History and Background

Yolyetau is the capital of the Hlyueawi, an Aslan clan and leader of its own Tlaukhu bloc.

World Starport

Yolyetau has a Class A Starport, an excellent 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 other kinds of repair, and construction of both starships and non-starships. Most ports of this classification have both a Highport and a Downport.

World Population (P)

Yolyetau has a population of 70,000,000,000 sophonts (tens of billions).

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

World Languages

• Trokh: The universal language of the modern Aslan monoculture.
  • Aslan Languages: Note that some Aslan clans retain obscure or archaic languages for personal use in addition to Trokh.

Urbanization

Aslan architecture tends to the organic and the rounded. They favour artistry over efficiency in the design of their buildings -- every Aslan structure is different. Even in mass-produced housing, residents will strive to make their territory uniquely theirs.

• Since Aslan descend from predators and enjoy open terrain, their buildings often feature both open rooms of great size and a number of concealed rooms, balconies, hidden passageways and hideaways.

World Government (G)

Yolyetau is governed by a Civil Service Bureaucracy. The leadership of the government takes another form (democracy, dictatorship, oligarchy), but the bureaucracy leadership influences policy. The government leadership may select the bureaucracy leadership, but not its membership. Usually the governmental leadership is divided, or incapable of setting policy, and the bureaucracy provides a stabilizing influence. This ruling bureaucracy may be the full government bureaucractic apparatus or a section with limited jurisdiction but considerable influence, like the military.

The titular leader of the planet is Hlyueawiko.

World Law Level (L)

Yolyetau has a high law level with laws covering many areas of interactions of people, corporations, and the government. A few worlds with this law level may be Amber Zones. Any interaction with the judicial system requires an Advocate trained in the local legal system. Law enforcement is present almost everywhere, either as people or via technology. Legal proceedings can take weeks to months to resolve and involve a dozen or more people. All objects specifically manufactured as weapons are typically regulated or prohibited (outside private residences or visiting starships).

Criminal acts are rare but not unheard of in Aslan society. Crimes are different from the insults or slurs that provoke duels, and are classified into three categories: crimes of passion, crimes with victims, and crimes of honour.

• Crimes of passion involve misbehavior prompted by temper, anger, or provocation. The accused is judged by the head of the family, pride, or clan involved.
• Crimes with victims involve taking money or items of value, or violating the person of another for profit (kidnapping, terrorism, piracy). General practice is to have an impartial earleatrais consider the case and present findings.
• Crimes of honour involve failure to observe the rituals established for social behaviour. Judgement is made by the pride or clan head, depending on the severity of the crime. Crimes of honour are the most serious in Aslan society; in practice, most are never tried as a duel to the death occurs first.

World Technology Level (TL)

Yolyetau possesses a Technology Level of TL–12 or TL-C 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.
