Following the events of A Return to Form, Luna has been restored to her natural power and status alongside her sister. They have even managed to make up with their estranged older brother, Terra. With the newest addition to their family in the form of an artificial filly Nightmare Moon life promises to be interesting. But an offhand comment by Terra may prove that words are truly the most powerful of tools. Now Celestia has decided to revive an age old rivalry with her sister, the royal prank war! Can Equestria survive their antics? More importantly, can Celestia survive the dark duo of Luna and Nightmare Moon? Armies will be raised, shadowy plans enacted, and dignity will suffer in the sister's quest to be able to leer at the other and proclaim, "Gotcha!".

The Elements of Harmony were unleashed against Nightmare Moon in a climactic clash, as was predicted a thousand years ago. With Nightmare banished and Princess Luna restored, life in Equestria is fairytale perfect. But just what was the relationship between Luna and Nightmare Moon? Was it as simple as the old books portray, or was there something deeper going on?

When Luna joins her sister in Canterlot Castle truths will need to be revealed, and the shadows of history rolled back. Sisterly harmony will be at stake, and trust will be tested in the aftermath of the return of the mare in the moon.

My first fic. If it ain't obvious as you read along, I am not a pro caliber writer, although I do try for proper grammar, spelling and the like. I will add chapters as work/life/free time permits me.
