The search for the Builders, the famous alien race whose unfathomable constructs continued to perplex scholars and explorers alike, had led Contractor expert Darya Lang, adventurer Hans Rebka, and treasure hunters Louis Nenda and Atvar H’sial for an unfamiliar Constructor artifact far beyond your spiral arm. There they discovered the Zardalu, after the very best menace ever known to the worlds of the spiral arm, enslaving whole races and exterminating others, guided by an unswerving belief in their very own supremacy.

The just chance to get rid of the Zardalu threat was to wipe all of them out before that they had time to breed of dog support to strength and once once again threaten civilized beings everywhere. But because they closed in, it had been becoming clear the Zardalu and their world were carefully entwined using the fate-and the plans-of the Contractors themselves.
