Mainworld Data[edit]

Tarras is tidally locked to the system's two stars.[2]

  • The stars are always high in the sky on the bright face, they hang on horizon in the twilight zone, while the cold dark face is in permanent darkness.
  • The world experiences libration - a regular wobble - as it orbits, causing the stars to move in the sky.

Mainworld Size (S)[edit]

Tarras is a Small World between 4,000km and 5,600km in diameter. The world has low gravity between 0.24G and 0.34G. The horizon will appear about 3km away.

Mainworld Atmosphere (A)[edit]

Tarras has a pressure of less than 0.1 atmospheres which requires the use of a Vacc Suit. TL–8 or more advanced survival gear is required to settle this world.

Mainworld Hydrosphere (H)[edit]

Tarras 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.

Mainworld Geography and Topography[edit]

History & Background (Dossier)[edit]

Comp-Prog-Dav-R-Deitrick-Starter-Trav-Page-16 16-July-2018a.jpg

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 (St)[edit]

Tarras 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 Population (P)[edit]

Tarras has a population of 2,000 sophonts (thousands).

  • This is a Low Population World and the population would be too low to sustain itself without a little outside assistance. This may represent the home base of a sizable but mostly transient population such as the base of a major starship expedition, the last generation of a dying colony, the first generation of a new colony, or a large outpost that will probably evolve into a colony if not stopped.
  • The population almost entirely consists of Solomani humans.

Linguistic Topography[edit]

The most commonly heard languages are:

World Technology Level (T)[edit]

Tarras possesses a Technology Level of TL–11 or TL-B in Hexadecimal Notation.

World Government (G)[edit]

Tarras is governed by a Feudal Technocracy. Society divides itself based on the technical requirements of the society. Each of these functions are granted as a fief to an individual or group. Leadership of these fiefs determines the head of the government.

World Law (L)[edit]

Tarras has a moderate level with laws covering many areas of government and interaction. These laws are simple enough that most people can act as their own advocate, though for serious issues a professional is recommended. Law enforcement officials will be present, but not in great numbers. Personal concealable firearms, and anything more destructive, are typically regulated or prohibited.
