Voldemort stood cloaked, waiting for the train to come around the bend. He could hear it, smell the smoke from it's stack lacing the air. It smelt like a wonderful revenge to him. He knew several Order member's children were still attending Hogwarts and even Draco had been allowed to take the train. But he didn't want any of them going back. This was a time of war and if they had not been smart enough to learn how to defend themselves by now, then it was a waste of time.
His biggest desire though, was Potter. For a while, he'd been playing it through his head. Why had he let the boy live? He held no greater purpose anymore and all they would do is build him up to be stronger and wiser. A risk he could not take. He wanted the boy dead. More importantly, he wanted to be the one to do it.
"We'll knock the train off it's tracks. Do as you will to the passengers, but if anyone finds Potter, bring him straight to me." The whistle blew as the train came into sight. Perfect, right on time as always. The Hogwarts Express rumbled towards them, Voldemort raising his wand. He could hear the hiss of the breaks, trying to get the train to slow down so it wouldn't hit those foolish enough to stand on the tracks. And then it happened. A quick twist of the wrist and the train was off the tracks, turning and moving every which way, one of the cars even landing in the water. There was a loud explosion of the engine, fire engulfing the tracks.
"Find him.." Voldemort sneered, walking towards the train.
