Helena Ravenclaw (The Grey Lady)

Helena Ravenclaw, also known as the grey lady , is the House Ghost of Ravenclaw. Helena was the daughter of Rowena Ravenclaw, the finder of Ravenclaw.

Helena was jealous of her mothers cleverness and importance that she (during her school years on Hogwarts) stole her diadem so she would be more clever then her mother, Rowena. She ran away from Schotland and ran to Albania. Helena believed that the diadem could help her become more important then her mother. Rowena Ravenclaw, ashamed of what her daughter did, pretended that she still had the diadem.

When Rowena lied fatally ill on her deathbed, she asked the Bloody baron ( who was deeply in love with Helena) to find Helena and bring her to her so she could see her one more time. When he came to Albania, Helena didnt want to go with him and ran away from him. She hid the diadem in a hollow tree. The baron was so angry that she wouldnt come he stabbed her with a knife out of anger.

The diadem was later found by Tom Riddle and he made a horcrux of it. The horcrux was destroyed by the friendlyfyre created by Vincent Crabbe.

In the first 2 movies Helena Ravenclaw is portrayed by Nina Young. In The Deathly Hallows part 2 she is portayed by Kelly MacDonald.
