Born during the early 1500's, Corin was raised by her family. She was very spoiled in nature, and wanted to go out exploring. Her father would always punish her, and send her to a place where she would learn to become a servant. Corin hated her life until everything turned around for her. This was when she met the Volturi and she was turned into a vampire.
Years after becoming a vampire, Corin was placed into the guard after Aro found her gift her gift more useful in consoling the Volturi wives. Aro hoped that Corin could help Marcus recover to some degree from the loss of his wife, Didyme. Corin then spent most of her time associating with the wives, and is also the reason to why they never leave their tower. Her main responsibility was to protect Athenodora and Sulpicia. However, she doesn't guard them so much as ease them into complacency while other, 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, the highest ranking member of the Volturi, making it nearly impossible for Chelsea to leave the Volturi, because of the drug-like side effects that inflict on her if she isn't constantly exposed to Corin's power.
In Breaking Dawn, Corin witnessed Irina walking across the hall with Ettore and Santiago. She was surprised to learn of Irina's report about an immortal child, an illegal creation, being created in the Cullen family. She, along with the entire Volturi coven departs to destroy the child, only to later find out that she is actually a half-human half-vampire hybrid.
Powers and Abilities: Addictive Contentment
- Main Article: Addictive Contentment
Corin is gifted with the supernatural talent of inducing in others feelings of contentment for his or her situation. Her talent can be comparable to that of Didyme's "Happiness Induction"; although rather than bringing out the positive feelings of happiness and joy, Corin instead brings out feelings of contentment and ease in a person, despite his or her situation. There is a drug-like side-effect to her gift to those who experience it often, as they may begin to feel unwell and uneasy without it.
Although it is not explained whether this gift is mental or physical, by the way it works it may be assumed to be a more physical gift, working similarly to Jasper Hale's empathy.
