The Listener in the Vent

Description

The entity is defined by acoustic evidence rather than visual proof. A rusted vent produces a tone that changes with the room, and a set of muffled breaths follows whoever carries a flashlight into the corridor.

Recovered material

Audio fragment / vent inspection log / witness note

Narrative

the vent was sealed. the sound came from inside the wall. no one looked up. no one heard it before the lights produced a second shadow. there is no direct evidence that it is a person. only that it keeps waiting for a response.
