Dark magic flashed and sizzled through the smoky air as the battle in the Great Hall raged on. Walls were crumbling, people were fighting and chaos was rampant. The house elves charged from the kitchen, Kreacher leading the way as he avenged his Master. They bit the ankles of the Death Eaters and stabbed them in their knee caps with knives from the kitchen. Peeves zoomed over head, dropping bubotuber puss and stink bombs onto the heads of unsuspecting dark witches and wizards. Harry saw Neville take down Nagini, slicing her head off as easily as if he were slicing a tomato for a sandwich.
This was it. This was Harry's chance. He whipped out his wand and charged towards Voldemorte. Before he could utter a spell, the doors of the Great Hall busted open and Harry was blinded by a great white light. The sound of squealing tires assaulted his eardrums and the smell of burning rubber invaded his nostrils.
Mr. Weasley's Ford Anglia hauled ass across the Great Hall! People screamed and leapt out of the way as the car peeled across the marble floor, leaving a line of flaming tire marks in its wake. Harry only had a second to spare as he tucked and rolled out the car's path and WHAM!
The car creamed Voldemorte like a can of corn.
Everyone was silent as they processed what happened, then great cheers erupted across the Great Hall. It was over and Voldemote was gone. The Ford Anglia turned on his wipers to cleanse itself from the leftover remnants of Voldy's nose, flashed his lights and honked his horn. The car then sputtered his way back to the forest never to be seen again, but always remembered as the saviour of the Wizarding World.
