"Did you say that you don't know Lord Voldemort? You haven't heard of You-Know-Who? So you came to this page to see what I'm talking about? That explains everything! He-Who-Must-Not-Be-Named is the worst wizard alive! He kills people he does not like and gets his followers to kill some people. And if the followers who betray him get killed, and lots of other innocent people too. Like your parents. He's been strong a long time, until you came, Harry. The boy who lived."
