Ravenclaw

HBO unveiled redesigned Hogwarts house crests for its Harry Potter series at a Back to Hogwarts event in Australia on Monday. They are flatter, thinner and circular where the films were heraldic. One change is a genuine correction to the books; the rest have split the fanbase.

While Slytherin house typically takes the blame for producing dark wizards, the most psychologically twisted character in the wizarding world actually came from Ravenclaw and used charm to mask his sinister nature.
