Before Twilight Sparkle came to Ponyville, Lily Lightly was the librarian of Golden Oaks. Lily was a bright and happy young mare, who wasn't the enemy of anypony and loved the beauty offered by rural Equestria. She was a hard-working homebody who was always eager to sort through the latest book-cart shipments.
One day, Lily Lightly stumbles across a secret in Golden Oaks Library. It threatens to undo everything she knows about Equestria. Suddenly, Lily Lightly isn't everypony's friend any longer, and dark whispers are reaching Canterlot...
Ten years before the one thousandth Summer Sun Celebration, she vanished without a trace.
