Marius la Rue was a pure-blooded wizard who believed completely and truly in blood supremacy. He belonged to an ancient dynasty of French wizards and was lined up with around five suitors to marry - his prospect wife and spares, if he should so need them. He never thought that he'd ever be able to abhor the philosophy he was brought up on, until he met a muggle woman in Paris. Aurelia Beau was no stranger to the wizarding world; her brother was a muggle-born wizard and she grew up envying him. She knew as much as the next wizard would so when she met Marius with his blood supremacy and muggle-hating ways, she was calm and collected. Besides his obsession with blood purity, he was a decent man and Aurelia found herself falling for him. She was patient and, eventually, he looked past it and saw the whole philosophy that he was brought up on was isolating and, quite frankly, wrong.
The couple, once married, went on to have triplets; Flora, Skylar, and Sébastien. The family lived in a wealthy district in Paris and life was comfortable. They spoke mainly in English, Aurelia's mother tongue and learnt conversational French on the side. They attended an international school in Paris until they could attend wizarding school, providing they inherited their father's gene. All of the children, unfortunately, were late bloomers when it came to having their magical experience and worried their father. Whilst he was long since ashamed of leaving his life behind, he didn't want to be the only one of his siblings to produce squibs so naturally he waited anxiously for them to have their first magical experience whilst his wife was perfectly calm and didn't care either way.
Skylar's magical experience was making the family dog, Dedou, turn from the snow white colour to a vivid pink. This was definitely more exciting in comparison to her siblings' - who also had theirs - but that was irrespective. Happy that all his children had inherited his gene, Marius celebrated.
The children went to different wizarding schools as per their own desires; Flora went to Beauxbatons, Skylar to Hogwarts and Sébastien to Durmstrang. At Hogwarts, Skylar was sorted into Ravenclaw and became a prefect in her final years. She had passed all of her exams with good grades and was set out to take the world by storm. Unfortunately, her brother had become sympathetic to the dark side of wizardry and joined a cult-like group and eventually murdered Flora. Hearing rumours that he was targeting his parents and remaining sister, her parents went into exile whilst Skylar stood strong, confident she could take him on.
