Obscurity

I will keep this part as short as possible. Before entering the world of this book, there are a few things the reader should know about that aren't readily apparent in the first few chapters.
First off, the reader is directly interacted with by the story, but they are not a physical presence in the book's world. You are an active observer of this world, and the characters know you are there. They know they are simply characters of a book and accept that without question. They have been waiting a long time for someone to read their book, they want to find out how this story ends just as much as you do. The characters have been repeating the same day over and over without change from the moment they were written until you arrive. With your arrival, the characters know that things will begin to change, and the story will progress. Some characters are happy with this, whereas others will be uncertain about your presence, and even downright angry at it.
Since you are not a physical presence in the characters' world, you cannot interact with objects, you cannot change anything and you cannot change the story as it is happening. You are there to offer a reassuring, comforting presence to the characters. You do not read their thoughts unless they want you to, but they can read yours. You never speak to the characters, but they understand what you are thinking.
