Sunset Shimmer really did not expect to wake up several years in past before she left through the mirror. Now she'll have to make due with her new reality, as well as two pestering princesses that won't leave her alone.
The rules of the game have changed; now, the multiverse has been born, but it is in danger of being extinguished. One spark can create a storm and one Sun is the key to survival.
For years, Princess Celestia faced the fact of Sunset Shimmer without a mother, and Sunset without a family. Luna decides it's time for that to change.
Sunset Shimmer has never needed anyone or anything - she had her magic, she had her ambition, and she had intellect. Others just stood in her way or held her down. So what do you do when your plans for world domination fall through?
After Luna's banishment, Celestia created the Angels: a team of three magical prodigies tasked with protecting Equestria and handling any task the Princess cannot. Given recent events, "wielding the Elements of Harmony" might warrant a mention too.
Sunset Shimmer has betrayed Celestia and entered the mirror to another world. However, the first day in this new world would change everything when an accident causes Sunset Shimmer to lose her memories.
