Thysh is a pre-agricultural, rich garden world with a moderate population of over a hundred million, but not yet at a billion sophonts in population size.

  • Garden worlds are known for their near-ideal utopian environments conducive to most sophonts, plants, animals, and other forms of life.
  • It is a pre-agricultural world with an environment suitable for large scale agricultural and livestock industries that have not yet been widely developed.
  • This is a rich world with a prosperous and thriving world economy.
  • Its economy and population are growing and living conditions are expected to quickly rise barring outside forces.
  • This is a temperate world, with a climate of pleasant, average temperatures, considered to be an ideal or near-ideal environment by many different sophont species.
  • It is a Non-Aligned world dominated by human sophonts located in the Abidal Subsector of Halcyon Sector.

System Data[edit]

Dugeda-Thysh System[edit]

The primary is Dugeda, an ordinary yellow main sequence star. It has a luminosity of 1.21 Sols, a mass of 1.04 Sols and a diameter of 1.433 million km. Dugeda's inner system consists of (II) an exotic atmosphere stormworld – orbital positions (I) and (III) are empty. (IV) Thysh orbits within the habitable zone and is designated the mainworld. (V) an exotic atmosphere bigworld forms the outer system. All of the worlds retain satellites.

Mossin Subsystem[edit]

The companion is Mossin, a dim dwarf star orbiting Dugeda at 75.3 AU (orbital position (X), 11.3 billion km) with an orbital period of 640 years 267 days. It has a luminosity of 0.0004 Sols, a mass of 0.83 Sols and a diameter of 12,500 km. It retains no planetary bodies.

Plant Subsystem[edit]

The far companion is Plant, a red subdwarf star orbiting Dugeda at 312.9 AU (orbital position (XIII), 46.8 billion km) and has an orbital period of 5480 years. It has a luminosity of 0.0006 Sols, a mass of 0.058 Sols and a diameter of 74,000 km. (I) a vacuum worldlet, and (III) an exotic atmosphere bigworld form the outer system – orbital position (II) is empty. The bigworld retains satellites.

Mainworld Data[edit]

(IV) Thysh[edit]

(IV) Thysh is designated the mainworld. It orbits Dugeda at a mean distance of 1.02 AU, it has an orbital period of 383 days 13 hours and a rotation period of 28.25 hours. The axial tilt is 12 degrees. Thysh has a diameter of 12,554 km, a density of 5.37 g/cm³, and a surface gravity of 0.96 G. The world is geologically active. Its atmosphere is rated as Dense, with a mean surface pressure of 2.15 bar and a composition of 77% nitrogen, 22% oxygen, and 1% argon, carbon dioxide, neon and other trace gases. Approximately 74% of the surface is covered in oceans of liquid water: average tidal ranges are around 0.1m. Mean surface temperature: 17°C. The atmosphere is dynamic and local weather systems, driven by the star and the seas, work their way across the globe. The climate is seasonal.

Mainworld Geography & Topography[edit]

Total surface area: 495 million km², Land surface area: 129 million km², Water surface area: 366 million km².

Native Lifeforms[edit]

Thysh is a garden world and has extensive native life. The local flora is extremely profuse, with a tendency towards broad hollow stems and flat disc-shaped leaves: foliage is generally green in colour. Their metabolic processes power the process of atmospheric renewal. The majority of local fauna follows the body pattern Bilateral HSB-T-NN-LN-T, with bony interiors, ichor fluids, and skin exteriors: many species are gigantic and most have powerful beaks. Most local lifeforms can be digested by humans, though they have an unpleasant, slightly metallic flavour that must be removed by extensive processing or masked with strong spices.

History & Background / Dossier[edit]

Thysh (2513 Halcyon) is a temperate, pleasant, self-sufficient world ruled by a largely benevolent but absolute Overlord. It is a popular vacation destination and there is ongoing demand for novelties, luxury items and high-tech gadgets.

World Starport[edit]

Thysh 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[edit]

Thysh possesses a Technology Level of TL–7.

  • Common Communication technologies for this TL include: Early video and early satellite communication networks.
  • Common Power Generation technologies for this TL include: Early fuel cells, solar energy, and geothermal power sources.
  • Common Transportation technologies for this TL include:
    • Land: Improved automobiles, hovercraft, and bullet trains.
    • Water: Hydrofoils and early triphibians.
    • Air: Hang gliders and supersonic jets.
    • Space: Deep space probes and interplanetary spacecraft (System Craft).

World Government[edit]

Thysh is governed by a Charismatic Dictatorship. Charismatic governments justify their ability to rule by simply asserting their right to rule. Charismatic dictatorships are young governments, coming as a recent change and rely on the leader(s) to supply head of government.
