Dumbledore just nods sagely, as if he hadn’t been keeping a monumental secret. "The Prophecy that said you would be the one to defeat Voldemort, the one that caused him to go after you and your parents. The Prophecy itself is here in the Ministry, the Department of Mysteries. Voldemort is after it, but now that you’re here, we’ll remove it and take it to a safe location. It can only be taken by the recipients of the prophecy, after all."
