The Grey Lady

The Grey Lady is Helena Ravenclaw, daughter of Hogwarts founder Rowena Ravenclaw and the ghost of Ravenclaw House. Her quiet presence hides one of the school’s darkest family stories: Helena stole her mother’s diadem, fled, and was killed by the Bloody Baron, whose ghost still haunts Slytherin. Her final conversation with Harry reveals the hiding place of the lost diadem, one of Voldemort’s Horcruxes. LEGO’s translucent, pale treatment turns an obscure background ghost into a visually distinctive figure while also completing another piece of Hogwarts’ four-house mythology.
