Princess Luna's return from her thousand-year exile on the moon has been one punctuated mostly by elegance. However, some things plague her heart about the new cultural standards of the realm, and its conflictions with her past actions. Eventually she breaks her silence about the coerced unification of early Equestria to none other than Applejack. Her honest depiction of the past runs contrary to the narrative that Celestia has put forth in the thousand years of her absence, and the truth the matter threatens to unravel Celestia's friendship with Applejack and her friends.

Especially as more is uncovered about how much Celestia has slowly erased from the history books.
