Sulpicia

Sulpicia is a vampire and Aro's wife. She is a member of the Volturi coven, and lives in Volterra, Italy, spending most of her time with Caius's wife, Athenodora. Sulpicia was a lovely young orphan girl, chosen and created by Aro, as she was what Aro had in mind for a mate. After successfully courting her, she agreed to be transformed into a vampire and become Aro's wife; she remains totally devoted and loyal to him.

Sulpicia is not featured heavily in the series. She only appears at the end of Breaking Dawn, but does not say anything. In the book, during the confrontation between the Volturi and the Cullens, there appeared to be "two hooded figures, definitely women, flanked by two hulking bodyguards". These were Sulpicia and Athenodora. They are important to the ancients, and therefore are heavily protected. It`s not often that the wives are leaving the tower, not even during the southern rebellion, when the Romanians tried to overthrow them or when the Volturi were hunting the immortal children, like Jasper said in Breaking Dawn.

Aro
Aro is Sulpicia's mate and creator. Little is revealed about their relationship, however it can be said that they are very loyal to one another. After Didyme's death, Caius and Aro realized that they could face the same devastating blow; they then heavily guarded their wives, hardly ever letting them leave their tower.

After Caius and Marcus had found their romantic attachments, Aro decided to find his own, although rather than finding his other half in another vampire Aro decided to create his own instead. He soon found what he was looking for in Sulpicia. After her transformation, they married and have been together ever since. The Romanians recognizing the wives in Breaking Dawn suggest they were together before the Volturi came to power.

Athenodora
Athenodora is Caius's wife and Sulpicia's company in the Volterra tower. She and Sulpicia are both guarded heavily by powerful guards. Corin's gift, however, keeps them content and even happy while in their confinement.
