She then meets one of the Crystal Ponies herself and confirms to the pony that the Crystal Ponies have been "gone a thousand years", while the Crystal Pony goes on to say she remembers nothing of the time before King Sombra's rule, and that she does not "want to remember" anything about the duration of his rule. None of the Crystal Ponies the main characters meet can remember much about their history. A librarian they meet can't even recall if she works at the library. The Crystal Ponies look glum and dull, and talk in low, monotone voices. Twilight Sparkle speculates that King Sombra's spell must have caused the Crystal Ponies to lose the crystalline colors of their coats.
