A Library Adventure

Walking inbetween the book stacks, you look around as you go but see and hear nothing out of the ordinary.

Turning a corner, you see movement in the corner of your eye.
You pause, wondering if it was just your imagination.

To your left is a closed door leading to a teaching room.

Further along from that is the door to the stairs and lift.

In front of you, there are empty desks.

To your right, where you thought you saw something, are more books.
