Firstly, let’s dispel a few myths. You might have heard rumours about Slytherin house – that we’re all into the Dark Arts, and will only talk to you if your great-grandfather was a famous wizard, and rubbish like that. Well, you don’t want to believe everything you hear from competing houses. I’m not denying that we’ve produced our share of Dark wizards, but so have the other three houses – they just don’t like admitting it. And yes, we have traditionally tended to take students who come from long lines of witches and wizards, but nowadays you’ll find plenty of people in Slytherin house who have at least one Muggle parent.
