Allegations On Jupiter

There are four intelligent species in the Solar System although only one originated there:

Terrestrials still inhabit Terra and have colonized the Moon and Venus, the latter partially terraformed;

extra-solars for whom Mars is habitable have colonized it and are subject to the Terran Emperor through a Duke of Mars;

Ymirites have bought and colonized Jupiter;

the representative of the Merseian Roidhunate owns an artificial satellite, the Crystal Moon, which, because it is in Jovian orbit, is in the Dispersal of Ymir, not in the Terran Empire.

A Terran or Merseian who wants to visit Jupiter radios that planet from a robot station on Ganymede. A Ymirite called Horx, piloting a material spaceship enclosed in a force-field, collects the visitors who are transported in a cabin with an internal terrestroid environment. They see and hear Horx, enclosed in his Jovoid cabin, on a communicator screen.

Recently, Horx transported Merseians who made scientific observations. However, Ymirites are unable to differentiate between oxygen-breathing species. We infer that Aycharaych was present and that that was when he read Horx's mind and blackmailed him to attempt the murder of Flandry and Chives.

I should have mentioned in The Dispersal Of Ymir that, apart from planets, Terrans and Ymirites have also traded scientific information about physics at different pressures and about biologies based on different elements. Terran knowledge gained from Ymirites is not classified so the Merseians would not have needed to make the cursory observations alleged by Horx.
