I am Aurora Sinistra, former Healer at St. Mungo's Hospital of Magical Maladies and Injuries, former member of the Order of the Phoenix, and former professor of astronomy at Hogwarts School of Witchcraft and Wizardry.
I was born to Vesper and Persephone Sinistra on the morning of 23rd of March 1960 in Sinistra Manor. I was the youngest of their two children, the oldest, Aelius Sinistra, was six years my senior. My father, Vesper, was the only son of Cepheus Sinistra, and so the heir of the Sinistra estate. As I remember him, he was quite tall, with a square jaw, dark green eyes, and black hair, although most of it was grey by the time he was forty. He was always very well dressed and no matter what the occasion, he wore a serious expression. He was a brilliant alchemist.
My mother Persephone was from the Selwyn family. She had a sister, Circe, who married Abraxas Malfoy. My mother was small, slender, with a thin face, blond hair, and blue eyes. She was ill all the time that I knew her, and always nervous or depressed. She died when I was seven.
Aelius and I both inherited our mother's looks, except Aelius had the fortune of growing to be quite tall, and we both had the black hair of Vesper Sinistra. Aelius grew to be a handsome wizard. He was always well groomed with short and well kempt hair. As our father, he always dressed well, though he only ever wore black. As for myself, I am about 5'4", my hair has usually been kept long with bangs that, as my Aunt Circe said, "frame my face," and the only accessory I ever wear is a pair of rectangular-framed eyeglasses.
My father invested little of his time in his children, although he was never cruel and rarely unkind, he did of an air of cold indifference around us. He did, however, made sure his children learned to display the "proper dignity and pride befitting of a Sinistra." He did seem pleased that both of his children made it to Slytherin. And though he never said anything, I am sure Aelius and I would have known if he were not proud of us.
