As soon as the last Marauders were gone, Harry let go of the hold he had on their combined magic. It lashed out, giving voice to the anger and grief that had built when he had been forced to watch his friends suffer. The moment the first Order member came around the shelves, he was screaming. At Bellatrix. At Voldemort. At some unnamed Death Eater, who had taken his godfather and professor away. Then he pulled the magic in again and ran for the Atrium. The Department of Mysteries was the best-protected area of the Ministry. Far too few people were around to witness what they were supposed to see. The Atrium was the centre.
