Fallout Equestria: Nightmares's Path

Does the moon rise or set? Do daydreams rise and fall? Every dream is said to be light as pure as crystal. Yet darkness may lurk at every shadow and devour the light. Only to turn them into a worthless wasteland. The two Princesses have always been known to keep peace, harmony, and order in Equestria. Yet nopony ever predicted for another conflict to arise. Once more, The Two Sisters have drawn a struggle to power, but what's different is Celestia now being the dark shadow of this battle. With the two sisters locked in combat, this paved a way for the ponies of mere Equestria to break. But some ponies had plans to break all ponies and Equestria itself. It did not take long for any pony to set off and create "The Crater of Nightmares." The sky lit brighter than any fire or shine, leaving many ponies to perish, shelter, or be radiated to change or die. As quickly as the bombs dropped, pony society fell. What a handful of salvaged in the aftermath knew nothing on fixing this "Fall." What seemed to be an eternal nightmare, was a dream come true for many. Including one dark and negative stallion. As he takes his path through Californeigh, he finds happiness l, but doesn't realize all it is, but a simple, dark nightmare.
