The Ghost Bloods

Do you have to be born with some aspect, some genetic marker, some spiritual dione in order to be part of the ghost bloods or any of these other groups? I like it. Its an interesting thought. Ghosts are sort of misty in that ephemeral type of way. Blood sort of connoting something that you're born with, something natural or innate. So, ii get the parallel. Should we jump over to the main rival, the sons of honor? Oh yes. They are fully recharin.
