Equestria is wrought with a Plague. The Pastromorbo Nostrae, a virus which eats away at the psyche of those it infects until all they know is wrath and bloodlust. Although the Plague brought Equestria to its knees, the city of Canterlot remains as the final bastion of civilization; its denizens work around the clock to ensure that the Facilities, i.e. centers of research, scattered throughout the outside world are equipped to find a cure.

The Equestrian Winged Corps stands as a remnant of the one-mighty Equestrian Armed Forces, its function now relegated to ensuring that the Facilities are well-supplied. Three soldiers of the Corps are tasked with delivering a replacement for the broken water purification chip at Facility Thirteen. Standing in their way are miles of desolate wasteland which teem with bloodthirsty marauders made mad by the Plague. They must do their duty. The future of Equestria depends on it.
