This Equestria, a different Equestria where Luna never became Nightmare Moon. Instead Celestia succumbed to her desire for everlasting peace in a world of light was twisted creating Daybreaker.
After a massive battle Luna emerged victorious thanks to her friends who the elements bestowed immortality to.
Now a millennium later Daybreaker returned and was defeated by Sunset Shimmer, Luna's student and her friends: Spitfire Flare, Strawberry Sunrise, Coco Pommel, Nurse Redheart, and Trixie Lulamoon, Also her dragon assistant Ember.
A year later an ancient order devoted to the worship of Daybreaker seeks her Resurrection and is using Sunset to do it, however the ritual is interrupted and a mysterious and odd young filly named Helia is created. Now its upto Sunset who happened upon the creature in the Everfree Forest to protect her from the cult and from her own past, all in order to see to it the crimes primordial to this innocent, yet somewhat bratty young life are not the catalyst to usher in Daybreaker's Resurrection.
