The descendants in the world of vampires were depleting, fewer and fewer were born with a hint of pure blood, each time needing more blood from their leaders to maintain their powers.
Some believed that in a few decades, the last pure-blood descendant would be born, no more, and soon the vampire race would cease to exist. They could not survive without the blood of descendants. Even if they create more vampires from humans, in the end, they will turn into dust or monsters in less than two centuries.
That was the greatest fear of the seven clans, to disappear from the face of the earth. This world that belonged to them now will be purely human. They cannot allow it.
They needed purebloods, they needed the pureblood vampire to engender descendants. They would treat this pureblood as a king or queen, but he would truly be a prisoner, provider of offspring, of life and hope to the vampires. They had to be the first to capture it, even if they had to force him.
