Mainworld Data
Mainworld Size (S)
Yalu is a Meso World between 8,800km and 10,400km in diameter. The world has a standard gravity between 0.6G and 0.8G. The horizon will appear about 4.4km away.
Mainworld Atmosphere (A)
Yalu has a pressure of 0.71 to 1.49 atmospheres. A Standard Atmosphere does not require survival gear and will likely be easy for most sophonts to breathe.
Mainworld Hydrosphere (H)
Yalu has 45-55% of its surface covered by liquid water. Wilderness refueling is possible.
Mainworld Geography and Topography
No centrally held map of the world exists within AAB Library Data records.
Yalu (formally The World of Yalu) is a small-standard-sized world with a very clean, standard atmosphere, 2 large oceans, and polar ice-caps.

History & Background / Dossier
No information yet available.
World Starport
Yalu 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 Technology Level
Yalu 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.
- Space: Advanced interplanetary spacecraft (System Craft).
- FTL: Jump Drive-3.
World Government
Yalu is governed by a Religious Autocracy. This is a direct theocracy where the government head is a single person who is also the head of the religious organization. The Church hierarchy also serves as the government bureaucracy.
World Law Level
Yalu 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. Most worlds with this law level may be an Amber Zone or 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). All aspects of life rigidly controlled. There is no difference between the police and the military. This world is a full-fledged police state. Oppression is legalized, though not routine.
The religious philosophy has a environmental element that has legally banned pollution of the environment.

World Economy
The environmental decisions have historically greatly impacted the economic and technological advancement on Yalu, until the import of the Tech-C fusion reactors.

World Demographics

World Culture
Due to religious-society pressures, the population of Yalu ballooned early causing a state of continual near-starvation. Nearly all resources were historically focused on providing adequate food, shelter, and clean water by a well-meaning, but religiously-rigid Church of God (called: Yalu).
With recontact, the religious government immediately embraced Tech-C technologies, and has been enthusiastically implementing advanced power grids, agriculture, aquaculture, and heavy-grav transport. It is still attempting to maintain its historical level of control, but is now constantly debating opening or loosening aspects of its rule-set now that the threat of perpetual starvation is receding.
Urbanization
Rigidly spaced urban centers near water sources are the general rule. These cities are now being updated to Tech-C standards, with some historical preservation efforts.
