The Progenitors are long gone, but their technology and culture live on. Trillions of beings from hundreds of species speak the Progenitor language, eat Progenitor foods, and use Progenitor technology. The backbone of this society are Hoppers - smugglers who transport goods through the dangerous dimension of the Void.

The crew of the Discordant Note is on another routine job when they come across a member of a species nobody has ever seen before - a human. He has no memory of his past, his culture, or of the world he came from. What does he remember? He knows how to operate a multitool, fire a blaster, and how to kill a Sarcorian with his bare hands.

Now, the crew and their newest member must steal a powerful ancient artifact, evade the clutches of the powerful Encephalon corporation, and discover the truth about the Progenitors.
