Note

Pressha is a relatively small hydrogen-helium gas giant with large amounts of hydrocarbons in the middle layers of the atmosphere.
When the Krogan Rebellions ended three millennia ago, the chief of naval operations, a distinguished soldier named Mehrkuri, declared his immediate retirement. He disappeared into what was then uncharted territory. It was only two hundred years ago that his ship was found on the surface of Pressha's largest moon. It had landed gently and been deliberately shut down. Of Admiral Mehrkuri, however, no trace was ever found.


Note

Rayingri is a small, barren terrestrial world. While it possesses a reasonably temperate climate and a number of useful resources, no mining corporation is willing to risk investment. This is because a rogue planetoid, dubbed Vahtz by the initial surveyor team, entered the system approximately ten thousand years ago, and was trapped in a decaying orbit around Rayingri. It is nearing the end of its slow spiral inwards. Earthquakes and cyclonic windstorms are increasingly common on Rayingri.
​Within a few hundred years, the planets will rip each other apart. Some travel consortiums have already announced sponsorship of cruises to observe the spectacle.




Note

Sogelrus is a small terrestrial planet with a thin atmosphere of nitrogen and argon. The frigid surface is mainly composed of water ice, which can be plainly seen in the bottoms of recent craters. The dark coloration of the surface is caused by a carbon and ferrous material, pushed up from the denser core by cryo-volcanic processes.
Note

Antirumgon is a small rock and ice planet, with a trace atmosphere of methane and ethane. The frozen surface is mainly composed of carbon with deposits of calcium.
Antirumgon has been used as a crude anchorage for Terminus pirates for many years. The shells of temporary dwellings blasted by Alliance frigate patrols dot the surface. But always, the pirates return to ground their ships' drive charges, chip out some water ice, and trade slaves and stories.
The deeper layers of Antirumgon's interior are semi-liquid slush, due to the presence of methanol. It is thought that bacterium in the deep core create this natural anti-freeze. Some species of Terminus pirate drill through the ice crust to recover this natural alcohol.


Note

Junthor is a large terrestrial planet with a thick atmosphere of carbon dioxide and chlorine. The surface is mainly composed of aluminum with deposits of nickel.
Surveyors found the ruins of a technical civilization near the equator — evidently the colony of an ancient space-faring race. The ruins had subsided to almost nothing — merely wind hollowed husks of arcologies and other mega-structures. In the center of the ruins was a single column whose inscriptions defied translation for several centuries. When linguists finally managed a translation, the elaborate relief carvings said merely "Walk among these works, and know our greatness.". The crude scratches on the base of the reverse side said "Monsters from the id.".

Note

Gagarin is a medium system with five planets.

It is named after the Soviet cosmonaut Yuri Gagarin. He is best remembered as the first human who orbited the Earth, during the Vostok 1 flight of 1961.
