Celestia and Luna are a pair of sisters. They have always been known as a pair of sisters, since the time they went to study under Starswirl the Bearded himself. Yet perhaps over a thousand years ago, this wasn't always how things were. Sometimes, you have to keep secrets about the ones you love, even if you wish things could be different.

For the sake of the future, of course.
