Sarafine Duchannes

Sarafine is a Caster - an immortal, witchlike being whose nature is either Light or Dark. She is the mother of Lena Duchannes, and widely known as the most powerful Dark Caster to have ever lived in her own world. Driven by her hatred of Mortals and her desire for power, her current goals are to either recruit or kill her daughter, elimate the rest of the rest of Team TARDIS 2.0 if necessary, and then combine her efforts with the powerful Incubus (and the man she considers her mentor) Abraham Ravenwood in order to exterminate the human race and allow supernatural beings to claim the world for themselves.

Canon History
Since Casters in her family do not learn their 'real' names up until the self-discovery of their Claiming at age sixteen, Sarafine was known as Izabel Duchannes growing up. Izabel was notably different than Sarafine in personality - though intelligent and generally kind-hearted, she also lacked a great deal of self-confidence, and constantly agonized over what her family's Curse might mean for her. Members of the Duchannes family were Claimed by either Light or Dark when they turned sixteen - due to a centuries-old curse, they had no choice in the matter, and Izabel was terrified at the possibility of going Dark. She spent a great deal of her early life 'proving' herself to be a good person - through good deeds, charity work, supporting her family and friends, and general acts of kindness - in hope that she could ensure she'd be Claimed as Light. In her early teenage years she met John Eades, a Light Caster who she eventually fell in love with. Izabel believed with a significantly greater amount of certainty that her love for John would anchor her to the Light.

However, this was not the case, and on her sixteenth birthday Izabel was Claimed for the Dark and disowned by her entire family as a result. She also learned her real name, Sarafine, though as a measure of rejecting her Dark Nature and all things associated with it she continued to go by Izabel for some time afterwards.

Sarafine initially believed that she could fight her nature, and cling to the person she was despite the results of her Claiming. For some time, John's love and loyalty helped her to do this (she married him several years after her Claiming). When she was nineteen, she became pregnant with her daughter, Lena, and was further motivate to fight to keep herself from becoming a monster.

Eventually, however, she fell prey to the manipulation of Abraham Ravenwood - an ancient, powerful Incubus demon who'd predicted the power Sarafine would have. Sarafine was a Cataclyst - a Natural (essentially, the most rare and powerful sort of Caster) who'd gone Dark - and as a result, the slow process of losing herself to darkness was even more violent than it was for most Casters. As time passed, even as she tried to cling to the ones she loved, she became consumed by a bizarre obsession with fire and the irrepressible desire to burn things. Abraham encouraged this urges, and also motivated her to expand her power by telling her that there was a way - if she could find it - to save Lena from the Curse that had haunted their family for years. But under Abraham's influence, Sarafine's symptoms only worsened. And while her power grew, she continued to slowly lose herself.

When enough time had passed, Abraham began to poison her thoughts and turn her against John, insisting that he would eventually betray her upon realizing what a monster she was. Sarafine refused to believe this, however, and in an effort to prove Abraham wrong she approached John and finally told him the truth. That she'd been secretly meeting and training with Abraham for some time, that she'd been indulging her Dark abilites - only for the sole sake of becoming powerful enough to save Lena, of course. But John was horrified, and, as they argued, realized how Dark Sarafine had become. He then told her that he was leaving her, and taking Lena with him, for their own safety - he no longer trusted his wife around their daughter. The threat of losing both her husband and her daughter pushed Sarafine to her breaking point, however. In her fury and despair, she started a fire that killed John and endangered Lena - and then fled.
