Equestria has fallen. The New Lunar Republic stands in its place with Nightmare Moon at its helm.
Nightmare Moonβs beloved daughter, Eris, is devastated after her boyfriend breaks up with her. Luckily for Eris, her mother is the darkest entity known to ponykind, and though the sovereign of the night is a cruel ruler, she is fiercely protective of her daughter. Nightmare Moon is about to teach this colt a very important lesson: Never, ever mess with the daughter of darkness.
