Ariana Dumbledore (c. 1885 - late summer 1899) was a half-blood witch and the youngest child and only daughter of Percival and Kendra Dumbledore. She was the younger sister of Albus and Aberforth Dumbledore. At the age of six, Ariana was attacked by Muggle boys who saw her practicing magic, and, when she couldn't show them the trick, attacked her in an attempt to stop her from using the magic. This left her traumatised to the point of rendering her magical abilities unstable and uncontrollable. This prompted her father to attack the boys and be imprisoned in Azkaban, while her mother moved the family to Godric's Hollow and kept Ariana hidden away from the general population, because she knew Ariana would be taken to St. Mungo's hospital if her condition were widely known. During a fit when she was fourteen years old, Ariana caused a magical explosion that killed her mother, after which her older brother Albus became her guardian. Ariana died when she was accidentally struck by a curse in a three-way duel between her older brothers and Dark Wizard Gellert Grindelwald, Albus's friend at the time; it was never known who struck the killing blow. This event would have a profound impact on both her brothers' lives. Show less «
