The Mojave; hardly touched by the bombs of the Great War and home to the city of bright lights in the desert wasteland. Two hundred years after the Great War, though, the Mojave was subjected to the warring powers that resided in it.

The New California Republic, a democratic military in California, wanted to claim the Mojave Wasteland for themselves with good intentions, but never quite seeing them through, while Caesar's Legion, a ruthless slaver society, wanted to forcibly convert the Mojave into the Legion, controlling the Wasteland. A four year war waged over the Dam, until the Courier came.

Some say he was a warrior from one of the tribe's Caesar conquered, others say he was a ghost, only out for revenge on the men who shot him. In a matter of months, he defeated both powers and left them as shadows of their former selves. Both armies were weakened and tossed from New Vegas, ruling over the Mojave.

It's been three years after the Battle of Hoover Dam, and the Republic continues to hunt down the remaining bands of Legion, but there's something far worse than them: a threat from years before them all and one more powerful then they'd ever imagine. Without the aid of the Courier and his army, the Mojave will need to stand for itself, together as one, or let their greed of the Mojave be their downfall.
