Hello to all! Now I know that others have answered the question of 'What would happen if Bellatrix and Voldemort had a kid?' I'm just adding my story to the collection. Hope you enjoy it!
Disclaimer: I sadly do not own Harry Potter. That honor goes to J.K. Rowling, so if you recognize anything from the books, it belongs to her.
Now, on with the story!
The guards were apprehensive of the woman, even though she was wandless and, by the looks of it, about to go into labour any minute now. Still, this was no ordinary old witch. No, far from it. This was the woman that single handedly tortured and killed countless muggles and wizards alike. This was the person who was most feared in the wizarding world, second only to you-know-who himself. She painted a pretty terrifying picture with her tangled mess of black curls, sunken cheeks, permanent scowl, heavy lidded black eyes, striped prison uniform in tatters, and a stomach stretched to its limit. When carrying children, women usually have a certain glow about them, and this one was no exception. Only, unlike the normal happy and healthy glow, Bellatrix Lestrange was surrounded in a dark aura. It was no wonder that the human guards were afraid of her, of what she had already done and could do, even though a wall of enchanted bars separated tham and dementors were posted every few feet.
Inside the dank, stone cell in Azkaban, Bellatrix's eyes widened at her first contraction, the pain hitting her like a hard blow to the abdomen. A slight flinch was all she would allow herself, not wanting to appear weak in front of her captors, no matter how much it hurt. At first they came sporadically, but now it was more frequent and it was getting harder for her to do nothing more than flinch.
Carefully, an older woman with graying hair came into the cell and knelt next to Bellatrix. She was the only doctor stationed at Azkaban, meant to help prisoners only in emergencies. Oh, it would be so easy! So dreadfully easy for Bella to snap her neck, but she used every ounce of her self control not to hurt the witch, knowing that if she wanted to have this baby, then she would need the help of this woman. And since it was a child that bore her master's flesh and blood, there was nothing she wanted more.
As it turned out, the witch proved well worth the fee of not killing her because in a few hours, after extreme pain and a couple of escaped screams, Bellatrix Lestrange held her baby girl. The doctor was frozen in shock, having previously believed it impossible for Bellatrix to look at anything with genuine warmth in her eyes. However, the way that she looked at her daughter was nothing if not warm.
The child's pale skin was tenderly held in her mother's equally pale arms, where she periodically stroked the baby's soft, black tuft of hair. When the child had been calmed and her eyes opened, Bellatrix gasped. Those bright green eyes, the same color as a climbing vine, were the mirror image of her lord's. She beamed.
The witch, having regained her composure, walked the few steps to the new mother and held out her hands expectantly. "The child, if you please."
Though it caused her physical pain to give up the daughter of her master, she reluctantly handed her to the woman saying, "Take her to my sister, Narcissa Malfoy." And then, as an afterthought, "Her name is Ivy."
The witch took the newborn in her arms, closing the cell door after her. Once at a certain point away from the prison building, she dissapperated, holding tightly to the now wailing infant. When she reappeared, with all of her limbs and the baby's intact, she was indeed in front of the Malfoy Manor.
