It is VERY recommended to read the Original Fallout: Equestria before! Most of the story revolves around it!
Dark Ages takes place in the foreign and cruel wastes of the once glorious Equestria, Gunner, an average lazy pegasus in stable 154, finds himself in the Wasteland after unknown mecrenaries were payed to attack his stable, this results in him getting caught between a seemingly endless war. Quickly after, Gunner learns about the current situation he's stuck in, and after making friends and foes along the way to his goal, the young pegasus goes on a journey to find out who he really is, and his life he never knew or wanted.
Note- Special thanks to Kkat for letting me use some of her original charcters in my story, this story does not considered canon in any means, most of the Original Characters in the story does not belong to me, so resembelnce or any kind of mention of charcter in other stories is completly possible!
