In this story, there are various classifications of vampires spread throughout the world. The two main groups are sport vamps and humane vamps, much like meat eaters and vegans. Sport vamps primarily feed on live humans, hunting them for the fun of the challenge. Humane vamps prefer not to kill for food and look to alternative sources.
Vampires are more docile and less fiendish than in the past. They prefer to stay in their own nation and have farms of reusable live humans, called Fractions, as a food supply. They'll occasionally go out for a sport kill, but the majority of time the vamps wait for the humans to come to them. It's easier and less suspicious. Humans think they are joining a vampire themed cult. Since cults have the reputation of keeping people away from loved ones, no one suspects what is really happening. Vampires like this concept. In their eyes they are aiding humanity.
Through the centuries, vampires have made major contributions to society and science. Many scientific breakthroughs have been the work of vamps, as they are able to conduct more trials and analyze outcomes over a longer period of time than humans. When the breakthrough occurs, vamp scientists let humans take the credit to keep their vamp identity unknown.
Similarly, society has benefited from vamps involved in everything from the politics to art. Vamps tend to prefer parties to battle, but there are those few who thrive on war and conflict.
