Lon Marin is a pre-agricultural and nonindustrial garden world.

  • 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.
  • 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 slowly rise barring outside forces.
  • It is a member of the High Senate in the Loran Subsector of Halcyon Sector, which is part of the Distant Fringe.

System Data[edit]

Tharsen-Lon Marin System[edit]

The primary is Tharsen, an ordinary yellow-white main sequence star. It has a luminosity of 2.126 Sols, a mass of 1.144 Sols, and a diameter of 1.639 million km. The inner zone consists of (I) a vacuum worldlet, (II) a trace atmosphere inner world, and (III) a corrosive atmosphere inferno world. (IV) Lon Marin orbits within the habitable zone and is designated the mainworld. (V) a dense atmosphere bigworld, (VI) a large gas giant, and (VII) a ringed large gas giant form the outer system. Most of the worlds retain satellites.

Olaf Subsystem[edit]

The companion is Olaf, an ordinary red subdwarf star that orbits Tharsen at 621 AU (orbital position (XIV), 93 billion km) and has an orbital period of 14,450 years. It has a luminosity of 0.0038 Sols, a mass of 0.114 Sols, and a diameter of 167,000 km. (I) a trace atmosphere iceworld, (II) an exotic atmosphere bigworld, and (III) a small gas giant form the outer system. The two outer worlds retain satellites.

Mainworld Data[edit]

(IV) Lon Marin[edit]

(IV) Lon Marin is designated the mainworld. It orbits Tharsen at a mean distance of 1.08 AU (161.6 million km), within the habitable zone. It has an orbital period of 1 year 108 days and a rotation period of 32.5 hours. The axial tilt is 17 degrees. Lon Marin has a diameter 9,516 km, a density of 5.77 g/cm³, and a surface gravity of 0.78 G. The world is geologically active. Its atmosphere is rated as Dense, with a mean surface pressure of 1.87 bar and a composition of 78% nitrogen (N2), 21% oxygen (O2), and 1% argon (Ar), water vapor (H2O), carbon dioxide (CO2), neon (Ne) and other trace gases. Approximately 73% of the surface is covered in seas of liquid water: average tidal ranges exceed 0.5m. Mean surface temperature: 26°C. The atmosphere is dynamic and strong weather systems driven by the star and the seas scour the surface. The climate is seasonal.

Satellite[edit]

Lon Marin retains a single natural satellite, a cratered trace atmosphere worldlet named Tessen:

(IVa) Tessen (UWP G310265-8, orbiting Lon Marin at 14 Diameters/133,000 km)

Mainworld Geography and Topography[edit]

Total surface area: 284 million km², Water surface area: 207 million km², Land surface area: 77 million km².

Native Lifeforms[edit]

Lon Marin, the mainworld, has extensive, abundant native life, with complex organisms inhabiting every ecological niche. Their metabolic functions drive the process of atmospheric renewal.

World starport[edit]

Lon Marin has a Class B Starport, a good quality installation which includes all the expected amenities including refined fuel for starships, brokerage services for passengers and cargo, and a variety of ship provisions. There is a shipyard capable of doing annual maintenance, overhauls and most kinds of repair, and construction of non-starships. Most ports of this classification have both a Highport and a Downport.

World technology level[edit]

Lon Marin 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 gears.
    • 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[edit]

Lon Marin 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 monarchy, with titles passed to family members. Or a plutocracy where inheritance of the family fortune includes government position. Or the organization may be more typical organization with positions of power inherited.
