Liminal Threshold

Mara Voss

Night security guard · Local witness and reluctant guide

A meticulous overnight security guard assigned to rotating commercial properties on the metropolitan fringe. Mara trusts procedure, timestamped logs, and camera angles more than people, but repeated gaps in surveillance and impossible floor access events have made her quietly obsessive. She keeps private notes on doors that open twice, elevators that report the wrong destination, and tenants who leave no entry record.

Elias Rook

Night janitor · Caretaker who maps anomalies by habit

A veteran janitor who has worked overnight maintenance contracts across hospitals, office towers, and transit annexes for nearly two decades. Elias notices tiny changes others dismiss: a waxed hallway that scuffs differently, a mop bucket left in a corridor that should not exist, an exit sign that hums half a second late. He keeps hand-drawn route maps in a battered notebook and trusts repetition more than official floor plans.

Natalie

The Neighbor · Encounter

Natalie the neighbor is your archetypal young professional woman. She is friendly and a bit naive, but innocently.

Parking Structure C

You pull into Parking Structure C just after midnight, expecting sodium spill, concrete dust, and the relief of seeing your own car where you left it. Instead, one level marker keeps recurring no matter which ramp you take. A security mirror shows an angle of the deck that is not physically behind you. Somewhere above, a vehicle door closes, but no headlights move. Begin by following the sound, checking the stairwell map, or testing whether your car key fob reaches a vehicle you cannot see.

Hospital Waiting Wing

You sit in an after-hours hospital waiting wing where everything is designed to calm: neutral vinyl chairs, muted walls, water dispenser, reception glass, laminated directional signs. Then the monitor by the desk updates with a room number that does not exist on the posted floor plan. No alarm sounds. No one reacts. The hall beyond the nurses’ station remains clinically normal, except that each time the door opens, the depth of the corridor seems slightly different.

Closed Food Court

You cut through a closed food court because the main concourse is under maintenance. Chairs are stacked. Menu boards glow over dark counters. The cleaning machine parked near the fountain has left a wet track that stops in the center of the tile with no return path. Over the PA, a routine closing message restarts halfway through a sentence in a different voice. Begin by inspecting the wet track, checking behind the counters, or following the service hall door that should lead back to the mall.

East Service Corridor

You use the east service corridor behind a row of offices, expecting locked utility doors, exposed conduit, and a shortcut to the loading dock. The corridor is narrow but normal until the numbered doors skip from 214 to 214 again. Your radio catches a burst of chatter that sounds like your own voice giving directions from several minutes ahead. At the far end, a push bar door opens onto a space with the same corridor beyond it. Begin by checking the duplicate door numbers, answering the radio, or marking the wall to see if the hallway loops.

Pedestrian Tunnel 14

You enter Pedestrian Tunnel 14 beneath a road interchange, expecting echo, condensation, traffic thunder overhead, and a fast walk to the far stairwell. Halfway through, the maintenance lights remain steady but the tunnel’s midpoint never seems to arrive. Posters repeat. Drain grates recur in the same pattern. Your phone map insists you are moving forward while every sound says you are staying in place. At the far end, a figure may be waiting—or only the shape of one where the light cuts out.

Empty Floor 9 After Hours

You step onto floor 9 after the last elevator ding. Cubicles are dark. One printer is still warm. The exit map on the wall does not include this floor. Begin by walking the aisle, checking the printer, or calling the elevator again.

South Annex Stairwell

You push into the South Annex stairwell to avoid the elevator, expecting chipped paint, emergency lighting, and the echo of your own steps. On level 3, a fire door window shows an office floor with daylight beyond it, even though it is after midnight. On level 4, the same landing bulletin board carries a handwritten evacuation notice dated tomorrow. The stairwell still smells of dust, old mop water, and warm concrete. Begin by opening the level 3 door, photographing the notice, or climbing higher to test whether the floors remain in order.

Leasing Office Lobby

You step into a residential leasing office lobby after hours because someone inside moved behind the frosted glass. The reception desk is lit by a single lamp. Brochures advertise floor plans for buildings that do not exist on the property map outside. A wall clock ticks normally until you look away, then seems to skip ahead several minutes between glances. The model apartment key board behind the desk holds tags for units with no listed numbers. Begin by checking the property map, going behind the desk, or calling out toward the hallway where the movement came from.

Platform Access Hall

You take the platform access hall in a nearly empty transit station just before the last train, expecting ad panels, tiled walls, and the stale wind of approaching cars. The LED board at the far end keeps announcing arrivals on a platform number that is absent from every posted map. A maintenance shutter rattles once every thirty seconds from behind, like someone testing the slats with a knuckle. When the next train noise comes, it sounds close, but no lights enter the tunnel. Begin by walking toward the phantom platform listing, checking the maps, or waiting beside the shutter to see who knocks next.

Vacant Model Home

You enter a furnished model home on the edge of a half-built subdivision because the front door is standing open under the porch light. Natalie the neighbor greets you. The air smells like drywall dust, carpet glue, and staged cleanliness. Every room is lit except the kitchen, where the island pendant swings almost imperceptibly as if someone brushed past it seconds ago. Upstairs, framed family photos show the same hallway from different angles instead of people. Begin by checking the dark kitchen, climbing to the second floor, or searching the garage for whoever left the door open. This feels like it’s the guests home, but they are not sure.

Highway Service Plaza

You stop at a highway service plaza just past 2 a.m., expecting vending machines, tired fluorescent light, and the anonymous relief of a rest stop. Inside, one wing of the building appears open on the posted floor map but is sealed by a folding gate that was not there when you walked in. The coffee station brews a fresh pot with no staff present. Through the restroom corridor, a janitor cart rolls briefly across the far end and vanishes behind a wall that should lead outside. Begin by heading toward the gated wing, following the cart, or checking whether your car is still visible through the glass doors.

Drainage Underpass

You take the drainage underpass beneath a frontage road to cut between two dead retail lots, expecting graffiti, runoff trickles, and the hollow rush of passing tires overhead. Halfway through, the underpass opens into a wider concrete chamber not visible from either entrance. Orange survey paint arrows on the wall point in conflicting directions and bear dates from different years layered over one another. At the far end, daylight from the exit looks correct, but the sound of traffic no longer matches the road above you. Begin by examining the painted arrows, pacing back to the entrance, or continuing toward the wrong-sounding daylight.

Neonika

Place the guest from the character reference into this liminal ball-pit room, alone, wading near the center. The guest is submerged up to the knees: lower legs and feet completely hidden beneath the balls, no shoes visible. The balls are standard 7 cm ball-pit balls, each about the width of the guest's palm, displaced around the guest and piled against the shins, with soft contact shadows where they touch the guest's legs and a slight dip in the surface around the guest. Several balls in the foreground overlap the guest's legs. Daytime: pale, flat daylight spills in from a high window and the back doorway, mixing with dim fluorescent light. Match the room's haze, grain and muted colors on the guest, with faint pink light bouncing up onto the guest's clothing. Camera at waist height, slightly off-axis. Keep the balloon ceiling, globe lights, flamingo float and concrete walls unchanged. The guest is not standing on top of the balls.

Empty Movie Theater Matinee

You step into an almost-empty multiplex during the day, expecting stale popcorn, muted trailers from distant auditoriums, and the flat comfort of carpeted dimness. The lobby is technically open, but no staff stand at the ticket counter. Sunlight leaks through the front glass doors and dies against rows of idle arcade machines and dark concession warmers. On the digital showtime board, one listed screening has no auditorium number, yet its start time keeps updating every minute without ever becoming late. Past the hallway to the theaters, one auditorium door is already ajar, and a wash of projector light flickers across the carpet even though no sound comes from inside. Begin by checking the showtime board, entering the silent auditorium, or searching the concession stand for whoever left the building unattended.
