Ravenclaw ,I guess.
Then again, it's been ages since I read and watched Harry Potter, so...
A small abandoned dojo to the east of the castle, from whence I could hurl insults at those dumbasses who keep falling off their brooms during quidditch games.
Proudly the colors of Gryffindor.
Never read or saw HP, but I was told I belong to Ravenclaw.
