Bellatrix Black

Biography
Bellatrix was raised to value blood purity and disowned several of her family members who didn't support the same values. During her years at Hogwarts School of Witchcraft and Wizardry, Bellatrix was sorted into the Slytherin house.

After her schooling, she married the pure-blood Rodolphus Lestrange, even though she didn't really love him, this was just expected of her by her family. She also became a Death Eater after Lord Voldemort rose to power.

After Lord Voldemort's downfall, Bellatrix, along with Rodolphus, his brother Rabastan, and her distant cousin Barty Crouch, Jr., kidnapped and tortured Frank and Alice Longbottom. The four were eventually captured and imprisoned in Azkaban.

In 1996, Bellatrix escaped from Azkaban and rejoined the Death Eaters. Like her cousin Sirius Black III, Bellatrix lived in hiding to avoid imprisonment.

In the Battle of the Department of Mysteries, Bellatrix fought with her niece, Nymphadora Tonks, and then later fought her cousin Sirius. Bellatrix then killed Sirius and he fell into the Void.

During the Skirmish at Malfoy Manor, Bellatrix tortured Kreacher and Hermione Granger and managed to kill Dobby.

In the Battle of Hogwarts in 1998, Bellatrix murdered her niece, Nymphadora. After the retreat, Bellatrix duelled Hermione, Ginny Weasley and Luna Lovegood all at the same time. When a Killing Curse nearly hit Ginny, Molly Weasley intervened and killed Bellatrix
