Jerdak is a barren water world with no overt population, government, or law level.

  • Its surface is 90% or more covered in an ocean of water.
  • Any inhabitants of this world would need to live on the roughly 10% of exposed land mass, in underwater colonies, on city ships, or similar arrangements.
  • This world could be populated if anyone had an inclination to do so...
  • It is an unclaimed Non-Aligned world located in the Encha Subsector of Fulani Sector.
  • 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.

Mainworld Size (S)[edit]

Jerdak is a Meso World between 12,000km and 13,500km in diameter. The world has a standard gravity between 0.8G and 1.1G. The horizon will appear about 5.1km away. Vessels with 1G of thrust should check with local starport authorities before attempting to land using emergency power.

Mainworld Atmosphere (A)[edit]

Jerdak has a pressure of 0.10 to 0.42 atmospheres. The very thin pressures require a respirator or Oxygen Mask. TL–5 or more advanced survival gear is required to settle this world.

Mainworld Hydrosphere (H)[edit]

Jerdak has 95-100% of its surface covered by liquid water with only a few islands and archipelagos. Wilderness refueling is possible. Such worlds are Water Worlds or Ocean Worlds.

  • The vast oceans are storm-wracked and turbulent.
