Celestia had to dig through Enigma's effects – anything of importance would be stored away, kept for memory's sake. Unfortunately, the thing she finds is the last thing she would have wanted to see. It's a series of letters, unsent, with most directed to her from Enigmatic Insanity. They span the hundreds of years they knew each other, and the forty-something years when it was a one-sided relationship on Enigma's part. Celestia chooses to read them, but could never have believed their contents.
