From publisher blurb:
The planet Eniran, in the Sonora sector, is a jungle world that few travelers choose to visit. There are rumors of an ancient civilization that once carved cities out of the thick jungle canopy. This culture has long since died away. The current residents of the world are primitive natives who trade very low tech trade goods to the traders who occasionally visit this world.
Recently, however, one of these traders acquired an extremely high tech communications device from one of the natives. Apparently this native found this device in one of the caves deep in the jungles of Eniran. The native called this place the “Temple of the Ancients.”
For many years members of his tribe sent their young boys to places like this in the jungles to prove their manhood in a coming of age test of bravery. The goal of these tests was for the native boy to bring home some object or artifact from one of these places of the ancients as proof of their bravery and willingness to face danger. Many of these young boys never return.
The travelers are approached by Emma Sato. Emma is a merchant officer aboard a far trader and is the person who acquired the object in question. She wants to find out if there are more of these kinds of ancient alien artifacts available in this “Temple of the Ancients.” She offers a proposition to the travelers. Visit this world and find this temple. She will sell the artifacts quietly without raising interest from other potential competitors or legal authorities.
