Sosostris is a poor, low-population world with a population of less than 10,000 sophonts.

• This poor world is struggling to establish itself and living conditions in many areas are rudimentary.
• This world is a "Twilight Zone World", a planet that is tidally-locked to its star. It has a hot side that permanently faces the star, a cold side that permanently faces away, and a narrow twilight zone in-between.
• It is a member of the Solomani Confederation in the Sephi Hydra Subsector of Aldebaran Sector.

• It is a member of the Simonides Run.

History & Background (Dossier)

Sosostris is a member of the Simonides Run, a cluster and locally important trade route.

Solomani Security keeps a close eye on things to ensure the security of the Confederation and the well-being of its loyal citizens. Almost anyone could be a SolSec informant, passing on all sorts of useful information: some gain a reward or benefit for their actions, others are coerced, but many see it as an act of duty to help protect the Solomani state and its interests.

World Starport

Sosostris has a Class C Starport, an average quality installation which features 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.

World Technology Level

Sosostris possesses a Technology Level of TL–9.

• Common Communication technologies for this TL include: Fiber optics and satellite communication and data networks.
• Common Power Generation technologies for this TL include: Early fusion power.
• Common Transportation technologies for this TL include:
  • Land: Ultra high-speed trains and early grav vehicles.
  • Water: High efficiency sailcraft, multihulled seacraft, improved artificial gills.
  • Air: Tiltrotorcraft, exotic VTOL's, PARWIG, and rocket-assisted suborbitals.
  • Space: SSTO spacecraft, early military spacecraft (System Craft), and interstellar STL starships
  • FTL: Prototype Jump Drive-1.

World Government

Sosostris is governed by Self-Perpetuating Oligarchy. A single family or small group provides the leadership and important positions in the government. These positions are inherited by member of the group or their family members. The organization may be a monarchy, with titles passed to family members, or a plutocracy where inheritance of the family fortune includes government position. Alternatively, the organization may be a more typical government apparatus, only with positions of power inherited.

World Law Level

Sosostris has a low law level. There are few laws, covering only important areas. There may be few or no law enforcement officers, the expectation is citizens will bring law breakers to the attention of the Judicial system. Legal proceedings will be fast, with few people involved. For interactions outside of the framework of the laws, cultural norms dominate. Portable energy weapons, body pistols, explosives, and poison gas are typically regulated or prohibited.
