Garand, a Pre-War Gryphon of the now defunct Steel Rangers Corps of the Equestrian Armed Forces, sets out to the deserts of New Pegasus in search of a new life and to bury his past in the ashes of the new world. Soon though, that past will come back to haunt him. With the Steel Rangers of the Post-War era out for his blood and Bounty Hunters and Hitmares alike gunning for the price on his head, everything he had learned fighting the Zebras of old will be put to the test. It was time for him to tear down this twisted facsimile of the Corps he had once honorably served and rebuild it anew. And with some help along the way, he just might see that come to pass.

(This is set within the universe of Fallout Equestria: Lone Ranger and will crossover at points)
