Firefly – Culture Reviews & Race Rating
It looks like there are only two that matter, and boy is there a big difference!
More an institution than a Race: An oppressive regime that manages the wealthy worlds but tends to leave the frontier planets to fend for themselves.
Humans with no trace of humanity: The scariest villains! A bunch of raping, malevolent, killers that like to wear clothing made of skin!
