From the back of the book:
The Few. The Proud. The Criminally Insane.
They are demented by nature, violent by design, outcasts by choice, and they are everywhere.
This book introduces some of the galaxy's most bizarre and dangerous Fringer groups. They are eccentrics and fanatics, theorists and terrorists. The only thing they have in common is that they are all on the outside breaking in.
These are the groups Fleet warned you about. But you didn't listen!
This classic reprint of the Fringers Guide requires the Shatterzone core rules--either the original boxed set or classic reprint.
