Blue Light Chamber

The windowless blue-light chamber functions as a temporal stasis prison, its red brick walls absorbing the pulsating glow that progressively strips Sarah's autonomy. The humming device's low-frequency thrum vibrates through the floorboards, synchronizing with the flickering blue to enforce immobility.
