The armies of King Sombra have been halted at the Crystal Front. The Crystal Empire and Equestria clash with a daily death toll in the thousands, deadlocked at the front lines. This is a story of those who fought to defend their homes against an unrelenting foe.

A very frightened, lonely, and unprepared Twilight Sparkle finds herself the target of King Sombra's terrifying bands of mercenaries and monsters on her way to the Front.

The good news is that she has help.

The bad news is that her help is a squad of the Damned: the worst of the worst, ordered to fight without cease until they die as penance for past crimes.

The worse news is that Twilight has someone in her head, someone that King Sombra is very eager to acquire.
