Athenodora is the wife of Caius and is a member of the Volturi. She lives in Volterra, Italy and rarely leaves, even during important times of vampire history, such as the hunting of the immortal children. She only appears at the end of the Breaking Dawn, but does not say anything. In the book, it is mentioned that during the confrontation between the Volturi and the Cullens, that there appeared to be "two hooded figures, definitely women, flanked by two hulking bodyguard." This was Sulpicia and Athenodora. They are important to the ancients, and therefore have to be protected.
