Blood Promises
Chapter 1 - Prologue
14th March 1979 - Yaxley Manor
Helena Yaxley was doomed. She knew her life would be forfeit once her brother Corban figured out she was pregnant. She'd spent many nights in bed with a lover before he'd gone to war with the Order.
Helena knew that she'd be a pariah once word got out that she was pregnant with a bastard child, especially when the father of the child was a blood-traitor. Although she was only two-months pregnant, she knew it was only a matter of time before she started showing.
She would be leaving come morning. Discreetly, trying not to raise suspicion, she had been withdrawing out some of the contents of her vault and planting the ideas into her friends' minds that she wanted to explore Europe and travel for a year.
Her brother, having heard from her friends that she'd wanted to travel before she'd be forced to marry had allowed her to leave under a few conditions. As the last living Yaxley male, he oversaw arranging her marriage. When she returned after the year, she'd have to marry Rabastan Lestrange. The last condition was that she'd sign a blood contract.
She would be signing away her firstborn girl to marry the Malfoy's firstborn son. Arranging marriage contracts before the children were born weren't unheard of. It was customary practice amongst the society circles. However, using blood and dark magic wasn't common. Only the ancient and noble families such as the Blacks' and Malfoys' still used them.
She'd only hoped that her child was born a boy or that the Malfoys' never had a boy. That would be the only way the contract could be voided null.
18th September 1979 – Muggle London
Everyone had thought that Helena was overseas when in fact, she had hidden in the muggle part of London. Helena reconnected with an old friend, Andromeda Tonks, who had managed to acquire her some fake muggle papers. The disowned witch knew what Helena meant about forbidden love and so they had bonded quite easily. She was the shoulder Helena cried on when she had heard that he had been killed.
It was late at night and she was about to leave after visiting Andy and Ted when she felt it. Her water had just broke. Her shocked gasp alerted Andromeda who knew exactly what had happened.
"The papers and bag" Helena gasped. They were at her flat.
"I'll be right back, just stay right here" Andromeda immediately apparated to Helena's flat and was back within minutes. They rushed her to the nearest muggle hospital.
They had rehearsed this situation many times. The receptionist at the hospital asked for her name and for Andromeda's relation to the her. "Helena Yates" she said. "Andy's my cousin." It wasn't a lie; the Blacks' were very distantly related to the Yaxleys'.
She was immediately rushed into a birthing suite when she felt something seep onto her leg. She was bleeding.
Andromeda held Helena's hand as she watched the nightmare unfold. Muggle doctors aren't nearly as advanced as Wizarding healers. Muggle births are known to be more labour-intrusive. She knew that her friend would die trying to birth the child but willed herself to stay strong.
Helena had told Andromeda of her plans when she was in her second trimester. Helena would anchor a glamour charm into the child's magical core to hide the identity and looks of the child until told of their true heritage or on the child's 20th birthday. Although Helena loved her unborn child, she could not bring it to the magical world and face her brother, and if she did not return before the year was up he would hunt her down. Thus, she'd decided to hide the baby where no one would look; in the home of a muggle couple. She would place the child into adoption.
At 3:49am on the 19th of September 1979, the baby was born and Helena Jacqueline Yaxley had passed away from blood loss. With tears streaming down Andromeda's face, she vowed to fulfil Helena's plans. When they were alone, Andromeda channelled the child's magical core and changed what the baby would look like. The blonde tuft of hair on her head would change into thick, brown locks and the baby's eyes would become brown.
Andromeda placed the child into adoption, the only requirements she had was that the child's first name begin with a 'H' and her middle name begin with a 'J'.
Diane and Peter Granger, the muggle couple that adopted her, named her 'Hermione Jean Granger'.
