ARC III: Murder Terrarium Begins

  Chapter 21: CITY OF GHOSTS

  Entry into unclaimed structures does not establish ownership, priority, or right of return. Access shall be treated as conditional and revocable where legacy systems exhibit unpredictable mechanical behavior, novel biomatter presence, or unexplained energetic gradients. Personnel are reminded that “intuitive safe routes” are not evidence of protection—only evidence that loss has not yet been booked.

  ?

  The gate was not a door.

  It was thickness.

  Not glass. Not mist. Not a pressure seal with a polite hiss and an idiot light that turned green when you didn’t die. The opening in the dome’s inner wall looked like it had been carved out of the air and then regretted. The space inside it had weight—like you could lean your shoulder into it and feel it push back.

  Above it, the lattice brightened. For a heartbeat, the field ribs became almost solid—great translucent beams overhead, refracting sunlight into slow-moving rainbows like someone had put a prism the size of a continent inside the sky.

  Then the aperture thickened again. Not visibly—not in a way my eyes could point at and say there—but my suit’s field sensors coughed up warning icons about pressure gradients and tiny curvature deviations like they’d suddenly remembered they were allowed to be scared.

  I stood at the threshold with one boot on our side, one boot hovering over the other, and tried to convince my body that hesitation was a reasonable career choice.

  “Vitals?” I asked, because if I pretended this was normal, the part of my brain that wanted to sprint back to the lander might get bored and leave.

  Mercy’s voice came through my helmet, crisp and too calm for the moment. “External pressure stable. Oxygen fraction within tolerable ranges. Trace compounds present; filters remain engaged. Thermal gradient minimal. Radiation baseline elevated compared to Earth, consistent with location.”

  Chloe made a sound that was half laugh, half sob. “You’re saying the air won’t kill us immediately.”

  “I am saying the air is not currently attempting to kill you faster than you can walk away,” Mercy replied.

  Trevor’s exhale fogged the inside of his visor for a heartbeat before his suit cleared it. “That is… an unsettling way to phrase that.”

  Frankie floated at my shoulder as a thumb-sized hologram, squinting into the thickness like he could bully it into behaving by glaring hard enough. “I don’t like it,” he announced.

  “You don’t like anything,” I said.

  “I like sandwiches. I like winning arguments. I like when my electromagnetic environment is not sticky.”

  “Sticky?” Chloe echoed.

  Frankie jabbed a tiny hand at the air. “Watch.”

  He “touched” the threshold with his projection, and his haptics kicked back into our comms as a distorted little squeal—like someone rubbing a balloon the size of a planet.

  Frankie recoiled. “OH. NO. Absolutely not.”

  “What?” Trevor asked, instantly more alarmed by the AI’s tone than by anything Mercy had just said about trace compounds.

  “It feels like petting a cat made of static,” Frankie said. “Except the cat is the size of Texas and it hates you.”

  Trevor’s voice went automatically sharp, like the universe had handed him a form to fill out. “No one touches anything. No one takes their helmet off. No one—”

  “—licks alien infrastructure?” I offered.

  Trevor paused. “Correct. No one licks—”

  “Put it on the checklist,” Frankie said solemnly. “Step one: do not french-kiss the haunted parking garage.”

  Chloe made a noise that was either laughter or the beginning of a breakdown.

  This story originates from Royal Road. Ensure the author gets the support they deserve by reading it there.

  I stared at the thickness and made my decision the way I made most decisions: by stepping forward before I could talk myself out of it.

  Crossing it felt like wading through gelatin that wanted very badly to be a thought instead of a substance. It wasn’t pain. It was worse—my body remembering every scan, every map, every time a machine had looked at me and decided I was a set of numbers, and feeling that memory light up again as if something had just flipped through my specs out of boredom.

  Sound changed first.

  Not volume—shape. My foot hit the terrace and the crunch of grit came back at me a fraction late, hollowed, like the air had to think about it before it agreed. My own breathing sounded closer, trapped in a smaller room than my helmet. The soft servos in my suit took on a faint chorus, like there were three of them instead of one.

  I took another step. My inner ear complained. The horizon tilted for no reason, then righted itself. The suit’s balance assist twitched like it had been slapped.

  Under my boot, the terrace surface had a pattern—triplet spirals worn smooth by feet that hadn’t touched it in a very long time. The grooves caught dust the way old sidewalks caught gum, and I hated that my brain wanted to read it as ordinary.

  “Okay,” I said, because my mouth needed something to do that wasn’t screaming. “That’s… weird.”

  Chloe crossed behind me with the kind of joy you only saw in people who didn’t make their living by surviving. Her boots hit the terrace and she let out a small, involuntary “oh.”

  Trevor followed with the stiffness of a man walking into a courtroom where the judge was gravity itself. “We should… document the threshold effects,” he began.

  “We are documenting them,” I said. “With our bodies.”

  Frankie drifted through last, sulking. The moment he crossed, his little projection fuzzed, then snapped back into focus, like the thickness had briefly tried to edit him.

  “Venus has texture,” I said.

  Frankie’s eyes narrowed. “Cool. Hate it.”

  ? ? ?

  And then the city hit me.

  Not the way a skyline hit you back on Earth, where buildings rose against a familiar sky and the distance had a kind of human mercy to it. This was not a skyline.

  This was terrain.

  Terraces spread out like continental shelves, stacked and stepped into the hazy distance until they merged with the dome’s curvature. Towers broke up through the layers like mountain ranges. Elevated transit ribs—broad, arched spines of something between road and rail—ran straight for kilometers, then vanished into the pale light-fog that wasn’t weather so much as distance made visible.

  From the inside, the dome didn’t feel like a dome at all. The sky arched overhead in a hazy, washed blue, streaked with high, thin clouds and shot through with faint straight lines—undersides of lattice ribs, half-transparent, their surfaces alive with slow-moving light. If I stared too long, my eyes stopped agreeing on what was “near” and what was “far.”

  Somewhere far away, a ribbon of light drifted along an avenue the width of a river, slow and steady, like a glowing tide. Another ribbon crossed it at a different height, and for a second it looked like a three-dimensional map of a place no one could ever fully see at once.

  Overgrowth clung to the terraces, but it wasn’t the sad, chaotic ruin-green of abandoned human cities. It looked… established. Opportunistic, yes. Aggressive, sure. But structured. Mats of something like moss braided into thick ropes. Fungal fans the size of umbrellas. Tendrils that crawled up the sides of towers in deliberate spirals.

  The whole place looked like someone had shaded an architectural rendering with rainforest.

  No trash. No bodies. No broken glass glittering in the cracks like a confession.

  Chloe’s head turned slow, visor sweeping the horizon. “There are… districts,” she breathed. “You can see the boundaries by texture. By plant type. By—”

  “By how much we’re going to die if we walk into the wrong one,” Trevor finished, voice tight.

  Frankie made an appreciative noise. “Oh wow,” he said. “We are the only litter.”

  I couldn’t help it. A laugh slipped out of me, sharp and short. “Yep. We’re the only new thing this place has had to deal with in—what, Mercy?”

  Mercy paused. Not long. Just long enough to make the silence feel deliberate.

  “I do not have a meaningful estimate,” she said. “But I can confirm the scale of habitable infrastructure visible from this terrace exceeds two hundred kilometers in radius.”

  Chloe made a sound that might have been worship.

  Trevor made a sound that might have been nausea.

  I stared at the endless terraces until my brain stopped trying to put them into human categories. My legs already felt tired just looking at it, like the city could drain you through your eyes.

  Then my HUD flashed a little symbol as Mercy piped in suit sampling data.

  “Focus,” Mercy said gently. “You are still standing on an alien terrace. Please perform the initial safety recon before you fall in love.”

  “Can’t promise anything,” Chloe muttered.

  ? ? ?

  We did the first practical thing, because practical things kept you alive.

  Chloe launched a drone with a micro-sampler, a little beetle of metal and sensor pods that buzzed out over the terrace edge and dipped into the air like it was tasting it. The drone’s camera feed painted the overgrowth in false color—heat maps, particulate density, spore counts climbing like numbers in a horror movie.

  “Spore load is… delightful,” Chloe said, voice bright with scientific glee.

  Trevor’s shoulders tightened. “Delightful is not a word you should use for airborne biology on an alien planet.”

  “It’s not biology,” Chloe said automatically, then hesitated. “It’s… okay, it’s probably biology.”

  Chloe flicked her wrist and threw up her own readout like she was presenting a magic trick. “Local gravity is point-nine-eight Earth. Ambient pressure one-point-zero-four atmospheres. Composition—ninety-one percent nitrogen, seven percent oxygen, trace gases, plus a frankly upsetting amount of things I don’t have names for yet.”

  Trevor stared at the oxygen number like it had personally insulted him. “Seven.”

  “Seven,” Chloe confirmed, grin too wide.

  “Filters remain engaged,” Mercy reminded. “No hero-breathing.”

  “I wasn’t going to,” Trevor said immediately, the way a man insisted he wasn’t going to do a crime while already holding the crowbar.

  I knelt and scraped a bit of terrace surface with my glove. The “stone” didn’t flake. It didn’t crumble. It resisted in a way that made my teeth itch, like I was scraping a ceramic that had been printed at the molecular level.

  The sample came away as a thin dust of glittering grains. Not sand. Not concrete. Something more uniform.

  “Material microstructure is too consistent,” I murmured.

  Chloe leaned over my shoulder so hard she almost headbutted my helmet. “Let me see—”

  “Later,” Trevor said sharply. “We set camp first.”

  Frankie floated between us, big now—human-sized, his projection using more light, more definition. He “leaned” toward the scraped patch like a curious raccoon.

  There was a brief burst of EM hiss over comms. Frankie yelped in a way that would have been embarrassing if he’d had vocal cords.

  “NOPE,” Frankie declared, snapping back upright. “That surface bites.”

  “It doesn’t bite,” I said.

  “It nibbles. It’s worse. It’s flirtatious.”

  Chloe laughed, then coughed, then laughed again. “We have to name it.”

  “We are not naming the floor,” Trevor said.

  “We named the ship’s stress patch ‘Corporate Logo,’” Frankie reminded him sweetly. “We have a tradition.”

  Trevor’s response was a long, pained silence that told me he was imagining paperwork.

  As we talked, I listened.

  Not for voices—there were no voices. The city did not whisper. It did not breathe. But the way sound moved here was wrong. Our footsteps carried farther than they should, then vanished abruptly like they’d hit a soft wall. The drones’ buzz muted at certain angles. When Chloe turned her head, the hiss of her suit fan shifted pitch, as if the air had different densities in different directions.

  It wasn’t hostile. It wasn’t friendly.

  It was just… not made for us.

  “Okay,” I said. “Camp. Close enough to run for the gate if we have to. High enough to see. Hard back.”

  Do you think I should return to longer chapters?
