Hogwarts School of Witchcraft and Wizardry discussion

Occasionally, I will be adding trivia questions relating to the beautiful wizarding world of Harry Potter and friends! These questions won't be easy. Nowhere will you find a question like 'what house was Harry in'. No, not here. Here you might find a questions like 'What was Mr. Olivander's first name', but that's just about as easy as it gets.
Of course, let's explain how to play!

I will add the question, and those who believe they have the answer will comment with said answer, and they're house. You can use your Pottermore house, or your most used Charrie's house. But please choose one and stick with it.
One member can answer multiple questions, but give others a chance too, please?
And finally, winner of each question will award 50 points to their house unless a bigger point score is listed for some questions.
Okay. If you might have any questions about how the game works, we accept trivia question suggestions also, message me!
