In Dumbledore's tower, just before an attack on Hogwarts, the old headmaster and Professor McGonagall are talking.

"The attack is scheduled for tonight, Minerva, and I must help protect the school. You and the other head of houses will stay with the students in their dormitories!"

"But Albus! The risk! Surely you wouldn't…!"

"If I have to, to stop him Minerva, I will."

"But who will run the school? Protect us?"

"I have a friend, Carlisle Cullen. He's a vegetarian vampire. If I die, you are to be Headmistress. Take Remus and four students and get his coven to help. Carlisle will not let me down!"

Later that evening, Voldemort attacked Hogwarts School of Witchcraft and Wizardry.

Albus Dumbledore died.
