Nightmare Moon may be stuck in the Celestial prison but that doesn't mean that she won't be rehabilitated. After all she needs to be civil with her Co-Regent doesn't she? But how can she and Celestia be civil if they are millions of meters apart. Simple, letters.

Luna, princess of the night, is in her bedchambers, ready to go to bed for the next night. She lays on her bed, wondering, what if I was the eldest sister? What if Tia was banished to the sun? What if I ruled all?
Celestia, princess of the sun, is at Twilight Sparkle's new castle, helping her set up her new library. She uses her magic to teleport a book, labeled, "Alternate." She opens it to find a spell to switch her sisters' duties. Without thinking, she takes it home, only to see that she is the younger sister.

“In a thousand years, our love will still be here.” Chrysalis whispered as she stared up at the full moon, an imprint of a mare appeared on the surface. She placed a hoof on her chest and smiled. “Always.”

Not many ponies know that Queen Chrysalis was there in the beginning. She promised Nightmare Moon their love will remain until she is freed from the banishment placed upon her by Princess Celestia.
