Discord and Queen Chrysalis have teamed up to corrupt Princess Celestia in order to use her power to overtake Canterlot and eventually all of Equestria!  Princess Luna herself is unable to fend of the trio of heavy-hitters and is forced to flee the castle.  She must turn to Twilight and her friends to stop this madness before it spreads any further.  Knowing that the gang is much weaker without the Elements of Harmony, Luna bestows her armor to Spike to have him forge individual necklaces and a ring for the gang and himself.  These charms may not equal the might of the Elements of Harmony, but they are still extremely powerful; imbuing each pony (and Spike) with their own individual abilities.  They must rally all their friends to retake the castle in order to even have a chance at getting to the throne room where Discord, Chrysalis, and Celestia await.  Will their teamwork and newfound abilities be enough to defeat Discord and Chrysalis to return Princess Celestia to normal or is Equestria forever doomed?
