It's a library, doesn't seem to be a lot of books around here looking at the first few shelves. There is a fog blocking you to see any further in the room, and the ceiling looks to be long and everlasting, if there even is an end.
Daring to walk at all, every step results in a creak in the floor boards but there's the faint sound another set of footsteps behind a few shelves. Someone else is here.
