Hermione nodded, and he gestured for her to continue. "Tom Marvolo Riddle, descended from the Gaunt Family. The Gaunts were direct heirs to Slytherin himself. Head Boy and Prefect for Slytherin. You caught Rubeus Hagrid petrifying students in your 5th year and had him expelled. He was a third year. After Hogwarts you graduated with perfect grades and went on to work at Borgin and Burkes. There you worked until you disappeared, appearing a few years later under the name of Lord Voldemort. You gathered the Knights of Walpurgis, now called Death Eaters, as a political group who wanted to kill muggles before they killed us. You offered muggleborns and alternative- abandon the muggle world or die. They then twisted the story against you calling you a madman, and you were unable to accomplish your goals by politics; thus you moved on the violent revolution."
