Only a few years earlier, we experienced the LastWar, which devastated the Earth and everything that lived upon it. The cause of the War is a mystery; it was impossibly brief and no one who survived knew the details.
In the years following the cataclysm that ensued, the few scattered survivors of Old Earth struggled to scratch whatever living they could out of the radiation-wracked ruins of their former world. It wasn't easy. The oceans had dried into vast salt deserts, dotted here and there with a few fetid pools. Plants and creatures now mutated at a terrifying pace into increasingly dangerous and alien forms. In the midst of this desperate fight to survive, memories of the old world faded away.
There were a few, though, who remembered. Amid this chaos arose an order of survivors, who came to be known simply as The Wanderers. They sought to reclaim the knowledge of Old Earth and spread it to the scattered tribes, to replant seeds of knowledge that had been lost and fight for the future. They alone braved the vast wastes separating these far-flung oases of humanity, fighting for those in need, trading, and teaching. With them came a new hope for this struggling world.
Now, a new threat has arisen. It had been thought that the robots of Old Earth; those who had survived the attacks at all, had long since run out of power. Suddenly, Wanderers began to discover oases that had been slaughtered en masse, and those few who survived described armies of mechs marching out of the wastes, killing everything in their path.
The Wanderers now accepted a new mission: to find the source of this new evil, and to destroy it. As a Wanderer, this is now your mission as well.
