A Triumvirate is formed when a vampire, a human, and a shapeshifter share their essences with each other and bond in the manner a master vampire bonds with a human servant. They will share each other's powers, thoughts, and personalities. It takes a degree of control to be able to adapt to the power of a triumvirate. Normally, triumvirates are formed by a master vampire, its human servant, and its animal to call. However, it is not always the case. In extremely rare circumstances a powerful human can bond a non-master vampire and their own animal to call (should they have one) to themselves. Despite all of this, triumvirates in any shape are still quite rare amongst vampires as they either prefer just a human servant, do not have an animal to call, or are not powerful enough to do this.
