Deep within the castle, Twilight, there is a room protected by wards new and old, seeped with more protections than anything barring the Elements could break through. Inside is not a king, a tyrant, or even a weapon….
Inside, Twilight, is a book.
A book that is older than I, older than Discord, older than Equestria, even…
It is named the Atlas, but has no author. A fitting name, really; it is a written map of our world and everything in it. It contains more knowledge than the libraries of Equestria combined, but none of it is safe.
This is the story of The Atlas, and what comes of it.
