In the dim past of what is now called the Black Years, mankind had built a world of wonder and glory. The world had consolidated into several mighty nations, and seeking new frontiers, man had set out to explore the heavens. What catastrophe could devastate such a powerful people none now know as the events are buried in the ashes of destruction? Legends persist, of course, but the truth of these may never be known. Some hold that Man became too proud of his accomplishments, and the forces of the cosmos sought to teach him a lesson. Others propose that wicked men came into power and chose a path of conquest. Still others believe it was all the result of a colossal mistake!

Whatever the cause, nation rose up against nation and deadly war was waged. Awesome weapons of destruction scoured the earth, deadly lasers, dread atomic bombs, chemical and biological agents that dissolved flesh, all did their terrible work. Oceans boiled. Continents buckled. The skies blazed with the light of unholy energies, millions died. Once a planet of over a billion human inhabitants were reduced to less that 100,000 scattered about the remain landscape. By the time the violence subsided, the very face of the world had changed. Mountains had fallen. Rivers tamed for hundreds of years raged wildly through broken dams. Not a single city remained intact. Continents had been destroyed or drastically changed forever. The Black Years descended.

But the world was granted a second chance, a legacy to all the creatures of Earth. To survive the deadly wilderness, one had to either learn to resist the earth poisons or to adapt to them. The few who found the means to resist continued the pure strain species of man. Most plants and creatures changed and adapted to the awful new world. And with those changes, the creatures of the world realized new and great-untapped powers. Many gained intelligence and discovered amazing mental powers never before known. The world witnessed the birth of countless new and sometimes violent species.

This then is the way the world is. It is a land of brooding, gigantic forests, wild unbroken plains, and rugged mountains. In places the wilds give way to man-made deserts and death lands. The ruins of the past dot the landscape. In this world, nature is merciless, death is quick, and strangers are regarded with caution and suspicion. Scattered across the continent are tiny settlements of intelligent creatures and those pitiful remnants of ancient America’s society who still survive, scratching a precarious living from the hostile land. Their only hope is to recover the glory of the past, to rebuild society, to restore the age of wonder and prove themselves worthy heirs of mankind. For somewhere, out there in the Great Void, awaits the brothers of this world. If only the intelligent races can mature from their barbarism, and escape the wilderness, then they may at last be welcomed into those lost Worlds of Man.

In the place of nation, small villages are born. Once there were kings and presidents, now only overlords and village leaders. Bands of mutants roam the wastelands killing and pillaging. Several cryptic alliances have emerged from the darkness. Some made up by “true” humans others by mutants only. Some seek to live in peace other to rule all. This is the world that was created by hate and arrogance. This is the world you were born into and must fight to survive in.
