The Unlikely Inquisitor

It is the dawn of the second millenium.

For ten centuries, the immortal demigoddess Princess Celestia has ruled over the Empire of Equestria.
She is the master of mankind by the will of the Gods and the master of the land of Equestria by the might of her indefatigable armies. She is wreathed in magic from the dawn of time, magic that few people understand and even fewer can replicate. She is the undisputed ruler of Equestria, held in awe and reverence by the majority of her subjects whilst she rules over a supposed utopia of love and understanding. She is the master of the sun, who has sacrificed everything upon the altar of her empire so that it, and she, may never truly die.

Yet, even in this age of harmony, the winds of change are blowing as the ageless demigoddess maintains her eternal vigilance. The resurrected Princess of the Night has resumed her place at her sister's side, and the newly discovered princesses Cadance and Twilight Sparkle have likewise taken their fated places at the side of the ageless Celestia. On the borders of Equestria, armies stand in nervous silence as the continent outside their borders burns. Yet within, heresy is being given voice as cults are formed dedicated to the veneration of the ancient and terrible spirits that stalked the lands of Equestria before they were banished by Celestia's armies.

Outside the borders of Equestria, hungry eyes stare inward at the peace and prosperity of its inhabitants and rub their hands in avaricious glee at the thought of all those riches swelling their coffers and war-chests and beyond the furthest star, beings that once roamed the wildernesses of Equestria are eyeing territory that was once theirs and are looking to reclaim it. Among the darkest corners of Equestria, hungry eyes open as hydras, timberwolves and other dangerous beasts roam the empty wastes.

Standing against this threat is the ever-vigilant Inquisition, its Ordos standing ready to stamp out any hint of the foreign aggressor, the mutant or the heretic. The Inquisition is split into three major Ordos, the Ordo Malleus, dedicated to combating the perils of the arcane and those dangerous sorcerers who have thrown their lot in with dark powers, the Ordo Xenos, dedicated to eradicating the dangerous beasts and mutants that wander the lands and lastly, the valiant warriors of the Ordo Hereticus, dedicated to stamping out the forbidden cults and those who would overthrow the rulers of Equestria by any means. Conducting their battles from the shadows, the reach of the Inquisition is long and its eye is ever watchful, yet even these stalwart defenders can barely keep in check the ever present threat of monsters, heretics, and far worse.

To live in such times is to live in a golden utopia that is built atop the backs of countless heroes who have fought and died in the shadows. It is to live under the gaze of one of the most powerful surveillance networks imaginable. This is a tale from those times. Forget the magic of friendship, for betrayal waits around every corner. Forget the elements of harmony, for they have surrendered their power for the greater good. In the grim shadow beyond the gaze of the sun, there is only death. There is no peace in the long night of Equestria, only silent slaughter and the laughter of thirsting Gods.
