Didyme

Name             : Didyme

Species           : Vampire
Perpetual Age : Unknown
Clan                : Volturi Clan

Created By     :  Aro

Hair Color       : Black
Eye Color        : Red
Skin Color       : Pale

Didyme was a vampire and Marcus' wife. She was Aro's sister, and used to be a member of the Volturi until Aro killed her. Her death greatly upset Marcus, who became apathetic afterwards. Didyme had the gift to make people happy, also known as the aura of happiness.

Early Life

Didyme was born several years after her brother Aro A decade and a half after Aro became a vampire, he personally transformed her into one; hoping she would show an extremely useful talent. However, her gift was simply to make those around her incredibly happy. This notwithstanding, Aro still planned to put such a power to use.

Because of the aura of happiness, many people fell in love with her. However, she only ever reciprocated those of Marcus, Aro's most trusted partner. The pair became incredibly happy together, and to such an end they no longer cared much about Aro's plans to gain control of the vampire world. After centuries with the Volturi, the pair made plans to leave. Aro pretended to give his blessing, and murdered Didyme so that Marcus would stay (his talent being more useful for Aro's cause).

After Didyme's death, Aro had Chelsea use her talents to force Marcus to feel loyalty to the Volturi, though he became a zombie-like being (similar to Bella in New Moon while without Edward), with no passion for anything. He never learned that Aro was behind Didyme's death. It is quite possible that Marcus' dull state is an effect of his withdrawal from Didyme's aura of happiness.

Demetri is a vampire member of the Volturi Guard with the powerfulability to track people through the tenors of their minds.

Early Life

Demetri was born in Greece and transformed by the Egyptian Coven's leader, Amun. They were very close at the time, and worked together to develop his power.

When the Volturi heard of Demetri and his powerful gift, he was offered a place in the guard, and he obliged due to Chelsea's power over emotional bonds. Ever since then, he has been the Volturi's tracker; whenever anyone tries to elude the Volturi's grasp, usually out of fear of punishment, Demetri tracks them down. As a tracker, he is significantly more talented than both James and Alistair, and known as the best tracker in the world.

Corin

Name             : Corin

Species           : Vampire
Perpetual Age : Unknown
Clan                : Volturi Clan - Guard
Created By     :  Aro

Eye Color        : Red
Skin Color       : Pale

Corin is a female vampire member of the Volturi guard, whose first appearance was in the vampire index in the back of Breaking Dawn. She was also listed as not being mated.

Early Life

Corin was created by Aro, becoming a member of the guard around the time Didyme was killed. Aro hoped that she could help Marcus recover to some degree from the loss of his wife, but when Marcus refused to accept Corin's gift to ease his pain, Aro found her gift more useful to console the Volturi wives. Corin then spent most of her time associated with the wives, and is also the reason why they never leave the tower, as mentioned in Breakin Dawn.

In the Volturi, Corin's main responsibility is to protect the wives of Aro and Caius, Athenodora and Sulpicia. However, she doesn't guard them so much as ease them into complacency while other, while more physically imposing guards do the actual job of protecting the wives. The wives are so closely guarded that they have become virtual prisoners in Volterra. However, Corin's ability keeps them satisfied with life.

Aro also instructs Corin to use her gift on Chelsea, another high ranking member of the Volturi, making it nearly impossible for Chelsea to leave the Volturi, because of its drug-like side effects. Marcus has repeatedly refused to allow Corin to relieve his pain over Didyme's murder. Aro is also careful not to expose himself too greatly to Corin, while Caius frequently uses Corin's gift to mitigate his boredom between punishing expeditions and battles.
