Sirius Black is a player. Simple and plain.
Of course, everyone knew that. But sometimes, Sirius went too far. Like in his sixth year, with girlfriend Sierra Kingsly.
Flashback
"Sierra, what were you thinking? Sirius Black, of all the people! You're in Ravenclaw for crying out loud, this should be easy knowledge for you!"
Sierra nodded silently, agreeing with her best friend, Rebecca. The silence had been killing her since she told Rebecca the news, that she was now carrying Sirius Black's baby. It was the result of one stupid night after a visit to Hogsmeade, and Sirius happened upon a bottle of alcohol. Needless to say, one thing led to another, and now Sierra was in a compromised position.
Rebecca, though, took no time in lecturing her best friend, and fellow house-mate. "Sierra, everyone knows he's a player. Everyone! Him and that group of popular Gryffindor kids, James, Peter, Lily, they all will support Sirius! Everyone will blame you!"
Sierra sniffled, wiping away another tear. Luckily, the bathroom was deserted, with no one to hear the private conversation. "At least he's a pureblood," Sierra said dryly. "Mum and Dad will be so proud. They always said that our pureblood family line had to be carried on with another pureblood family."
"Yes," Rebecca scoffed. "I'm sure when they said that, they meant Sirius Black, of all the people."
Sierra went on to drop out of Hogwarts to hide her pregnancy. She took private schooling lessons, and being a Ravenclaw, finished school early. But when her Mother and Father found out, Sierra was thrust into the streets, considered disowned by her own parents. It didn't take long for Sierra to be recruited into the Dark Lord's group of Death Eaters, after the hunger and fear set in of living on the streets. She found a family in a place where most experienced pain or fear. Soon she delivered a baby boy, Leo. The Dark Lord knew of Leo's heritage, and used it to his advantage, teaching Leo hate and destruction with the use of Dark Magic.
Sierra watched proudly as her son was taught by Voldemort.
Sirius had had no idea of Sierra's position, or even of Leo being alive. He considered it another one of his one night stands, and broke it off with Sierra the night after. His seventh year though, he was swept off his feet and tamed by a girl named Leah Cairo. They, as did Lily and James, got married after school, and followed careers, Sirius as an Auror and Leah as a writer.
They got married and had four children. The first was a girl, Chelsea. She looked like her father, with long black hair and brown eyes. After a year they had Sophia, who had dirty blond hair cut short, and after another year came Morgan, a beautiful baby girl with gorgeous blond hair and icy blue eyes, like her father. Three years later came Max, the last child, a boy with black hair and brown eyes.
Chelsea was five, Sophia four, Morgan three, and Max only months old when the night with the Potters happened. Voldemort and a eight year-old Leo made their way into the Potter home. They would have been victorious in killing the Potters, had Sirius not shown up. Leo, being distracted by the sight of his father, only crippled the Potters before he and Voldemort ran away.
Voldemort's fate stayed the same. Leo went into hiding with the Malfoys, one of the top secret Death Eater families willing to raise the apprentice of the Dark Lord. Sierra happily accompanied her son.
Unfortunately, the Potters were in a state that couldn't be changed at the time. They were paralyzed, minds shut down, only a pulse showing that the couple were still alive. Baby Harry was forced to live with his aunt and uncle, unable to visit his parents until he was old enough, a legal adult.
The only thing that changed about Sirius' fate was that he knew of the children he was leaving behind while going to Azkaban. He knew of his ex-girlfriend turned Death Eater, and their evil son. He knew of his wife, who couldn't afford a stable home without him.
Leah couldn't raise her kids alone. Four children to an unpublished writer was a burden she couldn't afford. The Ministry, seeing Leah's troubles, took away Leah's youngest daughter, Morgan. She was transported to Child Services, and swept far away from her mother. Leah grew to hate Sirius for leaving her with a burden that cost her her youngest daughter.
Leah lived in Australia until the time came for Chelsea to start school, which is when they moved back to London. During Chelsea's fifth year, Sirius Black escaped Azkaban, and Leah told her children the truth about their family.
The recently formed Order contacted Leah afterwards. She wanted nothing to do with the group, but didn't deny her daughters and son the opportunity to meet their father.
Morgan, though, lived a very different life, which is where this story starts.
