Jump map from Travellermap.com

Barl is a nonindustrial water world, which has 90% or more of its surface covered in an ocean of water.

• The inhabitants of this world live on the roughly 10% of exposed land mass, in underwater colonies, on city ships, or similar arrangements.
• As a nonindustrial world, 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.
• It is a Non-Aligned world dominated by human sophonts located in the Tangal Subsector of Mavuzog Sector.

• It orbits the secondary star.
• This world is a "Twilight Zone World", a planet that is tidally-locked to its star. It has a hot side that permanently faces the star, a cold side that permanently faces away, and a narrow twilight zone in-between.
• This world toils under the control of a military government with conditions reflecting that situation including curtailed civil rights and limited freedoms.
• About 40% of the population is composed of Droyne.
• About 60% of the population is composed of baseline humans.
