Charlton 4

Planet Name:  Charlton 4 Location:  Charlton System Description:  A small rocky planet with a toxic atmosphere of 83% Carbon Dioxide, 10% Oxygen, and 6% Nitrogen. The planet is famed for the many terraces that look as though they have been 'carved' into rock faces. An extensive network of caves also exists. While many people insist that these structures are not natural and must have been made by intelligent lifeforms, there is no actual evidence of this. In fact there is no evidence of life ever having existed on the planet besides these strange rock formations. When a nearby inhabited planet suffered a catastrophe, the caves were sealed off from the atmosphere and converted to serve as an emergency refugee camp. Many of the survivors still live there today, having converted the caves and tunnels into a vast underground city.
