Mainworld Data

Mainworld Size (S)

Lyo is a Meso World between 12,000km and 13,500km in diameter. The world has a standard gravity between 0.8G and 1.1G. The horizon will appear about 5.1km away. Vessels with 1G of thrust should check with local starport authorities before attempting to land using emergency power.

Mainworld Atmosphere (A)

Lyo has a pressure of 1.50 to 2.49 atmospheres. A Dense Atmosphere requires no survival gear although it may be hard on sophonts not accustomed to it.

Mainworld Hydrosphere (H)

Lyo has 85-95% of its surface covered by liquid water with a few small continents, and a number of islands and archipelagos. Dry land is limited. Wilderness refueling is possible.

History & Background (Dossier)

Lyo is an important trade bridge between the Union of Harmony and the Aslan Hierate.

World Starport (Sp)

Lyo 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)

Lyo has a population of 20,000,000,000 sophonts (tens of billions).

• High Population Worlds like this tend to have huge consumer markets.

World Demographics

• Aslan, 80%
• Human, 15%
• Other (Ulane, Ormine, Virushi, etc.), 5%

World Government (G)

Lyo is governed by a Non-charismatic Dictatorship. This is a continuation of the charismatic dictatorship, where the original leadership has died or retired and been replaced by allies or protégés. The justifications for the original change in government remain as well as the assertion of rights to rule.

World Law Level (L)

Lyo 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 world with this law level may be an Amber Zone or a Red 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. There is no legal concept of privacy (save for those who can claim necessity for official government business). The police are free to inspect anyone and anything at any time.

World Technology Level (TL)

Lyo possesses a Technology Level of TL–11 or TL-B 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 & Air: Personal G-Tubes and advanced gravcraft.
  • Space: Advanced interplanetary spacecraft (System Craft).
  • FTL: Jump Drive-2.
