Celestia has waited decades for this to come: her ascendance to the throne of Equestria, now waiting on her sister to come of age to join her. However, she is still young and unruly, not worthy to be leader of a country, much less its defender. Still, she will not be alone on her adventure to discover her destiny and her potential, with support from many.

As the Pillars of Equestria leave along with the young Luna, Celestia must come face to face with how inexperienced and unworthy she truly is, only helped by the brave Pegasus, Cordial Humility. Together, they will help transform Celestia into the ruler she is meant to be.

That is, if they can overcome the one obstacle that stands in their way: a new threat that comes from the stars, a threat made of metal, with intentions that are malicious and ruthless in nature.

Set before the events of MLP: FIM, and before much of the lore of the show. This is the story of how Celestia goes from a spoiled, arrogant mare, to the strong and wise Leader from the show.
