Merant is a high-population, pre-rich garden world with a billion or more sophonts in population size, a near-ideal utopian environment conducive to most sophonts, and still lacks adequate population to expand its economy to a rich status.

Astrography and Planetology[edit]

This star system is detailed using the Fringian Variant System Description.

  • The Merant system is a part of the Pel Avena Cluster.
  • The supergiant primary star of the Demon's Eye system and the huge Demon's Eye Nebula that surrounds it, lying around 7 parsecs to coreward-trailing, are clearly visible in the sky.

System Data[edit]

Serene-Merant System[edit]

The primary is Serene, an ordinary orange main sequence star. It has a luminosity of 0.352 Sols, a mass of 0.774 Sols and a diameter of 1.168 million km. The inner system consists of (I) a vacuum worldlet, and (II) a thin atmosphere hospitable world. (III) Merant orbits within the habitable zone and is designated the mainworld. (IV) a trace atmosphere worldlet, (V) a small gas giant, (VI) a small ice giant, (VII) a trace atmosphere iceworld, (VIII) an exotic atmosphere bigworld, and (IX) a vacuum worldlet form the outer system. Many of the worlds retain satellites.

(III) Merant[edit]

(III) Merant is designated the mainworld and orbits Serene at a mean distance of 0.64 AU (95.7 million km), within the habitable zone. It has an orbital period of 212 days 14 hours and a rotation period of 47.5 hours. The axial tilt is 17 degrees. Merant has a diameter of 11,777 km, a density of 6.16 g/cm³, and a surface gravity of 1.03 G. The world is geologically active. Its atmosphere is rated as Standard, with a mean surface pressure of 1.01 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 63% of the surface is covered in oceans of liquid water: average tidal ranges exceed 0.5m. Mean surface temperature: 15°C. The climate is rated as Temperate-Prime and experiences moderate seasonal changes during the local year. The atmosphere is dynamic and weather systems, driven by the star and the oceans, drive across the globe.


Merant retains two natural satellites, a vacuum worldlet named Innet and an ice-capped vacuum worldlet named Outree:

(IIIa) Innet (UWP Y200000-0, orbiting at 40 Diameters/470,000 km).
(IIIb) Outree (UWP G301000-0, orbiting at 55 Diameters/650,000 km).

Mainworld Geography and Topography[edit]

Total surface area: 436 million km², Land surface area: 166 million km², Water surface area: 270 million km². There are three major continents (temperate Orneida, mountainous Perserence and rugged Chomleigh), three minor continents (named Asto, Pent and Vestin) and numerous subcontinental landmasses, islands and archipelagos. The major bodies of water are the Arachnid Ocean, the Ocean of Wrecks, the Angel Sea and the Sea of Ice. Both poles are covered with large icecaps.

Native Lifeforms[edit]

Serene-Merant System[edit]

The hot marginally hospitable world lying in orbital position (II) (within the H– region of the inner 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 moisture. Their metabolic functions maintain the process of atmospheric renewal.

Merant, the mainworld, orbits within the habitable zone. It is classified as a garden world: it has abundant and extensive native life that fills every available ecological niche. Their metabolic functions power the process of atmospheric renewal. The local flora has a tendency towards broad tall stems and long narrow leaves: foliage is generally dark green in colour. The majority of local fauna follows the body pattern Radial N-TSB-AL-LL-N, with exoskeletons and scum fluids. There are relatively few species of large land creatures but a huge variety of types massing less than a few kilograms. Most local lifeforms can be digested by humans with few problems but have a deeply unpleasant taste, generally inducing gagging and nausea.

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

History & Background (Dossier)[edit]

No information yet available.

World starport[edit]

Merant has a Class D Starport, a poor quality installation which has few of the expected amenities. There is unrefined fuel for starships and a limited variety of ship provisions. There is no shipyard of any kind, but there may be parts and technical support for doing minor services and repair. Ports of this classification generally consist of only a downport, unless this is a trade port or system with an hostile environment mainworld.

World technology level[edit]

Merant possesses a Technology Level of TL–5.

World government[edit]

Merant has a Balkanized Government. There is no central world government. The world has several governments competing for control of the world. These may be allies, cooperating, competitors, or at war with each other.
