Undina is a low-population oceanic water world with a population of less than 10,000 sophonts.

  • It is covered with very deep oceans with less than 1% of its land above sea level.
  • The inhabitants of this world live on the roughly 1% of exposed land mass, in underwater colonies, on city ships, or similar arrangements.
  • It is a Non-Aligned world dominated by human sophonts located in the Irikusk Subsector of Far Home Sector.

System Data[edit]

Mallon-Undina System[edit]

The primary is Mallon, an ordinary white main sequence star. It has a luminosity of 3.5 Sols, a mass of 1.3 Sols, and a diameter of 1.948 million km. The inner system consists of (I) a vacuum worldlet, (III) a thin atmosphere inner world, and (IV) a corrosive atmosphere inferno world – orbital position (II) is empty. (V) Undina orbits within the habitable zone and is designated the mainworld. (VI) a dense stony planetoid belt, (VII) a small gas giant, (VIII) a ringed large gas giant, (IX) an exotic atmosphere bigworld, and (X) a large gas giant form the outer system. Many of the worlds retain satellites.

Mainworld Data[edit]

(V) Undina[edit]

(V) Undina is designated the mainworld. It orbits Mallon at a mean distance of 1.45 AU (216.9 million km), within the habitable zone. It has an orbital period of 1 year 194 hours and a rotation period of 22.5 hours. The axial tilt is 19 degrees. Undina has a diameter of 16,163 km, a density of 5.92 g/cm³, and a surface gravity of 1.36 G. Tidal stresses generated by the gravitational pull of Platitude, its large close moon, cause constant geological activity. Its atmosphere is rated as Dense, Tainted, with a mean surface pressure of 2.12 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. The taint is caused by trace amounts of sulfur dioxide (SO2) and sulfur compounds of volcanic origin. Approximately 99.8% of the surface is covered in oceans of liquid water: average tidal ranges exceed 1.5m. Mean surface temperature: 8°C. The climate is rated as Temperate-Cool and experiences moderate seasonal changes during the local year. The atmosphere is dynamic and violent weather systems driven by the star and the oceans drive across the globe.

Satellite[edit]

Undina retains a single natural satellite, a corrosive atmosphere inferno world named Platitude:

(Va) Platitude (UWP Y6B0000-0, orbiting Undina at 15 Diameters/242,000 km)

Mainworld Geography and Topography[edit]

Total surface area: 821 million km², Water surface area: 817 million km², Land surface area: 4 million km².

Native Lifeforms[edit]

Mallon-Undina System[edit]

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

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

World starport[edit]

Undina has a poor quality starport.

  • A Class D Starport Facility has minimal if any shipyards and can only perform extremely limited repair work.
  • This facility has many skilled personnel who can perform minor repair work.
  • This facility has refueling infrastructure and limited refining capabilities. One may purchase unrefined fuel here.
  • Starports of this class very rarely have both a Lowport and a Highport.

World technology level[edit]

Undina 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).
