A Department in the Ministry of Magic whose actions were shrouded in secrecy, as those who worked there sought to unravel the mysteries of the world – including research into time, death and love. The people who worked there were called Unspeakables: witches and wizards who undertook this research and were not allowed to reveal any details about their jobs. It was in this department that all prophecies were housed, including the prophecy relating to Harry, Voldemort and the fate of the wizarding world.
