|Ships are invisible|
Your ships are invisible to everyone except yourself. This includes your ships on any planets, totals in the mothership, in alliances, and in the warp. It also includes your colony counter - it is invisible to everyone except you.
The specter of being driven from their ancestral homelands by stronger beings caused the Ghosts to evolve a spirit of secret defiance towards all who would dare encounter them. Haunted by the lack of a strong physical presence, the Ghosts took to lingering in the shade and perfecting the art of being ever unobtrusive. Some would spook at the slightest provocation but that strain slowly died out. Successive generations became as phantoms to the unobservant, and in time the Ghosts and their threats to dominate the Cosmos were all but invisible to mere mortals.
