This story is based off of Beanacre0's version, with her permission I reworked it and tried to make it come alive.
Prologue
1998
On the night of Buffy's seventeenth birthday, a miracle occurred. An age old prophesy was fulfilled. A child was conceived. The day after she ran, Buffy discovered the baby. Due to her accelerated healing rate and the fact that child was half vampire, Buffy's pregnancy only lasted a three months. She gave birth to a baby girl. She named her Hermione Angel Summers.
She had registered Hermione with her own name and said her father was called Liam Angelus, remembering that Angel once told her of his birth name when they were having a quiet evening.
What she didn't know was that on the night that Hermione was born, in Italy a dying priestess from an age old cult bent on protecting the child of the Prophesy repeated the prophesy. It had been lost through the ages and now was finally found.
It told of a child born of a slayer and a vampire, that when she and her mother joined forces that they would be almost unbeatable. It also told of the child's powers and gifts. A scholar was so busy writing down the Prophesy that he didn't notice a demon hiding in the shadows.
Buffy was busy getting ready for work as Anne in a local diner. Hermione was burbling happily in her fold away crib, her chocolate eyes like Angel's sparkling in delight. Buffy chuckled and kissed her baby's head as she passed the cot.
Buffy only turned away for a moment, but when she turned back a dark blue demon with sharp horns and the infinity symbol tattooed on his forehead was standing over Hermione's crib. Hermione let out a soft wail and Buffy tried to reach the demon. Before she could reach them, the Demon grabbed Hermione and disappeared from the room.
Buffy sighed as she travelled home to Sunnydale. She couldn't find Hermione and had been searching for a month already. She soon arrived and headed right home. She greeted Joyce and then sat down with her on the sofa.
"Mom, when I was away, something big happened." Buffy began. Joyce smiled. "How so, Honey?" She asked. "I, uh, had a baby girl. She was Angel's, by some miracle. Vampires usually can't have children, but somehow we did." Buffy began. "I'm shocked. I'm a grandmother. Where is she? And what's she called?" Joyce asked. "Her name is Hermione. Hermione Angel Summers." Buffy said sadly.
"But where is she?" Joyce asked. "A demon took her, a month ago. I can't find her. I miss her so much." Buffy told her, choking up. Joyce wrapped her arms around her. "It's okay, Buffy. We'll find her. No matter how long it takes." She soothed.
The next day, Buffy was reunited with her friends. They were at Giles' house, when she decided to tell them about Hermione.
"Guys, when I was away I gave birth to a baby." She began. Everyone stared at her. "She was Angel's. It's not normal I know, but I have been with no other guy. Plus my pregnancy only lasted three months. Look, this is her." Buffy explained, pulling out a picture of Hermione and handing it round.
Willow awed at the picture. "She's so cute. Is your Mom looking after her?" She asked. Buffy shook her head. "She was taken. This demon came and before I could do anything, he vanished with her. My baby." Buffy told them, her voice sad and quiet. "We'll help you find her. Willow can put a notice out on the internet with the picture. Say she was kidnapped by a masked man. What was her name?" Giles suggested.
Buffy stoked the picture fondly. "Her name was Hermione Angel Summers. I gave her this locket with a picture of me in it. Maybe that will help find her." Buffy said with a sigh.
Angel soon returned and, when he was told, he vowed to find his daughter.
Somewhere in London 1983
A baby's wail filled the air. "What the?" Jane Granger muttered, getting out of bed pulling on her dressing gown. "John? John, get up." She hissed. John groaned and woke up, getting up and following his wife downstairs.
They opened the front door and stared at the bundle on their doorstep. Jane gently took the child in her arms and soothed her. "What's she called?" John asked. "This locket says her name is Hermione. This must be her mother." Jane replied, showing her husband the locket that was hung round the baby's neck.
A picture of a woman was inside. A young blonde girl, smiling at the camera. She was very beautiful. "John, can we adopt her? Please?" Jane pleaded. "In the morning we shall go to the social services. We'll tell them she was abandoned and we wish to adopt her." John replied, following his wife inside.
So from that day on, the baby girl was known as Hermione Jean Granger. The Muggleborn and brightest witch of her generation.
