Black Ghosts

All the Black Female Black Ghosts were though to have been wiped out many years ago, but I John Smith had found one and she has a job for me and my family. I am not sure what the Black Ghosts want me to do and why they want my help. Tattoos and maps may lead to untold riches. First we have to beat the raiders they are terrorizing the planets and will stop at nothing to get the riches first. Who is on our side, who can we trust and who is this slave girl Sarah really?
