"Bellatrix… My most faithful, powerful, beautiful servant…" Voldemort all but purred in Bella's ear circling her like some kind of marine predator. "Do you trust me?" The monster asked.
Bella's eyes shone with devotion and - despite her best efforts - some long buried mockery of love. "With my life and my heart, I am yours, Master." She whispered kneeling and kissing his robes as he came to a stop in front of her. Bella felt a tingle of desire shoot down her spine when Voldemort laid his hand on her head, almost affectionately.
"I am pleased to hear it, my Bellatrix, so very pleased. But I have a something to ask of you."
"Anything, Master. Anything!" Bella took Voldemort's hand in her own and placed it on her cheek brushing her lips against his long, cold, white fingers.
Voldemort smirked. "Would you like to become more powerful? More beautiful? To better serve your Master?"
Bella gasped, her eyes shining with tears she bowed again, pressing her lips to the monsters robes. "Yes! Yes! Anything to please you, my Lord!" She said breathlessly, almost moaning in ecstasy.
"We will begin immediately." Voldemort snapped stepping around her and striding from the throne room. "Follow me, Bellatrix."
What followed was worse than physical, or psychological torture. Voldemort literally cut Bella apart, dissecting her piece by piece. Bella pleaded with him to stop after two days, but no matter how much she begged, or cried, or screamed he never stopped.
Bella didn't know how long it had been since he started, but one day, or it could have been night, she didn't really know, the pain suddenly stopped. Bella awoke to a pure white room, with no windows, no doors and no furniture. She was naked, alone, and unable to sleep she waited for her Master to return. It could have been hours or days later, when one of the white walls shifted and Voldemort walked into Bella's prison.
"You're awake? How extraordinary. How do you feel my dear?" He asked; his crimson eyes seemed to glow with power.
"Wha'… What…" Bella tried to speak but all that came out of her mouth was a gasp and a hiss. Her tongue felt sluggish in her mouth and her jaw ached. She twirled her numb tongue around her mouth; it felt foreign, it did not feel like her mouth anymore. Her teeth had changed, they were sharp, jagged even and when her jaw was closed they seemed to interlock tightly.
She raised her hands to her face and froze, her skin was an off-grey almost blue colour. Dark black markings circled her wrists and wrapped down her arms, she traced one with a black claw-like nail. It travelled down her slim arm to her shoulder and split one disappearing down her back and the other down her chest.
Again it split connecting with an identical marking on her left side at her collar bone then down the centre of her chest to her belly-button. Blinking owlishly, she looked back at her Master.
"What did you do to me?" She managed to growl, her sharp teeth nipped and cut her tongue as she spoke.
Voldemort laughed, "Nothing you didn't agree to, my poor, poor, Bellatrix."
Bella's eyes narrowed and she struggled to stand, her legs shook violently and she collapsed. Her knees slammed into the cold white marble floor, the impact causing her whole weakened body to jar and she bit her tongue again. She hissed in pain and spat out the blood that filled her mouth, it was not red.
"What. Did. You. Do?"
Voldemort's laughter cut off sharply and he stepped towards her quickly, his hand pulled back and with an almighty crack he slapped her across the face. Bella's head snapped sideways. "You are still my servant, Bellatrix! Even if you are a filthy half-breed! You will continue to speak to me with the respect I deserve. Or I will hurt you… Again."
Bella froze; "H-Half-breed!" No-no-no… She sobbed it couldn't be true. Her body shook violently with every gasp.
"Yesss." Voldemort hissed. "A half-breed… Part witch, part vampire and part werewolf." He laughed again. "It almost seems fitting really, that it was only you out of the dozens of witches and wizards that went through the same procedure survived. You, who had so much pride in your bloodline, so much for the ancient and noble house of Black!"
Bella rocked back and forth clawing at her arms and chest, her new sharp nails cut deeply into her blue skin and drew blood. Bella looked down at her claws, they began to shake more violently. The blood that splattered around her still wasn't red, not anymore. Now it was black.
After what Voldemort did to her, she fled the castle. He had turned her into the one thing she hated the most, a half-breed. The pain and sorrow almost overwhelmed her as she hid away in caves. Unable to bring herself into the light and see her deformed and twisted body.
However, over months of self-imposed isolation her body healed and grew stronger. And new feelings slowly arose within her. She was the first and last of her type, she wasn't a human or a witch or a vampire or even a werewolf. Thoughts of the house of Black's pride where meaningless now.
She had found a new pride now.
She was more powerful than ever and spent every, waking, moment, learning about her new abilities. She had no desire to re-join Voldemort or even to seek out human companionship. No, the only time she needed to expose herself was when she needed to feed. The hunger drove her, urged her from town to town. It seemed like nothing would slake her primal hunger for human blood and flesh.
That's how Weasley had found her, he followed the rumours of a monster, a demon; that entered your house at night and gorged itself on all who lived inside.
