When raiders attack Stable 45 and kidnap his sister, Chief of Stable Security, Shadow sets out to track her down across the vast wastes of the Equestrian south west and, if possible, save her. Along the way he uncovers a threat most ponies had forgotten, or thought long since destroyed in the war. Can he and his friends stand against the gathering evil? Or is the wasteland doomed to fall forever, with no hope of ever rising again?
