Introductions are in order:
Mercy Isabella Lestrange was born on May 29, 1980 to notorious Death Eaters, Bellatrix and Rodolphus Lestrange. She grew up only knowing her parents from photographs, as they were sent to Azkaban prison in 1981 for the torture of two aurors, Frank and Alice Longbottom. However, Mercy was lucky she had other family, and wasn't made to live in an orphanage.
After her parents were imprisoned, she was sent to live with her Aunt Narcissa and Uncle Lucius, and their infant son, Draco. The Malfoys took her in without question or hesitation. Afterall, she was one of their own. Mercy and Draco practically became brother and sister. They had no other siblings around, and were less than a week apart in age. So naturally, they enjoyed a very close relationship. Before Lucius and Narcissa knew it, the year was 1991. And it was time for Mercy and Draco to attend Hogwarts...
