To my most faithful student, Twilight Sparkle's Skin,
Don't worry, she's visiting Canterlot this week. It turns out she's quite loquacious when given a spell to synthesize vocal cords, and she's given me a rather fascinating insight into your daily life.
I am really very impressed with your spellwork, but less so with your problem solving or risk assessment. We'll be visiting Ponyville once the week is up, as I am greatly enjoying your skeleton's company - after the initial confusion of course.
Your loving mentor,
Princess Celestia
