Ha! Thank you for talking! You gave me another idea :)

Normally vampires cannot procreate, the change through death makes them sterile but the 'royals', the aristocrats of the vampire society and a certain coven - a series of families - in New York City, were born vampires. They are the strongest and most heavily gifted, though there's only one family that is really pure of their blood and heritage. These are the descendants of vampires who became from binging on the blood of mortals and immortals alike. There are few families like this, that remain so pure and thus are able to control those beneath them. the aristocrats are of the same blood and may birth their young as well, though these are ones who had a touch of human in them, enough to make them less. Below these are those who have been turned - every vampire not of these families - was turned, less strong, not as fast and easier to kill.
