Alyssa looked around as Professor Scabior posed his question. Sure it had trapdoor that nobody knew about until now which made this place kinda secret but Alyssa figured that it served another purpose. So she raised her hand and said,"Professor could it be because this place is one of the highest points in the castle that it was often used as a look out point? I'm not sure but wasn't this one of the places that was used at the Battle of Hogwarts to spot intruders coming in the distance?"
