Tsushima is a low-population fluid world with a population of less than 10,000 sophonts.

• A fluid world has an oceanic geography consisting of heavily contaminated water or a substance such as ammonia, methane, hydrocarbons, or other exotic liquid.
• It is a member of the Solomani Confederation in the Nyssa Subsector of Canopus Sector.

Description (Astrography & Planetology)

Stellar Data

• It is a turbulent yellow subgiant.

Tsushima has a solitary primary star.

	Remarks		Unstable pulsating star. It produces high levels of EM noise.

System Data

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

• The mainworld.
• x12 secondary rocky worlds.
• x4 gas giants.

Mainworld Data

Tsushima orbits towards the inner edge of its star's habitable zone.

Mainworld Size (S)

Tsushima 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)

Tsushima has an Exotic Atmosphere and possesses an unusual gas mix which requires the use of oxygen tanks. Additionally, protective suits, while not necessary, are recommended. TL–8 or more advanced survival gear is required to settle this world.

• It experiences high temperatures.
• Greenhouse gases in the atmosphere push up the world's surface temperatures.

Mainworld Hydrosphere (H)

Tsushima has 65-75% of its surface covered by liquid water or ice heavily tainted with other substances, which makes it dangerous, corrosive, or toxic. Wilderness refueling will be difficult. Water for the inhabitants needs to be imported and extensively recycled. These worlds may be Hell Worlds.

• The water on the surface may be unsuitable for use or consumption without extensive filtering and purification.
• Refining for fuel may cause issues with shipboard purification plants.
• Toxic smogs, fogs, and steams rise from the warm waters.

Mainworld Geography and Topography

No centrally held map of the world exists within AAB Library Data records.

(Blank map, exotic world.)

History & Background (Dossier)

Tsushima has a population with its origins in the Japanese archipelago, lying just to the east of the Eurasian continent on Terra.

The system's giant primary star causes interference, strange tones and noises, and heavy static on commo and sensors.

Solomani Security keeps a close eye on things to ensure the security of the State 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 (St)

Tsushima has a Class E Starport, a frontier quality installation with few expected amenities. There is unrefined fuel for starships and a limited variety of ship provisions. There is no shipyard of any kind, but there may be parts and technical support for doing minor services and repair. Ports of this classification generally consist of a downport.

World Population (P)

Tsushima has population of 600 sophonts (hundreds).

• This is a Low Population World and the population would be too low to sustain itself without moderate outside assistance. This may represent a large transient population such as the crew of a fleet of starships, the dwindling remnants of a dying colony, a construction team building a new colony, or an outpost that could evolve into a colony.
• The population almost entirely consists of Solomani humans.

Linguistic Topography

The most commonly heard languages are:

• Nihongo, a Terran language occasionally heard within the Solomani Confederation. It is the principal dialect of the language known in Anglic as Japanese.
• Rim Anglic, a dialect of Anglic and the principal language of the Confederation.

World Technology Level (T)

Tsushima 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 (G)

Tsushima has no central government or substantial government apparatus; an Anarchy. The largest governmental structure would be a family, tribe, or single clan. The largest group will be between 50 and 100 individuals, and there may be dozens to hundreds of them. This governmental structure can be stable over long periods of time if the population remains small or geographically separated.

World Law (L)

Tsushima has no law in practice. It is an Anarchy. On many worlds, this by itself justifies an Amber Zone advisory. 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.
