Dhaun is a barren vacuum world with no overt population, government, or law level.

• These worldlets warrant hazardous environment precautions.
• Life in a vacuum requires great discipline. After all, it only takes one forgotten seal on a vacuum suit to spell death.
• This world could be populated if anyone had an inclination to do so...
• It is an unclaimed Non-Aligned world located in the Omusa Subsector of Tirell 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.

Description (Astrography & Planetology)

The Dhaun system was officially surveyed by the University of Tal Varisa Deep Sky Program.

• The results of the survey are available as the DSP Listing, a comprehensive star catalog first published in 5550AD.
