The footsteps reached the door before Lucia was ready for them.

  She was standing next to the observation chair with Marcus's mark in her hand. The lab was still settling, dust was in the air and she struggled to breathe. Crystal fragments ticked against the stone floor as they cooled, and somewhere in the walls the Veins made a sound she had never heard before, a low, irregular clicking, like a pulse after a shock. The Veins in the corridor hummed the way they always did. Inside the lab, they stuttered and died and stuttered again.

  Kaeso was barely standing. He had one hand on the workbench and the other pressed against the bandage above his left eye, a strip torn from his sleeve that was already soaking through. The instrument with the pinned needle sat between them on the bench. Neither of them had looked away from it for more than a few seconds since the reading pegged at greater than 500 years.

  The voices in the corridor grew louder. Two, maybe three people. One of them authoritative, clipped, asking questions of the others as they walked.

  Lucia looked at the satchel on the floor near the base of the observation chair. Marcus's bag. His notes, his calculations, his two years of careful handwriting.

  She crossed the room in four steps, picked up the satchel, and tucked it under her arm. Marcus's notes. Marcus's handwriting. Marcus's things. Her hands decided before her mind caught up.

  The doorway filled.

  A woman in the dark grey robes of College administration stepped through the ruined frame, followed by two faculty members Lucia recognized from the arcane theory department. The woman's eyes moved across the lab without stopping. Melted anchors. Collapsed spectral array. Cracked stone. Scorch marks radiating from the center of the room like the spokes of a wheel. Cataloguing all of it before she'd finished crossing the threshold, where the bitter smell of scorched bronze caught in her throat.

  "Professor Kaeso." Her voice was deliberately even. "We felt the concussion on the second floor. Is everyone all right?"

  Kaeso straightened. The motion cost him. Lucia saw his hand tighten on the edge of the workbench, the knuckles whitening. But when he spoke, his voice had found the careful, qualified register she knew from lectures and faculty meetings.

  "Administrator Corvus." Kaeso gathered his breath before continuing. "The resonance spectral field inverted during the viewing attempt. Return signal exceeded calibration threshold — cascade failure in the array. Anchors overloaded, crystal lenses shattered under the discharge."

  Corvus looked at the lumps of melted bronze where the anchors had been. "That's consistent with what I'm seeing." She turned back to Kaeso. "Who else was in the room?"

  The pause was less than a second. Lucia counted it.

  "My doctoral student, Marcus Venn, was in the observation chair when the field inverted," Kaeso said. "The energy release caught him directly."

  "Is he injured?"

  "I don't yet know the full extent of what occurred." Smooth. Academic. A door closing. "The inversion produced effects I've never observed. I need to analyze the remaining data before I can make any definitive statements about Marcus's condition or location."

  "His location," Corvus repeated. "You're saying you don't know where he is."

  Kaeso cleaned his glasses on his sleeve. The lenses were cracked. He put them back on anyway. "I'm saying the event produced a displacement that I don't fully understand yet. The resonance path collapsed, and Marcus was caught in the collapse. That's the limit of what I can confirm right now."

  "Professor." Her voice dropped the even register. "A student is missing from a destroyed laboratory. I need a direct answer. Is Marcus Venn alive?"

  The lab ticked. Crystal fragments scattered on the floor.

  "Yes," Kaeso said. "Signature data from the surviving instruments is active and stable. Marcus is alive."

  Lucia's grip on the mark loosened. She'd been holding it hard enough to press the edges white into her palm, and hearing Kaeso say it out loud landed somewhere the instrument reading hadn't reached.

  "Alive and displaced," Corvus said. Not a question.

  "Yes. But the displacement is unlike anything in the literature, and I need time to—"

  "How much time?"

  "Forty-eight hours with the surviving data. I'll have something concrete for your report."

  One of the faculty witnesses, a thin man with ink-stained fingers, was looking at the observation chair. The torn leather strap. The empty seat. His brow creased, and he glanced at the wall where the Veins met the floor. The clicking had stopped. The veins were dark.

  "The Lattice feeds are dead in here," he said. "Whatever happened drew enough energy to burn out the local network."

  "That's consistent with a cascade failure at this scale," Kaeso said. "The priority is understanding the inversion mechanics. I would ask that the lab be preserved as-is until I've had the chance to document everything."

  Corvus was looking at the workbench. At the instrument with the pinned needle.

  "What is that reading?"

  Lucia's hand tightened around the mark again. The bronze edges found the same grooves.

  Kaeso did not look at the instrument. "Residual field data. The resonance path left aftershock readings in the surviving equipment — it confirmed the active signature." He paused, and Lucia watched him choose what came next. "The displacement reading itself requires verification. The instrument took damage in the blast, and I won't characterize the distance until I've checked the calibration."

  Corvus held his gaze a beat longer than before. "This is a recovery. I want a formal report within the week. This lab stays sealed — nothing removed, nothing disturbed." She straightened. "If there is a chance of bringing that student back, Professor, you will have whatever this College can provide. Equipment, funding, personnel. Put it in the report."

  "I will," Kaeso said.

  "His family will need to be notified. I'll handle the initial contact — alive, displaced, the College fully engaged." She paused. "But I expect you to follow up with them personally. Within the week."

  Corvus turned to the faculty witnesses. A few murmured instructions about documenting the damage from the corridor, keeping students clear of the wing. Then they were moving toward the door. The thin man paused, looked back at the instrument on the workbench one more time, and followed.

  Lucia stood very still until the footsteps faded.

  The lab door wouldn't close properly. The hinges had warped in the blast.

  "The stabilizers," Kaeso said. He was still gripping the workbench edge. "The panels along the base of the walls. I need to seal the room."

  Lucia looked. Small bronze plates, flush with the stone, spaced at intervals around the perimeter. She'd seen them in every lab and never thought about them.

  Kaeso pushed off the workbench and made it two steps before his hand found the doorframe. His weight went onto it, all at once, as if something holding him upright had let go.

  "I can't—" He gestured toward the nearest panel. "Palm flat against the bronze. You'll feel the Lattice catch."

  "I work with plenty of stabs in my research. Nothing this standard, though."

  This tale has been unlawfully lifted from Royal Road. If you spot it on Amazon, please report it.

  "Stabilizers." The correction was reflexive, even half-collapsed against the doorframe. "And prebuilt is all we need to protect the lab. Nothing fancy like whatever you're running in your research. They pull from the corridor's trunk lines — still live."

  She knelt by the panel nearest the doorframe and pressed her palm flat against the bronze. Warm metal, then warmer. After a breath the Lattice caught — a low hum that traveled up through her wrist and settled in the bones of her hand.

  "Key it to my signature and administration," Kaeso said. "No one below that opens the seal."

  She held the contact and thought of his name. The bronze held warm under her palm, humming, but nothing closed.

  "It won't finish without me." Kaeso pushed off the doorframe. Two steps to the panel, each one costing him. He knelt beside her and pressed his hand flat next to hers on the bronze. The hum deepened, and she felt the seal catch, his signature locking into place.

  His hand stayed on the plate. "Environment controls. Temperature, moisture, airflow." His fingers spread against the bronze. "The stabilizers hold the room steady. Nothing in here degrades while the seal is live."

  The air shifted. Drier, and perfectly still. The dust that had been drifting through the corridor light hung motionless. Along the base of the walls, the other panels answered in sequence, each flickering amber as the seal traveled the perimeter.

  The lab was sealed.

  Kaeso exhaled. His shoulders dropped. For a moment he looked his age, and more.

  "We need to—" he started.

  "You didn't ask me."

  The words came out flat. Lucia hadn't planned them. They were just there, the way the satchel grab had been.

  Kaeso blinked. "Lucia..."

  "You told her he's alive. You told her he's displaced. You told her you need resources to find him." She held up the mark. Dark bronze. No glow. "That instrument hit the stop at five hundred years and the needle is still pulling. He's past anything that machine can read, and you just let that woman walk out thinking this is a rescue that takes weeks."

  "I told her what she needed to hear in order to—"

  "You tollin lied."

  Neither of them moved. Crystal fragments glittered on the floor between them, catching the corridor light that leaked through the warped door.

  "I made a judgment," Kaeso said quietly. "In the moment. About how much to share."

  "A judgment you made for both of us without asking either of us."

  "There wasn't time."

  "There were five minutes between when you got the reading and when she walked through that door. Five minutes where you could have turned to me and said, 'Lucia, this is what we know, what do we do?'"

  Kaeso took his glasses off. Put them back on. The crack in the left lens split the lab into two overlapping images. "If I had told her Marcus is alive so far in the past that our instruments can't even measure the distance, what happens next?"

  "The College helps us bring him back." Her voice didn't waver. The rest of her wasn't as sure.

  "The College studies what happened. They convene a panel. They bring in temporal researchers from every department and three other institutions. They analyze the displacement, the resonance path, the signature lock. They publish papers. They apply for funding." His hands went to the workbench, pressing flat against the surface. "And somewhere in the middle of all that, Marcus becomes the experiment — not the student."

  "That's speculation."

  "It's pattern recognition. Can you name a single institutional response in the history of this College where the institution chose the person over the discovery?"

  Lucia said nothing. The hum from the corridor filled the gap.

  "I can't either," Kaeso said.

  He straightened. "And this isn't a routine experiment failure. This is evidence that physical temporal displacement is possible. Not viewing. A living person, moved through time." His voice dropped. "If the College reports that, it doesn't stay in the College. Every institution with a temporal program wants the data. The Senate wants oversight. And the focus stops being how to bring Marcus home. It becomes how to do it again."

  She turned toward the door. Then turned back. "And conveniently, if we tell the College everything, they take control of the research. They take control of the lab, the instruments, the data. They take it out of your hands."

  Kaeso held her gaze. "Both things can be true."

  She tolling wanted to hit him. The danger was real. Oh Cass, if time travel was possible, every power in Aeterna would want it, and Marcus would become an afterthought.

  "So we lie," she said. "That's what you're saying. We tell the College he's alive and displaced, get them to fund the research, and keep the part where we don't even know how far he's gone to ourselves."

  "We tell them what I told them. The truth, without the part that turns Marcus into a phenomenon."

  "And his mother?"

  Kaeso's hands, flat on the workbench, curled. His jaw shifted.

  "His mother expects him for seventh-day dinner," Lucia said. "Someone from that woman's office is going to tell her that her son is alive and displaced and the College is working on bringing him back. And his mother is going to think that means days. She's going to set a place at her table on seventh-day and wait for him to walk through the door." She stepped closer. "How long do we let her?"

  Kaeso didn't answer.

  "Because I'm not telling her the truth," Lucia said. "I didn't start this. If you want to give that woman hope you can't deliver, that's your decision. But every seventh-day she sets that place is on you."

  Kaeso lowered his eyes. The blood from his bandage had traced a line down the side of his face and dried there, and he hadn't wiped it.

  "I don't have a good answer for that," he said.

  "I know."

  They stood there. The lab ticked and settled around them. From the corridor, footsteps passing, students who didn't know anything had happened, or who knew only that there had been a noise and that the temporal wing was being sealed.

  Lucia hadn't said yes. She knew that, and Kaeso knew it. But the official had been told a story, and the lab was locked, and the instrument with its pinned needle was on the other side of a sealed door. By not correcting the lie in the moment it was told, she had let it become real.

  "I need air," she said.

  She walked away from the warped door and down the corridor. A few steps and the air was noticeably cleaner, the scorched bronze fading into nothing. The Lattice hum met her like a hug. Warm, steady, alive. The sound of home. She leaned against the wall and let it hum through her.

  * * *

  Three days later, Lucia sat in Marcus's study carrel in the College library and turned pages of his handwriting.

  The carrel was a half-enclosed desk space in the western stacks, tucked between two shelving units that smelled of old binding glue. Marcus had claimed it in his second year and held it ever since, the one spot with good light and a partial view of the courtyard elms. His things were still there. The College hadn't cleared it. They had no reason to; the official story was "alive, displaced, recovery underway."

  Books stacked by subject. Handwritten notes pinned to the wooden partition, his script dense and angular, the kind of handwriting that pressed hard enough to leave grooves in the parchment beneath. A dried fig, half-eaten, on a saucer that had been there long enough to leave a ring. A spare pen. A folded napkin from the dining hall with a scribble on it that might have been a date calculation or might have been a shopping list.

  She wore Marcus's citizen's seal on a cord around her neck, over her own. Two discs against her sternum. Hers glowed the usual yellow-green, cycling normally. His had gone dark. Not amber, not red, not any color in the tithe spectrum. Just sat there, still searching for Marcus.

  Every evening since the explosion, she came here after her seminars. Sitting in his chair. Going through his notes with the systematic thoroughness he would have used himself, if he'd been the one searching. The satchel she'd grabbed from the lab floor sat open on the desk. Inside: three months of thesis preparation. Target date calculations. Resonance calibration charts. Annotated copies of the Chronicle of Cassius and the Commentaries of Septima, his handwriting filling the margins.

  Three evenings of his handwriting and she still couldn't tell the breakthroughs from the dead ends. Marcus had two years of the Founding Era in these pages. Something in them had to be useful. It had to be.

  Another page. More calibration notes for the third attempt. Target windows, resonance frequencies, spectral alignments. She turned it, and turned the next one. Marcus's handwriting, page after page, all of it precise and none of it useful.

  And in the margin, in smaller script, a note to himself. The ink slightly different, as if he'd come back to it later with a different pen.

  11% return signal increase. Not calibration drift -> checked twice. Why is the target already aligned with our frequency?

  She almost turned past it. A margin note, a question. Marcus left margin notes the way other people left crumbs. Everywhere, half-finished, most of them leading nowhere.

  But this one had an arrow. Drawn in the same later ink, pointing to the back of the page.

  She turned it over.

  The back was covered. Not a margin note. Working notes. Dense, cramped, Marcus's handwriting when he was thinking faster than he could write. Lists and half-finished calculations, arrows connecting entries, numbers scratched out and rewritten. It was unorganized chaos, like any problem Marcus found captivating.

  The top entries were crossed out. Equipment drift -> re-calibrated twice, holds steady. Ambient Lattice bleed -> shielded array, negative. Stronger-than-expected target conditions -> possible, but doesn't explain acceleration.

  Below the crossed-out entries, the handwriting changed. Smaller. Slower.

  Signal isn't reflecting. It's compounding. Two-source pattern. Something at the target end is pulling back.

  Then a line of arithmetic she couldn't fully follow: resonance coefficients, frequency ratios, a formula with two variables circled and connected by an arrow.

  Below that:

  For compounding, need a matched signature at target coordinates. Need a source, with Resonance Affinity. But how is their something here resonating with the past?

  And at the bottom of the page, barely legible, the pen pressed hard enough to gouge the parchment:

  Then what am I looking at?

  She stared at the pages. She could hear him asking the question, the slight tilt of his head, the way he'd tap the pen against his lower lip when a piece of data didn't fit his model. Half-formed and interesting. The kind of problem Marcus would take home and work on at his kitchen table, not the kind he'd bring to Kaeso before it was finished.

  And then he'd sat down in the chair the next morning and ran the experiment anyway.

  Then the anger exploded. At Marcus, for documenting the problem and walking past it anyway. At Kaeso, for not stopping the experiment. At the fig on the saucer, dried and hard, left behind by someone who assumed he'd be back.

  She slid a scrap of parchment between the pages to mark the place, closed the notebook, and put it in the satchel, carefully buckled the flap.

  The library was nearly empty. Late evening, the floating orbs dimmed to their overnight glow. The hum in the walls was quieter here than in the research wing but never absent.
