Note

Porolan is an enormous terrestrial planet, half again the size of Earth. Despite its thick atmosphere, the weak output of the red dwarf Macedon leaves its surface biting cold. The crust is mainly composed of silica, but significant deposits of iron and other industrial metals are present. These lodes may prove rich enough to be profitably mined despite the heavy gravity.

Note

Patavig is the second of the Macedon system's giant terrestrial planets, and by far the more interesting. Most of the surface is covered by a vast sea of liquid ammonia, in which a unique aquatic ammonia-based biosphere has developed. While the frozen continents are largely bereft of life, a rich bounty of complex organisms — many larger than a human — flourish in the chilly, toxic seas.
While dreadfully inhospitable to humans, Patavig is suitable for colonization with environmentally-sealed facilities. Initial sites and projects have made good progress.



Note

Fargeluse is a standard hydrogen-helium gas giant with an abundance of airborne hydrocarbons.
Note

WARNING:  Level 1 Pressure Hazard
Sharjila has a very dense atmosphere of ammonia and oxygen. Its temperate surface is mainly composed of alumina with deposits of sulfur. Comm buoys in the system have recently logged a number of unregistered vessels operating nearby.

Sharjila has an extensive silicon-based, oxygen-breathing ecology. Heavily populated areas are covered with fine silica (silicon dioxide) dust, the respiratory by-product of the world's higher animal forms. High-speed surface winds, often laden with abrasive silica dust, present a hazard. In areas where the wind deposits a great deal of silica, footing can be treacherous. EVAs (Extra-Vehicular Activities) discouraged.

Note

Macedon is a medium system with four planets and an asteroid belt. It is probably named for the ancient Greek kingdom of Macedon.
