After the events of Camp Everfree, Sunset Shimmer and her human friends have new magical abilities at their disposal. What they didn't know, yet, they weren't the only ones who benefited from the increased influx of Equestrian magic.
An old entity, sentenced for its chosen path, was banished to the world of man and endured in silence. Its patience was rewarded. This entity wandered planes, known and unknown, in a time before the Pony tribes lived under one banner. In a time before the Royal Sisters ruled and the Ponies of Equestria decided to follow them and their ideals, giving the tribes the opportunity to live nowadays in a golden age of peace. An era where Friendship, Love and Harmony shall conquer all odds.
Secrets of ancient times are about to be revealed and ruins of forgotten ages are about to be awaken from their rest. The history of old shall stir its head. But no matter what may transpire, the challenge will be all the same.
This being will start a new age for humans, Ponies and all other races of both worlds. Only this time, the Magic of Friendship may not be enough to stop the incoming threats to the form of life as they know it.
It will confront all with the truth, even if they wished to forget.
It will make them remember.
The inhabitants of Earth and Equus will have to face new circumstances they never could have imagined before. In the process, it will be decided if they can overcome the changes, or be consumed entirely.
The Secrets of Equestria are waiting, ready to be discovered.
