As the door creaked open light spilled into the dust filled air, the rays of light the first to fall upon this space in hundreds of years. As my eyes cast around the room I noticed walls of books, everything covered in that thick dust that lay suspended in the air. Then, something caught my eye, I took a few steps into the room to make sure my eyes were not deceiving me. I gazed at the floor, kneeling down to get a closer look. With a feeling of dread washing over, I realized that I was looking at a perfectly clear mark on the floor, two marks to be exact. Footprints. I was not alone.
