Canyon Diablo is a reascendant Gomorrah.

With rail bridge construction halted by hellfire and tragedy, and railroad companies warring with local land owners to complete it, the town becomes an open boil on the Arizona Desert.

Gamblers proliferate. Prostitutes ply their trade. Brigands roam on the roadways, waylaying the innocent for an unknown purpose.

Gunfight after gunfight. Coffin after coffin. Legend soon grows of this phantom of the high desert.

A lone pistolier dispensing God's judgment. A one-man vendetta ride, wielding a strange mechanical weapon of the Old World. Baptizing the heathen in hails of gunfire.

Eventually, folk find a name for this masked missionary of death...
