PBN was set in Eastern Europe of an Earthlike planet in the 16th century. It featured the character of Silver along with several other vampires, a nun called Sister Chastity and assorted cultists and vampire hunters.
PBN was never finished, though a rough ending was plotted.
A group of vampires was living in a castle. They were generally good people as vampires go, and in particular were non-lethal feeders: they didn't consume enough blood to kill their victims.
However, people were turning up dead and drained of all their blood, so naturally the vampires were blamed.
Things came to a head when the local baron's daughter went missing.
It turned out that the exsanguination-happy culprits were actually cult members, who were the 16th century equivalent of obsessed stalker vampire-fanboys, and thought that drinking enough blood with the right rituals would make the vampires accept them as their own. Or something.
The vampires dealt with this cult in a satisfyingly violent manner, but the locals were still not impressed. The group was not welcome in those parts again, and the main part of it left together for a new happy hunting ground. (Silver slivered off from the group sometime later.)
As a footnote, it's likely that more vampires moved into the area now it had an ideal vacant don't-go-near-the-castle and no local predators. This goes to show that you can't win if you're edible.
