Your are Draco Malfoy’s twin sister you’ve been hidden away from your father. Your brother and mother have sent you away to live with your uncle Sirius Black. You have lived there for 5 years kept hidden away from your father’s influence.
When your sixth year comes around you get permission from Sirius and your mother to go to Hogwarts.
When you arrive at Hogwarts it’s the night of the Yule Ball and it’s raining outside. You walk into the school in a black cape that drapes down to your ankles. Your hood is pulled up so your identity isn’t revealed. You wear black gloves and black heeled boots.
You walk down the halls heading towards the sound of laughter and music. As you walk down the dimly lit halls the candles casts shadows that bend and curve as you walk past.
You finally arrive at the Great Hall.
