Jump map from Travellermap.com

Celian is a low population, fluidic hellworld of less than 10,000 sophonts struggling to survive in a inhospitable environment.

• A fluid world has an oceanic geography of a liquid other than water such as ammonia, methane, hydrocarbons, or other exotic liquids.
• Hellworlds often offer daily, and sometimes hourly, life-threatening situations to their inhabitants.
• It is a Non-Aligned world dominated by human sophonts located in the Genesti Subsector of Far Home Sector.

System Data

Varl-Celian System

The primary is Varl, a yellow-white subgiant star. It has a luminosity of 10.9 Sols, a mass of 1.95 Sols and a diameter of 3.59 million km. The inner system consists of (III) a vacuum worldlet, (IV) a trace atmosphere inner world, and (V) a trace atmosphere worldlet – orbital positions (I) and (II) are empty. Orbital position (VI) – the habitable zone of the star – is empty. (VII) Celian, designated the mainworld, forms the outer system. None of the worlds in the system have satellites.

Mainworld Data

(VII) Celian

(VII) Celian is designated the mainworld. It orbits Varl at a mean distance of 5.1 AU (763 million km), within the H+ region of the outer system. It has an orbital period of 8 years 90 days and a rotation period of 36.5 hours. The axial tilt is 15 degrees. Celian has a diameter of 10,238 km, a density of 4.57 g/cm³, and a surface gravity of 0.66 G. Its atmosphere is rated as Exotic, with a mean surface pressure of 3.45 bar and a composition of 97% nitrogen (N₂), 2% methane (CH₄), and 1% argon (Ar), carbon dioxide (CO₂), neon (Ne), hydrogen (H₂) and other trace gases. Approximately 6% of the surface is covered in lakes of liquid methane. Mean surface temperature: -126°C. The climate is rated as Frigid and experiences moderate seasonal changes during the local year. The atmosphere is dynamic and powerful weather systems, driven by the star, sweep across the globe.

Mainworld Geography and Topography

Total surface area: 329 million km², Land surface area: 309 million km², Fluid surface area: 20 million km². The atmosphere of Celian is largely nitrogen; photocatalytic processes in the atmosphere lead to the formation of substances such as acetylene (C₂H₂), ethane (C₂H₆) and propane (C₃H₈) that form into clouds, gaseous and liquid ammonia (NH₃), and nitrogen-rich organic smogs. These substances may fall as precipitation. Temperatures at the poles fall to around -165°C, low enough to allow the formation of liquid methane. Large lakes can be found within craters, hollows and depressions across the polar regions.

Native Lifeforms

World starport

Celian 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

Celian possesses a Technology Level of TL–10 or TL-A in Hexadecimal Notation.

• Common Communication technologies for this TL include: Holovision, Personal Global Communications, and advanced Translators.
• Common Power Generation technologies for this TL include: Increasingly advanced fusion plants and advanced fuel cells.
• Common Transportation technologies for this TL include:
  • Land & Water: Grav belts and maturing gravcraft.
  • Air: Greatly improved hybrid grav-aircraft.
  • Space: Improved interplanetary spacecraft (System Craft).
  • FTL: Jump Drive-1.

World government

Celian 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.
