When Princess Celestia is unable to cheer up her mopey little sister, she leaves a copy of her favorite play in Luna's room as a last-ditch effort to ease her melancholy. Luna takes the bait, and reads the story. What comes next is a mad tale of lunacy, obsession, politics, gargoyles, and hypochondria. Will the palace survive Luna's reading session? Will Celestia?
Thanks to William Shakespeare and Miguel de Cervantes for the inspiration. I am sure both of them are currently rolling in their graves.
