Many years ago, in the heart of Equestria's capital, Princess Celestia established the “E.U.P. Guard” during the anniversary of the first Celestial year of peace. One of Her Majesty's guards, Lasting Gravity, was very intrigued by magic. He beseeched the princess to mentor him. After much internal debate, the princess eventually decided to take the unicorn under her wing.

Lasting Gravity had been blinded by anger. He magically rose up from the cracked marble, with lustful rage in his eyes and a maniacal grin etched onto his face. Lasting began to laugh with a chilling and nefarious tone. Electricity danced about his body, cracking the walls and floor around him. He fired a blast of negative energy at the princess, breaking through her ethereal shield.

Lasting Gravity, like many before and after him, was defeated by the Elements of Harmony and would never again set hoof in Equestria. But even the Elements have their limits... Years passed and the elder princess lost her connection to the Elements. The lasting effects they once had on the world would now be reset as they came into the hooves of new ponies. These new elemental keepers would have to stop old threats returning... some more dangerous than others. The Princess had never considered the possibility that Lasting Gravity might return. Unlike most of her former foes, he was but a mere unicorn, with no unnaturally long life span. But his time beyond the boundaries of Equestria had given him ample opportunity to prepare new magic, magic that could allow a being to live without the need for a body... And so our story begins...
