Roget was a backward world, yet important to the Company as a Free Trade Port. It was up to Agent Tito Ren to keep that culture stable and the Port free of expensive strife - in spite of Rogetians like the "Imaiz," self-styled Wizard of the great city of Anharitte, and his meddlesome social tampering. But when the "Imaiz's" activities became known, all the well-meaning Tito Rens in the Galaxy couldn't stand between Roget and Free Trade warships. It was up to the Wizard of Anharitte and his uncanny abilities to defend the world he was reshaping.

The Star King had bet on Colonel Bogaert's ability to survive...and the fate of Terra was at stake!

Smoothly, remorselessly, inhumanly, the controlled flow of people continued. As each of the great planetary shells approached population maximum, the surplus of mass of humanity was transported out: Mars shell, Asteroid, Jupiter. Inexorably they filled the space made ready for them by Zeus, the master-minding intelligence. Jupiter shell, Saturn, Uranus... But at Uranus shell the ordered, ever-outward flow stopped and the pressure of the countless billions had pushed the shell to the very edge of catastrophic breakdown. Beyond Uranus lay ready Neptune shell. Zeus-designed, Zeus-built but no longer Zeus-controlled. Another giant intelligence had usurped all power, was refusing to operate the system that alone gave any future to Solaria. And so it was that Maq Ancor, Master Assassin, Magician Cherry and Sine Anura became the eyes of Zeus as they journeyed to the place where all systems failed, where chaos and the Tyrant of Hades ruled.

Mercury Shell, Venus Shell, Earth, Mars, Asteroid, Jupiter, Saturn. Each shell concentric, studded with artificial planets, each planet embedded in its shell, spinning like a ball-bearing. The whole Zeus-created in the service of Man but now beyond his control. Now mathematics and space physics, converging, suggested another shell, its existence hidden from Man. A shell of utter darkness, cold and silence where only extreme mutants could survive. To find that shell, the three were journeying again: Maq Ancor, Master Assassin, Magician Cherry and Sine Anura, Mistress of the Erotic. Together, daring the all-seeing, all-sensing hostility of Zeus.

A sunflare, a meteorite strike, a tachyon storm - all natural disasters - were wiping out the best brains of mankind at a rate of a thousand times greater than normal. The Director of ChaosCenter laid it out bluntly: "All our evidence suggests that a device that can alter probability exists. For want of a better name we call it the Chaos Weapon. Somebody, somewhere, wants us cut back - and hard. Unless we find that Chaos Weapon and destroy it, it's going to destroy us!".
