A magical cataclysm crippled the world nearly destroying everything that existed. The only thing that remains of the civilization believe to be known as Equestria is rubble and chaotic rifts in space capable of mutating or destroying anything that goes through it.

The ecclesiarchy rules this land, the Inquisition ruthlessly hunts down unicorns who practice unsanctioned Magic, and any other non Pony or lesser Pony species that are a threat to their great Empire.

The grand patriarch of the Sun, High priest Mercury Thrumble sits at the head of it all, and what happens when one of his finest students discovers an inconvenient truth about the "God" of the Sun, the same evidence her father once found. Will she seek the truth above all else, or discard it as heresy to keep from her father's fate.
