664 years after Tirek's defeat. Equestria is a barren, dusty wasteland of burnt hills where humans have taken residence along with some ponies.

Those humans and ponies live independently of the Solar Republic, a gathering of several city-state.

However, when a pony/human hybrid of royal blood and his childhood friend, also a pony/human hybrid who has a crush on him, get involved with the Solar Republic, things will go out of hand as dark schemes are exposed and a new evil, helped by an old one, makes itself known.
