Celestia's True Story and Battle with Night Mare Moon.
(All By: nimaru)
Part One: The story begins...
Part Two: It's continues though bathtime. (I love the guard's reaction here.)
Part Three: The monster within and Celestia's attempt of rescue.
Part Four: The Final Part and Harmony returns... for now. (Once again, the guard's reaction caught my attention.)
This story is drawn extremely well and in truth I shed a tear every once and while during parts. It's a great backstory for the princesses.
