The Aurors

Bellatrix and Rodolphus left behind four children when sent to Azkaban, and these four children tried their hardest to be kept together with unfortunately no success. For years, they would ask their guardians "when's mom and dad coming home?" to be met with the heartbreaking word, "never,"
Eventually, their parents escape Azkaban and the children hear of this. Deciding to rebel, they run away and go back home. But something isn't quite right this time.
