Chang-Su is a poor, non-agricultural, high-population desert world, with a billion or more sophonts struggling to survive in a inhospitable environment.

• This world has no free-standing water.
• It is unable to produce quality foodstuffs and must import them.
• Despite this world's industrial prowess, the world remains poor. Some blame it on the high prices of food, which must be imported. Others blame the nature of a desert world. Whatever the reason, something needs to change in order for this world to prosper.
• It is a Non-Aligned world dominated by human sophonts located in the Banderhue Subsector of Theta Borealis Sector.

• This is a hot world, with a climate of high temperatures.

Description (Astrography & Planetology)

The worlds of the system have been surveyed. They consist of:

• The mainworld.
• x7 secondary rocky worlds.
• x1 planetoid belt.

Mainworld Data

The mainworld orbits within the star's Habitable Zone.

• It lies within the zones warmer inner H+ region
• It receives higher levels of stellar energy.

• The world orbits inside the stars Jump Shadow.

Mainworld Size (S)

Chang-Su is a Meso World between 5,600km and 7,200km in diameter. The world has low gravity between 0.32G and 0.46G. The horizon will appear about 3.6km away.

Mainworld Atmosphere (A)

Chang-Su has a pressure of 0.10 to 0.42 atmospheres. The very thin pressures require a respirator or Oxygen Mask. TL–5 or more advanced survival gear is required to settle this world.

Mainworld Hydrosphere (H)

Chang-Su has no free-standing water or ice on the surface. Wilderness refueling isn't possible on this world. Water for the inhabitants needs to be imported and extensively recycled. These worlds are classified Desert World or a Hell World depending on their atmosphere.

History & Background (Dossier)

Chang-Su's society descends from the same Solomani root as that of Chang-Tu, Manshu and Shen Tsi across the sector border in Theron. Indeed, those worlds were first settled from here. Unlike its rather xenophobic offshoots, Chang-Su is welcoming to outsiders, cultivating warm relations with other worlds. This is necessary, given the limited ability of this desolate world to support its high population without outside trade and supply.

Chang-Su has a Class C Starport, an average quality installation which includes amenities including unrefined fuel for starships, some brokerage services for passengers and cargo, and a variety of ship provisions. There is a shipyard capable of doing maintenance and other kinds of repair. Ports of this classification generally have only a downport, unless this is a trade port or system with an hostile environment mainworld.
