(This story is a direct sequel to The Mare that eats The Monsters, and reading that story is highly recomended to understand what's happening in this one.)

The horrors of that one night are still fresh in the minds of everypony in Equestria, even now, two months later. Hundreds of ponies were mercilessly slaughtered and Princess Celestia was killed by Luminous Horizon, her duties falling to her younger sister. Despite how confident she had seemed that her sacrifice would not be in vain, things have only gotten worse since then. The sun's light is begining to fade, casting the world into an unsettling eldritch abyss.

With the sinister omen of the sun's waning light looming over all of Equestria and the hunger of the fiends ever growing, Moonrise Drifter now pursues Luminous Horzion, eager for answers and vengance.
