"The Ministry of Magic does not wish me to tell you this. It is possible that some of your parents will be horrified that I have done so – either because they will not believe that Lord Voldemort has returned, or because they think I should not tell you so, young as you are. It is my belief, however, that the truth is generally preferable to lies, and that any attempt to pretend that Cedric died as the result of an accident, or some sort of blunder of his own, is an insult to his memory.
Every guest in this Hall will be welcomed back here at any time, should they wish to come. I say to you all, once again - in the light of Lord Voldemort's return, we are only as strong as we are united, as weak as we are divided. Lord Voldemort's gift for spreading discord and enmity is very great. We can fight it only by showing an equally strong bond of friendship and trust. Differences of habit and language are nothing at all if our aims are identical and our hearts are open.
It is my belief - and never have I so hoped that I am mistaken - that we are all facing dark and difficult times. Some of you in this Hall have already suffered directly at the hands of Lord Voldemort. Many of your families have been torn asunder. A week ago, a student was taken from our midst.
Remember Cedric. Remember, if the time should come when you have to make a choice between what is right and what is easy, remember what happened to a boy who was good, and kind, and brave, because he strayed across the path of Lord Voldemort. Remember Cedric Diggory!”

- Albus Dumbledore (1995)
