Kuppam

Kuppam was an artificial world built in Earth's orbit by the Yamoyata Company. It was a steel and glass spheroid with a stationary casing of lunar rock. The planet's hollow interior was inhabited. It boasted woodlands, rivers, hills, bridges and towns. One of the light-alloy bearings used to support the junctions between the static outer shell and the rotating interior snapped, causing the shell to be breached and to collapse. Fifty thousand five hundred ninety-five people died. (PROSE: Growing Higher)
