Far off in the distant north, beyond even the Crystal Kingdom's reaches, a lone city sits at the edge of the sea, one of the last of its kind. Cicero, a city still standing from the time of the original Crystal Empire, before the rise of King Sombra, lies practically untouched by the outside world. But an assassin of unknown origin seeks to bring upheaval to the city, and begins murdering several important political figures. Princess Celestia sends a marshal, one of Equestria's finest soldiers to get to the bottom of the mystery. This pony must delve into a hive of scum and politics before reaching the end. But what he finds may not be what he wants to find. After all.

We fear the dark for a reason.
