Through it all, Twilight Sparkle had kept up a near-constant monologue, telling Erin all about various features of Canterlot. She went into a lot of detail on the Royal Library, which apparently housed the largest collection of knowledge anywhere in the world. She talked about the history of the Royal Equestrian Orchestra, and the Orchestra Hall where most of their concerts were performed. She talked about her favorite hangouts as a filly and as a young mare, and what it had been like going to school at Celestia's School for Gifted Unicorns.
