Arthur Rights is your average, run-of-the-mill mail pony working for the Ponyville Post Office. He leads a very simple life, mailing letters and reading his most favorite books. His life is so simple, one could say it's… dull. It's formulaic, even. But Arthur doesn't notice this, and he's far too content with his current life, even though he's completely lacks friends.

But his entire life is changed in an instant when he discovers a mysterious book on his bookshelf. Upon reading it, he discovers incredible information that gives him a whole new outlook on life. Was he really this lame and unimportant? Well, if the book was true, he's gonna set out to change that. As time progresses, he realizes the book's information changes to help him in some of his current situations, but after he finishes reading, it often leaves him knocked out… or worse. Now he must decide if he should keep reading… or possibly die.
