Prologue
It has never been unusual for Pureblood families in the wizzarding world to inbreed with each other. Most pureblood families wanted too keep their families just that pureblood. Bellatrix and Sirius Black were to cousins who knew this story a bit to well.
Bellatrix Helena Black was the middle child of Cygnus and Druella Black. She wasn't the typical Black daughter, she was not shy or demure like her younger blonde sister Narcissa nor was she Black haired and silver eyed like her older sister Andromeda. Instead Bellatrix(known as Bella to her sisters and Sirius) was tall and lean with curly brown hair and honey colored eyes. She was a tomboy and the closest Cygnus ever came to a son since his wife's several miscarriages of sons. Bellatrix grew to hate her Druella because of the attention her sisters got from her, but the ignorance she showed to Bellatrix.
Sirius Orion Black was the oldest son of Walburga and Orion Black. He appeared to be the perfect heir for the Black family. He was tall with midnight black hair that appeared to sometimes be a deep shade of midnight blue. He had Silver eyes that shone like the stars in the night sky according to a Diary entry of Bellatrix's. Sirius never wanted to be like his family he was very much against all of the pureblood mania they supported.
Sirius and Bellatrix had spent many summers together growing up. They had been playmates before friends or before they fell in love. They spent so much time together because Sirius' brother Regulus was to young to rough house with, Narcissa didn't want to be anything but a proper Black daughter, and Andromeda spent most of her time with her one time betrothel Romulus Zambini. They were a constant in one another's lives. Sirius learned French from Bellatrix when she came home from Beauxbatons over the summers. Sirius had promised Bellatrix when he was ten right before he went to Hogwarts that he would be different from all the other Blacks.
Sirius befriended the loud mouth James Potter, the wear wolf Remus Lupin, and the social outcast Peter Petigrew, Bellatrix had only two close friends, two sisters named Ceceil and Danielle Howard. Sirius and James had started out best friends but drifted apart during their teen years at Hogwarts because he thought it was funny Sirius took his betrothal to Bellatrix seriously. During this time Sirius was closer with his friend Remus who understood feeling different around James.
After Bellatrix graduated from Beuxbatons she mostly traveled since having a steady job would not have been conducive to staying on her mother's good side. Bellatrix did enjoy writing books though and was a hopeless romantic according to Sirius in a letter he wrote to his good friend Remus Lupin. Bellatrix always came home for the summer so she could spend them with her Sirius. Her beloved Sirius who inspired all of her novels and made her want to teach at her beloved Beuxbatons. Sirius wanted Bellatix to have a job even if it was strictly off limits for their family.
But this was not an easy romance for the two. The First war was brewing and Sirius felt he was being pulled every which way, his parents wanted his brother and himself to join Voldermorts ranks, his friends insisted he joined the order of the phoenix with them, and Bellatrix did not want her love to fight. Alas, Bellatrix knew that Sirius would fight, she promised herself that she wouldn't worry because she knew he would not be happy if he was not fighting for what he believed it.
This is their story, this is the story of a love so pure and true no love has matched this story since the Days of Romeo and Juliet. For this is the story of Bellatrix and her Sirius.
