History & Background / Dossier
The Trelyn Interdiction Corps is responsible for the protection of Atrephar.
To comply with the terms of its Imperial charter, the Allarton Corporation that underpins the Trelyn Domain is theoretically limited to operating in the Trelyn Subsector. Domain operations in Coos Subsector are run by its wholly-owned subsidiary, the Pan-Melesien Company.
The locals have had contact with offworlders, first contact by IISS explorers taking place in 335. The Atrephari greeted them with indifference. The nature of this world makes direct contact difficult; most study has been with remote probes observing from a distance or the surreptitious excavation of abandoned hives.
World Starport
Atrephar does not have a starport. The Class X Starport is an indication that no starport exists in the system. There are no facilities or services available, and no site marked for landing.
World Population (P)
Atrephar has a population of 50,000,000 sophonts (tens of millions).
- The population consists entirely of Atrephari.

Atrephar possesses a Technology Level of TL–8.
- Common Communication technologies for this TL include: Fiber optics, improved telephones, and satellite communication and data networks.
- Common Power Generation technologies for this TL include: Improved geothermal and improved batteries.
- Common Transportation technologies for this TL include:
- Land: Advanced automobiles.
- Water: Triphibians and early artificial gills.
- Air: Improved helicopters and hypersonic jets.

World Government
Atrephar is governed by a Charismatic Dictatorship. Charismatic governments justify their ability to rule by simply asserting their right to rule.
A planetary 'Grand Marshal' appears to have command authority over all 50 million Atrephari. The Grand Marshal -- who appears to be the same individual even across centuries -- responds to alien attempts at building relations with simple statements that its people aren't interested in what happens "above the clouds".
World Military
It is unclear what military capability the Atrephari have.
