Iron Lung plot
"They will get their execution... I will get my freedom."
The stars and planets have vanished. Only individuals aboard space stations or starships remain. After decades of decay and crumbling infrastructure, the Consolidation of Iron has made a discovery on a barren moon called AT-5. Hoping to discover vital resources, they immediately launch an expedition. A submarine is constructed and a convict is welded inside. Due to the pressure and depth of the ocean, the forward viewing port is sheathed in metal. If they succeed, they earn their freedom. If not, another will follow. This will be the 13th expedition.
