From publisher blurb:
Stranded on Distant Moons,
Threatened by Alien Technology,
Only Courage, Wits and a Sword,
Against a Hostile World.
In the paleolithic an alien race, the Archon, kidnapped cavemen and took them to the Moons of Kerogo. In these laboratories they were twisted as the Archon tested the genetic plasticity of our race and others. Then the Archon warred with an enemy they could neither defeat nor stop. After the Archon's extinction the humans and other races escaped the laboratories and preserves to spread across the surfaces of the moons.
But the escaped races relied upon the technology of the Archon to build their civilizations. As the devices wore out every generation saw the slow retreat to barbarism and savagery. In the last age an expedition accidently activated a comatose Archon AI. It ordered Living Metal, its robots, to restore the laboratory moons of the Archon. to capture enough specimens of the escaped races and exterminate the rest.
In the genocide some managed to escape and reach temporary refuge. But Living Metal continues to restore the moons. Mankind can only hide for a few more generations before he is again hunted. Many humans are hiding as savages. The civilized ones are in warring city-states.
Mankind needs men of vision. Men who can forge empires where art, science, technology and the tools of war can be created to fight the Living Metal of the Archon. It is a time for heroes...it is your time.
