Jump map from Travellermap.com

Thras is an agricultural, nonindustrial garden world with a near-ideal, utopian environment conducive to most sophonts.

• As an agricultural world, this world is a near-ideal environment for producing quality foodstuffs of plant, animal, and other forms. Quality foodstuffs are a major export commodity for this world.
• It requires extensive imports of outside technology to maintain a modern, star-faring society. Having to import most manufactured and high tech goods drives the price up for these items at this world.
• Its economy and population are growing and living conditions are expected to incrementally rise barring outside forces. The world will grow even quicker when its industrial sector begins to develop.
• It is a Non-Aligned world dominated by human sophonts located in the Natar Subsector of Far Home Sector.

System Data

Okada-Thras System

The primary is Okada, an ordinary yellow-white main sequence star. It has a luminosity of 2.584 Sols, a mass of 1.196 Sols, and a diameter of 1.742 million km. The inner system consists of (II) a trace atmosphere inner world, (III-I) a corrosive atmosphere inferno world, (III-II) a corrosive atmosphere inferno world, and (IV) a vacuum worldlet – orbital position (I) is empty. (V) Thras orbits within the habitable zone and is designated the mainworld. (VI) a very thin atmosphere hospitable world, (VII) a ringed large gas giant, and (VIII) an exotic atmosphere bigworld form the outer system. Many of the worlds retain satellites.

Mainworld Data

(V) Thras

(V) Thras is designated the mainworld. It orbits Okada at a mean distance of 1.72 AU (257.3 million km), within the habitable zone. It has an orbital period of 2 years 23 days and a rotation period of 45 hours. The axial tilt is 14 degrees. Thras has a diameter of 12,466 km, a density of 5.67 g/cm³, and a surface gravity of 0.99 G. The world is geologically active. Its atmosphere is rated as Thin, with a mean surface pressure of 0.72 bar and a composition of 77% nitrogen (N₂), 21% oxygen (O₂), 1% argon (Ar), and 1% water vapor (H₂O), carbon dioxide (CO₂), ozone (O₃), neon (Ne) and other trace gases. Approximately 70% of the surface is covered in oceans of liquid water: average tidal ranges exceed 0.2m. Mean surface temperature: 8°C. The climate is rated as Cold and experiences minor seasonal changes during the local year. The atmosphere is slow and moderate weather systems driven by the star and the oceans work across the globe.

Mainworld Geography and Topography

Total surface area: 488 million km², Water surface area: 342 million km², Land surface area: 146 million km².

Native Lifeforms

Okada-Thras System

Thras, the mainworld, has primitive native life, consisting almost entirely of microscopic cyanobacteria-parallels that exist in most ecological niches. Their metabolic functions maintain the process of atmospheric renewal.

The cold marginally hospitable world lying in orbital position (VI) (within the H+ region of the outer system) has primitive native life, consisting entirely of microscopic cyanobacteria-parallels that exist in any location where they can find even a minimal trace of shelter and warmth. Their metabolic functions maintain the process of atmospheric renewal.

No other world in the system is known to have native life.

History & Background (Dossier)

No information yet available.

World starport

Thras 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.

World technology level

Thras possesses a Technology Level of TL–6.

• Common Communication technologies for this TL include: Telephone, radio, and television.
• Common Power Generation technologies for this TL include: Early fission power generation, advanced water and wind generation of electricity.
• Common Transportation technologies for this TL include:
  • Land: Improved automobiles, early ATV's, and dedicated AFV's.
  • Water: Amphibious vehicles, improved submersibles, and early SCUBA gear.
  • Air: Early jet aircraft and rotorcraft VTOL's.
  • Space: Early unmanned rocket delivery systems and early manned orbital rockets.

World government

Thras 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.
