Brilliant Prophecy Orb
Brilliant Hall of Prophecy
Battle of the Department of Mysteries
Hall of Prophecy, Department of Mysteries
Prophecy Orbs contain an audible transcript of predictions made by a Seer - a person who has the ability to parse visions of the future. The orbs are accessible only to those whom the Prophecy itself concerns. Harry Potter was lured to the Hall of Prophecy to retrieve one aimed at him by a group of Death Eaters using visions of Sirius Black as bait. The resulting Battle of the Department of Mysteries between Dumbledore's Army members and Death Eaters caused many Prophecy Orbs to be destroyed, their contents lost forever.
