Caius is a vampire, one of the three ancient leaders of the Volturi, who are based in Volterra, Italy, and who, according to Edward Cullen, lead a very civilized lifestyle. Caius has a wife named Athenodora, who lives a very retired life in Volterra. He is the most ruthless of all three leaders. Caius was born around 1300 BC, and at some point became a vampire. He was born at least a century before Aro and was transformed into a vampire in his late 40s.
