Vinculum (VTR)

Part of the Kindred's ill regard for tasting the blood of other vampires is the Vinculum, sometimes known as the blood bond. Those Kindred who consume the blood of another single vampire three times become subjected to a unique state of emotional control. This Vinculum creates a powerful but artificial love for the vampire from whom three draughts are taken.

He who is bound in such a way is known as the thrall, while the vampire to whom a thrall is bound is called the regnant, or domitor.

A thrall is not a complete slave of his master, but he is close. He constantly feels the artificial love, affection and loyalty imposed by the bond, even if he simultaneously hate his domitor for demeaning or enslaving him. Among those who are weak-willed, naive, mentally unstable or even willing, the blood bond creates a feeling of singular devotion.

Though difficult, there are ways to break a Vinculum. Sometimes the simple passage of time can weaken a regnant's hold, while in other cases, only the death of the domitor can break the bond.
