System Data[edit]

Firag-Exad System[edit]

The primary is Firag, an ordinary yellow main sequence star. It has a luminosity of 0.62 Sols, a mass of 0.917 Sols and a diameter of 1.266 million km. The inner system consists of (I) a vacuum worldlet, and (II) a vacuum worldlet. (III) Paramal, a ringed large gas giant, orbits within the habitable zone: (IIId) Exad is its largest satellite and is designated the mainworld. (IV) a thin atmosphere hospitable world, (V) a small gas giant, and (VI) a small ice giant form the starward part outer system. Orbital positions (VII) through (XIII) are unavailable due to the presence of the companion star. (XIV) a sparse icy planetoid belt forms the spaceward edge of the outer system. All of the gas giants retain families of satellites.

Olarna Subsystem[edit]

The companion is Olarna, a small red main sequence star that orbits Firag at a mean distance of 78.2 AU (orbital position (XII), 11.7 billion km) with an orbital period of 722 years. It has a luminosity of 0.001 Sols, a mass of 0.215 Sols and a diameter of 280,000 km. (I) a vacuum iceworld, (II) a vacuum iceworld, (III) an exotic atmosphere radworld, and (IV) a sparse icy planetoid belt form the outer system. The radworld retains two large satellites.

(III) Paramal[edit]

(III) Paramal is a large gas giant that orbits Firag at a mean distance of 0.65 AU, within the habitable zone, and has an orbital period of 199 days 21 hours. It has a diameter of 76,000km and is a pale reddish-brown colour. It retains a family of five major satellites of which the fourth, (IIId) Exad, is designated the mainworld. A group of three large storms, lying to the north of the enormous world's equator, have been circling for centuries.

Mainworld Data[edit]

(IIId) Exad[edit]

(IIId) Exad is the fourth of the five major moons of Paramal and is designated the mainworld. Exad orbits its parent world at a mean distance of 40 diameters (3.04 million km), with an orbital period of 68 days 18 hours and a rotation period of 45.5 hours. The axial tilt is 11 degrees. It has a diameter 10684 km, a density of 5.13 g/cm³, and a surface gravity of 0.78 G. The world is geologically very active. Its atmosphere is rated as Standard, Tainted, with a mean surface pressure of 0.94 bar and a composition of 71% nitrogen (N2), 28% oxygen (O2), and 1% argon (Ar), water vapor (H2O), carbon dioxide (CO2), neon (Ne) and other trace gases. The taint is caused by the high percentage of atmospheric oxygen and by relatively high levels of background radiation: emission rates exceed 1 rad per hour. Approximately 58% of the surface is covered in oceans of liquid water: average tidal ranges exceed 0.4m. Mean surface temperature: 17°C. The atmosphere is dynamic and powerful weather systems, driven by the star and the oceans, sweep across the globe. The climate is seasonal.

Mainworld Geography and Topography[edit]

Total surface area: 359 million km², Water surface area: 208 million km², Land surface area: 151 million km².

Native Lifeforms[edit]

Exad, the mainworld, has extensive, abundant native life, with complex organisms inhabiting every ecological niche. Their metabolic functions drive the process of atmospheric renewal. Vast amounts of flora swathe the continents and produce huge amount of oxygen. The world has a complex ecosystem, with many types of gigantic fauna.

The cold marginally hospitable world lying in orbital position (IV) (within the H+ region of the outer system) has extensive native life, consisting of minute multicellular organisms that can be found in most ecological niches. Their metabolic functions drive the process of atmospheric renewal.

History & Background (Dossier)[edit]

World starport[edit]

Exad 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]

Exad possesses a Technology Level of TL–4.

  • Common Communication technologies for this TL include: Telephone and telegraphs, widespread printing.
  • Common Power Generation technologies for this TL include: Early electricity, hydrocarbon internal combustion.
  • Common Transportation technologies for this TL include:
    • Land: Trains and early automobiles.
    • Water: Clippers and steam ships.
    • Air: Dirigibles, balloons, very basic rockets.

World government[edit]

Exad has a Civil Service Bureaucracy government.

  • It is a government by agencies employing individuals selected for their expertise.
  • The typical power source of this government is an Oligarchy.
  • The typical power structure of this government is a Unitary State.

World military[edit]

The locally raised army is equipped with TL–4 weapon systems and has 1,000 battalions organized into 50 divisions in 10 army corps divided into two field armies. One controls the northern and the other protects the southern hemispheres. Local megafauna are incorporated into transport, logistics and cavalry units. Native trained large animal vets are part of the standard TOE. These troops also function in security roles, law enforcement, and civil affairs. Each regiment is designed to function independently and usually has its own fortifications co-located with each settlement.

There are 100 elite battalions trained with embedded military advisers from off world at Vey (world). This corp has five divisions. They are equipped and trained with imported TL–8 equipment manufactured off world at Vey (world). The The Last Line has arranged the military contracts necessary for this force. They see this as an emergency contingency plan in case a garrison was needed off world and more advanced front line units were needed elsewhere. Transport would need to be contracted with civilian corporate or mercenary providers. A small battalion can be carried by the Vey Class Troop Transports of the fleet. The central government uses these forces as security, an elite ready reserve and deterrent force.
