Spaceship Observation Deck

Glass and metal walls curve around the space in deep reds and blues, the tinted viewscreens casting shifting venous light across polished surfaces. Tiny reflections of distant nebulae ripple over the hull as the ship quivers under the strain of its failing systems. There are no visible controls or furniture—just the walls, the windows, and a sense of liminal transit between interior and exterior. When Biroc leads the Doctor here the atmosphere tightens into stillness; no hum of machinery breaks the silence, no crew pass through, and when the TARDIS dematerializes the space seems emptier, as if it were always a threshold rather than a destination.
