Penumbra

Long since Lord Voldemort had killed the Potters and won the war, only pure- and halfbloods were permitted to attend Hogwarts. After his parents being tortured into insanity, Neville nearly escaped death and was found and raised by his grandmother in Germany. Now known as Connor Stein, a halfblood graduate of the german school Drakenfels, he returns back to Britain, set on revenge.
