House Ghosts

Roam the Hogwarts corridors and it won't be long before you feel the icy chill of a ghost passing through - Hogwarts has many of them. In the wizarding world, ghosts are usually left behind by wizards and witches who have unfinished business - and Hogwarts has four ghosts that represent each house. Slytherin's ghost, The Bloody Baron, is the scariest ghost and comes with chains and silvery blood stains; Nearly Headless Nick, the Gryffindor ghost, is far jollier, even if he is nearly headless; The Grey Lady is the mysterious representative of Ravenclaw House, while Hufflepuff have the merry Fat Friar.
