Plot

To stop Nightmare Moon, Twilight Sparkle, Spike and some locals must find the Elements of Harmony.

After Nightmare Moon decrees eternal night, Twilight and her new friends venture deep into the Everfree Forest to find the Elements of Harmony, a set of artifacts used to defeat Nightmare Moon in the past. Nightmare Moon creates obstacles to stop them, but each pony helps the group overcome them using her own strengths. Once they find the Elements, Nightmare Moon appears and shatters them. Twilight realizes that she and her new friends represent the six Elements - Honesty (Applejack), Kindness (Fluttershy), Laughter (Pinkie Pie), Generosity (Rarity), Loyalty (Rainbow Dash) and Magic (herself) - and they wield them to defeat Nightmare Moon, returning her to her original form as Princess Celestia's younger sister, Princess Luna. Celestia returns, forgives Luna and allows Twilight to stay in Ponyville in order to continue studying the magic of friendship.

It is up to Twilight and her new pony friends to help the Princess, but it will not be easy. Night Mare Moon challenges the ponies with individual obstacles they must overcome to find the Elements of Harmony before it is too late.
