Risek has a population between 10,000 and 10 million sophonts, lacking the industrial base to be completely self-supporting. It is a member of Third Imperium in the Rhylanor Subsector of Spinward Marches Sector and in the Domain of Deneb. Risek, as a member world of the Third Imperium, holds the estate of an Imperial knight, a member of the Imperial Nobility charged with overseeing the world. This world has a nearby Imperial Naval Base, capable of handling warships.

Astrography & Planetology

Risek is a member of the Spinward Main.

A brief summary would describe the Risek system as a small, chilly, rock-and-ice ball with a booming interstellar "pass through" trade market.

System Data

The Risek system is characterized by its ancient, binary star system. The main central star, Orb, is a small red star orbited by a red dwarf, Ball. System age is roughly 7.5 billion years.

Geography

The planet itself is less than inviting. It has light gravity (.37g) and a very thin, tainted atmosphere that requires a combination mask-respirator. Equatorial temperatures average 10°C, rising to 20°C in the summer and diving to -10°C in the winter. Axial tilt is 20 degrees. Most of the planetary water is locked in the polar ice caps. Weather, such as it is, includes constant high winds, with thin precipitation on occasion. Geologically, it is an old world with broad plateaus and few mountains. The high plains are hard-pan desert.

Notable Creatures

Several interesting microbes have been found on the surface.

Risson

A large gas giant with a relatively sparse family of moons.

History & Background (Dossier)

Prior to the Fifth Frontier War, the Naval Base hosted elements of the 212th Fleet, and after the war was hosting elements of the 23rd Fleet.

Imperial High (Landed) Nobility

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

• It holds the estate of an Imperial knight.

Basics

The small population of this world largely live in orbital space arcologies, each of which maintains it own system of government and is in "coopitition" with the others.

There are a total of 5 large arcologies:

• Risek-Central,
• Spinward-1,
• Spinward-2,
• Trailing and
• Alexandria.

Each system maintains a downport of various sizes and abilities on the planet itself, and is associated with a handful of "shallow" arcologies. The orbital arcologies maintain an effective defensive capability in and of themselves, and typically have 2-4 lightly armed SDCs for "emergencies". The SDC armament is closely monitored by the Naval authorities.

Government

Risek is an independently administrated system.This system is governed by an Imperial Baron, who maintains an official residence at the local Naval base, and minor residences on each of the arcologies and the planet. Strategically, it underpins the defenses of the Aramis and Regina systems. As such, Risek has a full, and well-equipped Naval Base.

Economy

Population 45,000

Economically, the planet has been mined extensively for lead and other heavy metal deposits in deep mines. Many of the ancient, shallower mines have been consolidated into underground arcologies. These "shallow" arcologies have living quarters with augmented gravity areas, though the reliability, and the settings, of the systems vary.

The main wealth of the system comes from its location. There is a large amount of Jump-1 traffic through Risek, and each orbital arcology competes to grab and hold as much of the trade associated with that traffic as it can. The laws, cultures, subcultures, local politics and random events make this port a dynamic and confusing experience.

Culture

Socially, the peoples of the Risek system are balkanized. Each arcology, whether orbital or "shallow", has its own distinct cultural flavour and strong group identity. Since the groups are separated by hundreds of kilometers or by hard vacuum, there is little fear of military aggression, but there is a strong sense of competition in the inter-arcology sports system. Visiting merchants from other arcologies and even the occasional tourist are also treated with suspicion. All arcologies have strict weapons restrictions.

In the "shallow" arcologies, agoraphobia has been a common mental illness in some sections. The surface is rarely visited by the citizenry, excepting organized youth groups and individualists. Those people raised on the planet have a love-hate relationship with the orbital arcologies. While fascinated by the idea of going into orbit, most will not accept a ride up, preferring to remain "inside".

The orbital citizenry typically considers itself cosmopolitan, having frequent contact with visitors passing through the system. However, there is an expectation of "loyalty". If a merchant enters the system and does business at Risek-Central, that fact will be noted. It will also not be taken lightly, if the merchant decides to dock at Alexandria the next trip in.

Recent History

The current Baron, Admiral Romeo Bianchi, is an experienced administrator with naval experience. He is an older gentleman at 65 years old, but in good health. He attempts to govern with a light hand, not involving himself in local politics unless they affect the system as a whole. He is known to be on good terms with the current Celepinan Count, Knowln.
