Even in Equestria, power can be the ultimate source of greed.

When Luna takes over the dominion of Equestria in the qualm of the New Lunar Revolution, the land falls into eternal night. The mane six (Twilight, AJ, RD, PP and Rarity) have all gone their separate ways since their beloved Princess Celestia was brutally murdered.

Celestia, before her death, sends Twilight on a special mission...a mission crucial to the future of Equestria. When Twilight fails to complete it, consequences are sure to follow.

Several years pass and Twilight, now an older and wiser mare, founds a rebellion simply knows as the Resistance, or the Celestial Resistance to some. It is her goal to see that power is restored to the rightful place. She believes Princess Celestia is still alive, and will return to seek justice upon her land. Until then, Twilight has recruited the assistance of other unicorns, namely one in particular. Star, a young, wayward unicorn filly, becomes Twilight's reluctant apprentice, unwilling to admit that she has the potential to be a powerful unicorn.

Meanwhile, the New Lunar Empire has done some recruiting of its own, fearing an incoming uprising. A now older, more hard-edged Rainbow Dash, or Captain Dash as she is now known as, is the leader of the Lunar Force--Luna's army. She has started recruiting several pegasi for the army, especially one she sees great potential in. Nova, a young pegasus filly who has been a homeless rogue all her life. Rainbow takes her in as a "Recruit under Special Circumstances" as new recruits normally would have been drafted by their age.

The rest of the story revolves on following the two young fillies (Nova and Star) on their training and their learning about what happened to everypony the day Luna decided to take over. They grow up in opposites sides of the war...never knowing that they might share something very much in common.
