Banishment.
Such a powerful word with such a simple meaning. A word most ponies never hear in their life...
"Twilight Sparkle,"
A simple word meaning to be sent away as a form of punishment...
"You have been proven guilty,"
But I haven't done anything wrong, have I? Anything to deserve to be punished? Being framed? Is that a crime?
"You are banished from Equestria,"
Why would they all just give up on me? I know the truth, but they refuse to hear it. Why won't they just listen?
"You are required to leave at once."
Just listen.
Before war overtakes us all.

Give cover art respect where it is due, meaning this guy.

It has been two hundred years since Celestia’s funeral, and Equestria has changed. Mighty ships sail between the stars, great cities scrape the skies of half a dozen worlds, and what was once a humble nation has become a vast empire.

And now, Twilight Sparkle writes to her dearest mentor once again.

As of Season 4, LttS is fully re-integrated with canon.
