I Work Security at a Convention Center. It is VERY Strange Here.

I've been working security at the Riverside Convention Center for three years. Three years of 12 hour shifts, watching cameras and walking empty hallways. That's me. Guy who takes a job and just keeps showing up. The work wasn't complicated.

Monitor the feeds, walk the building twice a shift, lock up when everyone leaves, make sure nobody steals the industrial carpet cleaners or whatever. It paid 15 an hour, which covered my studio apartment on Maple Street and kept my 2006 Subaru running barely. That car needed new brakes, but I kept putting it off most nights.

Blurred together, same routine every time. Contractors cleared out around 7:00. Cleaning crews showed up at 8:00. Then six hours of nothing but my footsteps echoing off concrete walls and the hum of fluorescent lights that never quite turned off. The sound bounced weird in those corridors, made everything feel bigger and emptier than it was.

I'd taken the job right after dropping out of Community College, Told myself it was temporary while I figured things out. That was three years ago. Still figuring, I guess. Thursday night started like every other. I clocked in at 8 and nodded to Kenny Hubbard.

He was the day shift supervisor, 40 something guy who spent most of his time on his phone. He barely looked up when I walked in, just kind of grunted and kept scrolling through whatever he was reading. Anything happened today? I asked. Nah, he didn't look up.

Medical thing wrapped up around 7:30. Last guy out was some vendor with a van full of hospital beds. Kenny packed up his stuff. Thermos paperback book with a cracked spine key ring with too many keys for a job this simple. He headed for the door without saying goodbye.

That was Kenny. Not unfriendly, exactly, just somewhere else in his head most of the time. The Convention Center had hosted a medical equipment Expo that week, one of those trade shows where companies set up booths and handed out brochures nobody reads. I'd watched pieces of it on the cameras, lots of guys in polo shirts pointing at machines I couldn't identify.

Hospital beds, wheelchairs, some kind of scanning equipment that probably cost more than I'd make in five years. The last vendors had cleared out by 7:30, like Kenny said. I'd seen them on Camera 3 loading a white panel van, two guys in khakis struggling with a metal cart full of pamphlets. They'd taken forever, kept stopping to check their phones and argue about which boxes went where.

The cleaning crew showed up right on schedule. 8:00 Raven Bridges LED them in through the loading dock. She was the supervisor, mid 30s, blonde hair always pulled back, voice that carried across the whole building when she needed it to. Professional got things done. I watched on Camera 6 as her crew spread out across the main exhibition hall.

Three people pushing industrial floor buffers. Those machines were loud. Even through the camera feeds I could tell they were making noise, the kind of deep mechanical rumble that you feel in your chest. One of the workers was new young guy who kept stopping the buffer to check if he was doing it right.

Raven walked over and showed him how to overlap the cleaning pattern. She pointed at the floor and drew invisible lines with her finger. He nodded and started again. I liked watching the cleaning crew work. There was something satisfying about it.

They'd start with a messy space full of booth remnants and coffee cups and vendor trash. Two hours later, it'd be spotless, ready for whatever event was coming next. By 10:00, Raven had let her team out through the loading dock. I watched them pack their equipment into a Gray van with tri-county Cleaning Services printed on the side.

Raven did a final check of her clipboard, made sure everyone was accounted for, Then they drove off into the night. That left me alone with the building. I pulled up the security panel on my computer. 24 exterior doors, all showing green locks except for the main entrance, which stayed unlocked until I did my final sweep.

I clicked through the camera feeds. Loading dock clear. Parking lot empty except for my Subaru and a couple's cars that belong to the hotel next door. Everything looked normal, quiet. I hit the remote lock button for all exterior doors.

24 green lights turned red. The building was sealed. Time for my first patrol. I grabbed my flashlight from the desk drawer and clipped it to my belt. The thing was heavier than it needed to be.

Some kind of tactical model the company had ordered in bulk. Probably thought it made us look more professional. I stood up and stretched 12 hours ahead of me. 6 more patrols after this one, then home to my apartment where I'd microwave something and watch Netflix until I fell asleep. That was the plan, anyway.

I walked toward the main corridor that led to the exhibition hall. My footsteps echoed off the polished concrete floor. The sound followed me like it always did, sharp clicks that bounced off the walls and came back distorted. Just another Thursday night at the Riverside Convention Center. I figured I'd walk the building, check the doors, maybe read a magazine I'd found under my bed.

Kill time until 6:00 AM when Kenny showed up and I could go home. That was it. Simple routine, nothing special about it. I kept walking toward the main hall to begin my first patrol. The main hall hit me with that sharp smell of disinfectant mixed with carpet cleaner.

Tri-county had done their usual thorough job. I swept my flashlight across the empty space, and the beam caught rows of abandoned booths and leftover signage that vendors hadn't bothered taking down. Some company called Medtech Solutions had left a banner hanging crooked over booth 12. Another one for Advanced Surgical Supply, was half rolled up on the floor, like someone gave up halfway through packing the Expo.

People always left behind random stuff forgotten. Business cards scattered on tables, extension cords coiled in corners, half empty coffee cups that cleaning crews somehow missed. That was normal. What wasn't normal was finding entire setup still running. After everyone cleared out, I stopped at booth 47.

Dan Vargas had been here earlier around 5, packing everything into a yellow U-Haul efficiently. I'd watched him on Camera 6 while finishing my shift report. The guy folded tablecloths like he was wrapping Christmas presents and stacked brochure boxes with engineering level accuracy. Took him two hours to load everything, checking his clipboard after every trip to the truck.

Now a single display case stood in the center of the empty booth space. The thing was waist high, maybe 3 feet across, glass top and sides, with a brushed aluminum frame that caught my flashlight beam and threw it back in sharp angles. Inside sat what looked like a medical device. Sleek white plastic housing about the size of a desktop computer, but more rounded, organic looking I guess.

It had a small digital screen on the front that was currently dark. A printed card leaned against the base of the case block letters in aerial font. Demo unit do not remove. I pulled out my phone and scrolled through messages looking for anything from Luna Bush about late deliveries or equipment pickups. Sometimes vendors arranged after hours collections and forgot to tell security.

Luna was pretty good about keeping me informed, but things slipped through occasionally. Nothing. No missed calls either. I walked closer to get a better look at the setup. The display case was professional grade, probably cost more than my car.

Heavy glass with perfect seams and no visible latches or hinges. The kind of thing you'd see in a high end electronics store or medical showroom. My reflection stretched across the curved glass as I moved around it, distorting like a funhouse mirror. The device inside had no visible manufacturer logo, just smooth white plastic with subtle curves and that dark screen.

No buttons or switches that I could see. No power cord either, which seemed weird for medical equipment. Most of the stuff I'd seen at these Expos needed to be plugged in for demonstrations. Heart monitors, beeping surgical simulators, running test programs, that kind of thing. This one just sat there, silent and self-contained.

I tried to remember if I'd seen Dan Vargas working with this particular piece during the day. The camera angles didn't give me a perfect view of every booth, and I'd been focused on monitoring the loading dock and main entrances while vendors packed up. But something this distinctive should have caught my attention. The glass was spotless.

No fingerprints or smudges from curious Expo attendees. Either it was brand new or someone had cleaned it recently. The printed card looked fresh too, with crisp edges. No coffee stains or fold marks. I reached for my radio to call it in.

Procedure for any equipment left behind after closing. Luna would want to know about it, and Kenny would need the information for his morning report. Simple enough. That's when the screen flickered on. White text appeared against a black background.

Clean font, perfectly centered, Scanning complete. Profile matched, standby for extraction. I stopped mid reach for my radio and stared at the display. The text didn't scroll or fade, just sat there like a computer waiting for the next command. The device was running, operating, doing something, and it knew I was here.

I stepped back from the booth. That was when every single overhead light in the hall went out at once. Not like a power failure where they flicker first, just instant darkness. The only light left came from those red emergency exit signs scattered around the walls, casting everything in this weird Crimson glow that made the empty booths look like some kind of horror movie set.

I clicked on my flashlight and the beam felt pathetic, like holding a birthday candle in a cave. The silence lasted maybe 3 seconds. Then I heard this mechanical sound coming from somewhere behind the booth rows whirring like those little servo motors they use in remote control cars, except bigger. Way bigger. I turned my flashlight toward the sound, but couldn't see anything past the first row of abandoned booths.

Just shadows and that red emergency lighting, making everything look distorted. The whirring got louder, and I started picking up this clicking noise underneath it. Rhythmic, purposeful, like someone was walking around back there in high heels, except the timing was too regular, too precise. Click, click, click. That's when I figured it was time to leave.

I ran toward the north exit. My boots hammered against the polished concrete, and the sound echoed off the walls like gunshots. Behind me, the whirring intensified, getting closer. The clicking picked up speed, too, matching my pace like it was keeping time with my footsteps. I'd done this route probably 1000 times during my three years here.

Straight shot from the main hall to the north exit, maybe 50 yards total. Usually took me about 30 seconds walking normal speed. I covered it in maybe 10. I slammed into the exit door full speed and bounced off like I'd hit a brick wall. The door didn't budget, not even a little.

These were emergency exits with push bars that were supposed to open no matter what, even during lockdown fire code. But when I threw my whole weight against the bar, nothing happened. The magnetic locks had engaged. I fumble for my key card. My hands were shaking a little, which annoyed me.

I've been doing security for three years and never panicked over anything, but I couldn't shake the feeling that whatever was making those sounds was getting closer. I swiped the card through the reader. Red light access denied. I tried it again. Same thing.

The little LED just kept blinking red like it was laughing at me. That's when my radio crackled to life. Static first, then this voice I'd never heard before. Clinical professional. Like those automated phone messages from your doctor's office, except somehow worse.

The Riverside Convention Center has been selected as a collection site, the voice said. No emotion, no inflection, just stating facts. All security protocols have been overridden. Please remain calm during the extraction process. I stared at the radio clip to my belt.

Kenny had never mentioned anything about extraction processes. Luna definitely hadn't. This wasn't part of any protocol I knew about. The voice kept going. Subject identification.

Complete profile assessment. Unmarried male, age 22. No close family connections. Employment history indicates social isolation patterns. Minimal digital footprint.

Qualified for low impact extraction. My blood went cold. That was me. All of it, down to details I'd never told anyone here. Cooperation will minimize processing time, the voice continued.

Resistance will not affect the outcome. I ripped the radio off my belt and threw it against the wall as hard as I could. It exploded into plastic pieces that scattered across the floor behind me. The clicking was getting faster. I sprinted toward the emergency stairwell on the east side of the building.

My flashlight beam bounced wildly as I ran, throwing crazy shadows across the empty booths. The clicking followed me, keeping pace. Whatever was making that sound, it wasn't having any trouble navigating in the dark. My flashlight beam caught it moving between the rows of booths. That's when I knew I was completely screwed.

The thing had legs. Too many legs. Metal ones that bent it. Joints that shouldn't exist, like someone took a spider and rebuilt it out of surgical steel. Each limb moved with this horrible accuracy, placing itself exactly where it needed to go without any wasted motion.

The clicking wasn't random noise, it was footsteps. A lot of them. I'd seen enough. I spun around and ran for the stairwell door, hitting it with my shoulder at full speed. The crash bar gave way and I stumbled into the concrete shaft, catching myself on the handrail.

The sound echoed up through five floors of empty space, three steps at a time. That was the only way I was getting out of this. My legs burned after the first flight, but I kept pushing. The handrail was that cold metal that sticks to your palm when you grip it too tight. I could taste copper in my mouth, probably bit my tongue when I hit the door behind me.

The clicking started up the stairs. It wasn't trying to be quiet anymore. The sound bounced off every surface in the stairwell, getting louder and faster with each second. Whatever that thing was, it climbed better than I did. A lot better.

I reached the 2nd floor landing and shoved through the door into the administrative hallway. Fluorescent lights hummed overhead, casting that sick yellow glow. You get an office buildings after hours. The fire alarm pole station was mounted on the wall about 20 feet down the hall. Red metal box with a white handle.

I started toward it, then I stopped. Fire alarm meant fire department. Fire department meant people showing up to help. But what if they couldn't get in either? What if whatever it locked down the building kept them out too?

I'd be standing here waiting for help that couldn't reach me while that thing finished climbing the stairs. Plus, there was something else, something I've been walking past all week without really thinking about it. Booth 63. I'd done 7 circuits past that booth every single night for four nights straight. Kaylee Richmond had been working there Tuesday and Wednesday, setting up cardiac monitoring equipment and emergency response gear.

She'd worn a blue polo with Med tech solutions embroidered on the pocket. Always had her hair in a ponytail. Always said evening when I walked by on my rounds. She'd been packing up Wednesday night when I did my 9:00 patrol. Most of her equipment was already in boxes, but she'd left the big display items for Thursday morning pickup.

Said the company van wasn't coming until after the Expo closed. If she'd left anything behind, anything that could help. The clicking reached the 2nd floor. I turned around and ran for the main stairs, taking them four at a time. Going down, my flashlight beam bounced all over the place.

The clicking was right behind me now, maybe 10 seconds back, close enough that I could hear individual metal impacts on the concrete steps. I hit the main floor and sprinted across the lobby toward the exhibition hall. My key card was still clipped to my belt, swinging with each step. The hall doors were propped open from when the cleaning crew had finished.

I didn't slow down. The emergency lighting cast weird shadows between the booth rows. Everything looked different in red light. Booth numbers were harder to read. I counted as I ran 585960 63 was in the third row, back against the N wall.

The defibrillator was exactly where I remembered it, mounted on a white metal bracket attached to the back wall of the booth, about chest height. It looked like the ones they have in office buildings and airports. Yellow plastic case with a digital readout screen and two square pads connected by coiled cables. A small placard underneath.

Red demonstration unit, Philips heart start FRX. The power light was green. I yanked the defibrillator off its bracket. The whole thing came down with these power cords trailing behind it like some kind of medical octopus. The mounting screws probably weren't that tight to begin with.

Kaylee had been packing everything else up anyway. That's when I saw it. The thing stepped out from between booth 61 and 62. Not walked, stepped like it was being careful about where it put its feet. Which was weird because it had maybe 8 of them.

I've been calling it a spider in my head, but up close it looked more like someone had built a really expensive robot and then decided to make it as creepy as possible. All black carbon fiber and these sensor things that looked like camera lenses. The legs were thin, but they moved with this mechanical certainty that made my skin crawl, like it knew exactly where it was going and how long it would take to get there.

The clicking sound was definitely its feet hitting the floor. Each step sounded like someone tapping a pen against a metal desk. Tap, tap, tap, tap. But faster now, more urgent. It moved toward me, and I figured that was it.

I was done. But I had this defibrillator in my hands and nothing else to work with. The thing lunged forward, just launched itself at me like it was spring loaded. I swung the defibrillator like a baseball bat connected right with what looked like its head, this cluster of sensors and camera lenses all grouped together in the center of its body.

The impact travelled up my arms and into my shoulders, felt like hitting a brick wall with a sledgehammer. My whole body shook, but the thing staggered. Its legs went all wrong, like someone had cut half the wires in a computer. It tried to keep moving forward, but one leg went left while another went right.

The clicking turned into this irregular stuttering sound. I swung again. This time I aimed for the same spot. The sensor cluster figured that was probably crucial. The defibrillator made this horrible crunching sound when it hit, like stepping on a calculator.

The thing's movements got even more erratic. It's spun in 1/2 circle and crashed into the side of booth 62. One of its legs got tangled up in an extension cord someone had left behind. I kept swinging again and again. The defibrillator was heavier than I thought it would be.

My arm started burning after the third hit. But every time I connected, the thing got more confused, more broken. Something inside it started sparking, little blue flashes, like when you unplug something while it's still running. The clicking got slower, more scattered. Then it stopped.

The thing just collapsed, folded up on itself like a broken umbrella. Its legs twitched a few times and then went still. One of the sensor lenses had cracked and was leaking some kind of clear fluid onto the floor. That's when all the lights came back on. The overhead fluorescence flickered once and then blazed up to full brightness.

After 20 minutes of red emergency lighting, it felt like staring directly into the sun. I had to blink a bunch of times before I could see properly again. I was standing there, breathing hard with the defibrillator hanging from my grip. The power cords were wrapped around my left arm. My shoulders ached from the impacts, and I could taste blood where I'd bitten my tongue.

The thing on the floor looked smaller now that I could see it clearly. Still creepy as hell, but smaller, like a big mechanical crab that someone had stepped on. My radio crackled. I'd forgotten about the radio, thrown it against the wall upstairs and broken it. But there was another one clipped to the thing's body, a small black box with a green LED that was blinking slowly.

The same clinical voice came through clear as before, but there was something different about the tone, like someone who just gotten mildly annoying. News subject has damaged collection unit beyond repair. The voice said extraction window has closed due to extended processing time. Data collection from Booth 47's biometric scanner was sufficient for profile completion.

Collection site will be relocated to alternative facility. I stared at the radio. Booth 47, that display case I'd found earlier, the one with the medical device inside biometric scanner, collected facial recognition data, thermal signatures and behavioral patterns during subjects routine patrol activities over the past 72 hours. Thank you for your cooperation. The radio went silent.

The green LED stopped blinking. I dropped the defibrillator. It hit the floor with a heavy thud, and the remaining power cords coiled around it like dead snakes. That was it. Whatever had been happening was over.

The building was locked down, the lights were back on. There was a broken robot on the floor, and I was still alive. I figured I should probably call someone. Luna Bush, maybe, or the police, But what was I going to say? That a medical device had tried to scan me and then sent a robot to collect me for some kind of extraction process?

Nobody was going to believe that. I walked back toward the security desk. My legs felt shaky and I had to stop twice to catch my breath. The building felt normal again, just empty and quiet like it always was during night shift. But I kept thinking about what the voice had said.

Alternative facility? How many other places had these scanner things? How many other night security guards were walking around empty buildings right now, getting profiled and measured for extraction? 3 weeks later I was working at Daily Grind on Maple Street, day shift, 7:00 in the morning until 3:00 in the afternoon, making coffee and cleaning tables and dealing with customers who complained about everything.

I'd quit the Convention Center the next day, told Luna I was moving out of town for family reasons. She didn't ask many questions, probably figured I'd found something that paid better than $15.00 an hour. The coffee shop was fine, busy enough that I was never alone. Windows on three sides so I could see everything coming and going.

The manager was this older woman named Beth who talked too much but made sure everyone got their breaks on time. I refused to work nights anywhere, turned down three jobs that would have paid more just because they wanted someone for evening or overnight shifts. Beth asked about it once and I told her I had insomnia, which was sort of true.

I wasn't sleeping great anyway, but the real reason was that I couldn't handle being alone in buildings after dark. Even thinking about it made my chest tight. I'd walk past the Convention Center sometimes on my way to work and see Kenny's car in the parking lot. New night security guy. Probably some other isolated 20 something with no family and minimal social connections.

I wondered how many people had already been successfully extracted, how many empty apartments were sitting around the city because their occupants had just disappeared one night during a routine shift. People like me, people nobody would miss. For a while, the voice had called it low impact extraction. That part stuck with me, like they done the math and figured out exactly who they could take without anyone noticing.

I kept wondering if I just been lucky if that defibrillator had actually been enough to stop whatever was supposed to happen to me, or if they just moved on to someone easier, someone who wouldn't fight back with medical equipment. That's the part that bugged me most, not knowing how many other buildings had those scanner things, how many other night workers were getting profiled and measured while they walked their rounds, thinking they were safe and alone just doing their jobs while something invisible collected data and waited for the right moment to send in the collection units.

I figured I'd probably never know for sure, but I wasn't going to be alone in an empty building after dark ever again, that was for certain.
