Clara was born the twin of a vampire, making her immortal. She had no special powers, was no more bulletproof than the next human, but she stopped aging in her 20's, making it clear she was not fully human.
Her twin sister, Anastasia, was raised with vampires, while Clara grew up the daughter of the Count and Countess of Bathory. Her true father, the Count, never treated her differently, even though he knew her twin was not his blood. The question of Clara's legitimacy was always there, but the older she got, the more she looked like her father.
Clara grew up kind, and gentle, the opposite of her sister, the light to her darkness.
Sometimes when Anastasia visited Clara and their mother, she brought along an eccentric blonde vampire named Lucas. Clara liked him, but he only had eyes for her sister.
Ana was very encompassing, always having whatever she wanted. When her mate was killed, she sent Lucas to take care of Clara, and the two fell in love. Ana returned from battle, a criminal amongst her kind, and went into a comatose state.
Clara left the house and returned to discover Ana had woken up, long enough to seduce Lucas and get him to sleep with her. Clara's heart was broken, knowing that Ana had tried to take the one thing that belonged to Clara, the only person she wanted for herself. Not to mention, Lucas had spent so much time reassuring her he felt nothing for Ana anymore, only to give in so easily. Clara told him she needed time.
Ana became with child from her one night with Lucas, and Clara's feelings were damaged further having to see her sister swell with the child of the man she loved. Clara had hoped to have his child, but she hadn't been able to yet.
The child was born, a girl, and their mother sent for her ex-lover, the Incubus Balthazar, to take the child to the vampires. Ana's actions had put a knife over all their heads, and none of them wanted the baby to suffer for her crimes. The baby was named Elisabeth, and she was sent away, her lineage remaining a secret.
Clara's heart remained bruised over the next few years, and she still hadn't forgiven Lucas before the three of them had to flee when Ana's bloodthirsty rages were discovered by the humans. The Countess took the blame, and sent her children away so they wouldn't be in danger. Lucas left the sisters but he and Clara kept in touch over the next four centuries.
Ana was still in a comatose state most of the time, dead inside from the grief of losing her mate. Clara dutifully took care of her sister, not complaining about any of it, and eventually forgave her for her night with Lucas.
Lucas' letters expressed regret, guilt, and love for Clara, but they could never be together with Ana's crimes hanging over them.
