Classically a triumvirate is a master vampire, his human
servant and his animal to call (both given all four marks). There have been few triumvirates recorded throughout
history. Jean-Claude, Richard and Anita are so powerful individually that at first they don't need any marks, but due
to other circumstances Anita and Richard wind up with three marks. The connection of the marks increases not only
their individual powers but they've become more powerful as a team.
