After Hugo had been quite excited that they seemed to have destroyed Divination he had wandered off happily, only to find this place. He had been staring at it for a while and his Ravenclaw curiousness started boiling up inside him. He quietly pushed open the door, but it made a hard creaking noise. It was dark. Hugo took out his wand and whispered "Lumos." The tip of his wand lit up and he could see the classroom better now. It was empty. And dusty. How interesting. Perhaps this place could be secret and he could use it to practise his magic in.
