The Battle for the Prophecy


 * Lucius and Voldemort both commanded the battle, but at different times. When Lucius failed to retrieve Harry's Prophecy, Voldemort stepped in and dueled Albus. After failing in the duel, Voldemort tried to possess Harry in an attempt for Dumbledore to kill his favorite pupil. The same goes for Harry and Dumbledore as Commanders.

Right before the battle, Voldemort implanted an image of Sirius being torchered in the Hall of Prophecies, knowing Harry would come and save him.
