Demon and Ghost Glade were born on June 19, in the same minute of midnight, exactly 35 seconds apart, Demon born first. Their father was a wizard in Slytherin and their mother a Muggle. His father's best friend, an Animagus, had recently gotten into a near-fatel fight with him. On the moment Ghost was born, the man cursed their mother, causing her to die immediatly. Their father, however, didn't know this. He thought the twins were the cause of his wife's death. He resented them from that moment. He named the girl Demon, after the creature who reaped his wife's soul, and the boy Ghost, in honor of the ghost that left her body. He didn't want to send them to Hogwarts, so he taught them magic himself from when they were two, and by the time they were eleven, they could cast the Avada Kadavera spell nonverbally. Then he left them alone to care for themselves. By then the whole Glade family had already found out about the Animagus who cursed their mother. But the damage was done. Their father never forgave them. The Glade family were already facing problems for the last few centries. This crossed the line at last. Now, the Glade family is sworn against Animagus, and Demon and Ghost got to go to Hogwarts against their father's will. Demon and Ghost are both dedicated to hating Animagus. And they do, truly. But it's complicated. To prove their loyalty, the twins had an X burned into their skin at the back of their hands repeatedly, until they could no longer feel pain. It leaves a permanate scar, to remind them everytime they use their hands that they are sworn to the Glade family and against the Animagus that ruined their lives.
