Vampires can be human, creature or mechanical in nature. The commonality between them is that they trick haematurgists into blood-bonding with the vampire, thereby granting them another source of magic. Such bonds can be forged through coercion, hypnosis, neural manipulation, pheromones and hormones, and many more ways. Fundamentally, each of these methods causes a person to part with blood they would not otherwise let out of their veins. To practice vampirism is to be in breach of the victim's human rights, as per an article in the Bloodwrit.
