While arranging books in her library, Twilight Sparkle discovers an ancient looking book she'd never seen before. Upon opening it she sees that it's a journal that once belonged to Star Swirl the Bearded, one of the greatest conjurers who ever lived. What she discovers is that this is not a journal of old spells, but more personal stories of his past, and ponies that he used to know. In reading the journal, she will discover the origins of a malevolent tyrant, a spirit of chaos, a heartless queen, and even her own mentor and younger sister.

This is a stand alone story that has no connections to my TwiMacVerse. Cover image courtesy of google as I couldn't think of anything else for it.
