Ghost of a Lady

Backstory

My name is Helena. I was born in the late 10th century. I am the child of Rowena Ravenclaw who was too busy with her school to pay me any attention! So after i graduated I stole her diadem become more clever and important and ran away to Albania, but when my mother became fatally ill she asked the baron to take me home. When I refused he took my life. I now roam the corridors of Hogwarts as the house ghost of Ravenclaw.
