"There's no such thing as a purely happy memory of a lost pony; it will always be laced with a longing that shall never be fulfilled."
Princess Celestia is never seen without a kind, warm smile on her face. Yet, she's over a thousand years old...just over two thousand, to be exact. As an eternal, all powerful ruler, Celestia shows Twilight a secret room and prepares her to deal with inevitable loss. Afterall, as a powerful unicorn, Twilight will also outlive many ponies. She also shares many scenes from her life, to show her faithful pupil exactly what it's like to be her. But why, exactly?
