Derchon has a trace atmosphere and the little amount of surface water is in a frozen state. The system supports a population in between 10 million and one billion sophonts. It is a member of Third Imperium in the Lunion Subsector of Spinward Marches Sector and in the Domain of Deneb. Derchon, as a member world of the Third Imperium, holds the estate of an Imperial knight (the Imperial representative to the world) and the fiefdom of a marquis. Both are members of the Imperial Landed Nobility who oversee affairs regarding the world at an Interstellar and Imperial level. This world contains an Imperial Scout Base, capable of handling Scout Service starships and personnel.

• Derchon is a member of the Spinward Main.

System Data

The worlds of the system have been surveyed. They consist of:

• The mainworld.
• x3 secondary rocky worlds.
• x1 gas giant.

Mainworld Data

Mainworld Size (S)

Derchon 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.

Mainworld Atmosphere (A)

Derchon has a pressure of less than 0.1 atmospheres which requires the use of a Vacc Suit. TL–8 or more advanced survival gear is required to settle this world.

Mainworld Hydrosphere (H)

Derchon has 15-25% of its surface covered by ice, either in vast sheets or contained deep within craters or fractures on the surface. Wilderness refueling is possible. Water for the inhabitants can be got by mining and melting ice.

• The surface of the world is composed of a crust of ice many kilometers thick.
• Much of the surface is cratered and covered in thick layers of regolith and dust of meteoric origin, leaving only a part of the icy outer shell exposed.
• Below the outer icy shell there may be a world-ocean of liquid water.

Mainworld Geography and Topography

No centrally held map of the world exists within AAB Library Data records.

(Blank map, vacuum world.)

History & Background (Dossier)

Point of Interest: Derchon Anomaly

In early 1102, an unidentified object transited the outer reaches of the Derchon (Spinward Marches 2024) system, following a roughly Coreward-Coreward-Trailing vector. Called the Derchon Anomaly it was traveling at such high velocity (estimated 0.12C) that no ship could possibly intercept it.

Sensor data revealed that that:

1. The object had a high albedo.
2. It was spinning or tumbling rapidly.
3. Its mass was in the 1,000-2,000 ton range.
4. It was highly radioactive.

Although the object was not under acceleration, these facts argue strongly in favor of some type of artificial construction. Investigation of this object by the Derchon Anomaly Intercept Mission (DAIMISS) in 1103 revealed it to be a derelict spacecraft associated with the legendary Ahaja Bucherei and his fellow Dru'mhilla exiles.
