Equestria, better known in the past as Sigmus IV, was once a bastion of evil but that changed during the holy crusade of the Night Sentinels led by the Doom Slayer. Millions of years have passed since those dark days and new life flourished, ignorants of the evil buried beneath them.

But destiny is a bitch sometimes. Calling back once more the ancient powers who fought in the past, Equestria will be dragged in their war. Sides will be chosen, but in the end, the Slayer will Rip and Tear, until it is done.
