Restricted Station Corridor Stairwell

A narrow stone passage ascends between platform level and lower restricted zones, its walls lined with aged brick and discolored plaster. The staircase’s treads slope unevenly from decades of maintenance neglect, groaning underfoot as the Doctor picks his way upward. Dim emergency lighting casts long shadows that stretch toward the reactor and communications rooms at the corridor’s far end. The air thickens with the scent of damp concrete and stale ozone from failing systems, carrying just enough of the lift’s hydraulic whine to mask his approach. At the platform level, a single rust-streaked fire door hangs ajar, its hinges screaming when the Doctor nudges it open. Below, the reactor’s pulse becomes audible—a deep, rhythmic thrum that vibrates through the stonework and the soles of his boots.
