Hell has an infinite library. Twilight wants to use that library. There goes the neighborhood. Yep, right out the door, and it’s taking the couch with it.
When one fateful search through the Everfree Forest leads Rarity to a secret library inhabited by the spirit of an ancient alicorn princess, she realises that it may be time to start believing in fairy tales.
Rarity enjoyed the simple pleasures of life. Drinking tea, fighting timberwolves, picnics with Fluttershy, meeting dragons and, most of all, spending time with an ancient alicorn spirit. She wouldn't give it up for anything in the world.
