There are two kinds of people in the world. The ones who look at the ocean and see water. And the ones who look at the ocean and think something is down there.

  I am, unfortunately, the second kind.

  It was 2:47 in the morning.

  I know that because I checked my phone. Not because I had somewhere to be. I checked it the way you check a clock when you've been sitting in the dark for too long and you need something to prove that time is still moving.

  Three screens. All of them blue. All of them showing the same thing.

  The ocean.

  Specifically, a stretch of the Pacific that every official map in the world had agreed, for the last sixty years, was absolutely nothing. No islands. No shipping routes. No name. Just water and the kind of silence that maps use when they want you to stop asking questions.

  I had been asking questions anyway.

  The signal showed up at 2:51.

  Three pulses. A pause. Three more.

  I was on my feet before I even realized I'd stood up.

  My fingers flew across the keyboard. Save timestamp. Save coordinates. Save frequency. My hands were shaking a little and I hated that, genuinely hated it, because this was the two hundred and fourth time I'd seen this signal and you'd think by now I'd be able to watch it without feeling like my heart was trying to climb out of my chest.

  You'd think.

  Nine seconds. Then it was gone.

  Seventy-two hours. You'll be back in seventy-two hours.

  I added the entry to my spreadsheet. Date. Time. Frequency. Duration. Coordinate variance from last sighting: 0.003 degrees. I had two hundred and four of these entries now. Eighteen months of them.

  Two hundred and four times, something down there had breathed.

  And I was the only one paying attention.

  The research center smelled like old carpet and bad decisions. I know because I walked into it every morning. And every morning it reminded me that I was the weird one.

  I had gotten three colleagues to show up, which was already more than last month. Dr. Harven stood at the back with his arms crossed. Two younger researchers, Nadia and Cho, sat at the table looking at their phones.

  Fine. I'd work with that.

  "I'll keep it short," I said.

  Harven said nothing. Just looked at the screen.

  I brought up the waveform. Played the signal as audio. Three soft pulses. A gap. Three more.

  "This repeats every seventy-two hours. Consistent frequency, consistent location. I've been logging it for eighteen months."

  Nadia looked up.

  "That's the Alosilaztion thing again."

  "It's the signal thing. The name comes later, after you actually look at the evidence."

  I pulled up the next slide. Satellite composite over deep-ocean topography.

  "This region has been marked geologically inactive for over sixty years. No tectonic movement. No volcanic activity. Nothing that should produce a repeating electromagnetic signature at this frequency. Nothing."

  Harven uncrossed his arms just long enough to scratch the side of his face. Then crossed them again.

  "So what are you suggesting?"

  "I'm not suggesting anything. I'm showing you data."

  "Leon."

  His voice had that specific flatness it gets when he's being patient. I knew that voice. I'd been on the receiving end of it for two years.

  "We've looked at this. Multiple times. The pattern is consistent with deep-water thermal venting combined with satellite artifact. That's been the conclusion."

  "The conclusion came from assuming it was natural before ruling out that it wasn't."

  "Because that's how science works."

  "Only when nobody's motivated to ignore a result."

  The room went quiet.

  Cho put down his phone. Nadia looked between me and Harven like she was watching a slow-motion collision.

  "You have more slides?"

  "Twelve more."

  "Show me the last one."

  I clicked ahead.

  The final slide was a scan of a hand-drawn map. 1,200 years old. Portuguese archive, Lisbon, never digitized. It showed a stretch of the Pacific. In the middle of the water, a landmass. Small. Detailed. And in the margin, a note in old Latin that a translator I'd paid out of my own pocket had read to me at midnight:

  They went beneath.

  Nobody said anything.

  Harven set down his coffee cup.

  "That's a medieval cartographer's error. They made those all the time."

  "Seventeen different maps. Four different centuries. Four different cultures with no documented contact with each other. All of them show a landmass in the same region. And then, after approximately 1400 AD, every single one stops. Not changes. Not moves. Stops. The region goes blank, simultaneously, across all of them."

  Silence.

  Then Nadia laughed. Not mean. Just the kind of laugh people do when something is either really interesting or really sad and they can't tell which.

  Support creative writers by reading their stories on Royal Road, not stolen versions.

  "Leon. You know how this sounds, right?"

  I closed my laptop.

  "Yeah. I know exactly how it sounds."

  I left before anyone else did.

  My uncle Marcus makes rice wrong. Too much water, wrong heat, stirs it when you're not supposed to. I stopped correcting him three years ago. Some things aren't worth the fight.

  He was at the stove when I got home. Didn't turn around but I knew he already knew how it went. He always does.

  "How'd it go?"

  "Same as always."

  "They laughed?"

  "Harven did the polite version. Which is somehow worse."

  Kai was at the table with a bag of crackers and his phone. He looked up when I sat down.

  "The underwater kingdom rejected you again."

  "I'm not talking about it tonight."

  "You're always talking about it. Even when you're not talking about it, you're still talking about it."

  Theo came out of the hallway with two cans of soda. He set one in front of me without being asked. I didn't say thank you but he knew I meant it.

  "Mira says hi. Also she says, quote, tell him the signal could still be tectonic."

  "It's not tectonic."

  "She knows. She just doesn't want you to lose your mind."

  Marcus put a bowl down in front of me. Overcooked rice and some kind of stew that looked better than it deserved to. He sat across from me.

  I looked at him.

  "Do you believe me?"

  He didn't answer right away. That's how I know he's actually thinking about something instead of just being polite.

  "I believe you're not stupid. And I believe you believe it. The rest of it... I need more."

  "I know."

  "Then go get more."

  I picked up my fork.

  "I found something. In the old Karesh archive records. There's a reference to a secondary chamber. Underground. Sealed. The main library burned but the records say not everything was in the main building. Someone built a lower level after the surface structure was already finished. Like they wanted the important things somewhere fire couldn't reach."

  Kai stopped scrolling.

  Theo put down his soda.

  Marcus said nothing. But he stopped eating.

  "When are you going?"

  "Tomorrow."

  The ruins of the Karesh Archive sat at the edge of the desert like a wound that healed wrong. Archaeologists had picked it clean three separate times. They all agreed there was nothing left worth finding.

  They were wrong.

  I arrived at noon and went straight to the eastern side. Not the main site. The section every report called structurally compromised and left alone.

  The 1923 survey map, the one nobody had bothered to digitize, showed a dotted line running south from the outer wall. I had printed it at 3 AM two nights ago and stared at it until it started making sense.

  I almost missed the opening anyway.

  It looked like every other collapsed section of wall. A half-meter gap between two fallen stones. Dark below. A draft coming up from it, faint, stale, like air that hadn't moved since before I was born.

  I crouched in front of it and clicked on my flashlight.

  Stone steps. Going down.

  ...

  I went in.

  Narrow. Steep. I counted them as I descended.

  By forty it was cold enough to feel through my jacket. By sixty I could see my own breath. By eighty the walls changed. The rough cut stone became something smoother, fitted with a precision that felt wrong for the age of everything above it. Different builders. Different century. Maybe different world entirely.

  Ninety-three steps. Then the stairs ended.

  The chamber was enormous.

  High ceiling. Walls that curved inward slightly. And in the center, sitting on a raised stone platform like it had been put there and told to wait, a sealed container roughly the size of a suitcase.

  I stood in the entrance for a while without moving.

  There was no dust on it.

  Everything else in the room was buried under centuries of grey. The floor. The walls. The platform itself. But the container was clean. Not almost clean. Clean, like it had simply decided to stay that way until the right person showed up.

  I crossed the room.

  Up close it wasn't any metal I recognized. The surface had a texture like something woven too fine to see. No seams. No lock. No mechanism of any kind.

  I pressed my hand against it.

  It opened.

  Not violently. No click, no hiss. It just parted, slowly, the way a door opens for someone it already knows.

  Inside, wrapped in something that wasn't cloth and wasn't plastic but felt like both, was a book.

  Old. Thick. Dark cover that didn't flex. The title was cut directly into the surface in letters that were half familiar in a way I couldn't explain, like a language that had almost become something else a long time ago.

  ALOSILAZTION A Record of What Was, and What Remains

  My hands weren't shaking.

  I'd gone somewhere past shaking.

  I sat down on the stone floor, back against the platform, and I read.

  Most of it was dense script I could only partly make out. Old language, formal, the kind of writing that knows it's being kept for someone who will arrive very late. But some lines stood completely clear, like they'd been written for whoever came last:

  When the surface world forgot how to live without burning itself down, we chose not to burn with it.

  The city did not fall.

  The city chose to descend.

  We are still here. We have always been here.

  Whoever finds this record was meant to find it.

  I sat there for a long time.

  I heard it before I saw it. A small sound. Rising pitch. Like something deciding to wake up.

  In the far corner of the chamber, something was moving.

  Small. Roughly spherical. Dark surface that absorbed light instead of reflecting it. It rose from the floor slowly, the way a bubble moves through something thick. Unhurried. Like it had done this before and wasn't worried about the outcome.

  I did not move.

  The sphere rotated once. A ring of dim light appeared around its middle. Then two brighter points near what might have been a face, not exactly eyes but the idea of them, and they swept across the room until they found me.

  They stopped.

  The hum it was making resolved the way a radio resolves when you're close enough to the tower.

  System initialized.

  I said nothing.

  User proximity confirmed.

  Still nothing.

  It drifted closer. Slowly. Almost carefully. It stopped at about two meters and hovered there, the ring of light pulsing in a slow rhythm that, after a moment, I realized matched my own heartbeat almost exactly.

  That was the most unsettling part.

  "Guide protocol active."

  A pause.

  "It has been a long time."

  I found my voice.

  "How long?"

  The sphere rotated. The lights shifted.

  "Seven hundred and fourteen years, four months, and approximately nine days since last confirmed human contact. Give or take seasonal drift in the atomic reference."

  I looked at it.

  "What are you?"

  "A messenger. A guide. A record."

  A shorter pause this time.

  "A companion, if that becomes useful."

  I looked at the book in my lap. At the container. At the chamber around me, impossible and perfectly preserved under a ruin that everyone agreed had nothing left to give.

  I looked back at the sphere.

  "You're from Alosilaztion."

  The lights on it shifted. Warmer. Steadier.

  "Yes."

  Something in my chest came loose.

  I don't have a better word for it. It wasn't triumph and it wasn't relief. It was quieter than both. It was the feeling of being told for eighteen months that you were wrong, by everyone you respected, and then standing somewhere that proves you weren't.

  It felt like putting something heavy down.

  "My name is Leon."

  The sphere drifted a little closer.

  "I know. We have been waiting for someone who would not stop looking, even after everyone else told them to."

  The lights brightened slightly.

  "You took longer than expected. But you are here."

  I almost laughed at that.

  Almost.

  The hologram appeared without warning.

  The sphere opened and the ring of light expanded outward and became something else. The air changed. A projection bloomed between us, three dimensional, precise, a section of the Pacific Ocean rendered in cool blue light with the seafloor scrolling slowly underneath like a map being drawn in real time.

  One point pulsed in the deep water.

  I recognized the coordinates immediately.

  I had been staring at them for a year and a half.

  "That's the signal."

  "That is the city."

  I stepped forward into the projection. The light moved over my hands.

  Far below the ocean surface, past the deepest trench line, the shape of something enormous. Not geological. Too regular. Too deliberate. The kind of regularity that only comes from people who meant to build something that would last.

  Buildings. A skyline pressed into the seafloor, invisible unless you knew exactly what you were looking at.

  I hadn't known, all those months ago.

  I knew now.

  "How do I get there?"

  "That is what I am here to help you figure out."

  A pause.

  "The path is not simple. The city has not had surface visitors in seven centuries. There are people there who will not welcome you."

  "And people who will?"

  "...That remains to be seen. But the city placed this record here for a reason. And the city does not act without reason."

  I looked at the glowing point for a long time.

  Eighteen months. Two hundred and four signals. Twelve slides nobody would look at. A room that smelled like carpet and quiet dismissal. My uncle's voice saying go get more.

  I took out my phone and called the first name in my contacts.

  Two rings.

  "Leon? What happened?"

  "Call Marcus and Theo and Mira. Tonight. Tell them to come to mine."

  "Why, what did you find?"

  I looked at the sphere floating beside me. At the city glowing in the dark beneath the water.

  "Everything."
