Mortal Equines

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

...great, hungering cities, behemoths of steel, iron, bricks and wood, the offspring of Earth pony sciences and Unicorn magic, roam the once pristine, perfect continents of the world. Where once there was endless greenery, much of the land is now reduced to a dusty wasteland. Forests have been harvested to extinction for fuel, and the flames of war have flared and guttered in the countless centuries since the disappearance of Equestria’s diarchs. With the mobilisation of the cities and towns which once helped each other, Equestria has been transformed into the Great Hunting Ground. No city dares to call for aid, lest the ones they call descend upon them, forming a truce with other settlements long enough only to satiate their hunger for resources. Ponies watch the horizons with every waking moment for glimpses of smoke, the tell-tale sign of predators... or prey.

Not all ponies, however, took to the tractionist way of life. Many Pegasi chose to remain ‘safe’ in their cloud cities, far above the squalor of the Earth. Gryphons stuck to their high mountain peaks and aeries, where the cities could not climb to consume them.

And a few ponies opposed the evolution of their conurbations, seeking to live static, clean lives. Easy prey for the cities, or so most of them were, for a while...
