Fallout Equestria: Last Breath

Once upon a time, in the magical land of Equestria...

The brown, rugged land once called home manifests the corpses of long dead stallions and mares. The mold growing on the ceiling of barely intact buildings, the gray grass sticking through holes in structures. The world was left as it remained when the megaspells were detonated. The lucky few individuals were given a chance for prosperity, a safe haven. That, is if you called a void of grayness a safe haven. These last remains were called Stables, state-of-the-art fallout shelters built by Stable-Tec to "ensure" safety. However, many social or mental experiments conceded, corrupting the Stables.

Eventually, some stables were opened up, re-colonizing the rotten ground. However, disagreements were generated and violence soon reigned all around the now-named Equestrian Wasteland.

Some stables were never opened, in a direct fact of experiments. Many residents were infused with untrue propaganda that they chose to believe. Because that's what their parents were taught, and their parent's parents. It must be true. Simply put, there was no life, that Stable was the only one left, you were the last ponies alive, the carriers of a burden to help your kind. That's what they believed.

Nothing could make them think any different.
