You were one of the most powerful witches/wizards of your age. You currently were at the astronomy tower, gazing down from the window until you heard footsteps behind you. You turned to who it was, it was Draco.

as you turned around to him he immediately pulled out his wand and pointed it to you. You tried to calm him down but he wouldn't calm down. "Don't you understand?! I have to kill you! Or he's going to kill me.." he said in a strained voice before pulling up his sleeve, revealing the Dark Mark.
