Much like the snake and the bird, the vampire can control the will of humans through a form of hypnotic, even to the point of inducing a catatonic state and amnesia. This power explains why victims often have no memory of being attacked.
This hypnotic control can be conveyed either verbally or telepathically, depending on the power of the vampire.
Powerful vampires and Vampire Regents need only to catch the gaze of their intended victim for a few seconds, through stronger minds require more time to mesmerize.
Victims bitten by a vampire are much easier to control, requiring little - if any - concentration from the host-vampire.
