There is a room in the Department of Mysteries that is kept locked at all times. It contains a force that is at once more wonderful and more terrible than death, than human intelligence, than forces of nature. It is also, perhaps, the most mysterious of the many subjects for study that reside there. It is the power held within that room that you possess in such quantities and which Voldemort has not at all.” -Albus Percival Wolfric Brian Dumbledore
—Harry Potter and the Order of the Phoenix by J. K. Rowling
