The Princesses of Equestria: Celestia and Luna, have realized that the safety of their ponies and every other creature of Equestria are in good hooves with the Elements of Harmony and decide that their eternal R&R has come at last.

Eager, the sisters decide to leave the six hapless ponies five days to prepare for their new roles as the leaders of Equestria, leaving Twilight, at the least, a bit shook from the whole situation.

In the meantime the sisters do get to have some quality time together. Alone.

While Twilight does her usual 'Twilighting'.
