From the introduction:
Welcome to the Post Disaster timeline.
Three hundred years ago, the world was ravaged by what has come to be known as the Calamity War. Caused by rampant technological development and the rapid expansionism into space of the world powers, it plunged the world into chaos and death. In it’s wake, only the organization Gjallarhorn has lasted to the modern day, a corrupt, self-appointed peacekeeping force that exploits the colonies on mars and in space mercilessly. Not to say that everyone else isn’t corrupt as well.
It’s a world of child exploitation, few morals and crushing cynicism.
Basically life sucks and you’re probably going to die in a ditch.
