Blood Bond
A Blood Bond, also known as a Blood Oath, the Coeur-Vrai or the Coils of Apep[1], is a supernatural link of fidelity and dependency of one individual (the thrall) on a vampire (the regnant), created and maintained by the repeated consumption of vitae.
Blood Bond: After accepting blood from a vampire three times, one becomes under the supernatural influence or mastery of the supplying vampire.
Virtually anyone can be enthralled through it, making the blood bond one of the most powerful vampiric tools. The strength of this link varies based on several factors, but it is incredibly difficult to break and likely will have many lasting effects on the thrall.
Someone becomes involved in a blood bond by drinking the vitae of the same Cainite on several occasions not excessively spaced in time. After the first sip of blood, the thrall begins to develop strong feelings for the regnant, whether love or hate, though they are still free to act as they choose. Those in a one-drink bond may unconsciously seek out the regnant, seemingly accidentally running into them on a frequent basis.
After the second sip, the regnant becomes a very important person to the thrall, who may go out of their way to seek the regnant's attention or please them. It becomes difficult for the thrall to do anything that would harm the regnant, and the regnant likewise finds it easier to convince the thrall of things. Though the thrall's craving for the regnant's blood increases, they still retain their free-will.
After the third sip, the blood bond is complete. The thrall is now subject to the regnant completely and loves them as much as they are capable of loving anyone. The regnant is the most important person in the thrall's life and takes priority over all else; sufficiently weak-willed individuals will commit any act the regnant asks of them. Furthermore, the regnant may command the thrall with Dominate via voice alone. It may still be possible for the thrall to act against the regnant, but only temporarily and after an extreme effort of will.
The strength of the blood bond is not influenced by the generation of the vampire, but continual drinks do reinforce it. The bond will become weaker over time if the thrall does not drink from the regnant's blood and does not see them for a long time. However, due to the very nature of the bond, such avoidance may be extremely difficult for the thrall. The blood bond can be broken by the death of the regnant, however, the effect on the thrall is variable: some feel relieved or even joyful; others experience pain and desolation; others yet fear their independence and look for a new bond. A few may even kill themselves.
All childer begin at least one step bound to their sire, and it's normal for those that were ghouls to already be fully bound or for a fledgling vampire to be fully bound to their sire shortly after the Embrace. This was particularly common among the High Clans in the Dark Ages , when oaths of fealty to a liege were reinforced by some level of the blood bond. The Tremere have their own variation of this custom where all members of the clan are partially bound to their elders and the Tremere Inner Council of Seven. Version DifferencesEdit
In Dark Ages: Vampire the blood bond is called the blood oath, and instead of filling the thrall with feelings of love and adoration they filled with a sense of loyalty and obligation for their liege. Thus, its entirely reasonable for the thrall to strongly disagree with or even hate their liege, but they nevertheless feel bound to protect them and their interests.
In V20, the Tremere clan weakness is heightened so that Tremere vampires become blood-bound from only two draughts, with the first counting as having two draughts.
