Mainworld Data[edit]

Mainworld Size (S)[edit]

Gabrael is a Meso World between 7,200km and 8,800km in diameter. The world has a standard gravity between 0.4G and 0.57G. The horizon will appear about 4km away. The planet is 7750km radius and 24350km circumference.
It has a gravity of 0.65G.
Day Length: 28 hours
Orbital Year: 198 days

Mainworld Atmosphere (A)[edit]

Gabrael has a pressure of 0.71 to 1.49 atmospheres. While a Standard Atmosphere does not require survival gear this atmosphere also contains an unusual taint such as such as disease, a hazardous gas mix, pollutants, or sulfur compounds which requires the use of a Filter Mask. Some taints may require more protective equipment. TL–3 or more advanced survival gear is required to settle this world. The atmosphere is tainted with the local equivalent of pollen which can cause an extremely unpleasant reaction when inhaled. The average temperature is 18 Celsius.[2]

Mainworld Hydrosphere (H)[edit]

Gabrael 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[edit]

Gabrael’s startown is named Tsabad[3]. It lies on the Gamago River and lies twenty kilometres from the starport, to which it is connected by gravitic lift rail[4]. Tsabad consists of a warehouse district, an urban core, and a corporate centre. The corporate centre includes a number of Gravitic buildings, the most notable of which is the Knaegu Ghouk[4]. The prestigious Esali College[4] is also located in the core of the town.

To the north of Tsabad (upstream on the Gamago) lies the town of Tenjann and (beyond Prisma Canyon, in the Benjacquin Highlands) is the small town of Feyr[5]. Feyr is the home of Hallin Products[3], a food processing firm, and the obscure Dreyla Standard Systems[3], a company dealing in robotics.

Mainworld Map[edit]

Map as at 1105



No native fauna of Gabrael flies. All flying creatures on the world are imports (e.g. Chicken). n.b. The Flying Drynet, native to the eastern plains, glides rather than flies and cannot maintain or gain altitude.

The Muugagen Pigbird has gone feral and is now found wild on Gabrael.[2]

There has been an historic trade in Doyle’s Eel on Gabrael, but these creatures are illegal, dangerous and (probably) only being kept by limited specialist collectors.[6]


Nyflan's Fern[7] is a psionic plant that eliminates appetite in nearby creatures - thus ensuring the plant's safety - or just makes you feel happy. This is found in a number of poorer houses on Gabrael but is not native.

Calabaa Trees are grown in plantations on Gabrael and the resulting drink, "Calabaa", exported to the subsector.

Sensitive Umoth reacts badly to Human contact. The oils from the skin transferred during an unprotected human contact tend to cause the plant to die within a few days. Other varieties of Umoth don’t have this reaction.

History & Background (Dossier)[edit]

Imperial High (Landed) Nobility[edit]

Gabrael, as a member world of the Third Imperium has a member of the Imperial Nobility overseeing the world.

The Abandonment saw the Knight of Gabrael evacuated by the IN in 1135, leaving behind a seneschal to oversee the family interests.

World Starport[edit]

Gabrael 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.
The starport is 20km from Tsabad and connected to it by monorail.[4]
This starport's highport is owned and operated by Ling Standard Products.
The highport pays very little tax to the Government of Gabrael, yet starport related income is still the major income for the planet.
The downport has minimal facilities, serving mainly as a transfer port for agricultural goods. Most craft based at the downport are Agricultural Haulage shuttles, with a few passenger and general cargo vessels[8].

World Technology Level[edit]

Gabrael possesses a Technology Level of TL–12 or TL-C in Hexadecimal Notation.

World Government[edit]


Gabrael is governed by a Representative Democracy where government leadership is representatives elected by eligible voters. What determines an eligible voter varies. The representatives determine policy, including selecting members of the bureaucracy. There can be referendum, votes by eligible voters on specific subjects.

World Law Level[edit]

Gabrael 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. All firearms except shotguns, and anything more destructive, are typically regulated or prohibited.

World Military[edit]

1 Battalion

World Economy[edit]

Gabrael was the centre of a wide trade network across 4 sectors. The transport was not always owned by the planet's businesses, but the traders went to many places on many state's shipping lines. It was a non-industrial world.

Trade Data[edit]

Lurent planetoid ships could be found (trading) in the inner system or (refuelling) in the system’s Oort clouds[9].

Agricultural Sector[edit]

Visitors could be forgiven for thinking that Gabrael has pretensions of being an Agricultural world but only a small area (near the starport and capital) is intensively farmed. This provides more than enough food for the population and for sale to/via the highport operators[10].

World Demographics[edit]

Gabrael has a population of 1,000,000 to 9,999,999 sophonts (millions).

  • This is a Nonindustrial World, too small to support the complete chain of production of most goods from start to finish.
  • Most examples of this type are capable of resource extraction but lack an industrial base, in particular factories, to make use of the resources.

Approx 4,000,000

World Culture[edit]

Gabrael is renowned for its level of social equality: Vargr are very comfortable relating with Imperial humans. Many enter professions where the two races interact.

There were a small number of Droyne working on the Planet[3], but this was not their permanent residence - this was not a Droyne world.

On Gabrael, it is considered polite to bring a gift to any prospective employer.[2]

The high-class women on Gabrael tend to employ Contract Fathers when looking for children. [11]


Tsabad is the starport for Gabrael and over 99% of the population live within 500km in 1105.


The architecture of Gabrael includes internal over-pressure using filtered air and air-lock style doors.

The centre of Tsabad included floating offices.
