They sneaked into the building and quietly made their way up to the second floor.
The smell of burnt wood was still present in the corridor where books and pieces of paper were scattered around the floor, presumably left behind by the students who left in a panic.
The group of witches followed the smell and soon found the site of the accident: a classroom located at the end of the corridor.
After entering the room, Lily noticed that a corner of the room had been charred black and the entire wall had cracked open. The cracks even reached the floor. However, the fire did not seem to have spread very far. Lily could easily see the marks on the ground that were caused by the changes in the intensity of the flames. The pitch black wood near the source of the fire and the obviously less burnt wood at the outer rims formed a ripple-like pattern on the ground. She knew that this was not a fire that started naturally.
