A Soft Hum in the Wall

A tiny, rhythmic vibration stirred along the baseboard behind the armchair. I paused beneath the low table, letting the quiet settle around me before moving out toward the faint hum. Up close, there was a little rectangular box resting on the floorboards with a small amber light softly glowing on its face. I sat down and placed one paw against the casing. It felt faintly warm, pulsing with a steady, quiet rhythm like a slow breath. I stayed there beside it, watching the gentle amber light paint the wooden floor in a sleepy glow.
