The torch's firelight illuminates dirty but otherwise smooth metal walls - they’re obviously from pre-Catastrophe times. In this claustrophobic darkness I long to see the surface again, curving up and around into blue-white haze; a giant bowl around the sun.
The shaft ends in a window beneath my feet. It reveals a pure black speckled with thousands of brilliant points of light. A huge cave, surely? I decide to break through the glass.
Onwards!
