Also forget the images of abduction and ceremonial changing from human to vampire, it never happens.
Centuries ago permission had to be granted by the Grand Council before any vampire could attempt to change a human. Such was our elitist preferences. These days rules have been relaxed somewhat.
Haeyled are not created ad hoc or willy-nilly to coin a human phrase. Not all humans are cut out for being a vampire, and vampires are somewhat elitist. For any human to become vampire they must bring something of value to vampires.
In the past, vampires have sought humans for their knowledge or understanding of the world. More recently, any human who displays what vampires consider exemplary characteristics is more likely to be considered.

Other characteristics such as compassion, patience and tolerance are also valued by some vampires. This is because they enable vampires to better understand and assimilate among humans.
