It has been ten years after Nightmare Moon's banishment. And every year the ponies celebrate Princess Celestia's victory against Nightmare Moon with the Summer Sun Celebration. Celestia on the other hoof, hates the festival but participates in it to keep her subject's minds off of the deaths of the ponies dying in their nightmares.

Meanwhile, the pitch-black creature arrives to Equestria and sets its eyes on finishing off the pony race by attacking the Equestrian capital, Canterlot.

With her sister banished to the moon, Celestia believes she will have to face the threat alone. But an unexpected ally will come to her aid to protect the pony kingdom.

The OC tag is there for the OCs that will play small roles in the story.
