Hydronaut 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 Alpha Subsector of Theta Borealis Sector.
- This is a temperate world, with a climate of pleasant, average temperatures, considered to be an ideal or near-ideal environment by many different sophont species.
- This die back world was once settled and developed, but the inhabitants have either died off or left leaving behind the ruins and remnants of their civilization.
- It is the former homeworld of the Halkyon, an extinct minor race.

- The world orbits beyond the stars Jump Shadow.
Mainworld Size (S)[edit]
Hydronaut 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)[edit]
Hydronaut has a pressure of 1.50 to 2.49 atmospheres. A Dense Atmosphere requires no survival gear although it may be hard on sophonts not accustomed to it.
