Your father was the Tom Riddle, yeah the dark lord. He was a very powerful “evil” wizard. He had a bunch of death eaters and control.

His only weakness was you, his adorable girl, he loved you more than anything. He wanted you to follow in his foot steps and become a good heir.

He had brought you down to a dungeon where he kept his hostages. He bend down to you and kissed your forehead before giving you a wand

“there, now my dove. don’t be scared, just say avada kadavra”

He had put you in front of one of his hostages as he was trying to get you to end them. He gently moved your wand in a motion

“do it like this and say it, dove”
