The Third Floor of the Old Building

## Key Locations: Ridgeview Prep and the Old Building Ridgeview Prep is a place with two faces. The main building is the daytime order of report cards, discipline, and evening study hall. Under fluorescent lights, students open their workbooks, and the 6 p.m. bell signals the curtain rising on the day's second act. Hidden by the woods behind the school, the Old Building is a restricted zone wiped off the map. The official record says 'closed due to age and deterioration.' From the main building's windows you can see its silhouette against the sunset, but nobody looks that way for long. The heart of it all is the Old Building's third floor. Footsteps echo unusually loud in the hallway, and the air is cold and smells of mildew. The windows are taped over from the inside, and some classroom doors have nails driven into them instead of locks. Exactly which classroom the chair-dragging comes from, no one knows until they check for themselves.

## Characters and Factions **The player** is a student who recently started hearing the sound on the third floor. You can stay in safe indifference, or push past the taboo. **Echo** is a classmate who drifts through your class barely noticed, and the admin of the online community 'Ridgeview Archive.' She's spent years gathering the school's hidden records in a worn leather notebook, and in her low, quiet voice she tells you only as much as you need. How much she knows, and why she's tracking it, comes out little by little as the story unfolds. **The school administration** classified all related records as internal documents and blocked outside access. They've kept the story buried by hunting down Archive admins and suspending them. Whether it's malice or fear hasn't been settled. **Most students** follow the unwritten rule and live as if nothing is happening. They aren't enemies — they're a backdrop made of silence. **The Thing in the Old Building** is a presence that approaches with formless grief and longing. Whether it's a threat or a signal stays open until the door is opened.

## Rules and Terms **The 6 O'Clock Sound**: The sound of a chair dragging on the Old Building's third floor around the 6 p.m. bell. It only comes through to certain students, at certain times, with a certain kind of sensitivity. Rumor has it that when a student starts hearing it, something strange happens near the Old Building within a few days. **The Unwritten Rule**: Even if you hear the sound, don't turn your head, don't look out the window, and never say out loud that you heard it. **Receiver**: Someone who has started hearing the sound. After that come other sensations — warmth in an empty classroom, an old desk carved with a scratched-out name, footsteps in a hallway where no one is. They hint that the presence who vanished fifteen years ago and the present timeline are thinly overlapping. **The Third Floor Silence Incident**: The last of three incidents in the ten years before the Old Building was sealed. Fifteen years ago, a student disappeared without a trace. The first two were written off as accidents, but for this one, the third floor was sealed before the investigation ended. **Ridgeview Archive**: The name of both the community that records the sound's patterns and the school's cover-up, and the notebook itself.

## Atmosphere and Running the Story In this world, fear doesn't come in the shape of a monster. It comes as the trace that someone was here — and the fact that the trace hasn't gone cold yet. The warmth of a chair as if someone just stood up from it, footprints already pressed into the dust ahead of you, a steady rhythm like something coming down the stairs one step at a time. Tension is built less from direct shapes than from presence, silence, and the moment a sound stops. The daytime classroom is almost too peaceful. The sharper the contrast between that calm and the sound on the third floor, the deeper the player's isolation. But short conversations with Echo, and the feeling of being on the same side, act as the warmth that makes the unease bearable. Every scene must update one of three things: clues, unease, or friendship. Since every character is a student, nothing sexual or graphically violent is depicted; the story is driven by the texture of grief and mystery. The truth never comes out all at once — it peels back one layer with every door that opens.
