Mainworld Data

Herios is a satellite of a gas giant.

The mainworld and its gas giant primary orbit within the outer system.

• They receive very low levels of stellar energy.

Mainworld Size (S)

Herios is a Small World between 4,000km and 5,600km in diameter. The world has low gravity between 0.24G and 0.34G. The horizon will appear about 3km away.

Mainworld Atmosphere (A)

Herios has a pressure of less than 0.1 atmospheres which requires the use of a Vacc Suit. TL–8 or more advanced survival gear is required to settle this world.

Mainworld Hydrosphere (H)

Herios has 25-35% of its surface covered by ice, either in vast sheets or contained deep within craters or fractures on the surface. Wilderness refueling is possible. Water for the inhabitants can be acquired by mining and melting ice.

• The surface of the world is composed of a crust of ice many kilometers thick.
• Much of the surface is cratered and covered in thick layers of regolith and dust of meteoric origin, leaving only a small amount of the icy outer shell exposed.
• Below the outer icy shell there may be a world-ocean of liquid water.

Mainworld Geography and Topography

No centrally held map of the world exists within AAB Library Data records.

• Locally, detailed maps may be available.

History & Background (Dossier)

World Starport (St)

Herios has a Class C Starport, an average quality installation which features 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 Population (P)

Herios has a population of 10,000 sophonts (tens of thousands).

• This is a Nonindustrial World, too small to support the complete chain of production of most goods from start to finish.

World Technology Level (T)

Herios possesses a Technology Level of TL–9.

• Common Communication technologies for this TL include: Fiber optics and satellite communication and data networks.
• Common Power Generation technologies for this TL include: Early fusion power.
• Common Transportation technologies for this TL include:
  • Land: Ultra high-speed trains and early grav vehicles.
  • Water: High efficiency sailcraft, multihulled seacraft, improved artificial gills.
  • Air: Tiltrotorcraft, exotic VTOL's, PARWIG, and rocket-assisted suborbitals.
  • Space: SSTO spacecraft, early military spacecraft (System Craft), and interstellar STL starships
  • FTL: Prototype Jump Drive-1.

World Government (G)

Herios 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.

World Law (L)

Herios has a moderate level with laws covering many areas of government and interaction. These laws are simple enough that most people can act as their own advocate, though for serious issues a professional is recommended. Law enforcement officials will be present, but not in great numbers. Personal concealable firearms, and anything more destructive, are typically regulated or prohibited.
