Zuramid is a nonindustrial water world, which has 90% or more of its surface covered in an ocean of water.

  • The inhabitants of this world live on the roughly 10% of exposed land mass, in underwater colonies, on city ships, or similar arrangements.
  • As a nonindustrial world, it requires extensive imports of outside technology to maintain a modern, star-faring society. The need to import most manufactured and high technology goods drives the price of these goods up in the open market.
  • It is a member of the Rimward Federation in the Demon's Eye Subsector of Far Home Sector, which is part of the Distant Fringe.

System Data

Almera-Zuramid System

The primary is Almera, 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 trace atmosphere inner world, (III) a corrosive atmosphere inferno world, and (IV) Zuramid, designated the mainworld – orbital position (II) is empty. (V) A ringed large gas giant orbits within the habitable zone. The outer worlds retain satellites.

Purdur Subsystem

The companion is Purdur, a dim red subdwarf star that orbits Almera at a mean distance of 41.7 AU (orbital position (X), 6.3 billion km) and has an orbital period of 236 years 64 days. It has a luminosity of 0.00103 Sols, a mass of 0.081 Sols, and a diameter of 109,000 km. (I) a vacuum iceworld, (II) a vacuum worldlet, and (III) a small gas giant form the outer system. Many of the worlds retain satellites.

Mainworld Data

(IV) Zuramid

(IV) Zuramid is designated the mainworld. It orbits Almera at a mean distance of 1.04 AU (155.6 million km), within the H– region of the inner system. It has an orbital period of 339 days 19 hours and a rotation period of 17.5 hours. The axial tilt is 25 degrees. Zuramid has a diameter of 13,244 km, a density of 6.16 g/cm³, and a surface gravity of 1.16 G. Tidal stresses generated by the gravitational pull of Darnation, its large moon, cause frequent geological activity. Its atmosphere is rated as Dense, Tainted, with a mean surface pressure of 3.38 bar and a composition of 79% nitrogen (N2), 20% oxygen (O2), and 1% argon (Ar), water vapor (H2O), carbon dioxide (CO2), neon (Ne) and other trace gases. The taint is caused by the extremely high atmospheric pressure: breathing the air without artificial assistance can result in nitrogen narcosis and oxygen toxicity. Zuramid is a water world: approximately 99.7% of the surface is covered in oceans of liquid water. Average tidal ranges exceed 0.75m. Mean surface temperature: 4°C. The climate is rated as Temperate-Cool and experiences moderate changes during the local year. The atmosphere is dynamic and powerful weather systems driven by the star and the oceans surge across the globe.


Zuramid retains a single natural satellite, a hot very thin atmosphere hospitable world called Darnation:

(IVa) Darnation (UWP H520000-0, orbiting at 25 Diameters/320,000 km)

Geography and Topography

Total surface area: 551 million km², Water surface area: 549.5 million km², Land surface area: 1.5 million km². Almost the entire surface is covered by the Zuram, the world-ocean. Close to the equator the waters are shallower, and chains of volcanic islands dot the seas. Occasional isolated peaks occur within the tropics, but there is almost no land between the tropics and the poles. Both the northern and southern poles have extensive permanent ice caps, which shrink and expand seasonally.

Native Lifeforms

Zuramid, the mainworld, lying within the H– region of the inner system, has extensive, abundant native life, with complex organisms inhabiting every ecological niche. Their metabolic functions drive the process of atmospheric renewal.

History & Background (Dossier)

No information yet available.

World starport

Zuramid 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

Zuramid possesses a Technology Level of TL–6.

World government

Zuramid is governed by a Representative Democracy where government leadership is representatives elected by eligible voters. What determines an eligible voter varies. The representatives determine policy, including selecting members of the bureaucracy. There can be referendum, votes by eligible voters on specific subjects.

Executive power is exercised by the leadership of an elected political party. Legislative power is vested in both the ruling party and the parliament of which it is a part. The judiciary is independent of the executive and the legislature.

World military

Approximately 800 full-time professional personnel, supported by a large volunteer militia drawn from the citizens of the world as necessary.

World economy

  • Resources: B (Abundant, both biological and mineral)
  • Labor: 4 (Tens of thousands)
  • Infrastructure: 0 (Non-existent, individual compounds have their own services)
  • Efficiency: +0 (Typical)

Trade Data

  • Primary Commodities: marine produce of all kinds, pharmaceutical products derived from marine organisms.
  • Secondary Commodities: mineral ores, preserved foodstuffs, trinkets (seashells, carved bones).
  • Demand: advanced equipment and tools, luxuries.

World demographics

Population 783,000

World culture

  • Homogeneity: 7 (Discordant, strongly differing political views)
  • Acceptance: 3 (Xenophobic, dislike of outsiders)
  • Strangeness: 5 (focused on the ocean and the weather, unique local architecture)
  • Symbols: 6 (weather telltales, totems, good luck charms, boundary markers)
