptable, CO? climbing slightly. Distressed but functional.

  Across the room, Squad Drake-29's member – Amara, Valoris identified her now – was panicking badly. Her vitals were red across the board, her body visibly convulsing despite restraints, her oxygen saturation dropping despite the liquid providing adequate oxygen. Her nervous system was rejecting the experience so completely that her physiology was failing to cooperate.

  "Extraction protocol, pod eight," a medic announced over speakers. Amara's pod began draining immediately, the perfluorocarbon flowing out, replaced by air. Amara gasped and coughed and vomited liquid as soon as her mouth cleared the fluid level.

  Valoris forced herself to look away, to focus on her own breathing, on the effort of moving liquid in and out of her lungs.

  Ten minutes. Just ten minutes. Count them. Mark time. Stay conscious.

  Time dilated underwater. Seconds felt like minutes, minutes felt like hours. The effort of breathing never lessened, each cycle requiring conscious attention, a forced rejection of the panic that wanted to surface and overwhelm her.

  Her chest ached. Her diaphragm screamed. The liquid felt heavier with each breath, as though her lungs were slowly filling with concrete rather than perfluorocarbon. But her vitals stayed stable. Green across the board.

  Zee's vitals improved slightly; she was still yellow on heart rate, but her breathing had found rhythm, the initial thrashing subsiding into trembling stillness. She was adapting. Fighting through the panic.

  Eight minutes elapsed. Then nine.

  Valoris's consciousness had narrowed to the mechanics of breathing. In, pushing against resistance. Out, working to expel the dense liquid. In. Out. In. Out. Each cycle an act of will, each breath a conscious rejection of the instinct screaming that she was drowning.

  One more minute. Sixty seconds. You can do anything for sixty seconds.

  "Ten minutes elapsed," a medic announced. "Extraction sequence initiating for all remaining subjects."

  The perfluorocarbon began draining from the pods with mechanical efficiency. Valoris felt the level drop past her forehead, past her eyes, past her nose. She gasped when it cleared her mouth.

  The transition was worse than the submersion. Her lungs were full of perfluorocarbon, heavy and aching, and her diaphragm was trying to expel it while simultaneously inhaling air. She coughed, violent, wracking coughs that brought up liquid in thick streams. More coughing. More liquid. Her chest burned, her throat raw, her sinuses flooding with perfluorocarbon that refused to drain properly.

  The pod finished draining. The restraints released with mechanical clicks. Valoris stumbled forward, still coughing, PFC streaming from her nose and mouth in heavy rivulets that didn't absorb into anything, just ran in slick streams down her chest and pooled at her feet. A medic caught her, supporting her weight, guiding her toward a medical station.

  "Normal reaction," the medic said calmly, pressing what looked like a thick rubber squeegee against Valoris's arm, wiping away PFC in long strokes that left her skin glistening but not wet. "The perfluorocarbon drains passively but it takes time. Keep coughing. Get it out. Here–"

  She pressed a basin into Valoris's hands just in time for her to vomit a horrifying amount of liquid that looked like water but felt like death. The PFC poured out thick and heavy, more volume than seemed possible, her lungs seemingly endless in their capacity to hold the liquid substance.

  Around the facility, the other candidates were experiencing similar reactions. Zee was coughing so hard she could barely stand, supported by medical staff, her face flushed and her eyes streaming. PFC ran in sheets down her body, plastering her hair flat, the liquid beading and flowing rather than soaking. Saren sat on a bench looking perfectly composed except for the steady stream of perfluorocarbon running from her nose and the violent trembling in her hands that betrayed how much that composure cost. Quinn stood alone, methodically coughing, each expulsion precise and controlled, PFC pooling around their feet. Milo had collapsed entirely, curled on his side while a medic monitored him, his breathing shallow and pained as he coughed liquid.

  "Keep coughing," Valoris's medic instructed, one hand on her back tracking her respiratory pattern. "We need at least eighty percent cleared before you can move to decontamination. Breathe between coughs… yes, like that. Again."

  Valoris obeyed, her body finding a rhythm – cough, breathe, cough, breathe – each expulsion bringing up more PFC that seemed impossible given how much she'd already expelled. The medic used the squeegee-towel to wipe her face, her neck, anywhere PFC continued to stream.

  "Ninety seconds," the medic announced, checking her tablet. "Respiratory clearance at seventy-three percent. Keep going."

  Two more minutes of violent coughing. Three. Valoris's chest felt bruised from the inside, her throat scraped raw. But finally the liquid stopped coming up in such volume, just occasional smaller amounts mixed with saliva, her lungs beginning to function normally again.

  "Acceptable clearance," the medic said, marking something on her tablet. "Decontamination shower, bay three. Strip completely, specialized soap dispenser is the green button. Regular water won't cut it, you need the surfactant. Thorough rinse, especially your hair. Post-immersion care station is through the far door. Move when you're ready. Take your time."

  Valoris nodded, still coughing intermittently, and moved toward the decontamination area. The floor was slick with PFC; pools of it everywhere, the liquid refusing to absorb into the rubberized flooring, just beading and flowing in mercury-like streams. She passed Zee being guided by a different medic, still coughing but functional. Saren had already moved ahead toward the showers. Quinn was receiving respiratory therapy, something about persistent fluid in their lower airways. Milo was still at the medical station, medics using what looked like suction equipment to help clear his lungs.

  The decontamination bay was all white tile and drainage grates, multiple shower stalls separated by frosted panels. Valoris entered bay three, stripped off her soaked academy undergarments, dropped them in the designated receptacle. Her skin felt slick but not wet, coated with something that wanted to bead away but had nowhere to go.

  She pressed the green button. Translucent gel dispensed into her palm; surfactant soap, the medic had said. It felt slightly oily, nothing like normal soap. She spread it over her arms, her torso, working it into her skin. The gel seemed to grab the PFC, making it slough away in thick streams when she rinsed. Regular water alone would have left her coated. The PFC was too hydrophobic, too unwilling to mix. But the surfactant broke something at a molecular level, letting the perfluorocarbon finally release.

  She washed three times. Then a fourth because her hair still felt heavy, still held PFC in the strands that wouldn't drain normally. The surfactant soap turned her hair into something closer to normal wetness, finally letting the trapped liquid flow away.

  By the time she finished, her skin felt oversensitized, scrubbed clean but raw, the chemical assault leaving everything tender. She dried with the provided towel and wrapped herself in the clinical robe hanging on the wall.

  The post-immersion care station was through the far door, a medical space with treatment chairs, supply cabinets, and several medics moving between students who'd finished decontamination.

  "Sit," a medic instructed, gesturing to an empty chair. Valoris obeyed, still coughing occasionally, her lungs protesting the transition from liquid to air. “Robe off.” The medic retrieved supplies from a nearby cabinet while Valoris obeyed. "You survived your first liquid breathing session," she said.

  "Yes."

  "Lungs feel like hell, skin feels scaly, throat is raw, sinuses are flooding?"

  "Yes."

  "Normal reaction." The medic dispensed a generous amount of white cream into Valoris's palm. "Medical-grade moisturizer. Everywhere: face, neck, arms, legs, torso. PFC disrupts your skin barrier even though it's inert. If you don't moisturize, you'll get contact dermatitis."

  Valoris spread the cream over her arms while the medic continued preparing.

  "Your lungs just spent ten minutes doing something they weren't designed for," the medic continued, pulling up Valoris's post-extraction respiratory data on her tablet. "You're going to cough intermittently for the next hour, possibly the next few hours. Small amounts of residual PFC will come up; that's normal, nothing to worry about. If you cough up anything with blood, report to Medical immediately. If breathing becomes difficult rather than uncomfortable, report immediately."

  She handed Valoris a small breathing device, a tube with a resistance valve.

  "Respiratory exercises. Three sets of ten breaths, once per hour for the next six hours. Helps clear any remaining deep lung fluid and prevents inflammation from settling. Like this–" She demonstrated, breathing through the device with obvious effort.

  Valoris tried. The resistance made her chest ache, but she completed three breaths before another coughing fit interrupted.

  "Good enough for now. You'll get better at it. Your body is still transitioning." The medic marked something on her tablet. "Any unusual symptoms? Vision problems, hearing changes, headache, chest pain beyond expected soreness, numbness, tingling?"

  "No."

  "Ears feel full? Pressure in your sinuses?"

  "Yes," Valoris admitted. "Like they're still full of liquid."

  "They probably are. PFC drains slowly from enclosed spaces. You may need manual irrigation if it doesn't clear in the next few hours. Come back if pressure doesn't resolve. We can flush it. It’s not pleasant but it’s effective."

  The medic handed her another small container. "Saline rinse for your sinuses. Use it before bed tonight and tomorrow morning. Helps clear residual PFC and reduces inflammation."

  Valoris accepted the supplies, still applying moisturizer with her other hand. Around the care station, her squad was at various stages of the same process. Zee sat in the next chair over, being checked for sinus issues; the medic was examining her ears with a light, asking about pain, dizziness, hearing changes. Saren was already dressed in a fresh academy uniform, still coughing intermittently, her hands shaking slightly as she accepted her own supplies. Quinn stood at a respiratory therapy station, using a more complex breathing device under medical supervision. Milo hadn't emerged from decontamination yet.

  "You're cleared," Valoris's medic said, checking the final readings. "Get dressed, return to your barracks, rest. No strenuous activity for the next twelve hours. PT’s been rescheduled accordingly for tomorrow. Debriefing is in–" she checked her tablet "--two hours. If you experience any unusual symptoms before then, contact Medical immediately. Questions?"

  "How long until breathing feels normal again?"

  "Define normal. You'll stop actively noticing the discomfort in six to eight hours. Your lungs will be fully recovered in seventy-two hours. Some pilots develop chronic bronchial inflammation from repeated immersion but you're years away from that being a concern."

  She marked something final on her tablet. "Your clearance is logged. Trial completion confirmed. You passed. Well done."

  Valoris moved to the changing area, retrieving a clean academy uniform from the provided supply. Her skin still felt oversensitized, slightly dry despite the moisturizer, the chemical assault having changed something at a surface level. She dressed slowly, each movement requiring attention because her body felt strange, disconnected.

  She still coughed intermittently, bringing up small amounts of PFC mixed with phlegm, her lungs slowly clearing the last remnants. A faint soapy smell lingered from the surfactant.

  Her squad gathered gradually in the care station waiting area. They looked like survivors of a disaster; wet hair, bruised throats, trembling hands, eyes still streaming from sinus flooding. Zee looked exhausted, her usual alertness replaced by bone-deep fatigue. Saren maintained composure but her hands still trembled. Quinn appeared distant, probably processing the experience with analytical detachment. Milo finally emerged from decontamination pale and shaking, moving carefully like his body might betray him.

  "That was the worst thing I've ever experienced," Zee said, voice raw. "I thought I was dying. The entire time, I genuinely thought I was dying. My body was screaming that I was drowning and I couldn't make it stop."

  "But you adapted," Valoris said, her own voice rougher than usual. "I saw your vitals stabilizing."

  "After four minutes of panic that nearly got me extracted." Zee coughed, bringing up a small amount of PFC, spitting it into a provided receptacle. "And now I feel like my lungs are broken and my ears are still full of liquid. I don’t know how they expect us to do this as a regular thing."

  "Training," Saren said, though her voice carried less conviction than usual. "Conditioning. Eventually the body adapts to what the mind knows is safe. That's how all pilot modifications work. We override instinct with knowledge."

  "Did you panic?" Milo asked Saren directly. "Even once?"

  "The entire time," Saren admitted quietly. "Every second. I just didn't let it show. I maintained breathing control through conscious override. But yes, I was terrified. I'm still terrified. My body is still insisting that what just happened was a near death experience."

  Quinn spoke up, their voice distant. "Unpleasant but interesting. The sensation of breathing liquid, the mechanics of gas exchange through denser medium. Worth studying. Worth experiencing to understand the physiological parameters we'll be operating under."

  "You're calling drowning in perfluorocarbon 'interesting'?" Zee said flatly.

  "Objectively, it was extremely interesting. Subjectively, it was one of the most uncomfortable experiences of my life. Both things can be true."

  "What about you?" Milo turned to Valoris. "Scale of one to ten, how much did you panic?"

  Valoris considered. "Seven? Maybe eight? The first breath of liquid was genuinely one of the worst moments of my life. It really felt like dying. But then the physiology worked and the panic became manageable. Background terror rather than acute crisis."

  "Background terror," Zee repeated. "That's the bar now? Reduced to background terror?"

  "That's always been the bar. Everything we do at the academy exists somewhere on the terror spectrum. This just made it more obvious."

  They moved together toward the exit, medical staff already preparing the facility for the next rotation.

  "Chimera Squad," Valoris said as they walked. "Zero failures. That's something."

  "That's everything," Zee corrected, still coughing intermittently. "We survived voluntary drowning without losing anyone. Even if our lungs feel like they're full of glass."

  "Do your ears feel full?" Milo asked. "Like there's still liquid in them? Because mine do and the medic said I might need them irrigated and I really don't want to find out what that means."

  "Everyone's ears feel full," Saren said. "PFC drains slowly from enclosed spaces. Give it a few hours. Use the saline rinse. It'll clear."

  They reached the briefing room where the debriefing would occur in ninety minutes.

  "I need to lie down," Zee said. "For the next twelve hours. Maybe seventy-two."

  "Debriefing first."

  "I know." Zee coughed, bringing up another thin stream of PFC. "But I'm fantasizing about unconsciousness anyway."

  The adjacent waiting area was empty. Valoris looked at the chairs arranged in neat rows and felt her legs give out. Not dramatically. Just a slow slide down the wall until she sat on the floor, legs stretched out, head back against painted concrete.

  Her chest ached. Her throat felt scraped bloody. Her sinuses still felt full of liquid that refused to drain. But she'd completed the trial. They'd all completed it.

  Zee settled beside her without comment, shoulder pressing against Valoris's in a wordless nudge. Valoris let her head drop sideways onto Zee's shoulder. Zee didn't pull away.

  They sat like that for maybe ten seconds before Milo flopped onto their outstretched legs with theatrical surrender, glasses askew, still coughing intermittently. "If I have to move again before debriefing I'm going to die. Just leaving that information for the record."

  "Noted," Valoris managed.

  Quinn settled near them, not touching, but close enough that their presence registered as part of the group rather than separate from it. They pulled their knees up, wrapped their arms around them in self-containment, and stared at nothing while their breathing slowly normalized.

  "This is undignified," Saren said from somewhere above them.

  Valoris didn't open her eyes. "Then stand."

  A pause. The sound of Saren's controlled breathing, that particular rhythm she used to manage stress. Then the scrape of a chair being pulled closer, and Saren sat heavily in the nearest seat, close enough to be part of the configuration even while maintaining the pretense of separation.

  "Zero failures," Valoris said into the exhausted silence. "That's what matters."

  "Zero failures," Zee agreed, voice rough. "We survived voluntary drowning."

  Milo coughed wetly, shifting on their legs. "Do we get a prize for that? Besides chemical burns and permanent psychological trauma?"

  "We get to do it again," Quinn said. "Eventually. For hours instead of minutes."

  "That's not a prize."

  "That's reality."

  "Still not a prize."

  Valoris felt Zee's shoulder shake slightly in laughter or residual coughing, hard to tell which. The weight of Milo on their legs was grounding. Quinn's quiet presence registered as safety. Even Saren's proximity carried meaning, that deliberate choice to stay near them despite maintaining her careful distance.

  The debriefing could wait. Medical clearance had been logged. They had ninety minutes before anyone would care where Squad Chimera was or what they were doing. For now, they could be five exhausted second-years collapsed in a waiting area, too drained to move, too traumatized to process, existing together in shared survival.
