Surtun is a non-agricultural, pre-industrial vacuum world, which warrants hazardous environment precautions.

• Life in a vacuum requires great discipline. After all, it only takes one forgotten seal on a vacuum suit to spell death. Those who survive tend to be very methodically-minded and attentive to small detail.
• It is unable to produce quality foodstuffs and must import them.
• It requires extensive imports of outside technology to maintain a modern, star-faring society. The need to import most manufactured and high technology goods drives the price of these goods up in the open market.
• Its economy and population are slowly growing and living conditions are expected to improve in the near future barring outside forces.
• This world is a member of the Trelyn Domain (the Duchy of Trelyn) located in the Coos Subsector of Vanguard Reaches Sector.

• This is a "Puzzle" world designated as an Amber Zone. Caution is advised since the world has an environment, laws, customs, life forms, or other conditions that are not well understood and might be a danger to a visitor.
• This world-system has a Military Base, usually associated with military ground forces, which may be located on or off-world.
• This world is a colony of Karelian.
• It is a member of the Trelyn Main.

History & Background (Dossier)

Surtun is a Puzzle World and is designated as an Amber Zone. It presents particular risks and dangers due to the environment or native life forms, laws or customs, or other conditions that are not well understood.

• Visitors are advised to act with caution.

To comply with the terms of its Imperial charter, the Allarton Corporation, the Imperial corporation underpinning the Trelyn Domain, is limited to operations exclusively within the Trelyn Subsector of Vanguard Reaches Sector. Allarton officials and representatives may occasionally conduct business on other worlds of the Domain.

• Corporate operations in other areas of the Vanguard Reaches are conducted under the wholly owned Pan-Melesien Company.
• Corporate operations in the Far Frontiers Sector are conducted under the wholly owned Artesian Company, based at Yster.

Both subsidiary companies may be active on worlds far beyond their official operating areas.
