Jump map from Travellermap.com

Byrole is a poor, 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 Vilian Subsector of Astron Sector.

• This is a hot world, with a climate of high temperatures.

System Data

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

• The mainworld.
• x5 secondary rocky worlds.
• x3 gas giants.

Mainworld Data

The mainworld orbits within the star's Habitable Zone.

• It lies within the zone's warmer inner H+ region
• It receives higher levels of stellar energy.

• The world orbits inside the star's Jump Shadow.

Mainworld Size (S)

Byrole is a Meso World between 5,600km and 7,200km in diameter. The world has low gravity between 0.32G and 0.46G. The horizon will appear about 3.6km away.

Mainworld Atmosphere (A)

Byrole has a pressure of 0.10 to 0.42 atmospheres. The very thin pressures require a respirator or Oxygen Mask. This atmosphere also contains an unusual taint such as disease, a hazardous gas mix, pollutants, or sulfur compounds, which requires the use of a Filter Respirator Combination Mask. Some taints may require more protective equipment. TL–5 or more advanced survival gear is required to settle this world.

Mainworld Hydrosphere (H)

Byrole has 15-25% of its surface covered by liquid water or ice. There may be a few small seas. Wilderness refueling is possible. Water for the inhabitants needs to be imported and extensively recycled. These worlds are Hell Worlds or Poor Worlds depending on their atmosphere.

• Much of the surface is an arid, hostile environment.

Satellites:

Byrole retains a small vacuum moon.

• It orbits once every few weeks.

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.

(Placeholder chart, predominantly dry world.)

Native Lifeforms

Primitive, specialized native life filling a few specific ecological niches. Its metabolic functions help regulate the process of atmospheric renewal.

History & Background (Dossier)

The system is a remote wilderness. Many of the planets and moons within it may never have had an intelligent being visit them.

• 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.
