Mainline is a preindustrial world.

• As a preindustrial world, this planet cannot yet manufacture enough high-technology resources to support a modern, star-faring society. Having to import most manufactured and high tech goods drives the price up for these items at this world.
• This world hopes to one day be one of the subsector's industrial powerhouses, but hasn't yet realized that dream. The leaders of this world are regularly embarking on trade missions to attract more investment capital, worker-immigrants, and other necessary stepping stones to achieve this goal.
• It is a Non-Aligned world dominated by human sophonts located in the Darvis Subsector of Hinterworlds Sector.

• This is a "Puzzle" world designated as an Amber Zone. Caution is advised since the world has an environment, laws, customs, life forms, or other conditions that are not well understood and might be a danger to a visitor.
• This world-system has a Military Base, usually associated with military ground forces, which may be located on or off-world.
• This world has a colony at Varag.

History and Background

World Starport

Mainline has a Class B Starport, a good quality installation which includes all the expected amenities including refined fuel for starships, brokerage services for passengers and cargo, and a variety of ship provisions. There is a shipyard capable of doing annual maintenance, overhauls and most kinds of repair, and construction of non-starships. Most ports of this classification have both a Highport and a Downport.

World Population (P)

Mainline has a population of 80,000,000 sophonts (tens of millions).

World Technology Level

Mainline 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

Mainline is governed by a Charismatic Dictatorship. Charismatic governments justify their ability to rule by simply asserting their right to rule. Charismatic dictatorships are typically young governments, coming as a recent change, and rely on the leader(s) to supply head of government.

World Law (L)

Mainline has an extreme law level which covers every area of interaction. Laws are complex, detailed, and difficult to understand. Every interaction with the government requires an Advocate. Law enforcement is omnipresent and strict. Legal proceeding can take months to years to resolve and may involve dozens of people. A few worlds with this law level may be a Red Zone and others will be an Amber Zone. All objects specifically manufactured as weapons are typically regulated or prohibited (with no exception for private residences; visiting starships are only protected so long as they stay within designated starports and approach corridors). Civilian movement is rigidly controlled. Travel documents are frequently checked, and destinations must often be declared when traveling substantial distances across the world.
