Sealed Chamber Within the Rani's Headquarters

The chamber presents itself as a compact, windowless enclosure of reinforced durasteel and alloy, its metallic surfaces dull under the harsh overhead lights. The air hums with the low thrum of failing containment fields, their blue diagnostics flickering in jagged pulses across the walls like dying stars. The seamless door seals with a hydraulic hiss as the Doctor steps inside, the sudden quiet broken only by the rhythmic tick of cooling systems struggling against the artificial warmth. A single workstation glows with data streams in violet and crimson, mapping the asteroid's trajectory with ominous precision. The floor presses slightly underfoot, betraying the chamber's secondary role as an interrogation platform—its floor plating adjusting subtly as unseen mechanisms weigh the occupant's stability. The space feels compressed yet boundless, as if the walls themselves monitor every breath.
