Good stuff. Oh there is a chance I might actually have that condition myself referenced. Although it works to my benefit as as it turns out I'm transgendered. So it works.
But one fear I have, as over the course of writing these side stories, it seems like I' moved further and further away from science fiction ( when I had moved away from horror ), and now my work is in this weird place, because while there are vampires ( clinical vampirism in this case ) it doesn't really effect the plot in the same way it does in say ... Underworld or Blade Of The Immortal.
It basically is just used to mean a genetic predisposition to because state executioners, who are paradoxically an underclass and a form of nobility.
But a lot of them end up becoming homeless rejecting that lifestyle, and instead being skilled with social engineering as an aid to computer hacker friends.
