Freezing Storeroom Interior

A cramped, frigid storeroom with peeling walls and dim emergency lighting, its air thick with the metallic tang of failing machinery. Metal shelves sag under layers of dust, their surfaces crusted with frost that reflects the sparse illumination. A single unshuttered window high in the far wall lets in a narrow streak of dim light, barely piercing the gloom. The Doctor sits on a cold metal bench, his breath forming visible clouds as Flast reveals the Cryons' last stand against the Cybermen's temporal conquest.
