Rosamin is an agricultural, nonindustrial, and very rich garden world with a near-ideal, utopian environment conducive to most sophonts.

System Data[edit]

Palidor-Rosamin System[edit]

The primary is Palidor, an ordinary yellow main sequence star. It has a luminosity of 0.886 Sols, a mass of 0.98 Sols, and a diameter of 1.391 million km. The inner system consists of (II-I) a trace atmosphere worldlet, and (II-II) an exotic atmosphere stormworld – orbital position (I) is empty. (III) Rosamin orbits within the habitable zone and is designated the mainworld. (IV) a very thin atmosphere hospitable world, (V) a small gas giant, (VI) a sparse stony planetoid belt, (VII-I) a large gas giant, (VII-II) a ringed large gas giant, and (VIII) a small ice giant form the outer system. Many of the worlds retain satellites.

Mainworld Data[edit]

(III) Rosamin[edit]

(III) Rosamin is designated the mainworld. It orbits Palidor at a mean distance of 0.83 AU (124.2 million km), within the habitable zone. It has an orbital period of 279 days 0 hours and a rotation period of 21 hours. The axial tilt is 22 degrees. Rosamin has a diameter of 12,775 km, a density of 5.62 g/cm³, and a surface gravity of 1.02 G. The world is geologically active. Its atmosphere is rated as Dense, with a mean surface pressure of 1.62 bar and a composition of 80% nitrogen (N2), 19% oxygen (O2), and 1% argon (Ar), water vapor (H2O), carbon dioxide (CO2), ozone (O3), neon (Ne) and other trace gases. Approximately 73% of the surface is covered in oceans of liquid water: average tidal ranges exceed 0.3m. Mean surface temperature: 19°C. The climate is rated as Temperate-Prime and experiences moderate seasonal changes during the local year. The atmosphere is active and moderate weather systems driven by the star and the oceans sweep across the globe.


Rosamin retains two natural satellites, a tiny vacuum worldlet named Marad and a very thin atmosphere hospitable world named Cherish:

(IIIa) Marad (UWP YS00000-0, orbiting at 6 Diameters/75,000 km)
(IIIb) Cherish (UWP Y323000-0, orbiting at 30 Diameters/385,000 km)

Mainworld Geography and Topography[edit]

Total surface area: 513 million km², Water surface area: 374 million km², Land surface area: 139 million km². Two large continents (Seemu and Solu, dominating the southern hemisphere), and various subcontinental landmasses, large islands and chains of archipelagos.

Native Lifeforms[edit]

Palidor-Rosamin System[edit]

Rosamin, the mainworld, has extensive, abundant native life, with complex organisms inhabiting every ecological niche. Flora is abundant: foliage is generally long and conical and is primarily green in color. Their metabolic functions drive the process of atmospheric renewal. Fauna follows a wide variety of body patterns but the prevalent form is Bilateral HS-TB-LN-LL-N, with cartilage interiors, ichor fluids and leathery exteriors. Most native organisms have a bland flavor and a gritty texture and can be digested by humans after basic processing (cooking).

  • Cherish, Rosamin's temperate marginally hospitable moon 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 (IV) (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)[edit]

A pleasant garden world with a rich and complex ecology.

World starport[edit]

Rosamin 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]

Rosamin possesses a Technology Level of TL–4.

All of the nations on Rosamin enforce the technological ceiling. Possession of advanced technology without appropriate licenses and permits carries legal penalties.

World Government[edit]

Rosamin 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. Four major nation-states, consisting of two representative democracies (Calornia and Lisand), a self-perpetuating oligarchy (the Kingdom of Zumin) and a civil service bureaucracy (the Republic of Ansibar). Each nation is centered on a large island and lays claim to extensive maritime territories. The nations are economic rivals and seek to outdo one another in terms of standards of living, quality of infrastructure and architectural beauty, but cooperate closely on matters such as defense and the ecology.

World Military[edit]

Approximately 250,000 personnel in total. Each nation-state on Rosamin maintains its own professional standing army and maritime navy. Forces are generally equipped to TL 4 standards, with extremely good training. All of the nations on Rosamin contribute personnel to the Rosamin Significant Threat Brigade, an elite force trained on Dhon and equipped to TL 9 standards (including armored grav vehicles).

World Economy[edit]

  • Resources: D (Very abundant)
  • Labor: 8 (Hundreds of millions)
  • Infrastructure: D (Comprehensive)
  • Efficiency: +4 (Advanced)

Trade Data[edit]

Agriproduce, processed foodstuffs, manufactured goods, unique items, low tech items. Trading in advanced technology is illegal and carries penalties including confiscation of goods, fines and imprisonment: despite that, there is great demand for items such as 3V entertainment systems and similar luxuries.

World Demographics[edit]

Population 6,840,000

  • Humaniti (Human races)
    • Solomani (Major Race): 6.57 million (96% of the population), descended from colonists from Dhon. They refer to themselves as Terrans.
  • Native Non-Human Races:
    • Hoppers: 270,000 (4% of the population), concentrated within hives in human communities.


The major cities are Pell, Londim, Partos and Esk, each located on large subtropical islands lying in the northern hemisphere. They are surrounded by scattered agricultural and fishing communities.

World Culture[edit]

  • Homogeneity: C (Fragmented)
  • Acceptance: D (Very Xenophilic)
  • Strangeness: 8 (Very confusing)
  • Symbols: D (Very abstract)
