Long before the megaspells, there was a mare born by the name of Polly Brain. She by far was an incredibly intelligent and talented Mare when it came to science, machinery, mathematics, and many more subjects that would define part of who she was.

However thanks to her childhood being filled with being bullied, not having many friends, her parents seemingly ignoring her very existence, and it seeming like nothing would go her way, she'd always want a chance to get revenge on the worlds ponies who dared wrong her.

Her Chance would actually come quite soon as by age 18 she was hired by Stable Tech, rapidly climing the ranks as she proved to be an invaluable asset to the company. It all culminates in Stable Tech giving her what seemed to be the most perfect award she could have asked for, and alongside this she managed to perfectly calculate when the Megaspells would drop 1 year in advanced, giving her the time she needed to concoct the revenge she wanted so bad, and to start her life anew as a goddess.
