Darrian has a comfortably breathable atmosphere. The system has a population between 1 and 10 billion sophonts. This world contains an archaeological site with artifacts suspected to be from the now-vanished Ancients. This is a high technology world with available technology over the standards for Charted Space. It is a member of Darrian Confederation in the Darrian Subsector of Spinward Marches Sector. Darrian does not have the presence of Imperial Landed Nobility. This is the homeworld of the Daryen, a Minor Human Race. They are 80% of the world's population. Less than 10% of the world's population is the Major Race Aslan.

System Data

The Darrian system was ravaged by a tragic accident many years ago known as the Maghiz, a series of apocalyptic solar flares of disputed origin.

Darrian is a small world with low gravity.

Mainworld Data

Mainworld Size (S)

Darrian is a Meso World between 5,600km and 7,200km in diameter. The world has low gravity between 0.32G and 0.46G. The horizon will appear about 3.6km away.

Mainworld Atmosphere (A)

Darrian 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)

Darrian has 25-35% of its surface covered by liquid water. It has a few small seas. Wilderness refueling is possible. Water for the inhabitants will be recycled.

Mainworld Geography & Topography

The surface of Darrian is divided by long, high mountain ranges into 5 basins. Each basin is centered on a sea fed by rivers draining the surrounding country; thus, basins are the equivalent of continents. Each basin also contains the remains of a "Flame Pit", beds once two kilometres wide of glowing coals fed from below by geothermal action. Around each Pit stands the remnant of a Father tree Orchard. These trees are circular but have a cross-section of about 5 square meters. In early Darrian history, the trees were used as homes by Darrian families.

The main five basins are:

• Abh
• Boyr
• Nyadh
• Rimb
• Zlodh

Native Lifeforms

Darrian is rich with complex lifeforms. There is some evidence of extensive outside interference with the planet's indigenous biosphere. Lifeforms include:

• Father tree
• Yorin: A falcon-like avian

Native Sophont: Daryen

Darrian is the homeworld of the Daryen, a Minor Human Race.

History & Background (Dossier)

The Te-Zlodh name for this world is Daryen, which means "world" or "home."

Darrian is the technological centre of the Darrian Confederation, as Mire (Spinward Marches 0527) is the political center. Scientists are in charge of the government and industry, paying careful attention to possible consequences before allowing changes. There are restrictions on the export of any artifacts of pre-Maghiz culture that still remain on Darrian.

The military force of the Darrians is known as the Darrian Navy.

World Starport (St)

Darrian 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)

Darrian has a population of 2,000,000,000 sophonts (billions).

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

World Demographics

• Aslan: Around 10%
• Darrian: Around 80%
• Solomani: Around 10%

Urbanization

Cities include the following:

1. Drozh
2. Kilulga
3. Pororda
4. Rebhar
5. Zehn Nyak
6. Zlodh

The most obvious of Darrian high-tech symbols have been the pictures of the world's grav cities. Four major cities on Darrian (one in each basin except Zlodh) are grav structures held aloft by grav modules, freeing them from the ordinary constraints of gravity on architecture. Rebhar was constructed as a mining construct, and it gradually makes its way along the mountainous rim of the Boyr Basin extracting metal ores from the rugged rock faces. Pororda, now a tourist center in the Rimb Basin, was originally designed as a sea farming center; it hovers above the waves of the Rimb Sea and provides amusement and recreation facilities. Kilulga, in the Abh Basin, hangs in the upper atmosphere above most of Darrian's cloud cover. Zehn Nyak in the Nyadh Basin is a migratory city, moving among seven different sites as the markets and seasons change.

Zlodh technology made possible a great many wonders on Darrian. While many marvel at Darrian's flying cities, an equal wonder is the undersea city of Zlodh. Created as the bloom of grav technology spread across Darrian, it lies on the floor of the Polar Sea beneath the North Polar icecap.

A network of grav generators mounted in a latticework of metal struts keeps the seawater at bay. Unlike the classic domed undersea structures, Zlodh's lattices snake in hundreds of directions, bulging out to cover settlements and factories, narrowing in again to cover transportation lines, small housing developments, and businesses. The grav generators constantly repel the waters above the lattice, creating strong currents around all of the city. Since the currents also carry waste heat upwards away from the city, the icecap above it has melted.

Transportation to Zlodh takes two forms: the undersea tube line, a 500 km rail system which connects with Drozh, a port city in the southeastern Zlodh basin; and the air terminal on the icecap directly above Zlodh with direct transport on a vertical grav shaft to the city 2000 m below.

The city of Zlodh has two major attractions: the sea farms and the University of Zlodh. The sea farms are a major food resource for Darrian and provide a wide variety of tasty seafoods.

World Technology Level (TL)

Darrian possesses a Technology Level of TL–15 or TL-F in Hexadecimal Notation.

• Common Communication technologies for this TL include: Meson Communicators and Pseudo Reality Communications.
• Common Power Generation technologies for this TL include: Miniature super-batteries, improved collectors, and advanced Fusion+.
• Common Transportation technologies for this TL include:
  • Land & Water: Advanced gravcraft.
  • Air: Advanced gravcraft and speeders.
  • Space: Advanced gravcraft and G-Carriers.
  • FTL: Jump Drive-6.
• Technically, Darrian is classified as TL-16, and therefore has among the highest technology achievements in Charted Space. Though this is entirely due to recovered artifacts, it cannot be denied that Darrian society is full of brilliant scientists.

World Law (L)

Darrian 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.

• The Taledh Code is the basis of Darrian law.

The following corporations do business here:

• Pthanth Shipyards
