Sophia Pistis

For thousands of years she was reborn within the body of a vampire (known as a Psyche, or blood-producer) and forced to have a child to continue the Armash bloodline (the clan which Cecilia, Karin's maternal grandmother, came from). Once the next member of her bloodline was born she would be drained of her blood to help the other vampires reproduce. It was originally believed that the only way to break the curse, according to James, was for the carrier to loose the Armash name. However, this theory was proven false as the curse still continued through James' granddaughter, Karin. Unfortunately as the vampire she was reborn in could not drain the blood of another, they had a limited lifespan and would eventually die, either through the loss of blood or unnaturally short lifespan roughly equal to those of long lived human, becoming part of Sophia's life essence in the process and forcing her to be reborn in the body of another member of the bloodline.
