Xeval is a barren hellworld, which would challenge the survival of nearly any sophont in Charted Space if it weren't already barren.

• As a barren world, it has no overt population, government, or law level.
• Hellworlds often offer daily, and sometimes hourly, life-threatening situations to their inhabitants.
• This world could probably be populated by very determined colonists if any had an inclination to do so...
• It is an unclaimed Non-Aligned world located in the Surgian Subsector of Astron Sector.

• It is a mainworld which is a satellite of either a gas giant or another world.
• This is a frozen world, with a climate of extremely low temperatures.

System Data

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

• The mainworld.
• x4 secondary rocky worlds.
• x5 gas giants.

Mainworld Data

Xeval is a satellite of a gas giant.

The mainworld and its gas giant primary orbit within the outer system.

• They receive very low levels of stellar energy.

Mainworld Size (S)

Xeval is a Big World between 13,600km and 15,200km in diameter. The world has a standard gravity between 1G and 1.3G. The horizon will appear about 5.4km away. Vessels with only 1G of thrust should avoid landing on this world.

Mainworld Atmosphere (A)

Xeval has an Exotic Atmosphere and possesses an unusual gas mix which requires the use of oxygen tanks. Additionally, protective suits, while not necessary, are recommended. TL–8 or more advanced survival gear is required to settle this world.

Mainworld Hydrosphere (H)

Xeval has no free-standing water or ice on the surface. What little water or ice exists is heavily tainted with other substances, which makes it dangerous, corrosive, or toxic. Wilderness refueling isn't possible on this world. Water for the inhabitants needs to be imported and extensively recycled. These worlds are Hell Worlds.

• The world has an arid, hostile surface environment.

Mainworld Geography and Topography

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

• Locally, detailed maps may be available.
• Verified updated charts are constantly sought.
• Detailed survey data commands premium prices.

Native Lifeforms

Primitive exotic native life occupying a few niche habitats. Its metabolic functions help regulate the process of atmospheric renewal.

History & Background (Dossier)

• Information about the system is limited.
• The resources of the system are untapped.

Note that social data, though only 40 years old, may be out of date: previously undocumented groups may now inhabit the system and maintain their own culture, forms of government, and systems of law.

• Verified updated data is constantly sought.
