As the only daughter and future successor of Queen Galaxia and King Cosmos, Elementis is the rightful queen of Equestria. However, she was exiled long before she could be coronated, framed for a crime she didn't commit by her mother's talented student Celestia.
After her exile, she falls in love with a dragon. Together, they initiate the war between dragons and ponies, fighting on the dragon's side, to reclaim Elementis' throne.
After having a daughter, however, Elementis decides she needs an inside pony and her half pegasus half dragon filly named Fiera could soon fill this role.
When sent to a small town called Ponyville, Fiera meets several ponies who actually want to be friends. But these aren't any normal ponies, these are the children of the popular holders of the Elements of Harmony. Will they change her objectives?
