Tomb Stone, AZ April 4th 1870, the start of the 2nd American civil war. After only 5 years since the end of the 1st American civil war, a 2nd civil war dooms the new nation to collapse, or did it? Agents, arm yourselves with a pair of 6 shooters each. There's a big mess in the timeline. And were going back to fix it old west style, at the end of a gun.
